apical angles to near middle, then more strongly obliquely narrowed 

 to near the posterior angles, which are feebly expanded, and rather 

 acute; when viewed from the side the marginal carina is strongly 

 sinuate, the submarginal carina feebly sinuate, the two carinae widely 

 separated anteriorly, and connected to each other near base ; anterior 

 margin feebly sinuate, and the median lobe broadly rounded; base 

 angularly emarginate at middle of each elytron, the median lobe 

 feebly produced, and broadly, arcuateiy emarginate in front of 

 scutellum ; disk broadly, transversely, obsoletely depressed near apex 

 and base, a broad, deep depression on each side along lateral margin, 

 and with strongly elevated, sinuatet prehumeral carinae, extending 

 from posterior angles to marginal carinae at middle; surface gla- 

 brous, finely but not closely, transversely rugose at middle, becoming 

 more irregularly rugose toward the sides, and finely, sparsely punc- 

 tate between the rugae. Scutellum moderately, transversely carinate, 

 and the surface finely reticulate. 



Elytra about as wide a pronotum at base, and equal in width at 

 base and behind middle; sides nearly parallel for a short distance 

 behind base, broadly, arcuateiy constructed in front of middle, 

 broadly, arcuateiy expanded behind middle, then obliquely narrowed 

 to the tips, which are separately, rather narrowly rounded, and finely 

 serrulate; disk vaguely flattened, without longitudinal costae, su- 

 tural margins moderately elevated posteriorly, and with broad, deep 

 basal depressions; surface coarsely, densely imbricate-punctate, 

 sparsely clothed with short inconspicuous hairs, and each elytron or- 

 namented with orange yellow pubescent designs as follows : A broad 

 vitta extending along sutural margin from basal fourth to middle, 

 and a slightly oblique, elongate spot at apical fourth. 



Abdomen beneath finely, obsoletely reticulate, finely, sparsely punc- 

 tate, the punctures more or less connected transversely on basal seg- 

 ment, sparsely clothed with short recumbent pubescence, which is 

 denser on each side of middle along anterior margin of basal seg- 

 ment, and with a spot of very dense yellowish pubescence at sides of 

 third segment; sides rather broadly exposed above; first segment 

 convex and without long hairs at middle; last segment broadly 

 rounded at apex ; suture between first and second segments not visible ; 

 vertical portions of the first segment with a spot of dense orange 

 yellow pubescence; pygidium without a projecting carina at apex. 

 Metasternum and external part of posterior coxae densely clothed 

 with orange yellow pubescence. Prosternum densely granulose, finely 

 but not closely rugose, and sparsely clothed with short, recumbent 

 whitish hairs ; prosternal lobe broad, strongly declivous, and broadly 

 subtruncate in front; prosternal process broad, the sides parallel to 

 behind the coxal cavities, then abruptly narrowed to the apex, which 

 is rather acute. Tibiae slender, the anterior pair slightly arcuate and
