made up of a series of elongate spots placed side by side ; the 

 oblique apical margin of the elytra blue-black, the lateral margins 

 not dark as in the preceding species. Head rugulose-punctate. 

 Antennae reach past the apex of the elytra by about three 

 joints in the $ , and by more than 

 four in the J ; first joint very densely 

 and very finely rugulose-punctate ; third 

 to sixth not spined in either sex; all 

 the -joints pubescent, the pubescence 

 longer and somewhat denser on the 

 underside. Prothorax transverse, but 

 much narrower than the elytra, slightly 

 constricted and marked with a trans- 

 verse groove near base and apex, a little 

 dilated and strongly tuberculate at the 

 middle of each side ; the dark spots on 

 the disc placed on two slight elevations, 

 between which is a median canaliculate 

 depression ; the surface densely rugulose- 

 punctate, sparsely clothed with longish 

 pubescence. Each elytron with two 

 feebly raised dorsal costae which unite 

 at about the middle of the posterior 

 dark band, a single costa continued thence almost up to the 

 apical border ; the surface very finely rugulose-punctate, covered 

 faintly with short grey pubescence. Tips of the femora and tibias 

 and lateral borders of the metasternum, black. Last ventral 

 segment sinuate at the apex in the d , broadly truncate and fringed 

 with reddish-brown hairs in the $ . Intercoxal process of pro- 

 sternum abruptly declivous in front. 

 Length 30-37 ; breadtJt, 9-11 mm.

Group HESPEEOPHANINI. 



Grula without mentigerous process, except in HesperopTianes, in 

 which it is very short ; ligula membranous ; eyes large, deeply 

 emarginate; antennae ciliated, longer than the body in the d"'. 

 Prothorax unarmed at the sides. Elytra rather long, more or less 

 parallel-sided. Front coxae subglobular, more or less angulate at 

 the side ; their acetabula open posteriorly ; the intercoxal process 

 either very little or not at all dilated at the end. Acetabula of 

 middle coxae extended to the epimera. First abdominal sternite 

 not longer than the second except in the middle and at the sides. 

 Wing-venation reduced by the disappearance either of vein Cu 2 

 or of the posterior branch of Cu 1, probably the latter; Cu2 in 

 that case having lost its connection with A 1 appears simply 

 as a branch of Cu 1 .
