hus infra hand canaliculatis. OnUi magiii, teiuie granulati. 

 Corpus modice convexum. 



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

 the ordinary way ; the tibiae, tlierefore, 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, nigra, nitida ; capite parvo ; rostro prothorace 

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

 tcstaceis ; oculis subapproximatis ; prothorace basi latitudine 

 parum longiore, leviter subvage punctulato ; scutello suborbicu- 

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

 bus, seriatim leviter punctulatis, interstitiis latis, apicem versus 

 Antta abbreviata albo-squamosa decoratis; pedibus picco-nigris,

Xychusa. 



Rostrum subtenuatum, depressum. Clava ovata, distincta. Ocnli 

 tenue granulati, approxiraantcs. Prothorax utrinque valde ro- 

 tundatus, basi paulo constrictus, sulcato-marginatus. Elytra 

 ovata, prothorace vix latiora. Femora infra baud canaliculata, 

 dente parvo instructa ; tihice baud sulcatse ; cox(b intermedi^e et 

 posticfe utrinque fere contiguae. Metasternum brevissimum. Caj- 

 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 ; like Idotasia and Semiathe, it has also the 

 upper edge of the femora covered with white scales. 



Xychtisa larvata. 

 X. subanguste ovalis, nigra, nitida, elytris piceo-luteis ; capite supra 

 convexo, subtilissime crebre punctulato, inter oculos squamis
