ADELPHAGROTIS APPOSITA Grote. 



Fifty-eight specimens, July 19, 20, 25, 30, 31, August 3, 4, 5, 6, 7, 

 11, 12, 15, 16, 17, and one from Mr. Cockle's collection July 18. 

 Rather variable. The dark forms have the markings picked out l)y 

 rows of fine white scales, the ordinary lines nearly lost. Eggs were 

 secured from two captive females, but they proved sterile. 



Eggs. — Laid loose, rolling about. Nearly spheroidal, a slight flat- 

 tening at the vertex and base. Ribs distinct, sharp, with rounded hol- 

 lows between, about 36 on a side, diminishing above by confluence. 

 Reticulations fine, obscure, forming square cells. The ribs become 

 small at the vertex and are joined by stri;e nearly equal to them, but 

 run practically to the micropylar rosette, which is scarcely raised: 

 pale yellow^; diameter, 0.7 mm.
