NEW BARK BEETLES BLACKMAN 345 



Frons with a large, deep ovate concavity at each side of the median 

 line, extending dorsad from slightly above the epistoma, more than 

 half the long diameter being above the upper border of the eye, sur- 

 faces of concavities opaque, reticulate, apparently devoid of true punc- 

 tures and hairs; with a thick, high, median carina, completely sep- 

 arating the two concavities and extending anteriorly to form the 

 normal contour of the head, its surface opaque and reticulate; side 

 between concavity and eye finely aciculate. Eye small, short oval, 

 remotely separated above and below, inner margin entire, the facets 

 fine. Antenna of the rudis type, club short oval, with first two sutures 

 distinct, sinuate. 



Pronotum 1.16 times as long as wide, widest in middle third, pos- 

 terior outline weakly arcuate, posterior angles rounded; sides sub- 

 parallel on posterior two-thirds, very broadly rounded in front, ante- 

 rior margin not truly serrate; anterior area with rather numerous 

 broad, low asperities, summit low ; posterior area granulate-punctate, 

 interstices reticulate ; pubescence apparently lacking on posterior area, 

 inconspicuous on asperate area. 



Elytra very slightly wider than pronotum and 1.50 times as long, 

 1.69 times as long as wide ; sides subparallel on anterior three-fourths, 

 strongly rounded posterolaterally, with a prominent sutural apex ; sur- 

 face moderately shining; striae weakly impressed, very closely, rather 

 coarsely punctured ; interspaces narrow, very sparsely and finely punc- 

 tured, becoming granulate posteriorly, with a few very small, incon- 

 spicuous hairs. Declivity convex, rather steep, coarsely granulate; 

 suture not elevated ; third, fifth, seventh, and ninth interspaces more 

 elevated, with coarse granules or small tubercles; with an indefinite 

 elevation at each side in third interspace in upper half of declivity; 

 sutural apex prominent, densely granulate, its sides meeting at an 

 angle of about 90 degrees. 



The specimen here described is probably a male. No female has 

 been seen.
