| In order to test Piza's conclusions regarding the dicentricity of Hemipteran chromosomes, two species of bugs of the family Coreidae, namely, Anasa sp. and Leptoglossus stigma (Herbst), are studied in the present paper. a) Anasa sp. - The male of this species has 21 chromosomes, that is, 20 pairs of autosomes and a single sex chromosome. The latter divides equationally in the first division of the spermatocytes and passes undivided to one cell in the second division. In this it moves with its longer axis parallelly to the spindle axis and shows fibrillar connections with both poles. Special attention was paid to the behavior of the chromosomes in the anaphase of the spermatogonia. As it was previously stated (Piza 1946 and 1946a) with regard to other... |

| Contribution to the knowledge of some Citrus damaging Hemiptera. This paper deals with field and laboratory investigations on Crinocerus sancius (Fabr., 1775), Leptoglossus gonagra (Fabr., 1775), and. L. stigma (Herb., 1784), all belonging to the family Coreidae, Order Hemiptera. These three species are noxious to several fruits, including citrus. The two Leptoglossus and the damages they cause on oranges have been investigated by several writers in the last 25 years. On the other hand, c. sancius was discovered damaging Citrus only in 1959, increasing in importance since its discovery. Redescription of the adults, bionomical notes, hosts, and so on, are the main purpose of this study. |

| In this paper, some notes on "saúva mata pasto" (paraol ant, Atta bisphaerica Forel, 1908) are presented. This ant is very common in good soils and it is a pest of gramineous plants, mainly com, rice, sugar cane, and so son. In poor land it is too difficult or even impossible to ind it. |
