46 REVISION OF THE SUBFAMILY TENEBRIONIN^:, 



securiform. (2) 'J'lie posterior intorcoxal process in botli is narrow, 

 triangular, or very little rounded at apex; whereas in Tenebrio- 

 nincE and Cyphalevufn, this process is generally widely rounded. 

 (3) The legs and tarsi form the greatest barrier to the inclusion 

 of these genera in either group — widely differing from the Tene- 

 hrioninrjR in their more elongate form, clothed as to their tibiae 

 and tarsi with long hairs; while equally distinguished from the 

 Cyp}tahi7i(n by their unusually long tibial spurs and tarsal claws. 

 The author suggests (1) that Brises = Ephidonius; (2) that Brises, 

 at present, be considered as a single subgroup of the Tenebrionin(n. 

 I cannot find any satisfactory character, beyond sculpture, to 

 separate the two genera; and in the case of the new species, B. 

 Blairi, the sculpture is intermediate between that of B. trachy- 

 notoideH Pasc, and E. Duhoulayi Tiates. The name Epkidoni'ns 

 should, therefore, be surjk, and the species may be tabulated as 

 follows, all of them being before me.

The two following genera, A.sphalus and J/ypaulax, may be 

 grouped as Cf/ilorrtetopnnai, only distinguished from "Tenebrionides 

 vrais" of Lacordaire, by their short metasterruim arid apterous 

 body.
