the African Species o/Hedybius. 451 



The elytra are coarsely punctured (as in Hedijbius diversi- 

 pennis, Pic), and the second joint of the anterior tarsi in ^ 

 is raised above the base of the third, as in Attalus.

 very deep, smooth, inter-ocular excavation, the latter with 

 two small dentiform tubercles in front and another in the 

 centre, and a stout, erect prominence on each side anteriorly, 

 the vertex sharply, triangularly raised and deeply sulcate 

 down the middle, the raised space preceded by two small 

 poriect fascicles of yellowish hairs ; anterior tarsal joints 1

Hab. S. Africa, Cape of Good Hope^ {iyp^ of Erichson)^ 

 Willowmore* [Dr. Brauns), Matjesfontein^^ (£". Simoti), 

 Maritzburg, Natal (Mus. Cape Toiun). 



The above description of the (J -characters is taken from 

 specimens from Willowmore, whence Gorham's type of 

 H. Icetus was obtained, the latter agreeing well with 

 Erichson's diagnosis of the same sex. Various ? ? doing 

 duty for /. corniculatus in the British Museum and in the 

 Hope Collection at Oxford are, however, referred to a 

 different species, /. duplocinctus. This is a hairy, nigro- 

 violaceous insect, with a granulate prothorax and very 

 coarsely punctured elytra, the latter with a sutiirally- 

 interrupted ante-median fascia and. the apex orange-red. 

 Two ^ c? 3,nd four ? $ of /. corniculatus have been 

 communicated by Dr. Peringuey, and these are all I have 

 seen. M. Simon found it in numbers on an Atriplex, in the 

 dried-up bed of a river, on a stony arid plateau, 30 leagues 

 N.E. of the Cape. In the accompanying fig. 1 (PI. Xlll.) 

 the head is drawn forward from its normal position.
