76 Dr. Schaum on four new Genera of Carabide. 
filled-in with a basal membrane. Such genera are Lebia (including 
Ina, Eschsch.), Nemotarsus, LeC., Cryptobatis, Sarothrocrepis, Eury- 
celus, Physodera, Singilis, and Plochionus. Of the other genera 
mentioned by Lacordaire the following are, however, to be excluded : 
—Pentagonica, Schmidt-Goebel(= Rhombodera, Reiche), Mochtherus, 
and Arsinoé (= Rhaphidognatha, Murray), which by their large la- 
brum are Pericalide ; Huplynes, Schmidt-G.(=Dyscolus, De}.),which 
is an Anchomenid; Rhopalostyla, which stands better among the 
Cymindes; T'etragonoderus,which approaches nearer the Dromii; and 
Masoreus, which constitutes a type of its own. The genera Prome- 
coptera, Haplopeza, Scalidion, and Dolichoctis are unknown to me. 
Of the genera composing the true Lebiad, to which also Bothy- 
noptera belongs, Lebia, Nemotarsus, Cryptobatis, Sarothrocrepis, 
Physodera, and Singilis have the prothorax more or less pedunculate 
in the middle; while it is truncate in Plochionus, and with rounded 
posterior angles in Eurycelus. It is also truncate in Bothynoptera, 
which is very distinct from the others in the shape of the prothorax, 
in the elytra being broadly emarginate at the apex and having fovese 
on their dorsum, and in the extraordinary size and number of the 
comb-like teeth of the claws. 
Bothynoptera dorsigera. (P1. IV. fig. 3.) 
B. brunnea, capite intra oculos fossulato, ante fossulam macula testacea 
notato ; prothoracis apice et basi fossulatis, lateribus valde deplanatis, 
testaceis; elytris subtilissime striatis, foveis quatuor majoribus seriatis, 
plaga magna dorsali testacea.—Long. 5 lin. 
Discovered by Captain Boys in Northern India. A specimen has 
been given to me by Professor Westwood. 
Acmastss [ trib. Harpalidee ]. 
Caput maximum, postice non attenuatum. 
Antenne capite parum majores, tenues. 
Oculi sat magni, sed parum prominentes. 
Labrum antice subemarginatum. 
Mandibule breves, obtuse. 
Palpi maxillares axrticulo ultimo precedente multo breviore. 
Mentum dente medio minutissimo. 
Rrothorax coleopteris vix angustior, postice angustatus, angulis postice 
rectis, margine subdeplanato. 
Coleoptera ovata, parum convexa. 
Tarsi presertim postict tibiis multo breviores, subdilatati, setosi, antici 
maris simplices. 
Tibiarum calcaria valida, interna preesertim paris intermedii externis 
multo longiora.
