yellow clouded with brown, Jind with a number of narrow brown 

 punctured strias. 



This may perhaps be a Bernsus. I have not been able to 

 examine the species satisfactorily. 



Hydrobaticus. n. gen. 



But for the total absence of any tubercle or carina on the 

 mesosternum, the two species I describe under this genus, might 

 be almost as well placed with Pliilliyclrus. They are also, how- 

 ever, of a more broadly ovate and flat form. As i-egards the 

 antennsB and palpi they exactly correspond with Philhydrus. 



189.— Hydrobaticus tristis. n. sp. 



Length 2 1 lines. 

 Flat, opaque, coarsely punctured and of a dull reddish brown 

 colour clouded with black. Head rather impressed along the 

 suture of the epistome, with the labrum black. Thorax consi- 

 derably broader than the length, slightly rounded on the sides 

 and not broader behind than in front, with the anterior angles 

 very round, the posterior angles obtuse, and the base truncate. 

 Elytra broader than the tliorax, broadly rounded at the apex, 

 and covered with numerous coarse punctured striaa, and with the 

 disk of a much darker colour tlian the sides. 



190. — Hydrobaticus luridus. n. sp. 

 Length 2 lines. 

 Of the same form and sculpture as the last described sjiecies, 

 differing only in size, and in being entirely of a pale lurid colour, 

 with the exception of the labrum and back of the head which are 

 black. In both this and the former species the scutellum is 

 smaller and less elongate than is usual in Philhydrus. 



I regret that I am unable from paucity of specimens to make 

 a proper examination of either of the species. 



Hygrotrophus. n. gen. 

 Head large, much prolonged in fi'ont of the eyes, and more or
