272 ENTOMOLOGICAL NEWS. [Oct., 'oi 



appearance of a very broad black band between the wings ; tegulae 

 black; wings light fuliginous (about as dark as in B. borealis ; not 

 nearly so dark as in B. sonorus) ; legs with black pubescence, that on 

 inner side of basal joint of hind tarsi very dark reddish ; abdomen with 

 the hair on the first four segments dorsally light ochreous, suffused with 

 red at sides of second and third, the red being of exactly the same tint 

 as that which covers the abdomen of B. lateralis Sm. ; hair of last two 

 segments entirely black ; of venter sparse and black, with whitish hairs 

 about the middle. 



Hab. — Boulder, Colorado, June 10, 1Q05 ( W. P. Cocker ell'). 

 Allied to B. fervidus, but easily distinguished by the light 

 hair of face, the smaller and less numerous punctures of cly- 

 peus, etc.; from B. vioiiardce it is known by its larger size, 

 wholly black hair of hind femora, black hair of metathorax, 

 etc. ; from B. borealis by the light hair on pleura. By the red 

 at sides of abdominal segments it approaches B. vancouverensis. 



Anthophora curta Provancher. 



Two males taken by Mr. S. A. Johnson at Alamosa, Colo- 

 rado, August 6, 1903, at flowers of Cleome {i. e., Peritovid) 

 differ so much that they may represent different species. One 

 is more robust, and has black hairs on the vertex and meso- 

 thorax, as in the female ; the other is more slender, the abdo- 

 men especially being less robust, and the head and thorax are 

 without black hairs. Supposing that the one with black hairs 

 is to be considered typical, the one*without them may for the 

 present be termed var. peritomcs. This var. peritomce is easily 

 known from male flexipes and albata by the normal middle 

 tarsi, and from macidifrons by the white pubescence, darker 

 tarsi, wholly black antennae, etc. 



Var, peritomcE appears to be common in New Mexico. Males 

 before me are from Santa Fe, August 5, at flowers of Periionm 

 serrulatum ; Mesilla, September 4, at flowers of Isocoma 

 wrightii ; Las Cruces, August 24, at flowers of Solidago cana- 

 densis ; L,as Cruces, August 26. The size is quite variable. 



Since \h^ peritomce form appears to be more common than 

 the presumed typical male, it is an open question whether it 

 should not be considered the proper male of ctirta ; and the 

 other, notwithstanding its closer resemblance to the female, 

 the variety. This question will only be settled when we have 

 a good series of specimens from the original locality of curta.
