134 THE CANADIAN ENTOMOLOGIST. 



exact type o'i Drepana (one of the above six species of Schrank's) is not 

 now in question. In 1868 I did not know the use of Laspeyres's term by 

 Hubner in 1806, and following Stephens, incorrectly used Drepana for 

 our species; but I changed ihis use in the paper above cited in 1874, 

 reverting to the name Platypteryx used by me in my first paper on our 

 species, Proc. Acad. Nat. Sci., Phil., 1862, p. 59. 



ADDITIONS TO THE LIST OF U. S. HYMEN'OPTERA.

(i.) Smicra dnnsa, Walker.— On July 8th, 1892, Prof. C. H. T. 

 Townsend collected some specimens of a Smicra in the Grand Canon, 

 Arizona; and on July 27th he obtained what is doubtless a. $ oi the 

 same species, at the Zuni River, Arizona. These had remained in our 

 collection unnamed, until Miss MacGilmore, a student in zoology, worked 

 them over, and concluded they were probably Walker's divisa. I hardly 

 agreed with this, rather thinking the insect was new, but Mr. Ashmead 

 has now seen a specimen, and declares it is really divisa. The type 

 locality of 6'. divisa is Orizaba, Mexico, and no other specimens than 

 Walker's were known to Mr. Cameron when writing the Chalcididae of 

 Biol. Cent. Am. The Grand Canon specimens differ from Walker's short 

 description in the scutellum having two yellow spots, not a yellow hind 

 border. The teeth on the hind femora deserve some comment. Walker 

 says : " One large and several small teeth." Cameron places the species 

 in his section B.: " Femoral teeth small, minute, more than eight in 

 number." Our insect has one large and six small teeth, and so could not 

 be divisa if Cameron were correct ; but the little that Walker says accords 

 with our species, and would place it in Cameron's section A. 



(2.) Philanthus muiiijiiaculatus, Cameron.— One on Chilopsis in 

 Mr. Barker's garden, at Las Cruces, N. M., June 5th, 1894. A pretty 

 and distinct species, easily recognized by Cameron's figure and descrip- 

 tion in the Biol. Cent. Amer. The type locality is Atoyac, in Vera Cruz, 



Mexico. 



(3.) Crabro centralis, Cameron. — On Soianum elceagnifolium in 

 open ground behind the Central Hotel, in Las Cruces, N. M., June loth, 

 1894 (Ckll., 887). This was identified for me by Mr. Fox, and will be 

 included in his forthcoming memoir on N. A. Crabronidse. I mention it 

 now only to call attention to the curious fact that it also originally came 

 from Atoyac, in Vera Cruz, being, however, also found in Guatemala and 

 Panama.
