shorter, so that it is conspicuously broader ilian long ; flagellum dark, 

 with only a faint red tinge beneath ; hair on outer side of basal joint of 

 middle tarsi brownish-black (rufo-fulvous in Comanche). From M. helian- 

 t/ielli, Ckll., it differs in the colour of the hair on the hind tarsi and apex 

 of abdomen, etc. 



Ifab. — Fedor, Texas {Birkmann). This may be a race of AI. 

 Comanche, but in the absence'of intermediates I leave it as a species. It 

 runs in my tables next to M. Coloradeftsis, Cress,, from which it is easily 

 known by its larger size and other characters. 



Mr. Birkmann also took at Fedor M. atripes, Cr. (fune 8), M. obliqua, 

 Say (May 29), and M. hit or t a, Cr. 



Entechnia fulvifrons (Smith ) . 

 Fedor, in August. The bees of this genus seem quite unable to fold 

 away their long mouth-parts; they always carry them, when at rest, under- 

 neath the body, like the beak of an hemipteron. The present species 

 extends to the Argentine and Bolivia, whence it was described by Schrottky 

 as Meliphila ipomoece. 



Xenoglossodes eriocarpi (Ckll.). 

 Fedor, June 11. New to Texas. X. albata (Cr.) was also taken at 

 Fedor, June 22. 



Anthophora Texana, Cresson. 



Fedor, the ^ jLme 12, the ? June 17. The ^ (hitherto unknown) 



has the face-marks bright yellow, and is in all respects (including the 



armature of the hind legs) extremely close to A. CalJfor?iica, Cr. The 



hair of the thorax above is pale echreous, and is without the intermixture 



of black seen in the ? . A. tarsata stibtarsaia, Ckll, is also very closely 

 allied, but is readily distinguishable from Texa?ia, in the female by the 

 rapid narrowing of the face below, and in the male by the admixture of 

 black hair on the thorax above. All these insects have the same peculiar 

 structure of the hind legs, and are evidently local representatives of a 

 single wide-spread type. Whether we call them species or subspecies 

 will depend upon the existence or otherwise of intergrading forms in 

 localities not yet explored. A ? having the characters of Texana has 

 been taken by Snow in Arizona.
