COLEOPTERA. 277 



and a russet yellow spot at their extremity: their external 

 margin of the same colour; posterior angles of the thorax pro- 

 longed into a point. 

 The elytra of the others are smooth or but slightly sulcated. In 

 the environs of Paris the following species are usually to be found. 

 Brack, crepitans^ Fab.; Hist. Nat. des Coleop. d'Eur., II, viii, 

 6; Panz., Faun., Insect. Germ., XX, 5. Average length four 

 lines; fulvous; elytra sometimes deep blue, at others bluish- 

 green, and slightly sulcated; antennae fulvous, but the third and 

 fourth joints blackish; the pectus, its middle excepted, and the 

 abdomen, black. This species has been confounded with the 

 explodens of Duftschmid — Hist. Nat. des Coleop, d'Eur., II, 

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

 the crepitus, with blue and almost smooth elytra. The gla- 

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

 on the antennae. 



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

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

 A fulvous spout 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 de- 

 partment of Herault(l). 

 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 poste- 

 rior extremity of the elytra, it is true, does offer a deep emargina- 

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

 truncated. Several species of this division also present the same 

 sinus, although 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 Cymindisfusula of the Russ. Entomog., of Fischer, I, xii, 3. It
