Dr. Schaum on four new Genera of Carabide. 75 
as in the Ozenide. Antenne almost of the length of the head and 
thorax *, much more slender than in the typical Ozenide, resembling 
those of the genus Physea, Brull., with the three basal joints smoother 
than the rest. Labrum short, emarginate, with produced angles. Mentum 
with a single tooth in its middle. Prothorax rather elongate, with the 
disk elevated and callous, and a broad oblong impression on each side 
between the callus and the elevated margin. Mesosternum very narrow 
between the intermediate coxa, but still separating them and receiving 
the attenuated apex of the metastenum. Episterna and epimera of the 
mesothorax completely soldered together, forming a large portion of the 
intermediate acetabula. Episterna of the metathorax elongate as in 
Ozzenidee, epimera conspicuous. Elytra elongate, impressed on each 
side a little before the middle, so that the margin forms here a little 
sinus. Anterior and intermediate tibie a little flexuous inside, ciliate, 
the anterior a little dilated before the apex, without any trace of emar- 
gination, and with but one very small spur at the inner extremity. 
Abdomen with the second and ventral segment connate. 
Tylonotus Fry. (Pl. IV. fig. 2.) 
T. testaceus, parce pilosus; capite prothoraceque levigatis, hoc fossula 
media anteriore; elytris dorso obsolete striatis, interstitiis alternis 
seriatim obsolete punctatis——Long. 4 lin. 
The only specimen I am acquainted with is in the collection of 
A. Fry, Esq., who took it in the Brazils (Espiritu Santo). — 
Boruynoptera [trib. Lebiade]. 
Caput postice constrictum ; oculis magnis, valde globosis. 
Labrum transversum, apice subrotundatum. 
Mandibule breves, late, deplanate, parum arcuate. 
Palpi articulo ultimo ovali. 
Mentum medio emarginatum, membrana basali valde conspicua, para- 
glossa cum ligula connata. 
Prothorax subquadratus, lateribus sinuatus, basi truncatus, supra depla- 
natus. 
Elytra postica sublatiora, apice late emarginata, dorso foveolis majoribus 
impressis. 
Tarsi articulo quarto bilobo, unguiculis valde pectinatis. 
In the great number of genera composing the tribe of Lebiade 
three different types may be distinguished, the Cymindes, Dromii, 
and the genuine Lebiade (cf. Lacord. i. p. 102; LeConte, Classif. of 
Col. p. 23). The genuine Lebiad are represented by those genera 
in which the head is constricted behind, and in which the mentum 
is not distinctly toothed but has the emargination more or less 
* They are a little too short in the figure.
