Xylehorus wallacei, sp. n. 



Fem. Elongata, cyliudrica, picea vel badia, sat nitida, erecte 

 setosa ; prothorace subquadrato, dorsopost medium gibboso. postice 

 subasperate punctato ; elytris striato-puuctatis, interstitiis planis 

 per totum alternatim tuberculis piliferis et punctis uniseriatim 

 instructis, declivitate perobliqua, baud rotusa, infra marginata. 

 Long, y'5 mm. 



Female. Elongate, cylindrical, brigbt brown or piceous, rather 

 shining, with erect scattered long brown hairs. Head impressed 

 above the mouth on either side, with deep sparse piliferous 

 punctures and a median elevated line, mouth fringed ; eyes largo, 

 broad oval, emargiuate, encroaching on the front, antennae 

 testaceous. Prothorax subquadrate, not longer than broad, the sides 

 and apex separately and feebly rounded, the former slightly con- 

 tracted before the middle, the anterior angles broadly rounded, the 

 hind-angles subrectangular, the base subtrausverse ; dorsal gibbosity 

 post-median, rounded and not sharply defined, surface with 

 scanty pubescence at the sides, anteriorly convex, declivous and 

 asperate with small rugae, fine and close on the gibbosity, posteriorly 

 subopaque, with fine subasperate punctures, the median line 

 narrow. Scntellum small, rounded, convex, shining. Elytra as 

 wide as the prothorax and twice as long, truncate at base, the 

 shoulders obtuse, the sides parallel, somewhat narrowed towards 

 the rounded apex ; surface slightly rounded from the base to just 

 behind the middle, thence very obliquely declivous, striate-punctate, 

 the punctures rather large, shallow, the striae scarcely impressed, 

 the interstices shining, flat, with a single uniform series from base 

 to apex of small setiferous tubercles alternatitig with punctures, 

 the setae long and erect ; declivity cariuate below, very slightly im- 

 pressed on each side, chiefly over the 2nd interstice, and not 

 evidently retuse or flattened. Underside concolorous, the legs 

 somewhat lighter, the anterior tibite subangulate before the apex, 

 the others rounded above, and moderately strongly serrate.

The species is reaiarkably like the Colombian X. 

 grandis', Eichh. ; but it has the eyes larger, convex, more 

 strongly granulated and more approximated in front, the 

 prothoracic elevation post-median, the elytra more 

 obliquely declivous, the interstitial seta3 springing from 

 tubercles throughout, and the first interstice not nar- 

 rowed at the apex.
