REVISION OF THE GENUS SEIROTRANA, TOGETHER 

 WITH DESCRIPTIONS OF NEW SPECIES OF 

 OTHER AUSTRALIAN COLEOPTERA. 



By H. J. Carter, B.A., F.E.S. 



Seirotrana Pascoe. 

 Journ. of Ent. ii. I86«, p.483. 



TENEBRIONIM. 



In 1866 Pascoe formed the genus Seirotrana for the reception 

 of Adelium catenulatum Boisd., describing its distinguishing 

 characters in fifteen words, " Characteres utin Adelio; sed elytra 

 prothoraci arete applicata. Antennae articulo tertio duobus 

 sequentibus breviore." 



It is a pity that Pascoe did not add Blessig's excellent char- 

 acters for differentiating this genus from Adelium, since the 

 latter's third class of Adelia, consisting of A. parallelum, A. 

 elongatum and A. catenulatum are specially described as having 

 "the abdominal process* quite margined, abruptly truncate " ; 

 and he adds, "they are of elongated form, the intervals on the 

 elytra are alternately shallow and elevated." Another character, 

 which though not common to all the species, is true of thirteen 

 out of the twenty species herein specified, is the crenulated sides 

 of the prothorax. 



A better character for differentiating Seirotrana from Adelium 

 and from Goripera is the form of the epipleura, which in Coripera 

 is nearly vertical, in Adelium rounded or much more acutely 

 joined to the elytra, in Seirotrana it is narrower and intermediate, 



* I have already spoken of this in my revision of Adelium as the " inter- 

 ooxal process."
