388 SUP.FAMILY x. CURCULIONIX^. 



without more definite locality, but probably part of Casey's co- 

 t^pes, of which more than one hundred specimens came from In- 

 diana and Illinois. Known also from Iowa and southwestern 

 Pennsylvania, where it was taken by Hamilton on joe-pye weed, 

 Eupatorium purpureum L. Casey gives the color as "dark 

 piceous," but the elytra in all specimens at hand are distinctly 

 reddish, some of them with a narrow, piceous sutural line. 



Centrinopus alternatus Casey, (1892, 602) differs only in having the 

 pale scales of thorax more condensed on sides and median line, with 

 the intervening scales slightly darker, the three vittse, therefore more 

 distinct; those on elytral intervals 3, 5, and 7 also more dense, giving 

 the elytra a distinctly striped appearance. The Maryland specimen 

 mentioned by Casey as being in the Julich collection is at hand, and 

 there is no appreciable difference between it and helvinus except that of 

 the distribution of pubescence. We therefore regard it as only a nominal 

 variety of the latter. 



XVI. PACHYBARIS Lee., 1876. (Gr., "thick" + Baris.) 



Short, robust, almost glabrous species having the beak slender, 

 strongly curved, as long as head and thorax, female, striate. the 

 punctures above arranged in rows ; antenna? inserted far behind 

 its middle, their grooves beginning near tip of beak, running 

 obliquely downward and almost confluent on the under side; 

 scutellum flat, almost circular; prosternum flat, broad between 

 the coxa? with two deep foveaB connected in front by a groove. 



590 (8909). PACHYBARIS POROSA Lee., 1876, 302. 



Broadly oval, robust, convex. Black, polished; beak, legs and an- 

 tennse dark reddish-brown. First joint of funicle as long as the next 

 four united. Thorax short, two-thirds wider than long, sides parallel on 

 basal third, then broadly rounded and feebly constricted to apex; disc 

 very convex, finely alutaceous, coarsely, deeply and rather sparsely 

 punctate. Elytra about as long as wide, scarcely wider and three-fourths 

 longer than thorax, narrowing from the rather prominent humeri to 

 apex; striae wide, deep, feebly punctate; intervals flat, each with a row 

 of large, close-set punctures, bearing very short, prostrate brownish

 whitish hair. Length 3.6 4 mm.

XVII. MICROCHOLUS Lee., 1870.
