488 Coleopterological Notices, IV. 



convergent from the base to apical third, then abruptly rounded and 

 rather prominent, thence very strongly convergent to the apex, the 

 latter much less than one-half as wide as the base ; disk very con- 

 vex, coarsely, deeply punctate, the edges of the punctures obtuse ; 

 median impunctate line often obsolete but frequently distinct. 

 Elytra about equal in width to the prothorax, the humeri slightly 

 prominent ; sides subparallel, the apex broadly obtuse ; striae very 

 coarse, deep ; intervals alternately wide and rather narrow, the 

 punctures coarse, close, subrugose, confused on the wider intervals. 

 Prosternum broadly impressed along the middle, separating the 

 coxae by a little more than one-half of their own width. Length 

 3.5-4.8 mm.; width 1.8-2.3 mm. 



New York, Indiana, Iowa, Missouri, Colorado and Texas. A 

 widely distributed, common and easily recognizable species. I think 

 that there is but little doubt that Say described transversa from 

 one of the numerous sculptural modifications of inter stitialis, but 

 as the species is more commonly known under the name transversa 

 and since the name " inter stitialis 11 refers to a form which has never 

 been accurately defined, and has always given rise to confusion and 

 uncertainty, even on the part of Say himself, the course here pur- 

 sued would appear to be for the best interests of science. Carinu- 

 lata is not tenable as a species, the smooth median line of the 

 pronotum being a most variable feature, as is also the interstitial 

 punctuation. 



19 Bar is dilatata n. sp. — Oval to oblong-oval, robust, strongly convex, 

 black, the beak rufescent toward apex, the legs bright rufous ; integuments 

 rather shining, without trace of aeneous lustre. Head obsoletely, the beak 

 moderately densely, deeply punctate, the latter short, robust, strongly arcuate 

 toward hase, less than one-half {% ) to nearly two-thirds ( $ ) as long as the 

 prothorax ; antennae moderate. Prothorax large, convex, scarcely one-fourth 

 wider than long; sides feebly convergent and just visibly arcuate to apical 

 fourth, then rather strongly rounded but not very prominent, thence strongly 

 convergent and straight or just visibly sinuate to the apex ; base three and 

 one-half times as wide as the head, transverse, straight, the median lobe 

 rather wide and strongly developed, rounded ; disk with narrow, more or less 

 imperfect median line, the punctures deep, rather coarse, a little more than 

 one-half as wide as the scutellum and generally separated by about their own 

 widths. Scutellum moderate, often moderately impressed in the middle toward 

 the posterior margin. Elytra one-fourth to one-third longer than wide, about 

 two-thirds longer than the prothorax, and, at the moderately tumid humeri, 

 quite distinctly wider than the latter ; sides subparallel or very feebly con- 

 vergent ; apex broadly, rather abruptly rounded; disk with somewhat fine
