COLEOPTERA. 129 



This very fine species should evidently be placed immediately after 

 tumiditm in Dr. LeConte's table of the genus Cryptobium. The very 

 large elongated head, distinctly widest behind the eyes, very long 

 slender antennae and pale coloi", separate it from other forms in this 

 neighborhood. 



C. COllvergens n. sp. — Form rather slender, rather feebly convex ; 

 sides parallel ; head and prothorax piceous-black ; elytra dark rufo-piceous ; 

 abdomen nearly piceous-black, slightly paler and more rufous toward tip ; 

 pubescence rather long, coarse, erect and bristling over the entire body, 

 somewhat abundant and nearly evenly distributed, pale fulvous. Head 

 moderate in size, much longer than wide; eyes rather small but convex and 

 prominent; sides continuous in outline with them behind, distinctly conver- 

 gent toward the neck which is not two-thirds as wide as the width at the 

 eyes, nearly straight toward the eyes, more arcuate behind ; just in advance 

 of the eyes the head is scarcely three-fourths as wide as across the latter, 

 forming a short very transverse epistoma the sides of which to the antennae 

 are feebly convergent and straight, transversely truncate anteriorly ; supra- 

 antennal tuberculations very strong and conspicuous, front between tliem 

 sparsely and irregularly punctate, shining, minutely granulose ; occiput 

 coarsely and evenly punctate, moderately convex, polished, minutely and 

 feebly strigato-retieulate ; punctures round, separated by less than twice 

 their widths in the middle, becoming much more dense finer and very con- 

 fused behind the eyes where there is on each side two large areolate punc- 

 tures bearing long erect setae ; between them extending longitudinally from 

 the eye there is a broadly rounded feeble ridge ; under surface miniitely ^- 

 ticulated, rather finely sparsely and evenly punctate, not elevated along tlie 

 gular suture ; maxillary palpi rather long and slender, second joint slender, 

 slightly ilattened and feebly bent, equal in length to the third which is 

 slender, conical, feebly narrowed toward base, truncate at tip, nearly four 

 times as long as wide, fourth joint very small, subulate, conical, much nar- 

 rower than the apex of the third and received partially within it, but slightly 

 more than one-fourth as long as the latter; antennae rather slender, very 

 feebly incrassate, longer than the head, very dark rufous, basal joint feebly 

 sigmoid, scarcely longer than the next three together, second much shorter 

 than the third and very slightly longer than the fourth, the latter scarcely 

 more than two-thirds as long as the third, first two joints glabrous and 

 sparsely setose, the remainder very finely pubescent throughout and sparsely 

 setose. Pro'horax very small, scarcely more than three-fourths as long or 

 wide as the head ; sides parallel and feebly arcuate ; apical angles acutely 

 rounded, basal rather strongly and evenly so ; base broadly and very feebly 

 arcuate; apex broadly sinuate ; disk broadly convex, about one-fourth longer 

 than wide, rather coarsely closely and unevenly punctate ; broad median 

 line impunotate, punctures more sparse toward the base. Elytra at base 

 distinctly wider than the pronotum, slightly narrower than the head ; sides 

 parallel and nearly straight ; together broadly roundly and moderately 

 sinuate behind ; apical angles evenly rounded ; disk very broadly and 

 feebly convex, distinctly longer than the pronotum, more than one-fourth
