 viii, 7 which is also very common. It is but half the size of 

 the crepitus, with blue and almost smooth elytra. The glabratus, 

 Bonelli, only differs from it in the absence of the spots on the 

 antennae. 



Brack, sclcpeta, Fab. ; Hist. Nat. des Coleop. d'Eur., II, ix, 3. 

 Very similar to the last, but distinguished from it as well as 

 from the preceding ones by the suture of the elytra, which is 

 fulvous-red from the base to the middle. The body also is 

 wider in proportion, and of the same colour above and beneath. 



Brack, bombarda, Illig. ; Hist. Nat. des Coleop. d'Eur., II, ix, 

 2. This species is intermediate between the last and the first. 

 A fulvous sprout surrounds the scutellum, but does not extend 

 along the suture. 



Brack, exhalans, with elytra of an obscure blue, and four yel- 

 lowish spots, and Brack, causticus, all fulvous, with a band along 

 the suture and posterior spot blackish are found in the depart- 

 ment of Herault*. 



In the Hist. Nat. des Coleop. d'Eur., we placed the genus Catas 

 copus of Kirby next to Brachinus. A more recent examination 

 leads us to think that it rather belongs to the Simplicimani. The 

 posterior extremity of the elytra, it is true, does offer a deep emargi- 

 nation, but it terminates in a point towards the suture, and is not 

 truncated. Several species of this division also present the same 

 sinus, though less deep and acute. 



Between the Brachini and the Catascopi, Count Dejean Species 

 I, p. 226 places the genus Corsyra of Steven, the type of which is 

 the Cymindis fusula of the Russ. Entomog., of Fischer, I, xii, 3. It 

 differs from the latter in its tarsi, the hooks of which are simple. 

 The body also is flattened, as in the preceding and other neighbouring 

 subgenera, tolerably broad, with filiform palpi, unidentated mentum 

 and transverse labrum ; the thorax is wider than the head, and nearly 

 semi-orbicular. 



But one species is known. 



The other Carabici of the same division with equally simple hooks 

 are removed from the preceding by the form of their head, which is 

 suddenly narrowed immediately after its origin, presenting the ap- 

 pearance of a neck or rotula. 



First come those in which the tarsi of both sexes are identical, sub- 

 cylindrical or linear, and whose penultimate joint, at most, is deeply 

 notched or bilobate. 



Sometimes the exterior palpi are filiform or but slightly enlarged 

 at the end, with the last joint verging to an oval ; the head has the 

 same form and becomes gradually narrowed behind the eyes. The 

 first joint of the antennae is always short or but slightly elongated. 

 The thorax is always narrow and elongated. The body is thick.
