G. piCEUS, n. sp. 



Its black appearance will at once lead to its recognition. 



I have only seen two specimens ((j^ & $ ), the latter in the col- 

 lection of Mr. Douglas, sent to liim by the late Mr. T. J. Bold ; the 

 former in my own collection, taken by Mr. T. AVilkiiison near Scar- 

 borongh some years ago. The insect has been submitted to M. 

 Lethierry and Mr. J. Sahlberg, and was returned as unknown to them. 



Crown pale testaceous, with a triangular black spot in front before the anterior mar- 

 gin, sometimes continued in a linear form as far as the ocelli ; in the middle two 

 black spots about equidistant from each eye and each other ; near the base and 

 adjoining each eye a small black spot, sometimes obGolete. Face pale or some- 

 what grcj-ish-teslaceous, with about nine transverse, curved, black streaks, 

 frequently united by a black border interiorly, and leaving a fine, palo, central 

 line. Clypeus and lorce pale, tlie former with a more or less distinct small black 

 or brown spot near the apex. Elytra as long as the abdomen, pale testaceous ; 

 claval suture narrowly brown ; inner margin of all the nerves finely reticulated 

 with brown, the reticidation more prominent in some individuals than in others, 

 and not unfrequcntly altogether wanting. Thighs : 1st pair with a short black 

 dash on the inside at the base, and two of the same colour on the lower 

 margin. Length, 2 — 2 J lines 7. OBSOLETUS, Kirsehb. 



The characters on the el3'tra are somewhat similar to those of A. 

 sonlidus ; but the above insect is always much paler and larger than 

 that species, and, iudepcudently of this, the markings on the head are 

 entirely diifcrent.
