hus infra hand canaliculatis, Ocxdi magni, tenue granulati. 

 Corpus modice convexum. 



The femora in this genus are only grooved at the apex in 

 the ordinary Ivay ; the tibire, therefore, do not admit of being 

 lodged in them as in those genera in which they are canalicu- 

 late or grooved in their whole extent.

Semiathe ophthalmica. 



S. subelliptica, oblonga, nigi'a, nitida ; capite parvo ; rostro prothorace 

 breviore, basi vix latiore, subtilissimc punctulato ; antennis sub- 

 testaceis ; oculis subapproximatis ; prothorace basi latitudine 

 parnm longiore, leviter subvage punctulato ; scutello suborbicu- 

 lari ; elytris prothorace plus duplo longioribus, pone basin latiori- 

 bus, seriatim leviter punctulatis, interstitiis latis, apiccm versus

Hah. Mysol. 



Xychusa. 



Rostrum subtenuatum, depressum. CJava ovata, distincta. Ocrili 

 tenue granulati, approximantes. Prothorax utrinque valde ro- 

 tundatus, basi paulo constrictus, sulcato-marginatus. Ehjtra 

 ovata, prothorace vix latiora. Femora infra baud canaliculata, 

 dente parvo instructa ; tibia', hand sulcatae ; coxoi intermedia; et 

 posticaj utrinque fere contigua). Metasternum brevissimum. Cte- 

 teris ut in Idotasia. 



In the form of the prothorax, narrower at the base than in 

 the middle, and in its grooved margin, this genus differs from 

 all the preceding 5 like Idotasia and Semiathe^ it has also the 

 upper edge of the femora covered with white scales. 



Xyclnisa larvata. 



X. subangustc ovalis, nigra, nitida, elj'tris piceo-luteis ; capite supra 

 convexo, subtilissimc crebre punctulato, inter oculos squamis
