T. D. A. COCKER ELL. 109 



Hab. — Roswell, New Mexico, at flowers of Flaveria angndlfolia, 

 aiictt., end of Augnst or first of September (Cockerell). At the 

 same time and place, tlie Flaveria was also visited by the beautiful 

 Nomia nortoni Cresson. 



Melisso(le»$ iiigro!$ignala Ckll. 



My wife collected two specimens near San Ignacio, New Mexico, 

 August 15, 1899. These were unfortunately overlooked, and the 

 species was later described from material collected by Snow in 

 Arizona.

A new locality in Gibson, New Mexico, September 30th (Anna 

 Gohrman). 



iVIelissodes atripes Cresson, var. acouianche n. var. 



S . Like the male of atripes, but scutellum with much brown- 

 black hair, and hair of hind femora and tibiae dull reddish instead 

 of black ; that at apex of abdomen also more or less pallid. This 

 is a form of atripes in which the hair of the hind legs become pale and 

 reddened, while as if in compensation, dark hair appears on the scu- 

 tellum. Not unnaturally an eminent authority on bees had labelled 

 it M. covianche, but the lively ferruginous of the hair on the hind 

 legs of Comanche, especially that of tlie tarsi (which in acomauche 

 remain black), is entirely different, and the end of the apical plate 

 of the abdomen is broader in acomauche. From M. caliginom, 

 acomauche is easily known by the light reddish hair of the pleura, 

 that of caliginosa being black. There is no doubt that atripes and 

 comauche are closely allied, and it is possible that acomauche is a 

 hybrid between them. 



Hah. — Fedor, Texas, June 11, 1896 {Birkmann). 



Melissodes inelandri n. sp. 



9 . — Runs in my tables nearest to M. raphaelis, having, like it, 

 the hair of the pleura partly black and partly light. It is a species 

 of the stature and general appearance of M. communis Cress., from 

 which it differs as follows: Flagellnm darker; hair of occiput 

 black; hair of mesothorax all black, except a slight admixture of 

 greyish white along the extreme anterior margin, not easily noticed, 

 and a little tuft of whitish at the posterior corners; hair of pleuia
