not abruptly elevated between, the coxge ; the process 

 horizontal, lanciform, bisiilcate between the coxas ; meso-

Thettea, nov. gen. 



Mentum trapezoidal, regularly convex, not keeled down 

 the median line ; epistonia broadly truncated in front, the 

 suture angulate and strongly impressed ; front somewhat 

 rapidly sloping to the epistoma ; antennary orbits promi- 

 nent ; antennas rather short and slender, thickening out- 

 wardly, scarcely depressed ; joints 3 — 7 obconic ; 3 elon- 

 gate ; 4 — 6 subequal in length, but gradually broader ; 

 8 — 10 still larger and wider, subtriangular ; 11 twice the 

 length of 10, apex obliquely rounded ; pro thorax but little 

 convex, well margined throughout except at the middle of 

 the apex ; lateral margins entire ; front angles distinctly 

 sharper than in the preceding genera ; sides slightly, and 

 obliquely, widened to behind the middle, thence obliquely 

 narrowed to the base ; base feebly bisinuate, hind angles 

 subrectangular ; scutellum curvilinearly triangular; elytra 

 much broader than the prothorax, gently and regularly 

 convex, dilated posteriorly ; shoulders prominent, broadly 

 rounded ; prosternum abbreviated before, and abruptly 

 elevated between, the coxEe ; the process rather short, lan- 

 ceolate ; mesosternum vertical in front, its cavity widely 

 U-shaped; apex of intercoxal process narrowly rounded; 

 legs slender ; tarsi very long and slender, the three first 

 joints of the anterior dilated ; the last joint of the posterior

Head and prothorax bronzy-black, finely, obscurely and

 coppery-asneous on the intervals, vivid green down the 

 stride ; strongly striated, the strise closely set with very 

 distinct, clearly impressed, rounded punctures ; intervals 

 equal, moderately convex, impunctate, delicately rugulose ; 

 imderside black, moderately nitid ; epipleui-al fold with two 

 or three irregular rows of very distinct punctures down
