466 Four new species of the Coleopterus Family 



genera belonging to Westwood's 2nd Section of the Paus- 

 sidce, and distinguished by the curious tomentum-shaped 

 clava of their antennae, which consist apparently of six 

 joints, of which the five terminal ones are soldered together 

 so as to form a continuous joint. However, as two out of 

 the three specimens which I had the good fortune to cap- 

 ture, are by this time in the hands of Mr. Westwood and 

 the Rev. F. W. Hope, and as the former gentleman has 

 probably described it, I shall refrain from giving a fully de- 

 tailed account of the insect, which is likely to constitute the 

 type of a new genus in the family, forming the Asiatic re- 

 presentative of the African genus Pentaplatarthrus. 



The trophi approximate the form to Pentaplatarthrus, the 

 last joint of the labial palpi being clavate and obliquely 

 truncated, but the labial palpi do not exceed in length the 

 maxillaries, as they do in Pentaplatarthrus, The two last 

 joints of the maxillaries are very small, and are bent down 

 like a hook, as in Ceratoderus. 



The thorax is formed upon the model of the first division 

 of the genus Paussus, being apparently bipartite, the basal 

 portion being also the larger, and the anterior one wider 

 and angulated at the sides, but provided with a small tuber- 

 cle on each side below the angle, and not spined as in Pen- 

 taplatarthrus. 



The club of the antennae is narrower at its base than in 

 Ceratoderus, and is deficient in the tooth or lingula observa- 

 ble at the base of the 2nd joint in that genus ; the edges also 

 form an overlapping scale at the posterior junction of the 

 joints of the clava. The head is like that of Ceratoderus, 

 and the antennae are not based on a ball, as they are in 

 Pentaplatarthrus. 



The Beetle is of a light rufous chestnut colour, with an irre- 

 gular black triangular patch including a chestnut spot poste- 

 riorly, on either side of the elytra, and within a final one at 

 the suture. The elytra are rough and wrinkled, deflexed
