352 Mr. J. S. Baly’s Descriptions of 
moderately robust, subfusiform, slightly compressed, two basal 
joints short, nearly equal; the first strongly, the second mode- 
rately dilated; third nearly equal in length to the two pre- 
ceding; fourth, fifth, and sixth short, equal; seventh slightly 
longer; eighth and three terminal joints closely united, their 
articulations distinct. Head smooth, impunctate; eyes pitchy 
black. Thorax at the base more than half as broad again as 
long; sides rounded, narrowed and sinuate in front; above 
subcylindrical, transversely excavated near the base; middle 
of disc with a shallow longitudinal groove; surface coarsely 
punctured, the punctures crowded at the sides. Scutellum 
smooth, its apex obscure purple. Elytra broader than the 
thorax, slightly increasing in width towards the posterior angles, 
the latter produced into a flattened spine, its apex bidentate ; 
sides narrowly margined, their outer border coarsely serrate, 
serrations more distant when approaching the posterior angles ; 
apex obtusely rounded, its margin slightly dilated, serrate ; 
above subdepressed, each elytron with four elevated coste, the 
two outer ones less raised, the second from the outer margin 
being interrupted for nearly the whole of its length ; suture also 
raised, interstices each with a double row of deep punctures ; 
dark metallic purple, each elytron with six bright fulvous 
spots ; one at the base, the second oblique placed on the inner 
disc before its middle; two others beyond the middle, placed 
obliquely, the outer one attached to the lateral margin; the fifth 
transverse, subapical, confluent at the suture with its fellow on the 
opposite elytron, and the sixth narrow and transverse, placed on 
the apical margin, also confluent at the suture. Beneath shining 
fulvous; anterior pair of thighs simple.

head and thorax, robust, indistinctly thickened towards their 
apex; two basal joints equal, subovate, very slightly thickened ;
