476 Mr. David Sharp's revision of the 



A very mutilated example, deprived of its palpi, some 

 of the legs, and all the tarsi, except a portion of one of 

 the posterior pair, was sent me several years ago by 

 Captain Broun, I believe from Tairua, as No. 10 ; not- 

 withstanding this I cannot reconcile the insect with any 

 of the descriptions in his * Manual of New Zealand 

 Coleoptera ' ; Ci/donotum Jiavicornc would appear to be 

 somewhat allied to it, and may probably belong to 

 Hijdrostygnus, but the characters " rather short, epistome 

 truncate in front, with rather prominent eyes," are 

 expressions which it would appear almost impossible an 

 entomologist could apply to this species. 



Hydrostygnus linsi, n. s. 

 Ovalis, latns, niger, sat nitidus, antennis palpisque rufis, tarsis 

 piceis ; corpore supra deuse punctate, elytrisque prteterca seriebus 

 decern punctorum majorum, seriebus interuis oLsoletescentibus 

 sed suturali apiceni versus in striam coutiuuata ; tibiis crassis rude 

 scabrosis. Long. 7^ mm., lat. 5 mm. 



This very remarkable Hydrophilid is readily identi- 

 fiable by the thick, densely scabrous, middle and hind 

 tibiae ; the punctures of the external series of the elytra 

 are remarkably large and definite, but give rise to no 

 appearance of striation ; the sutural series is scarcely 

 distinguishable in front, but behind forms a fine well- 

 marked stria. The mesosternal portion of the pectoral 

 prominence is rather large, quite as long as it is broad, 

 and the middle legs are comparatively sHghtly separated ; 

 the hind tarsi are quite laxly articulated, and are fur- 

 nished with long bushy pubescence beneath. 



We are indebted to Mr. Lins, of Mouri Creek, about 

 sixteen miles from Greymouth, for the discovery of this 

 and some other remarkable species of Coleoptera. Mr. 

 Lins is placed in a district which certainly supplies 

 some remarkable insects, and it will be a great benefit 

 to Science if he can devote some time to their research.
