Not unlike in general facies T. Wahlbergi, Haag., but the pro- 

 tborax is not so sharply aculeate laterally, nor so much shagreened, 

 and the intervals on the elytra are granulose instead of being 

 roughly scrobiculate. 



TKACHYNOTUS KUSTICUS. 



Niger, opacus, glaber ; caput crebre sed baud profunde punctula- 

 tum ; prothorax basi apiceque truncatus, medio sub-angulatim dila- 

 tatus, fere hexagonus, longitudine quarto latior, parum convexus, 

 crebre punctulatus, intra basim obsolete transversim impressus, 

 linea longitudinali media apice posticeque abbreviata ; elytra elongate 

 ovata, basi prothorace nonnihil angustiora, medio ampliata, ubi pro- 

 thorace duplo latiora, versus apicem acuminata, supra modice convexa, 

 crebre granulata, sutura elevata, praeter carinam lateralem, reflexam, 

 costis sub-acutis discoidalibus duabus alteraque externali vix distincta 

 apicem baud attingentibus in singulo prsedita ; subtus brevissime 

 pubescens ; pedes sat graciles, brevissime pubescentes. Long. 13- 

 14 mm. ; lat. 6-7 mm. 



Somewhat of the same shape as T. acnminatus, Queens., but with 

 more ovate elytra, also acuminate behind, but a little more convex 

 and with less sharp dorsal carinoe.
