A astral kill <nid Tasiimnian Coleopffra. 169 



strongly inflated to middle, and then rather stronfi;ly narrowed 

 to apex ; a distinct longitudinal impression in middle of both 

 surfaces. Prothorar about once and one-third as wide as 

 long, sides rounded in front, and feebly diminishing in width 

 *to base, with a shallow but distinct medio-basal impression ; 

 punctures as on head. Elytra with dense punctures, rather less 

 crowded on disc than elsewhere ; sutural stria distinct. 

 Abdomen with fovea strongly transverse, each side at base with 

 a feebly raised oblique ridge, each side at apex continued as a 

 strong oblique impression ; under siu'face with a large and 

 almost circular fovea. Metasternum almost flat along middle, 

 edentate at apex. Femora, for the genus, rather thin; tibiae 

 inflated at apex, the middle pair strongly mucronate at apex. 

 Length If mm.

Each antenna is suddenly inflated about the middle, but the 

 inflation is not uniform on both sides, being slightly nearer to 

 the base on the inner than the outer side, from some directions 

 the inner inflation appears almost tuberculate. From the side 

 each appears to have the basal half thin (the thinnest portion 

 being just before the expanded part) with the apical half 

 strongly inflated. The apex itself is oval. The oblique con- 

 tinuations of the abdominal fovea are very distinct.

Head rather wide and almost flat, not depressed along middle, 

 densely punctate. Antennae wide and flat, slightly shorter than 

 head, strongly inflated to about middle, and thence almost 

 parallel-sided, without median impression. Prothorax about 

 once and one-fourth as wide as long, widest near apex, thence 

 feebly diminishing in width to base ; punctures as on head, with 

 a fairly large medio-basal fovea. Elytra with dense pimctures, 

 becoming sparser on disc, and with on each a small almost 

 impunctate spot at about the middle at the apical third ; sutural 

 stria rather feeble. Ahdornen with basal fovea very large, and 

 posteriorly regularly decreasing in depth, instead of being
