124 THE ENTOMOLOGIST. 



form, colour and size, of a rolled-np caniola larva, a circum- 

 stance which greatly increases the difficulty of finding them 

 when thus feigning death. In confinement, as at large, ihey feed 

 exclusively on Leguminosoe, and seek no change of diet, per- 

 tinaciously refusing to touch, and indeed appearing to avoid, 

 the lichens that my solicitude for their well-being had pro- 

 vided. Head narrower than the body ; when perfectly at rest, 

 partially concealed by the 2nd segment. Body of nearly uni- 

 form thickness, but slightly decreasing towards the anal 

 extremity ; the segmental divisions deeply incised ; the 2nd 

 segment has the dorsal surface scabrous behind the head, the 

 scabrous surface emitting bristles which project over the 

 head ; this segment has also two scabrous warts on each 

 side ; the other segments have twelve scabrous warts, that 

 is, six on each side, and each wart emits a fascicle of radi- 

 ating bristles ; four of these warts are strictly dorsal ; two 

 anterior, smaller and approximate ; two posterior, larger and 

 more distant ; the third on each side is large and circular ; 

 the fourth smaller and linear; and the fifth much smaller, 

 and immediately above the claspers when these occur. Co- 

 lour of the head black and shining ; a white spot on each 

 side at the base of the mandibles. Body with a very nar- 

 row black medio-dorsal stripe, bounded on each side by a 

 still narrower and very sinuous gray stripe ; this is followed 

 by a somewhat broader smoky black stripe, and this, again, 

 by a sinuous and irregular orange stripe ; this last contains, 

 and is interrupted by, the second row of scabrous warts ; 

 next on each side follows a broad stripe of smoky black, de- 

 licately tessellated with sinuous gray markings ; this lateral 

 stripe contains the third series of warts, and also the spiracles, 

 which are pale orange ; finally comes a narrow subspiracular 

 stripe of a dingy orange-colour, and this contains a fourth 

 series of warts. The ventral surface is smoky flesh-colour ; 

 the legs and claspers rather less dingy. On or about the 8th 

 of July it spins a slight cocoon at the roots of the clover, and 

 changes to a smooth brown pupa : the moth appears at the 

 beginning of August; the males assemble freely, after the 

 manner of Bombyces, to seek the company of bred females. 

 1 have not only breci this species myself, but have received a 

 number of interesting details, as well as a liberal supply of 

 larviE, from Mr. Birchall. The species has not long been
