316 THE CANADIAN ENTOMOLOGIST. 



Pachybrachyi /wis, nov. sp. — Small, or medium sized, cylindrical, 

 semi-shining dirty-yellow, punctate striate, more or less clouded with brown 

 on the standard spots, the shield well marked as a long smooth area. 

 Length, 2-2^ mm. 



Head yellow, convex, punctured, with dark, finely impressed median 

 line and vertex, eyes distant in both sexes, antennie red, growing dark to- 

 wards the tip and reaching the second segment of abdomen in J , shorter 

 in V ; thorax narrowed in front, yellow, moderately and finely brown 

 punctate, transverse impression moderate, M more or less indicated by 

 brown clouds, lateral edge subangulate ; elytra yellow, with striae of brown 

 punctures diffused in the scutellar area and broken in the sixth, seventh 

 or eighth intervals back of the humerus ; this break is sometimes quite 

 slight; the o* ' s arc much more inclined to regularity than the $ 's, 

 especially in the punctuation of the scutellar area, which in one example 

 is almost regular, the elytral shield is shown as an elongate smooth raised 

 third interval, running from about the middle down over the edge of the 

 convexity. This is at times supplemented by a similar, though smaller 

 space in the fourth interval. Some of the standard spots show at times as 

 little splashes of brown, marginal stria lightly curved and sinuate behind, 

 lobe well developed, with a small row of marginal punctures ; body be- 

 neath black, with the epimera, sides of abdomen, last segment and 

 pygidium yellow, legs yellow, with reddish clouds, fossa shallow, dull and 



triangular. 



Three £ 's, 2 9 's, Colorado Springs, Colorado. Type coll., Bow- 

 ditch. 



I also place here examples from Durango, Colorado ; Taos County 

 and Coolidge, New Mexico; Winslow, Arizona, and Reno, Nevada. They 

 differ slightly, but all have the prominent smooth space on the third 

 interval. The Coolidge, N. M., specimen has a well-marked M and 

 thickly-punctate thorax. 



PacJiybrachys Texanus, nov. sp. — Very close to eburifer, Suff., and 

 nebulosus, Suff., but readily separated by the nearly approximate eyes of 

 the o* ; general colour yellow, with brown or livid markings. Head flat, 

 closely punctured with livid central line and vertex, eyes of $ just visibly 

 wider apart than the width of the livid central mark, those of the 9 a 

 little wider, about the same width as in J of similis, nov. sp.; antennpe 

 yellow at base, growing darker towards the tip, reaching about the middle 

 of the body in $ , not as long in ? ; thorax very finely brown-punctured, a 

 little narrowed in front, sides in J; almost straight, ? just visibly sub-
