Key to the Species. 



Pygidium clothed with short erect setse ; base 

 of pronotum scarcely emarginate in the 

 middle pusillus, sp. n., p. 117. 



Pygidium not clothed with setfe ; base of pro- 

 notum very gently emarginate in the

93. Pogonopiis pusillus, sp. n. 



Shining black, with a slate-grey opaque covering upon the 

 vertex of the bead, the pronotum, scutelkim and elytra, with two 

 small anterior spots on each side of the 

 pronotum ; the three angles of the scutellum, 

 the posterior half of the elytral suture, the 

 humeral and apical calli and parts of the 

 outer margins, denuded and shining ; 

 decorated with silvery-blue markings form- 

 ing a lateral border on each side of the 

 pronotum, and upon the posterior half of 

 each elytron an irregular outer border 

 extending to the suture and two small 

 spots near the suture. The pygidium has 

 also a large irregular patch on each side, 

 Fig. 27. and the sides of the sternum, a patch on 



Pogonopus pusillus. ^.j^g bind coxa and a marginal row of spots 

 on each side of the abdomen beneath are of 

 the same colour. The head, pygidium and sides of the body 

 beneath are clothed with yellow setae. 



It is a very small insect, elongate-oval and convex in shape. 

 The chjpeus is granulated, with its front angles very sharp. The 

 pronotum is distinctly punctured except in the middle and the 

 basal margin is gently curved, with a hardly perceptible sinuation 

 in the middle. The scutellum is short but rather sharp at the 

 apex. The elytra bear large horseshoe-shaped punctures in 

 irregular double rows, extending from the base nearly to the apex. 

 The pygidium is strigose, and the metasternum and abdomen are 

 very smooth and shining in the middle. 



I have seen only a single male specimen, taken by Capt. 

 A. K. W. Downing.
