452 ENTOMOLOGICAL NEWS [Dec., 'lO 



The larva of concumbens were rather sluggish and at no 

 stage of their growth did any of them ever rest on the under- 

 side of the breeding jar lid but remained mostly on the twigs 

 even when well grown. 



The larvae of neogama always hide under paper in the bot- 

 tom of the jar. 



The caterpillars of amatri.v, cara, and rclicta often rest on 

 the underside of the jar lid. 



For two or more years, the senior author's experience with 

 larvae of Catocala neogama, piatri.v and cara was anything 

 but satisfactory, however, in 1909, all did well and good series 

 of the moths were secured. The first piatri.v larvae were per- 

 fectly healthy but toward the last of the season there was a 

 considerable loss. Contrary to the experience of 1909, the 

 senior author was able to rear a fine lot of amatri.v larvae and 

 secure a magnificent series of beautiful moths, setting nineteen 

 perfect specimens. 



The dainty coloration of the front wings of some of the 

 female nuri is marvelous. There is no one of the series entirely 

 without all vestige of the oblique black band across the front 

 wing and it does seem strange that the commoner form should 

 be designated the variety in this species. 



Imagoes from larvae bred in doors, appear from one to two 

 weeks earlier than moths from forest feeding caterpillars and 

 it was an easy task the past year to foretell what would likely 

 be in abundance in the woods a week or more later and the 

 senior author was not disappointed in his conjecture that /7m 

 and piatrix would be abundant, for 1910 was preeminently the 

 year of these two moths. Hardly less numerous was cara, and 

 innubens is always plentiful. 



Epione, relicta, vidua, robinsoni and angusi were rather 

 scarce. Neogama, palaeogama and habilis were hardly more 

 abundant. 



Numbers of amatri.v picked up about town would seem to 

 show this species common but the senior author did not see 

 a specimen of it in the woods. It is an abundant moth at 

 Vinton, Iowa.
