is sometimes quite dull, sometimes sliinj. The face is but 

 spavselj liaiiy. Head very broad on vertex. Protlioracic 

 spine well formed. Mesothorax very coarsely and densely 

 punctured, so as to be cancellate; median smoother shiny 

 area not much developed. Tegulai dark vandykc-browa. 

 Wings smoky, nervures and stigma black. Pleura very 

 densely punctured, so as to be cancellate. Abdomen with 

 white hair-bands at base of second and apex of second and 

 following segments, all largely rubbed off in my specimens. 



Ilah. Mescalero Indian Reservation, Sacramento Mountains, 

 N. M., a short distance below the Agency, rather common at 

 flowers of Bigelovia graveolens, var. glabrata, Oct. 2, 1896. 



This is certainly very near to armatay but the slightly 

 larger average size, dark flagellum, smoky wings, and very 

 densely punctured mesothorax may be taken as valid specific 

 characters. 



(6) Tegulae rufo-testaceous, punctuation not so close ; wings perfectly 

 clear ; flagellum brown beneath ; stigma rufo-f uscous. 



Colletes armata, Patten, 1879. 



One female, Las Cruces, N. M., late summer or early

 that what Cresson took for incequoh's was really armata. I 

 have the real inceqiialis from Illinois [Robertson)] it is larger, 

 with dark tegulge and other differences. In several respects 

 (wings, antennae, tegula?) it is more like higelovice^ but it has 

 the mesothorax shiny, with the punctures separate though 

 close, very different from Mgelovice. 



B. Males as large or larger than inffiqualis, xvWi lilaclc hairs on 

 dorsum of thorax and very large punctures on abdomen. 



Colletes gilensisj sp. n.
