Described from 20 specimens (1 male type). Fifteen specimens 

 reared from bamboo (Arundinaria long if olid) in storage at Hoboken, 

 N. J., shipped from Mexico; three specimens intercepted at Laredo, 

 Tex., in bamboo poles from Mexico; and two specimens intercepted 

 at Nogales, Ariz., in bamboo from Mexco. 



This species is allied to Micrapate brasiliensis (Lesne) , but differs 

 from that species in having the clypeus and front of the head clothed 

 with long, semierect hairs, the clypeus broadly and shallowly emar- 

 ginate in front, the clypeal suture not distinct, the pronotum quadrate 

 and not wider than long, and the upper surface of the body clothed 

 with distinct hairs.

Male. — Brownish black to black, sometimes with base of elytra and 

 abdomen in part reddish, the antennae, palpi, labrum, and tarsi yel- 

 lowish or reddish brown. 



Head very densely, finely punctate or rugose, with long, longitudi- 

 nal, parallel costae on occiput, and nearly glabrous on clypeus and 

 front of head ; clypeus deeply, arcuately emarginate in front ; clypeal 

 suture distinct at middle, obsolete at sides; labrum very finely, 

 sparsely punctate. 



Pronotum slightly wider than long, widest behind middle, shal- 

 lowly emarginate in front; sides broadly rounded, more strongly 

 converging anteriorly, with a small, broad tooth at apical angles; 

 posterior angles broadly rounded; surface nearly glabrous, coarsely, 

 densely punctate on basal half, the punctures sparser toward sides, 

 densely, irregularly dentate on apical half, the teeth broad, semi- 

 erect, variable in size, and rasplike. 



Elytra at base slightly narrower than pronotum behind middle; 

 sides nearly parallel, conjointly broadly rounded at apices; apical 

 contour (when viewed from above) broadly rounded; surface gla- 

 brous, densely, coarsely, confluently punctate over entire surface; 

 apical declivity arcuately deflexed, and not depressed along sutural 

 margins; sutural margins on apical declivity not gibbose or expanded 

 laterally at middle, but narrowly, uniformly elevated along entire 

 length, the sides not abruptly deflexed. 



Abdomen beneath coarsely, densely punctate, smooth between punc- 

 tures, sparsely clothed with rather short, recumbent, whitish hairs; 

 last visible sternite broadly rounded at apex. Posterior tibiae with 

 erect hairs on outer surface. Posterior tarsi with long, fine hairs. 



Female. — Differs from the male in having the last visible abdominal 

 sternite broadly rounded at the apex, with a small, round fovea, which 

 is feebly, longitudinally carinate posteriorly. 



Length 4-5.5 mm., width 2-2.2 mm. 



Type locality. — Brazil, various localities in the States of Bahia, 

 Minas Geraes, and Sao Paulo; types scattered in various collections 

 and museums. 



Distribution. — Recorded only from southern Brazil. Two speci- 

 mens were intercepted at New York, March 11, 1925, in dried tree roots.
