that genua ; it differs in several respects, more especially in 

 the great separation of the hind legs and the very dependent 

 front of the prosternum. The form is different from that of 

 Stenelmis, and the sculpture is not similar to that of any 

 other Elmid known ; the eyes, too, are much smaller than in 

 StenelmiSj and the terminal joint of the maxillary palpus more 

 slender. 



Leptelmis gracilis, n. sp. 



Minus parallelus, niger, antennarum basi pedibusque piceis ; pro- 

 thorace valde iucequali, anterius profande transversim depresso ; 

 elytris subovatis, dense seriatim foveolatis. 



Long. 2^ millim. 



Antennae very slender, black externally, piceous towards 

 the base, the basal two joints nearly yellow. Thorax 

 narrow in front, with a very broad and deep transverse 

 depression extending across it near the front ; on the disk 

 with two oblique depressions convergent behind, the spaces 

 between them nodular ly elevated. Elytra much broader than 

 the thorax, broader behind, densely covered with deep fovefB 

 arranged in series. Legs slender, very long. 



Tokio : one mutilated example. Discovered by Mr. Tanaka 

 of that city.

" St. elongatus, niger, antennis basi unguiculisque rufis, protborace 

 ante medium foveolato utrinque obsolete impresso, elytris punc- 

 tato-striatis, interstitio secundo, quinto septimoque carinatis. 

 Long. 3'3 millim." 



Has been found in a swiftly running brook in the neigh- 

 bourhood of Hiogo. 



Georyssus canalifer, n. sp. 



Brevis, niger, elytris fortiter profundeque seriatim punctatis ; pro- 

 tborace anterius sculpturato, medio usque ad basin canaliculato. 

 Long. 2 millim. 



Thorax with some irregular elevations on the front part, the 

 lateral margins crenate ; along each side a series of tine ele- 

 vations extending to the base, and on the middle an elongate 

 channel. Elytra shining, with regular series of very coarse 

 punctures. 



This is allied to G.pygmceus, but is larger and more coarsely
