TACHYPORIU.E. BOLITOBIUS. 171 



Short, glossy, rufescent, smooth^ and glabrous: head suborbiculate, jojceowj : 

 thorax testaceous : elT/ira the same^ each with four strice composed of very- 

 minute punctures : abdomen scarcely longer than the elytra, fuscescent : legs 

 testaceous^ the posterior tarsi as long as the tibiae : antennce piceous, with the 

 base testaceous, the apical joint obturbinate. 



Found in Norfolk and in Suifolk; and I beKeve also near 

 London. 



Sp. 10. punctus. Oblongus, rufo-testaceis, nitidus, glaher, capite nigro, peciore, 

 abdomine elytrorumque tristriatarum margine fusco-piceis. (Long. corp. 

 1| lin.) 



Ta. punctus. Gravenhorst. — Is. punctus. Steph. Catal. 269. No. 2787. 



Oblong, rufo-testaceous, shining, glabrous : liead rounded, black, with the 

 mouth and palpi rufo-testaceous : thorax rufous, impunctate ; breast 

 fuscescent: elytra shining, rufo-testaceous, with the lateral margin dusky, 

 each with three punctured strice : abdomen tusco-piceous, with the apex rufes- 

 cent : legs rufous : antennae iwsco-piceous, with the base and the terminal joint, 

 which is ovate-acuminate, testaceous. 



Taken near London, and in SuiFolk. 



Genus CCCCXCVL— Bolitobius, Leach MSS. 



Antennas moderate, 11-jointed, very slender at the base, distinctly incrassated 

 towards the apex, the basal joint elongate, slightly bent and subclavate, 

 second and third shorter, of nearly equal length, slender, subconic ; six fol- 

 lowing shorter and stouter, increasing to the apex ; the terminal one oblong- 

 ovate. Palpi rather long, filiform, maxillary with the terminal joint equal 

 in length to the preceding, and subacuminated : head small, sometimes 

 slightly elongate : thorax transverse, with the hinder angles rounded : body 

 slender, elongate, attenuated at both ends : elytra for the most part with 

 obsolete striae : abdomen conic, setose behind : legs moderate ; tibiae spinose, 

 with long spurs at the apex of the four posterior. 



Bolitobius agrees with Megacromis in having the palpi filiform, 

 but they are very slender, and longer in proportion ; from that 

 genus, however, the elongate head and gracility of the antennae, 

 the terminal joint of which is not elongated, as well as the livehness 

 of the colouring, and the generally maculated elytra, readily distin- 

 guish it. The species almost universally reside in boleti and fungi. 



Sp. 1. lunulatus. Rifus, nitidus, capite, pectore ahdominisque ajiice nigris, 

 elyiris nigro-crp.ruleis , basi iota, margineque apicis rufo-testaceis. (Long, 

 corp. 2 — 3 lin.)
