60 Mr. David Sharp on the 
subtus niger, pedlbus testacels, femorum margine posteriore 
nigricante. Long. 2\\ lat. 1^ lin. 
Maxillary palpi yellow ; the apex of the last joint slightly 
infuscate. Head closely and rather finely punctured, the 
front part yellow, the hind part black. Thorax yellowish, 
the disc a little clouded ; it is rather finely and closely 
punctured, and has near each side a curved irregidar patch 
of larger punctures. Elytra yellowish, not so densely 
punctured as the thorax, rather strongly striated, the 
sutural stria not reaching to the base, and the two or three 
next to it extremely indistinct at the base ; from the third 
to the ninth each alternate interstice bears some larger 
punctures. The underside is black, the legs yellow ; the 
femora darker behind, pubescent beneath, except at the 
extremity of each ; hind tarsi long and slender ; carina of 
the mesosternum largely developed, its front angle acute. 
A single specimen only of this species has been taken 
by Mr. Lewis at Nagasaki ; this is the only Philhydrus 
I have ever seen Avith distinctly striated elytra, though 
I know several species oi Helo chares sculptured in that way. 
36. Helocharea striatus, n. sp. Ovalis, minus depressus, 
rufo-testaceus, capite nigricante macula utrinque rufo- 
testacea ; crebre fortiterque punctatus, elytris fortiter punc- 
tato-striatis ; subtus obscure rufescens, tibiis tarsisque tes- 
taceis. Long. 2^ lin. ; lat. 1^ lin. 
Maxillary palpi entirely yellow, considerably shorter 
than in H. lividus, but similarly formed. Head blackish, 
yellow on each side in fi-ont of the eyes, coarsely and rather 
closely punctvu'ed. Thorax with the punctuation similar 
to that of the head, the lateral margin coarser behind than 
in front. Elytra rather less strongly punctured than the 
head and thorax, each with ten strife of rather deeply im- 
pressed punctures, a short abbreviated row of punctures 
between the scutellum and first stria ; the strife do not ex- 
tend quite to the outside, but leave a distinct margin much 
directed outwards. The Under surface is pubescent and 
pitchy red ; the elytra greatly overlap the hind body ; the 
mesosternum has a slightly elevated tubercle in front. The 
tibia3 and tarsi are yellow. 
I have seen but a single specimen of this very distinct 
and interesting species ; it was found by Mr. Lewis at 
Nagasaki. 
I possess allied species from Australia and Cochin China.
