dilatatse, rotundatse. Articulus ultimus palporum maxillarium 

 ad basin cylindriciis, in medio tnmidus, ad apicem acuminatus ; 

 articulus ultimus palporum labialium similis, sed minus tu- 

 midus et minus acuminatus et truncatus. Mandibuli fortes, 

 densi, dexter intus bidenticulatus, sinister unidenticulatus. 

 Labrum quadratum. Caput mediocre^ baud retro coarctatum. 

 Oculi satis prominentes. Antennse ad instar capitis et pro- 

 tboracis longitudine ; articuli primus, tertius et quartus longi- 

 tudine sequales, cseteris longiores, et, cum secundo (brevioi'e), 

 obconici, quintus et sequentes parum depi'essi. Protborax 

 subquadratus, parum retro coarctatus ; anguli antice rotuu- 

 dati, postice distincti. Elytra prothorace paullo latiora, 

 parum elongata, parallela, ad apicem sinuata. Pedes medi- 

 ocres : tibise anteriores parum dilatatse et versus apicem extus 

 denticulatee ; tibiae intermedise et posteriores baud denticu- 

 latifi ; tarsi subtus fortiter ciliati, anteriores et intermedii 

 maribus dilatati, articulis quatuor primis triangularibus, primo 

 longiore, quarto bilobato in omnibus tarsis, posterioribus baud 

 dilatatis. Corpus satis elongatum. 



In general appearance tbe species composing this genus ap- 

 proach nearer to the American genus Geopinus than to any other 

 which I have seen, but are readily distinguished from it by the 

 possession of a median tooth to the mentum, besides the other 

 characters above mentioned; their form also is less convex, and 

 approaches more nearl}'^ to Anisodactylus. The place of the 

 genus seems to be next to Dejean's and Schmidt-Goebel's Indian 

 genus Batoscelis, as defined by Lacordaire, from which it differs 

 in the following respects : — its mentum is deeply, instead of 

 being feebly emarginate ; its ligula is small, instead of being 

 "asscz grande;" its paraglossse are rounded instead of being 

 truncate, and can scarcely be called arched. In other respects 

 the characters seem almost the same. The bilobed fourth joint 

 of the tarsi is not noticed in Lacordaire's description. Probably 

 it would have been better for mc to have widened the characters 

 of the genus Batoscelis, so as to have admitted the following 

 species, instead of making a new genus for them ; but the dif- 

 ference of their native country has induced me to separate them.
