132 MANDIBULATA. COLEOPTERA. 



in collecting notes for this work and for my Catalogue, the Rev. W. 

 Kirby informed me that this singular insect had been captured in 

 England by his colleague W. Spence, Esq. ; but of its locality he 

 was not aware. 



Genus CLXXVI.^Trinodes, Megerle. 



Antennae longer than the thorax, beneath which are no grooves for their recep- 

 tion, the two basal joints very robust, subglobose; the six following slender, 

 gradually diminishing in length, the eighth being shortest and transverse, the 

 remainder forming a triarticulate club, of which the basal joint is smallest, 

 the terminal very large, trigonate. Palpi very short, filiform : head obtuse, 

 deflexed : eyes small : thorax short, anteriorly truncate, and narrowed ; the 

 base as broad again and distinctly trilobed : scutellum moderate, triangular : 

 elytra large, ovate, slightly convex ; the shoulders gibbous, and, with the 

 head and thorax above, clothed with erect elongate hairs, without any inter- 

 mixture of scales: legs slender, pilose: tarsi elongate; the four basal joints 

 equal. 



Trinodes, a genus whose characters have not hitherto been 

 defined, was established by Megerle for the reception of the An- 

 threnus hirtus of Fabricius; an insect differing so considerably 

 from the type of the genus last mentioned as to justify its separa- 

 tion : its densely pilose body, the hairs of which are erect and 

 comparatively very long ; and the length of its antennae, which have 

 no grooves beneath the sides of the thorax for their reception ; 

 sufficiently discriminate it, without descending to other less obvious 

 characters : — the insect, moreover, inhabits decayed wood. 



Sp. 1. hirtus. Niger aut griseo-testaceus, nitidus, supra dense hirtus, antennis 



pedibusque luteis. (Long. corp. \\ — 1^ lin.) 

 Anth. hirtus. Fabricius. — Tr. hirtus. Steph. Catal. 97. No. 1025. 



Black or griseo-testaceous, shining, with a translucent appearance: head punc- 

 tate: thorax with the disc anteriorly convex, with an impression between 

 the base and sides: elytra faintly punctate, shining pitchy-black, very 

 pilose : body beneath rufo-piceous, slightly pubescent : legs luteo-testaceous : 

 antennce pale luteous. 



Sometimes rather paler in colour. 



The only examples I have seen of this insect were captured, I 

 believe, near Exeter, by W. Spence, Esq., who kindly forwarded a 

 pair for my cabinet.
