DELIPHRUM Erichs. 



The two following species are referred to Deliphrum, although 

 in some characters they appear to be intermediate between that 

 genus and Lathrimteura. In sequicolle the intermediate tibiae only 

 are sparsely spinulose, the others coarsely setose, or with spines 

 only very slightly thicker than the ordinary seta3 ; in occiduum the 

 spinules of the hind tibiae are but slightly more visible. A few very 

 short spines are also visible along the intermediate tibiae of Lathri- 

 mseum spretum. In the general facies and fine even punctures of 

 the pronotum both of these species agree very satisfactorily with 

 Deliphrum tectum Payk. ; they are very much smaller than D. ex- 

 p)ansum Lee. from Colorado. 



The antennal differences given by LeConte and Horn (Class. Col. 

 N. A.) to distinguish Lathrimseum and Deliphrum do not exist, 

 these organs being equally incrassate in both ; they are however 

 longer and much more nearly filiform in Olophrum. In Lath, sub- 

 costatum the tibiae are not spinose, but evenly covered with short 

 stiff inclined setae. 



D. sequicolle n. sp. — Broad, polished, glabrous, dark piceous-browii, 

 the head and abdomen blackish ; antennae black, slightly pale at base ; legs, 

 sterna and epipleurse paler, flavescent. Head transverse, three-fifths as wide 

 as the prothorax, very finely, remotely pnnctate, smooth ; ocelli large, promi- 

 nent, distant by two-fifths the width ; dorsal constriction of the neck obso- 

 lete ; surface feebly impressed before each ocellus and at the sides of the 

 clypeus ; lateral margins of the latter deeply interrupted as usual before the 

 eyes for the reflexion of the antennae ; eyes moderate ; antennae two-fifths as 

 long as the body, slender toward base but rapidly though gradually, strongly 

 incrassate near the apex, sixth joint one-third longer than wide, eighth and 

 tenth similar in form, slightly wider than long, the tenth very much the 

 larger. Prothorax not quite twice as wide as long, the sides parallel, evenly, 

 moderately rounded ; basal angles obtuse and blunt ; disk minutely, not very 

 densely, evenly punctate, the punctures rather closer and stronger near the 

 base, the surface narrowly explanate along the sides, not at all impressed in 

 the middle, the sublateral fovese before the middle very feeble. Elytra sub- 

 quadrate, nearly parallel, truncate at apex, not as long as wide, not more than 

 twice as long as the prothorax ; sides nearly straight ; humeri not exposed at 

 base ; disk coarsely deeply confusedly and not very densely punctate, the 

 punctures having only the most indistinct lineate arrangement, altogether 

 confused and denser near the suture. Abdomen with more than three exposed 

 segments, subimpunctate, polished. Length 2.0 mm. ; width 1.1 mm.
