Habitat. — Atlantic District ! (Mass. to Ga.) Rare. 



We are informed that this very distinct species has been 

 figured by Abbot on an unpublished Plate belonging to the 

 work on the Lepidoptera of Georgia. 



The larva of C. sepnlcralis, has been frequently taken by 

 Mr. James O. Treat upon the common Yellow Pine, in the 

 vicinity of Lawrence, Massachusetts. Its discoverer writes, 

 that he finds it " difficult to rear, as most are ichneumonized, 

 probably on account of the poor protection afforded them from 

 their enemies by the scanty foliage of this Pine." 



We have alcoholic specimens of this larva, which, while 

 sharing the same generic characters with that ot C. regalis, is 

 quite distinct. Compared with alcoholic specimens of this 

 latter species in their last moult, the larva of C. sepnlcralis is 

 smaller, and of a general paler coloration. The spines are 

 nearly smooth, with obsolete spinules, pale, slender, and uni- 

 colorous. It is uncertain that these specimens, furnished by 

 Mr. Treat, are in their last moult, but we presume it to be the 

 case. The head in C. sepulcralis is larger, while in the rela- 

 tive size and sculpture of the supra-anal and pleural plates on 

 the terminal segments, the larvae of the two species very nearly 

 agree. The lower lateral pair of thoracic spines on the second 

 and third segments (not counting the head as the first), appear 

 reduced in the specimens before us.
