among the bases of the young leaves. When approaching 

 maturity it is a trifle over half an inch in length, of a creamy 

 colour, with pure white hairs of an equal length with the dia- 

 meter of the body, and its head is slightly tinged with brown. 



At this time, about the beginning of June, the larvae were 

 apparently feeding, or lying dormant, preparing for the pupal 

 change, on the under side of the leaves, and in the heart of the 

 plant. Each larva formed a wool-like nidus, wherein it ulti- 

 mately pupated about the end of June. The imagines emerged 

 about the end of July. 



There was no difference in the appearance of these bred 

 moths and the newly caught wild specimens.

 1105 [J., second 1428, the second measured to beginning of third joint, 

 not counting the hyaline process (170 /x) extending beyond; meso- 

 thorax shining, with the strong punctures well separated ; scutellum

Hah. Mescalero, New Mexico, July 12, two females (C. M. 

 Barber). Named after the Mescalero Apaches, in whose territory 

 it is found. It is closely related to H. truncata, Cresson, and 

 H. samhuci, Titus, but separated by the dark wings, the colour 

 of the spurs, and the measurements of the palpi. H. adunca of 

 Europe, the type of Hoplitis, has the tongue much longer, the 

 first joint of labial palpi much shorter in proportion to second, 

 and the blade of maxilla not so slender.
