60 AMERICAN COLEOPTERA. 



C dellisceiiS n. sp.— Form rather strongly elongate, though less so than 

 ill longiilus. Surface densely clothed with broadly overlapping scales, which are 

 whitisli and dark brown, and so confusedly intermingled that there is no dis- 

 tinct elytral pattern ; alternate interspaces of elytra a little more prominent, the 

 scales forming a distinct crest at the middle of the third and more posteriorly on 

 the fifth. Antennse blackish, the first and second funicular joints subequal, the 

 second barely as long as the next two united. Beak highly polished and sparsely 

 punctate beyond the antennal fovea, the punctures becoming gradually very fine 

 and remote apically. Eyes narrowly separated, the interocular space narrowest 

 at or below the middle, where it is about one-fifth or one-sixth the greatest width 

 of the eye. Prothorax wider than long, widest before the base, sides broadly 

 rounded posteriorly and broadly sinuate in front; the white scales condensed in 

 two small lateral bjtsal spots and in a large subrhomboidal discal spot which ex- 

 tends from the base to the apical constriction. Elytra twice as long as the pro- 

 thorax, humeri oblique, not prominent, sides subparallel to the apical umbones, 

 tips separately conically produced, leaving a well defined reentrant sutural 

 angle ; white scales vaguely condensed at the sides of the disk at anterior third, 

 and in a posterior series of small spots on alternate inteispaces. Beneath whitish 

 and paler brown, the latter scales often with violaceous lustre. Length 2.5-2.7 

 ram. ; width very nearly 1 mm. 



California (Pacific Grove). 



Described from a series of four specimens taken by Dr. Fenyes, 

 to whom I am indebted for the type. The species is peculiar among 

 those known to me in its dehiscent elytral apices, and is the only 

 one thus far known in our fauna outside the mammillatus group, in 

 which the elytral interspaces are cristate. The species might for 

 this reason best immediately follow the maimnillatus group. If we 

 regard bodily form and contiguity of eyes as of more importance, it 

 must be placed near longwus and allies, and in this case would best 

 stand at the end of tlie series. 



C. centrO|»ictU!>> n.sp. — Elongate-oblong, densely clothed with broad over- 

 lapping scales of pale and dark brown and white. Antennae brownish testaceous, 

 scape, first joint of funicle, and club darker; joints proportioned as in adspersus. 

 Beak rufopiceous, punctuation rather coarse and close, becoming finer and sparse 

 at apex, interocular space equal to half the wfdth of the eye, the point of closest 

 approximation slightly above the middle. Prothorax scarcely visibly wider than 

 long, sides parallel, distinctly sinuate at middle, rounding in a little at base, the 

 apical constrictions rather strong; disk trivittate with white, the intervening 

 areas marmorate with pale and dark brown, the former predominating. Elytra 

 slightly wider than and very nearly twice as long as the prothorax. Scales in 

 great part pale brown, the sutural interval in basal three-fourths, the second in 

 its middle third and a small spot adjacent to these posteriorly on the third and 

 fourth intervals white; white sutural area narrowly almost completely margined 

 with blackish brown. There are two lateral white spots, one subhumeral, the 

 other near the middle, and alternating with these two blackish spots. Scales 

 l)eneath white and pale brown, confusedly intermingled. Length 3.9.; width 

 1.5 mm.
