This lalter consists of a more or F'&- "? less bilobed, large and se- michitinous arc, the poste- rior portion including the vagina and génital orifice. Though I bave termed it bursa copulatrix, it perhaps functions also as a réservoir for eggs at the time of ovipositing. Opening dorsally into the posterior part of the bursa (or vagina) are two large, tubular colleterial glands (CG), uniting in,a common duct at their ba es. Thèse glands lie one on each side along the abdomen, and at the time of egg-laying are pale yellowish. The following are the data for seven spécimens : Eggs laid August 29 1908. Eggs hatched Sep
