496 REVISION OF THE AUSTRALIAN SPECIES OF BOLBOCERAS, 



B. Sloanei, Blackb. 



This is the only species known to me having multicarinate hind 

 tibiae, the frontal horn of the male unarmed, and the frontal 

 wings of the female normal, in which the front tibiae have a well- 

 defined 6th external tooth. 



B. Reichei, Guer. 



The female of this species must be regarded as undescribed, 

 inasmuch as the description and figures supplied by Westwood 

 are not sufiiciently explicit to distinguish it from other female 

 Bolbocerata. Westwood says that B. Kirbii, Bainbridge, is female 

 Reichei, but does not state whether his own description of female 

 Reichei is founded on Bainbridge's description (or specimen) or on 

 an independent specimen in his own collection. When Bainbridge's 

 description of B. Kirbii is referred to it is at once apparent that 

 he has described two females (probably of two species) as male 

 and female of his insect. I think it not unlikely that at least 

 the example which he regarded as a male was the female of 

 Reichei, but that cannot be regarded as more than probable, as 

 Bainbridge himself does not associate it with male Reichei. The 

 description itself is fairly explicit, but does not seem to me 

 capable of being applied confidently to any Bolboceras in parti- 

 cular, for the numerous details given happen to be those which 

 are common to nearly all the females of the group having multi- 

 carinate hind tibiae. As Kirbii was a nom. preeocc. in the genus, 

 however, it is not of great importance to identify Bainbridge's 

 insect. I have not myself seen any female Bolboceras that I can 

 regard as being Reichei. I am afraid the matter can be cleared 

 up only by a collector in some locality where B. Reichei occurs. 



B. CORNUTUM, Macl. 



A male specimen in the S. A. Museum which was brought by 

 the Calvert Expedition from N.W. Australia agrees very well 

 with the description of this species. It has multicarinate hind 

 tibiae. It will be readily recognised by the characters indicated 

 in my tabulation, which add some particulars to those furnished
