| Randomly sampled oothecae of a natural population of Gratiana spadicea from the outskirts of Porto Alegre, RS, were dissected. The overlapping of the egg membranes makes possible to enumerate the eggs in a batch and therefore to relate mortality to position in the ootheca. The ootheca of this cassid provides a spatial refuge for some of its eggs. Successful eggs of G. spadicea amounted to less than one fifth of the total in each batch. Parasitoids and predators were responsible for a high mortality of eggs whatever the size of the ootheca. The main cause of mortality was the eulophid wasp Emersonella ooecia De Santis, 1983. A large proportion of eggs were sucked dry by the mirid Tupiocoris cincticornis (Stal, 1860). The sucked eggs could have contained... |

(D.) histrio (Linnaeus, 1758); D. (D.) maculatus (Laporte, 1832); D. (D) corrosus (Herrich-Schaeffer, 1844); D. (D.) antennatus (Dallas, 1851); D. (D.) gibbus (Dallas, 1852); D.

| Five species are here recognized for the genus Cataulax Spinola, 1837: Cataulax eximius (Stål, 1860), Cataulax froeschneri, n. sp., Cataulax pudens (Distant 1889), Cataulax radians, n. sp. and Cataulax subtiliterconspersus, n. sp. Cataulax pudens is transferred from Architas Distant, 1889, here considered a junior synonym of Cataulax. Cataulax annulicornis Walker, 1868, Cataulax punctipes Walker, 1868 and Cataulax subvittatus Walker, 1868 are considered incertae sedis. |
