178 D. W. COQUILLETT. 



simply forms of one and the same species. This species thus gives 

 us additional proof for suppressing the proposed genera Dipalta O. S. 

 and Stomjx O. S., both of which differ from a typical Anthrax, by 

 possessing three instead of only two submarginal cells in each wing. 



3. A. clelia O. S. 



Described as a Stonyx ; synonym Anthrax keenii Coq. 

 71). A. lateralis Say. 



Two of my specimens are from Jamaica. The variety fulvipes 

 Coq. belongs to the present species rather than to alternata. 



7c. A. gracilis Maeq. 



A single specimen from Florida agrees with alternata in having 

 the front tibite provided with bristles, but the claws of the front tarsi 

 are fully three-fourths as long as those of the middle tarsi, whereas, 

 both in alternata and lateralis they are scarcely one-third as long. 

 This specimen is 10 mm. long, very slender and marked nearly the 

 same as lateralis. Of course, there is no certainty that this is the 

 form Macquart had before him when drawing up his description of 

 gracilis, but his name is very appropriate for the present species, and 

 his description also agrees fairly well with it.
