A single male specimen was contained in the collection 

 bequeathed by the late Alexander Fry to the British 

 Museum. It appears to be most marly related to Plusiotis 

 aurigans, Roths. & Jord., but is entirely shining above, with- 

 out opaque clypeus, pygidium, or prothoracic borders. The 

 mandibles are uniformly rounded externally and not deeply 

 siimated as in P. aurigans. 



The colour is a pale greenish gold above, with the clypeus, 

 forehead, sides of the pronotum, and the pygidium coppery 

 red, and the legs and lower surface dark pinkish brown. The 

 head and pronotum are rather finely but unevenly punctured 

 and rather rugosely at the sides, the elytra coarsely and 

 irrt gularly pitted, and the pygidium finely and closely trans- 

 versely rugulose. 



Although, as already stated, Anoplognathus concinnus, 

 Blackb., is not a distinct species, A. brevicollis, Blackb., 

 treated in Ohaus's recent Catalogue (which is very incom- 

 plete) as a synonym of A. nebulosus, Macl., is quite distinct. 

 1 he elytra do not taper at the extremities, but are furnished 

 with sharp spines at the angles, and the clypeus of the male 

 is longer, broader in front, and almost straight at the sides, 

 where it is not distinctly reflexed. 



The following are undescribed species of this genus in the 

 Museum collection : — 



Anoplognathus pallidus, sp. n. (PI. VIII. figs. 4 & 5.) 



Testaceus, laivissime metallescens, scutello elytrisque pallide flavis, 

 marginibus omnibus (pronoti et elytrorum lateribus exceptis)
