542 M\bs G. Ricardo on new Species of 



resemblance to Megachile frvgalis, Cresson, which, however, 

 has long spines on the anterior coxae, though these ai'e not 

 mentioned by Cresson. 



A male of C. pratti was taken by Mr. J. C. Crawford at 

 CotuUa, Texas, May 11, 1906, at flowers of Parkinsonia. 

 Three females, two from Cotulla (March 27, 1908, Jones and 

 Pratt ; May 5, 1905, Craivford) and one from San Diego 

 (March 25, 1908, at Howers of Marrubhim vulgare^ collected 

 by Jones and Pratt) can only belong to C. pratti. They 

 have the following special characters : — Clypeus very deeply 

 incised or emarginate, the incision bounded by large, shining, 

 pointed teeth directed outward ; upper part of clypeus with 

 a prominence ; flagellum bright ferruginous beneath except 

 at base ; labrum long, truncate at apex, with a prominent 

 tubercle some distance from apex, bearing orange hairs 

 directed upwards; mandibles long and stout, Avith three 

 short teeth at apex ; wings a little dusky (brownish) ; the 

 erect pale hair of mesothorax not mixed with black ; venti'al 

 scopa entirely wdiite, with a faint yellowish tint There is a 

 strong superficial resemblance to the female of Megachile 

 Occident alls, Fox. 



Chelostomoides appears to be related to the Australian 

 Heriadiform group of Megachile.
