COLEOPTERA. 177 



The tarsal claw figured on the plate resembles in general outline 

 that of propinquus, but is much thicker and shorter, especially 

 toward the tip. 



22. A. piligllis n. sp. — Form very robust. Pubescence short, semi-erect, 

 evenly distributed, rather d-ense and moderately conspicuous, cinereous. 

 Head spiall, twice as wide as long; interocular surface very feebly convex, 

 two and one-half times as wide as the eye; sulcations very feeble; inter- 

 mediate surface broadly and evenly convex ; puncture* rather large, round, 

 deeply impressed, evenly distributed, very close but not coalescent . : inter- 

 spaces nearly acute; ocular lines meeting at more than two lengths in 

 advance; antennae rather short and robust, as long as the width of head, 

 basal joint black, remainder pale testaceous, club very slightly darker, not 

 prominent ; third joint one-half longer than the fourth, seventh much longer 

 than the eighth, almost equal in thickness, last two joints much wider and 

 longer than the ninth ; maxillary palpi rather long, testaceous, third joint 

 flattened, infuscate toward tip. Prothorax arcuately and very gradually in- 

 creasing in width to the middle, where it is distinctly narrower than long ; 

 sides thence moderately convergent posteriorly and just perceptibly sinuate : 

 anterior and posterior margins nearly equal in length and curvature, feebly 

 arcuate ; surface feebly swollen near each basal angle, evenly and very 

 closely punctate ; punctures deep, not coalescent, near the base almost poly- 

 gonally crowded, rather coarse. Elytra at base slightly wider than the head ; 

 sides very feebly divergent posteriorly, very feebly arcuate, longer than the 

 width at base; together broadly, somewhat angularly and rather strongly 

 emarginate behind ; suture more than one-third longer than the pronotum ; 

 surface feebly impressed along the suture, more broadly ho toward the base, 

 very closely and evenly punctate ; punctures round, very deep, rather coarse ; 

 interspaces very narrow. Abdominal segments decreasing uniformly and 

 rapidly in width, first slightly narrower than the contiguous elytra, nearly 

 cylindrical ; border obsolete except on the first segment, where it is rather 

 strong ; surface closely, deeply, and evenly punctate ; interspaces very nar- 

 row ; transverse carinae not cus-ped, unevenly undulated. Legs short and 

 slender, black, tarsi dark piceous-brown ; first joint of the posterior not as 

 long as the next two together, slightly shorter than the last ; third joints 

 much less strongly bilobed than the fourth. 



Male. — Third and fourth ventral segments just perceptibly modified in the 

 middle fourth at apex, being feebly flattened; fifth segment not modified, 

 posterior edge very minutely spongy ; sixth broadly incised at apex, incisure 

 occupying the entire apex, anterior angle rounded slightly, sides nearly 

 straight, fully three times as wide as deep ; seventh broadly rounded behind. 



"Female. — Sixth segment acutely rounded at the immediate apex, sides 

 theme slightly sinuate anteriorly; tip of the seventh segment truncate, 

 having a narrow emargination in the middle of the truncation. 



Length 4.0 mm.
