Dr. D. Sharp on new Japanese Goleoptera. 243 



Parnus, but bj the structure of its antennsB it is allied rather to 

 the latter genus ; its nearest described ally is Elmoparnus^ from 

 which it differs in so many details that it is better to treat the 

 two as distinct genera. The body is oval, with elongate legs 

 and very long tarsi. The antennte are very short; the first two 

 joints are of a different form from the rest, and serve to close 

 the cavity into which the antennge are deflexed in repose ; the 

 other joints are short and broad, and form a small mass acu- 

 minate at the extremity. The head, the sides of the thorax, 

 and the whole of the elytra have a peculiar silky opacity, such 

 as is seen in many Elraides ; tlje under surface is entirely 

 covered with the peculiar tomeutum for bearing air, except 

 the middle of the metasternum and prosternum, and here 

 there is a large smooth space. The maxillary palpi are 

 rather long, the terminal joint slender, oval, three or four 

 times as long as the preceding j the prosternum is elongate, 

 and extends further forwards than the front of the pronotum ; 

 the front cox^ are small, very widely separated; and the 

 middle legs are even more widely separated. There is no 

 trace of striae or impressions on the thorax. 



Elmomorphus brevicornis, n. sp. 



Niger, supra subaenescens, prothorace nitido, for titer punctate, tarsis, 



antennis oreque rufis ; Bubtus tomento griseseento vestitus. 

 Long. 3| millim. 



Thorax much narrowed in front, anterior angles greatly 

 produced, very acute, the base lobed in the middle, the lobe 

 emarginate in adaptation to the large scutellum, hind angles 

 acute, the surface coarsely punctate, quite shining in the 

 middle, dull at the sides. Scutellum smooth, shining. Elytra 

 dull, with an extremely minute setosity, with regular series of 

 coarse punctures that become quite obsolete at the extremity. 

 Tibias finely pubescent internally towards the apex. 



Kob^, South Japan : two specimens found by Mr. G. Lewis 

 in May 1871, and recorded in his Catalogue of Japanese 

 Goleoptera as "862. Helichiis, spec?" Helichus, Er., is, 

 however,' as I have shown elsewhere, the same as Dryops,
