188 CLASS INSECTA. 



We had at first (Hist. Nat. des Coleop. d'Eur.) placed 

 the genus Catascopus of Mr. Kirby, after the Brachini. We 

 think, from a new examination, that it rather belongs to the 

 section of the simplicimana. The posterior extremity of the 

 elytra presents clearly a profound emargination, but it termi- 

 nates in a point on the side of the suture, and is not truncated. 

 Many species of this division present also the same sinus, 

 although however less profound and less acute. 



Between the Brachini and the Catascopi, M. Le Comte 

 Dejean (Spec. T. p. 226,) places the genus Corsyra of Mr. 

 Stevens, which has for its type the Cymitidus fusula, of the 

 Entomographie of Russia, by M. Fischer, I. xii. 3. It 

 differs from this last in its tarsi, the crotchets of which are 

 simple. The body otherwise is flatted, as in the preceding, 

 and the other neighbouring sub-genera, short, tolerably 

 broad, with the palpi filiform, the mentum unindented, the 

 labrum transverse, the corslet broader than the head, and 

 almost semi-circular. 



But one species is known. The other carabici of the same 

 division, and whose crotchets are likewise simple, are re- 

 moved from the preceding by the form of their head, which 

 is contracted abruptly from its origin, and presents the 

 appearance of a neck or rotula. 



First, come those whose tarsi are almost identical in the 

 two sexes, sub-cylindrical, or linear, and of which the penul- 

 timate articulation for the most part, is profoundly emargi- 

 nated, or bilobate. 



Sometimes the external palpi are filiform, or but little 

 swelled at the end, Avith the last articulation almost ovali- 

 form. The head has the same form, and contracts gra- 

 dually behind the eyes. The first articulation of the an- 

 tennae is always short, or but little elongated. The cors- 

 let is always narrow and elongated. The body is tolerably 

 thick. The emargination of the mentum exhibits a tooth
