1 78 MEMOIRS ON THE COLEOPTERA 



developed and prominent, finely faceted as usual; punctures fine and 

 sparse; antennae rufous, of nearly the same structure as in Litargus; 

 prothorax three-fourths wider than the median length, convex, gradually 

 declivous toward the sides, very finely, not densely punctate; sides feebly 

 converging, evenly and rather strongly arcuate from base to apex, the 

 base arcuate, oblique laterally; elytra three times as long as the prothorax, 

 inflated posteriorly, widest behind the middle, together obliquely nar- 

 rowed behind, the individual tips narrowly obtuse; punctures notably 

 fine, well separated; under surface finely and closely punctate, the ab- 

 domen more finely; tarsi with the two inferior oblique lobes well developed. 

 Length 2.75 mm.; width 1.2 mm. California (Mokelumne Hill, Cala- 

 veras Co.), Blaisdell. 



Differs from grisescens in the much finer and sparser punctures 

 of the entire upper surface, more arcuate base of the prothorax, 

 posteriorly inflated elytra and absence of evident maculation of the 

 elytral pubescence. 



Byturus punctatus n. sp. Stout, oblong, parallel and convex, slightly 

 shining; pubescence long, coarse, abundant, bright fulvous in color and 

 conspicuous, including a lineal arrangement on the elytra; head three- 

 fifths as wide as the prothorax, not coarsely but deeply, somewhat closely 

 punctate, as usual without trace of epistomal suture, the eyes very large 

 and globose; antennas unusually short, scarcely longer than the head, the 

 club not longer than the preceding four joints, abruptly broad and 

 rather compact; prothorax very convex, not quite twice as wide as long, 

 broadly deplanate at the sides postero-laterally, rather strongly and 

 closely punctate, the sides subparallel and arcuate, the base very feebly 

 arcuate; scutellum as in the preceding; elytra as wide as the prothorax and 

 three and one-half times as long, three-fifths longer than wide, gradually 

 ogival apically; punctures very coarse, deep and close-set though evi- 

 dently separated; under surface with the pubescence whiter, closely 

 decumbent, very dense toward the sides of the post-sterna, on which the 

 punctures are very fine; they are larger but feeble on the abdomen; 

 tarsal lobes rather feebly developed. Length 3.6 mm.; width 1.5 mm. 

 District of Columbia. 



Differs widely from any of our other species in the very conspi- 

 cuous elytral punctures and in the long coarse fulvous pubescence; 

 from either of the European species it differs even more strikingly 

 in sculpture. The single example seems to be a female, but even 

 considering this, the abbreviated antennae, in conjunction with the 

 very large eyes, constitute a noteworthy character. At the middle 

 of the length and at outer fourth of each abdominal segment one 

 to four, there is a large impressed puncture. 



This species belongs to the same section of the genus as the 

 European fumatus, but the elytra are not only more coarsely punc-
