| Mr. J. W. van Nouhuys, Commander of the Government-Marine in Dutch India, presented to the Leyden Museum some pieces of the skin of a big fish (Selachian?), caught in the Moluccas, that are beset with several specimens of a large Penella; in like manner upon different points of the body of these parasites, individuals of the well-known Cirripede Conchoderma virgatum Spengl. have fixed themselves. It is not an easy task to state to what species of Penella our specimens may belong, for though Steenstrup and Lütken ¹) have given us a detailed description and exact figures of four species of this genus, viz. P. sagitta, varians, exocoeti and crassicornis, and afterwards Koren and Danielssen published a rather elaborate paper on a Penella from Balaenoptera... |

| The Mollusks recorded in this paper, have been collected by Mr. J. W. van Nouhuys on Taliabu, one of the larger Xulla-isles, and were presented by him to the Leyden Museum of Natural History, together with a few other species from various localities, amongst which latter are however no new species. As the only record of Mollusks from the Xulla-isles is that of Xesta citrina var. by Wallace, mentioned hereafter in my note on X. halmaherica, I thought it would be interesting to enumerate them all, instead of describing only the new forms. I think the number of species existing in that island will not be exhausted by these 17 species, the more so as the second part of the collection contained several species not represented in the first lot, but the number... |

| Allied to Helota Vandepolli Rits. 1), from Borneo, but broader, more strongly shining and of a brighter, more golden bronze colour above; moreover the punctuation on the head and pronotum is much coarser, that along the middle of the elytra finer, and the yellow spots on the elytra are larger. Length 12 mm. — Above very shining along the middle and of a bright golden bronze colour; along the lateral margins the elytra are greenish; the scutellum is green; the antennae are pale testaceous with the club dark pitchy; the yellow elytral spots are situated between the 3rd and 6th striae and surrounded with black; the anterior pair is subquadrate, the posterior pair slightly narrower (more ovate) than the anterior one. The colour of the underside is pale... |

| This genus was erected by Mac Lachlan [Journ. Linn. Soc. XI, p. 261 (1871)] for a group of Indian species described by Walker [Cat. Brit. Mus. Neur. (1853)]. Mac Lachlan gives but a preliminary review of the synonymy of the species which were all described by Walker in such an unintelligible manner, that it is impossible to judge after his descriptions about their synonymy. Some weeks ago Mr. W. F. Kirby communicated me the Ascalaphidae of the British Museum and among them were three cotypes of Walker, which he kindly had compared. They agree very well with Walker’s descriptions and belong to the species insimulans, immotus and dicax. As the individuals vary very much in colour after the degree of maturity and as the species have a very large geographical... |

| Ritsema Cz., C.. |
| Allied to Helota sinensis Oll. and tonkinensis Rits., but distinguished by the differently coloured prothorax and legs, and, in the male sex, by the want of pubescence in the semiovate impression on the apical ventral segment, and by that of the tuft of long hairs on the inside of the apex of the posterior tibiae. Length 8 mm. — Above rugose in consequence of a very dense punctuation, the sutural streak, however, slightly shining; provided on each elytron with two yellow convex spots and with four rows of slightly raised glossy warts of different shape and size. The colour of the upper surface is dark greenish bronze, the scutellum and the sutural interstices coppery; the anterior lateral angles of the pronotum fulvous; the antennae fulvous, the top of the... |

| In den Mitth. des naturw. Ver. für Neuvorpomm. und Rügen, Band XVI, XIX, XX. und XXV, hat Gerstaecker eine Reihe neuer Arten Planipennia beschrieben, von welchen ich durch die Freundlichkeit seines Nachfolgers Prof. G. W. Müller in Greifswald die Ascalaphiden zur Untersuchung bekommen habe. Obschon G.’s Beschreibungen und Diagnosen wirklich vorzüglich sind, muss ich doch einige Bemerkungen über die Berechtigung seiner Species und Gattungen machen. So hat er nicht immer dem Umstand Rechnung getragen, dass sehr adulte Stücke eine viel dunklere Körper- und Flügelfärbung haben als jüngere Exemplare und dadurch die Beschreibungen früherer Autoren nicht richtig gedeutet. Mangel an Vergleichsmaterial, die grosse geographische Verbreitung vieler Arten und auch die... |
