liitei Ckll. August, a female. (Det. by T. D. A. Cockerell, who 

 wrote about it as follows: "Described as M. martini hitei from 

 a single example taken at Pueblo, Colo., and this is the second 

 known. As the characters exactly agree, and the insect is now 

 shown to have a wide range, I doubt not that it is a good species. 

 There are others much like it in Texas, but they have some 

 black hairs on the thorax above, and differ otherwise. I wish 

 you could find out something about the habits of this species, 

 and if possible discover the male.")

 types, which I examined in Mus. Comp. Zoology.") 



Megachile brevis Say. July, a female specimen. (Det. by T. D. A. 

 Cockerell.) 

 kallstrcemi-ae Ckll. October, a female specimen. (Det. by T. D. A. 

 Cockerell, who remarked as follows: "A/, kallstrcemiie and val- 

 lorufii are characteristic arid-region bees. According to V. 

 Bailey's map. Piano is in the humid part of Texas. Some inter- 

 esting work might be done on the transition from the arid to 

 the humid belts, as shown by the bees.") 

 sexdentafa Robt. August. (Det. by T. D. A. Cockerell, who offered 

 the following remarks : "This is close to M. prunirut Sm. and has
