 in Gomera. 



145. Limnebius punctatus, n. sp. 



L. obovatus (antice latus rotundatus, postice gradatim acutior), piceo- 

 niger, obsolete subsiiescens, convexus, grosse et sat parce pubes- 

 cens ; prothorace profunde pnnctato, ad hitera ferrugineo ; elytris 

 vix levins punctatis, versus apicem paulo dilutioribus ; antennis, 

 palpis pedibusque robustis, piceo-ferrugiueis. — Long, corp, lin. |. 



Habitat TenerifFam, in rivulis (prtesertim quodam parvo per sylvam 

 Aguse Garciae fluente) degens. 



The obovate outline of this Limnebius (it being wide and rounded 

 in front, but gradually acuminated behind), in conjunction with its 

 more piceous and obscurely submetallic hue (the sides, moreover, of 

 the prothorax, and the apex of the elytra, being rather brightly ferru- 

 ginous), its convexer, deeply punctured and more coarsely pubescent 

 surface, and its comparatively robust limbs, will at once separate it 

 from the preceding species. Both of these Limnebii, I may add, are 

 perfectly distinct from the Madeiran L. g^'andicollis — which is re- 

 markable, inter alia, for its more elliptic outline (being widened about 

 the middle) and alutaceous sculpture, as well as for the almost equally 

 impressed and remote punctures of its entire upper sui'faee, those 

 of the elytra being perhaps, if anything, somewhat the deepest. The 

 only locality in w^hich I have myself observed the L. punctatus is the 

 little stream which flows through the Agua Garcia of Teneriffe, 

 where it is tolerably common ; it has, however, been taken at Ycod 

 el Alto, in the same island, by Dr. Crotch.

Habitat insulas Canarienses, in Hierro sola adhuc hand detectus. 



The common European L. minutus (which is found also in Madeira 

 and Porto Santo) appears to be universal at the Canaries, Hierro being 

 the only island, out of the seven, in which I do not happen to have 

 observed it. There can, however, I should imagine, be little doubt 

 that it must exist there also ; though the absence of streams in 

 that island, and the consequent scarcity of water, would certainly
