Head, body, and legs deep Prussian-blue ; wings clear but 

 hairy, nervures and stigma black. Antennae entirely black, 

 minutely pubescent, 44-jointed ; palpi, except first joint, 

 whitish. Cream-coloured markings as follows : — a round 

 spot on each side of clypeus ; a broad baud, narrowed to a 

 point above, along the lower inner orbital margin ; a narrow

Ilab. Side canon north of Ruidoso, N. M., about 6800 feet, 

 July 22, 1898, at a patch of Verbascum thapsus (C. H. T. 

 Toivnsend) . 



Related to I. cceruleus, Cresson, of which it may possibly 

 be a variety, but it presents several differences, and is pre- 

 sumably a valid species. 



Hylotoma humeralis, P. de Beauv., 1797.

 at flowers of Cicuta occidentalis.

 tibiae are sometimes all black ; the costa is black, not 

 yellowish ; the wings vary in smokiness.
