502 CANARIAN COLEOPTERA. 



interstices convex and minutely (though sharply and rather spa- 

 ringly) punctulated. Its head and prothorax are likewise sharply, 

 but more closely and coarsely, punctured. 



Genus 285. BOROMORPHUS. 

 Wollaston, Ins. Mad 492. tab. xi. f. 9 (1854). 



751. Boromorphus parvus, n. sp. 



B. angusto-subcyHndricus, subopacus, parce sed grosse fulvescenti- 

 cinereo-ijubeseens, fusco-piceus ; capite prothoraceque saepius paulo 

 rufescentioribus, densissime rugoso-punctatis (punctis longitudina- 

 liter subconfluentibus), hoc elongato-quadrato (postice vix ang-us- 

 tiore); elytris subparallelis, minute et levissime pimctulatis (punctis 

 indistinctis et vix longitudinaliter dispositis) ; antennis pedibusque 

 rufo-testaceis. — Long. corp. lin. 1-lj. 



Obs. — Species quam B. tagenioides Lucas (=B. madene Woll.) 

 minor ac magis eylindrica, elytris antice et prothorace postice mi- 

 nus angustatis, oculis minoribus, puncturji in capite prothoraceque 

 densiore ac magis rugosa, sed in elytris subtiliore ac le\aore (sc. le- 

 vissima), antennis gracilioribus, pedibus brevioribus sed femoribus 

 forsan sublatioribus. 



Habitat in montibus Lanzarotse, Fuerteventurae et TenerifFae, raris- 

 simus. 



This little Boromorphus seems to occiu' at rather lofty altitudes in 

 the eastern and central portions of the archipelago, and is evidently 

 very scarce. I have taken it from beneath small stones in the cre- 

 vices of the rocks on the top of one of the highest hills about a mile 

 to the south of Haria, in the north of Lanzarote ; as well as on the 

 summit of the Atalaya, above the Eio Palmas, in Fuerteventura — 

 the most elevated mountain in that island : and a single specimen 

 was captured by Dr. Crotch, during the spring of 1862, in TenerifFe 

 — I believe at, or near, Ycod el Alto. It is exceedingly distinct from 

 the B. tagenioides, of Mediterranean latitudes and Madeira, being 

 smaller and more parallel, or cylindric (the bases of the prothorax 

 and elytra being, each of them, less narrowed, or drawn in), with the 

 punctation of its head and prothorax denser and more rugose, whilst 

 that of the elytra is both finer and lighter (the punctules being very 

 obscure even under a lens), with its eyes smaller, its antennae slen- 

 derer, and its legs shorter.
