248 THE GENERA AND SPECIES OF AMYCTERIDiE, 



tuberculato tertio piano reliqais crebre seriatim tubercula- 

 tis apice subdehisceatibus obtuse mucrouatis. 



Long. 9| lin., lat. 4 lin. 



Hab. Soutli Australia. 



This is a broad and rather flat insect ; the head and rostrum 

 are strictly typical of the • genus, on the summit of the former 

 there are two patches of brown scales, all the rest of the upper 

 surface of the body being thickly covered with cinereous scales. 



The thorax is broad, rather flat, slightly lobed above and 

 considerably behind the eyes, slightly broader in the middle than 

 in front, with a slight transverse impression near the apex, 

 and rather thickly covered all over with small oval slightly 

 flattened tubercles, each furnished with a decumbent black seta. 

 The elytra are also rather flat, are scarcely broader than the 

 thorax, and terminate in a slightly separated obtuse point. 



The sculpture consists of numerous rows of large punctures 

 with the interstices of various kinds, thus the suture has on each 

 side a row of fine granules furcated and tuberculated at the 

 scutellum ; the first interstice is composed of three or four small 

 distant conical tubercles, the second of conical tubercles placed 

 rather closely, the third is entirely without tubercles, while the 

 next two are very closely tuberculated. On the suture and the 

 fourth interstice, the scales are nearly white. The abdomen 

 beneath, is marked with thin patches of yellow scales in the 

 middle, and whitish patches on the side of each ventral segment. 

 The legs are thinly covered with white scales and black set£e. 



I have been thus particular in my description of this species, 

 because many South Australian insects approach it nearly. And 

 I shall mostly characterize them by the diSerences which they 

 may present to this, the first described species of the group.
