SOME INSECTS OF THE HUUSONIAN ZONE IN NEW MEXICO.— III. 



HYMENOPTERA APOIDEA. 



BY T. D. .\. COCKERELL. 



Bombus proximus Cresson. 



Abundant. 



B. proximus var. Inmhirdi (Cress.) 



A few flying with the typical form. 



B. ternarius Say. 



1?. 



B. juxtus Cress. 



B. frigidus Smith. 



I 9 . New to New Mexico. Origi- 

 nally described from "Arctic America ; 

 Hudson's Bay." It is also known from 

 Great Slave Lake, Yukon River, Van- 

 couver I., and the high mountains of 

 Colorado. It ha:; the closest possible 

 resemblance to B. derhamcUiis Kirby, 

 which I have from Innsbruck in the 

 Tirol, collected by Mr. Friese. I be- 

 lieve that the B. dcrhatnelhis reported 

 by Kirby from Arctic America (Lat. 

 65°) must have been frigidus. When 

 in Philadelphia last year I saw Cresson's 

 types of B. puinami and couperi^ and it 

 seems to be an open question whether 

 they are really separate from one an- 

 other and from frigidus ; but it will be 

 necessary to make a careful study of 

 more abundant material than has yet 

 been available, to precisely fix the sta- 

 tus of these forms. 



Megachile wootoni Ckll. 



1 (J . Belongs to a circumpolar 

 group, Megachile, s. str. 



Halictoides (Parahalictoides) 

 maurus (Cresson). 



I $ . New to New Mexico. 

 Panurginus bakeri (Ckll.). 



1 $ at flowers of Potcutilla [Dasi- 

 phora) frntifosa. New to New Mexico. 



P. cressoniellus Ckll. 



2 9 , one at flowers of J'otentilla frii- 

 ticosa. 



P. verus, n. sp. 



I 9. Length 8 nun., entirch' sliinincr 

 black, even to the tarsi and riayelliini ; liead, 

 thorax, legs and ape.^c of abdomen with 

 ratlier long white liair, that on llie bind legs 

 carrying some orange pollen ; aniennae 

 leaching the tegulae ; face and clypeus with 

 large sparse punctures; front minutelv stii- 

 ated. with small close punctures ; mesothorax 

 closelv punctured at the sides, sparsely in the 

 middle ; first segment of abdomen shining, 

 with minute sparse punctures; following 

 segments minutelv sculptured, with closer 

 small punctures ; tegulae shining piceous ; 

 wings slightly dusky, stigma and nervures 

 black; marginal cell broadly oblii/iiely trun- 

 cate at the t'«(/, appendiculate ; first submar- 

 ginal cell more than twice as large as second ; 

 fir^t recurrent }icrvure joiuing first siibmar- 

 gitial cell -veil before its eud ; second reciu"- 

 renl joining second submarginal coll just 

 before its eiul. 



This is a very interesting species, 

 being a true J'aiiurgi/ius of the type pre- 

 dominant in Europe and Asia. It ap- 

 parently conies nearest to P. pundiveii- 

 tris and /'. altii-ola from the Caucasus, 

 and r. moiilniius from the Alps. I have 

 before me a specimen of P. moiitanus 

 collected by Mr. P'riese at Innsbruck,
