The female insect, figured in PI. VII. fig. 1, being unique, 

 we do not possess the means of its sexual identification as 

 the female of the Gol. albo-pictus, although there can be 

 but little doubt that such is the case. 



It is black, varied on the hind part of the head, pro- 

 notum and elytra with white markings. The head is 

 thickly punctured, oval in fi'ont, with two impressions 

 between the eyes bearing two small somewhat triangular 

 white spots. The mandibles have the horny part slender 

 (PI. VII. fig. la). The maxilla3 (PL VII. fig. lb) have 

 the upper lobe horny, terminated by two obtuse teeth, or 

 rather its apex is emarginate ; the lower lobe forms a strong 

 curved spine. The mentum (PI. VII. fig. \c) is not so 

 broad as in the male, rounded at the sides, deeply 

 notched in the produced centre of its anterior margin. 

 The prothorax is sub-heptagonal, the middle of the 

 anterior margin forming a small tubercle, the hind margin 

 produced and rounded over the scutellum ; the anterior 

 half of the lateral margin diverges considerably from 

 the head, but the posterior sides converge towards the 

 humeral portion of the elytra; the middle of the disc 

 has a deep impression, extending from the centre to the 

 front tubercle ; the disc is densely covered yviih punctures 

 of large size, especially towards the posterior margin ; 

 down the centre of the depression is a slender ^vhite 

 line; another short, conical extends on each side obliquely 

 from the front tubercle ; there is a moderately wide white 

 mark parallel to the lateral margin, united at each end 

 with a very slender one. 



The scutellum is smooth, with a strongly impressed ime 

 on each side. The elytra are covered with very mmute
