Abstract
This study has included the collecting of specimens, preparation of the material for microscopic examination and the tracing of the process of spermatogenesis in the common squash bug, Anasa tristis (De Geer). Live bugs were kept throughout the summer (1934) on squash vines in Logan and abundant material was obtained. Ninety-four slides showing sections of twenty-one testes from fourteen different bugs were prepared by various methods. The best slides were made from material fixed in Bouin’s solution and imbedded in paraffin. Some were stained with Delafield’s haematoxylin and eosin as a counterstain and others were stained with iron haematoxylin by Heidenhain’s method.
