ENG1J0JE. — BIPHYLLUS. 87 



Sp. 6. pubescens. Nig?'o-piceus, pubescens, elytris dilutioribus hasi fascia oh- 

 soletd pone medium apiceque ferrugineis ; antennarum capitulo distincte et 

 subabruptH quadriarticulato. (Long. corp. 2 lin.) 



My. pubescens. Steph. Catal. 88. No. 948. 



Pitchy-black, pubescent, mouth testaceous: thorax rather thickly clothed with a 

 golden pubescence, finely punctate, with a fovea on each side at the base : 

 elytra paler, with an obscure undefined ferruginous fascia at the base, an ob- 

 solete abbreviated one beyond the middle, and the apex and lateral margins 

 rather bright ferruginous : the legs and antenna? ferruginous, the latter with 

 the four first joints forming a distinct somewhat abrupt club. 



This may be the Mycetoplagus tetratoma of De Jean, but as that insect has 

 not yet been described, I am not certain upon the point : — the distinct club 

 of the antennae, of which the four last joints are somewhat abruptly larger 

 than the rest, would suggest that appellation. 



Of this very distinct species I have hitherto seen but the one 

 specimen which is in my own collection : it was taken about five 

 years since near Portsmouth. 



Genus CXLIX. — Biphyllus, De Jean. 



Antennae shorter than the thorax, the basal joint large, robust, obconic, the second 

 rather less, also obconic : the seven following somewhat slender, very bhort, 

 slightly increasing to the end: the tenth very large, perfoliate, obconic, 

 truncate : the last scarcely so broad as the tenth, rounded. Palpi short ; the 

 last joint slightly attenuated, truncate: head small, depressed: eyes small, 

 slightly prominent : thorax rather narrowed anteriorly, subsinuated on the 

 hinder margin, the lateral margins slightly rounded, subcrenate, ciliated, with 

 a longitudinal elevated line on each side parallel with the edge : scutellum 

 rounded : body oblong-ovate, slightly convex : elytra entire : legs rather short; 

 tarsi quadriarticulate ? 



Biphyllus is distinguished from all the preceding genera of this 

 family and all the following, excepting Bitoma, Lyctus, and Xylo- 

 tragus, by the biarticulate club of the antennse, but from the latter 

 it may be known by the brevity and convexity of the body, com- 

 bined with the elevated costa parallel witb the lateral margin of 

 the thorax. 



Sp. 1. lunatus. Plate xvii. f. 3. — Nigro-piceus, pubescens, elytris punctata* 



striatis, lunula duplici dorsali cinereo-pubescente. (Long. corp. 1^ — lj lin.) 

 De. lunatus. Fabricius P—By. Sphseria?. Steph. Catal. 88. No. 949. 



Pitchy, or deep, black ; slightly pubescent : head finely punctate, with the mouth 

 pale testaceous : eyes brownish : thorax slightly emarginate anteriorly, a little 

 eonvex, and shining and somewhat thickly punctate: scutellum piceous:
