131 



rower, somewhat flat above, with the apex emarginate : eyes small, rounded, 

 but little prominent : thorax gently transverse, with the sides slightly rounded: 

 body oblong-ovate, winged: elytra large, oblong-ovate, setose, convex above, 

 especially behind, with the apex slightly acuminated : legs rather long, slender: 

 femora strongly clavate, and shghtly dentate : tibioe straight, with the apex 

 unarmed. 



Sciaphilus differs from Strophosomus and the following genus, 

 not only by having the elytra free, and in possessing wings, but 

 by the texture and form of body, dissimilarity in the structure of 

 the antennae, dentate femora, &c. 



Sp. 1. muricatus. Fusco-cinereus, hispidus, dense cinereo-squamosus, antennis 



pedibusque fusco-ferrugineis. (Long. corp. 2^—3 lin.) 

 Cu. muricatus, Fabricius. — Sc. muricatus. Steph. Catal. 176. No. 1799. 



Fuscous-ash, densely clothed with shining ashy scales : head somewhat rugu- 

 lose: rostrum with the apex glabrous and black: thorax cinereous, with the 

 sides and a narrower dorsal line whitish : scutellum piceous : elytra pale rufo- 

 piceous, ^vmctate-striate, the interstices rather smooth, more or less distinctly 

 varied with ashy and fuscescent scales, and each with a series of compact 

 ashy-brown hairs : legs elongate, generally rufo-ferruginous, sometimes with 

 the femora fuscescent : antennae rufescent, with the club dusky. 



Far from uncommon in the woods about London, especially at 

 Darenth, in sliady places : also in Somersetshire. " Not uncommon 

 (near Swansea)."—!.. W. Dillwijn, Esq. " Black Hall Wood."—

Sp. 2. asperatus. Obscure-cinereus,fusco-maculatis, thorace lineis tribus cine- 



rascentibus, antennis pedibusque rufescentibus. (Long. corp. 3 lin.) 

 Cu. asperatus. Fabricius.— Sc. asperaXus. Steph. Catal. 176. No. WOO. 



Dull cinereous, clouded with fuscous : head immaculate: thorax fuscous, with 

 three cinerascent hues, one dorsal, the others lateral and broader: elytra 

 faintly striated, the interstices spotted with fuscous, and having short scattered 

 hairs or sets : antenna; and legs reddish. 



Although darker in colour than the preceding, the antenna and legs are paler: 

 the insect may nevertheless be only a variety. 



Found occasionally within the metropolitan district. " On 

 willows and on Crwmlyn-burrows, not common."—/.. W. Dillwyn, 

 Esq. 



Sp. 3. pusillus. Griseo-cinereus, hand variegatus, elytris tenus striatis, inter- 



stitiis suhhispidis, antennis rufo-piceis. (Long. corp. Ij hn.)
