Hab.—Mexico (F. Smith’s collection, 79-22). Brit. Mu- 
seum. This is the first Hypanthidiwm north of Panama. I 
was at first inclined to think that it might be the undescribed 
male of Anthidium bivittatum Cresson, but I believe bivittatum 
is a Dianthidium, and the differences indicated on comparison 
with Cresson’s description can hardly be all due to sex. H. 
aureocinctum is not very closely related to its South American 
relatives, but it is seen on comparison to be of the same gen- 
eral type as H. flavomarginatum (Smith). In Friese’s table 
(Das Tierreich) is runs nearest to Dianthidium apicale, from 
which it differs in many details. 
Panurginus cressoniellus calochorti Cockerell. 
Giipple Creek, Colorado, July 27 and 31,2 9,5¢é (S. A. 
Rohwer). Both sexes at flowers of Potentilla: males also at 
Pentstemon and Geranium. The male does not differ from 
that of typical cressoniellus. The altitude of the locality is 
9590 ft. A study of a series of New Mexico females of cres- 
soniellus indicates that calocharti is not more than a variety, 
certainly not a subspecies. Specimens from Beulah, August 18 
(W. Porter), hill above Beulah, August 19 (W. Porter), 
Harvey’s Ranch, August 22 (Porter and Ckil.), and Viveash 
Ranch, gooo ft., July 21 (Ckil.), all have dark antennz and 
belong with calochorti. Specimens from west of Beulah, 
August 23 (W. Porter) and top of Las Vegas Range, June 
29 (Ckil.) have the flagellum red beneath. Thus there is no 
evident relation between altitude and the color of the antenne. 
Sometimes the first r. n. enters the basal corner of the second 
s. m. 
Panurginus verus Cockerell. 
Upon comparison of the female types, it is seen that this is 
very close to P. cressoniellus calochorti. Aside from the dif- 
ference in the recurrent nervure, P. verus has the deeper mar- 
ginal cell rounded instead of angled at its upper apical corner, 
and the second abdominal segment (exclusive of the apical de- 
pression) more closely and evidently punctured. The last char- 
acter is a variable one in cressoniellus. I incline to the opinion
