partly erect ; head punctulate, with the arcuate transverse frontal 

 impression very conspicuous, having across the eyes another, also 

 arcuate impression ; antennae very long in both sexes, joints five to 

 ten in the shape of an elongated truncate cone, nearly as broad as 

 long at apex, and with the apical one slightly longer than the two 

 preceding taken together and acuminate at the tip in the male ; in 

 the female the fifth to tenth antennal joints are similarly shaped, but 

 shorter, and the ultimate one is not quite as long as the preceding two 

 taken together ; prothorax narrower in the male than in the female, 

 rounded and ampliated laterally in the anterior part, strongly con- 

 stricted above the basal, impunctate on the discoidal, and without 

 any traces of a median groove, while in the female there is a very 

 plain longitudinal one in the centre only of the disk ; scutellum 

 small, punctulate; elytra sub-parallel in the male and only slightly 

 ampliated in the posterior part, broadly ampliated and much more 

 convex in the posterior part in the female, distinctly costulate, and 

 faintly striate, very closely punctate and with irregular, transverse , 

 very wavy raised folds ; under side very briefly pubescent, the 

 pubescence appressed and greyish-white ; the two basal tarsal joints. 

 very long, especially in the male. 



The difference in the sculpture of the thorax of the two sexes seems 

 to be quite peculiar to this species. 



Length 9-94- mm. ; width 4-4J mm.

LAGKIA VITTATIPENNIS, n. sp. 



Posterior part of the head fuscous black ; prothorax deeply infus- 

 cate except along the anterior and posterior margins, which are 

 testaceous, scutellum and elytra testaceous, the latter with two 

 fuscous bands, the first dorsal, the other supra-lateral, on each side, 

 legs fuscous with the basal part of the femora and the apical part of 

 the tibiae testaceous; clothed above with a moderately dense, upright 

 pubescence ; antenna? black, long, the four penultimate ones robust, 

 but not much transverse in the male, and with the apical one not 

 quite as long as the three preceding taken together, in the female 

 these joints, with the exception of the two penultimate, are some- 

 what elongated and slender, and the last one is not equal in length 

 to the two preceding ones also taken together ; head scrobiculate 

 and having a triangular somewhat smooth ridge in the anterior part; 

 prothorax longer than broad, cylindrical, scrobiculate-punctate ; 

 elytra slightly ampliated in the posterior part in the male, strongly
