310 GEO. H. HORN, M. D. 



This species closely resembles pulchra, but differs in having black 

 legs and a pale clypeus. 



Occurs in the Middle States, Ohio and Dakota. 



17. — C lugubris Say, Jour. Acad. 1827, p. 246.— Color entirely black. 



Male. — Elytra at tip slightly swollen, smoother, deeply impressed. 



Female. —Elytra a little smoother at tip. 



This species is more coarsely and less densely punctured than pulchra 

 or labiata, but agrees closely in this respect with fulvipes, which has yel- 

 low legs and the male elytra tipped with yellow. 



Occurs in the Middle States, Canada and Ohio. 



18. — C collaris Say, Journ. Acad. 1827. — Black, thorax red. Elytra with 

 coarse, deep, sparsely placed punctures. 



Male. — Elytra at tip smoother, not swollen, and with a feeble impression near 

 the suture. 



This species is the smallest of those with the elytra impressed at tip, 

 and is unusually coarsely punctured. It is almost impossible to distin- 

 guish the females from those of term Inalis. 

 Occurs in the Middle States. 



19. — C inconspicua Horn, Trans. Am. Ent. Soc. 1874, p. 42. — Piceous, 

 thorax red, elytra piceous or or rufous. Elytra moderately densely punctured. 



The tips of the elytra are not in any respect different in the two 

 sexes. The only method of distinguishing the male is by the presence 

 of the additional ventral segment. The females might be mistaken for 

 punctu/ata or Lewisii, but the elytra are rather more coarsely and less 

 densely punctured, and the form smaller and more slender. 



Occurs in California and Nevada. 



20.— CJ. vittata Horn, Trans. Am. Ent. Soc. 1871, p. 279. — Piceous, elytra 

 with vitta and side margin pale, often in the female entirely pale. Thorax con- 

 spicuously and moderately densely punctured. Elytra moderately densely punc- 

 tured. 



The sexual characters are entirely wanting at the tips of. the elytra. 



The females have usually luteous elytra and the legs pale. 



Occurs in California. 



CANTHARIS Linn. 



C. mutikita Horn, having the fifth joint of the male antennae exca- 

 vated and somewhat prolonged upwards at its distal end, must be placed 

 between those species which have several joints so deformed (e.g. encera) 

 and those in which the intermediate joints are simply thicker. 



C. desert kola Horn. — At the time of the description of this species 

 (Proc. Amer. Philos. Soc. 1873) I knew the female only and placed it 

 with Group 2. The male is now at hand, and having the intermediate
