66 LEPIDOPTERA. 



Of the perfect insects obtained from these larvae, two ^ and 

 two $ , one $ agrees precisely with the specimens received 

 from Herr Mann as " communana,'' whilst the other three 

 scarcely differ from the typical Walilhomiana. They made 

 their appearance May loth and 2oth, June 1st and 11th. 



Var. b. pale yellow, with a dark dorsal stripe (dorsal 

 vessel); head pure honey-yellow. Thoracic shield yellow, 

 with two lateral round black spots in its posterior half, or 

 with the anterior half yellow and the posterior half black, or 

 else entirely black. Warts shining black, large. Anal plate 

 elongate, rounded, with the anterior half yellow, the posterior 

 half black, sometimes it also is entirely black ; immediately 

 behind it is a semicular plate of black chitine, with^2;e long 

 thorns. 



I have hitherto only found this very striking larva twice, 

 namely, on the 12th June, 1867, in the flowers of Orohus 

 tuber osus at Coburg; and on the 31st May, 1871, I found 4 

 specimens on Medicago sativa at Marktsteffc. 



The pupag are paler brown than in the other SciaphilcB, 

 and have at the anal end two fine pointed thorns, at the base 

 of each of which on the ventral side of the pupa is a small 

 horny strip. The few bristles at the anal end are recurved, 

 hook-like. 



The three images, all females, which were developed from 

 these larvae on the 22ud, 23rd and 28 th June, agree pre- 

 cisely with the specimens of Sc. virgaureana received from 

 Herr Mann, who had himself remarked, that to the best of 

 his recollection the larvae were yellow, with black head and 

 black warts. 



Var. c. agrees altogether in colour with the typical Wahl- 

 bomiana-lavva, and has the same large shining black warts, 

 but differs from that very decidedly in that "the black plate of 

 chitine behind the anal plate is furnished with eight thorny
