88 Mr. David Sharp on the 



eluding the tarsi, arc yellow ; the apex of the femora a 

 little clouded. 



The only specimen I have seen is probably a male ; if 

 so, the sexual characters are but little evident. 



160. Stenus rufescens, n. sp. (Sec. II. B. Erichson.) 

 Rufo-testaccus, abdomine apice fusco, oculis permagnis, 

 nigris; fortiter punctatus, elytris thorace brevioribus. 

 Long, vix 2 lin. 



This distinct and remarkable species may be placed in 

 the neighbourhood of S. latifrons. It is of narrow 

 build, with very large eyes; it is pale reddish-yellow in 

 colour, the extremity of the hind body and the apical 

 joints of the antennfe infuscate. The head is rather 

 deeply sidcate on each side near the eyes, the central part 

 broad, moderately convex ; the convex part sparingly punc- 

 tured. The thorax is rather broader than long, dilated 

 in fi'ont of the middle, considerably narrowed behind ; it 

 is coarsely punctured, its surface a little uneven. Elytra 

 shorter than the thorax, coarsely punctured, rounded at 

 the sides so as to be distinctly contracted at the shoulders. 

 The hind body is slender, pointed at the extremity, rather 

 sparingly punctured ; the basal segment rather coarsely, 

 the apical ones very finely, punctured. The legs are 

 yellow; the lobes of the foiirth joint of the tarsus are 

 rather long, slender, and closely applied to the following 

 joint, so that on a superficial examination the tarsi might 

 be supposed to be simple. 



In the male the femora are a little thickened, the me- 

 tastemum at the extremity is densely pimctured and deli- 

 cately pubescent; segments 4, 5 and 6 of the hind body are 

 each depressed towards the extremity, the depressed parts 

 more densely and finely pubescent than the other parts ; 

 the 7th segment has a shallow notch at the extremity. 



Two specimens; found under dead leaves on Maiyasama. 



161. Stenus currax, n. sp. (Sec. II. B. Erichson.) 

 Niger, nitidus, fortiter punctatus ; antennis, palpis, pedi- 

 busque pallide testaceis. Long. 2^ lin. 



We have no European species (that I know of) at all 

 closely allied to this ; it is much more slender and shining, 

 and more strongly and sparingly punctured than is S. 

 oculutus. Antennre long and slender, entirely pale yel- 

 low. Palpi also long and slender, very pale yellow. Head
