fifth, and a small spot near the apex. Beneath aeneous, with a strongs 

 purplish tinge. 



Head nearly flat, with a broad obsolete depression on the front, 

 and a very short elevated carina on the occiput ; surface densely and 

 coarsely punctate, the punctures rather shallow, and narrowly sepa- 

 rated from each other, and from each puncture arises a rather long, 

 erect inconspicuous hair, the intervals smooth ; epistoma broadly and 

 deeply arcuately emarginate in front, forming an obtusely angulated 

 lobe on each side of the emargination ; antennae serrate from the 

 fifth joint. Pronotum strongly transverse, moderately convex, two 

 time as wide as long, distinctly narrower in front than behind, 

 widest at base, with a narrow obsolete depression along the anterior 

 margin, broadly interrupted at the middle, and with three more or 

 less obsolete basal depressions, one median, and one on each side at 

 the inner margin of the yellow spot, w^hich is not elevated; sides 

 obliquely expanded from anterior margin to posterior angles, which 

 are rectangular, the margins very narrowly flattened, and not visible 

 posteriorly from above; anterior margin feebly arcuately emarginate, 

 with a distinct angulated lobe at middle ; base transversely truncate ; 

 surface densely and coarsely punctate, the punctures finer and more 

 widely separated on the disk, becoming coarser, deeper, and more 

 narrowly separated toward the sides, and from each puncture arises 

 a long, erect inconspicuous black hair, intervals smooth and shining. 

 Eytra moderately convex, slightly flattened on the disk posteriorly, 

 slightly wider than pronotum at base ; sides slightly expanded behind 

 the humeral angles, feebly sinuate and obliquely attenuate to the apical 

 third, then rather strongly arcuately attenuate to the tips, which are 

 conjointly, rather broadly rounded, the lateral margins coarsely 

 serrate, the teeth irregular and widely separated; humeri strongly 

 developed; surface striato-punctate, the striae impressed toward the 

 apex, about as wide as the intervals on the basal region, but becom- 

 ing narrower on the flattened apical areas, the punctures large, 

 deep, and irregularly placed in the striae, becoming finer and more 

 elongate near the apex, the intervals not elevated, smooth, and with 

 a single row of distant punctures, from which arises a rather long, 

 semierect hair. Abdomen beneath sparsely and rather finely punc- 

 tate, the punctures much coarser and more widely separated on the 

 basal segment, becoming finer toward the apical segment, and rather 

 densely clothed with long semierect cinereous hairs, intervals 

 smooth; last segment subtruncate at apex, and without a subapical 

 carina. Prosternum coarsely and densely punctate, and sparsely 

 pubescent ; anterior margin with a narrow rectangular lobe at middle, 

 which is elevated and truncate in front; prosternal process parallel 

 to behind the anterior coxal cavities, nearly three times as wide as- 

 the cavities, and very broadly rounded at the apex.
