CAXARIAN COr.EOPTERA. 593 



Although extremely rare, this Sieims is widely spread over the 

 archipelago — occurring in moist, sylvan (and subsylvan) spots of 

 intermediate and rather lofty elevations, and having been detected 

 in all the islands except Lanzarote and Fuerteventura (where it pro- 

 bably does not exist). I have taken it in Grand Canary, TcneriiFe, 

 Palma, and Hierro ; and four specimens were captured in Gomera 

 (" in the laurel-woods above Hermigua") by Dr. Crotch. My Tene- 

 riffim examples are from the sylvan mountains above Taganana, Las 

 Mercedes, the Agua Garcia, the Agua Mansa, and Ycod el Alto. It 

 may at once be known by its slightly shining, (vneons and most 

 coarsely sculjitured surface — the head, prothorax, and elytra (the last 

 of which are much abbreviated) being very deeply and roughly punc- 

 tured. Its antennae are rather long and slender ; and their basal 

 portion, together with the palpi and legs, are pale diluted- testaceous. 



(Subfam. VIII. OXYTELIDES.) 



Genus 332. BLEDIUS. 

 (Leach) Steplions, III. Brit. Eat. v. 307 (1832). 



910. Bledius januvianus, n. sp. 

 B. capite prothoraceque grosse alutaceis, subopacis, illo nigro utrin- 

 que cornu sublauielliformi (pnxj.sertim in maribus) instructo, hoc 

 piceo lato transverso-subquadrato canaliculato parce profundeque 

 punctate ; elytris densius sed minus profunde punctatis, testaceis 

 sed versus suturam latissime ac suffuse nebulosis ; abdomine nigro, 

 apice paulo dilutiore ; antennis rufo-ferrugineis, basi clarioribus ; 

 pedibus testaceis. — Long. corp. lin. 3-3^. 



Habitat Lanzarotam, rarissime : ad marginem lacus ejus salini 

 " Januvio " dicti, Martio a.d. 1859, exemplaria quinque coUegi. 



I am exceedingly doubtful whether this Bledius should be regarded 

 as more than a greatly developed state of the Euroj)ean B. hicornis 

 — with which in colour, sculpture, and general fades it is almost 

 coincident. It seems indeed to differ merely (so far as I can detect) 

 in being considerably larger, with its eyes stiU more prominent, and 

 its prothorax a little wider and more coarsely punctured. Its com- 

 paratively large size and testaceous elytra, combined with its simple 

 (or M/icornuted) prothorax in both sexes, and the erect, compressed, 

 somewhat lameUiform horn with which either side of its forehead is 

 furnished, will at once distinguish it from the two following species. 

 It appears to be exceedingly rare, and peculiar to saline spots — the 

 few specimens which I have seen having been captured by myself 

 at the edges of the salt lake of Januvio, adjoining the south-western 

 coast of Lanzarote, on the 2Gth of March 1859.
