(EDEMERID>E. LYMEXYLON — CALOPUS. 61 



Gyllenhal's Conopalpus flavicoUis is said to be pitchy-brown where the above 

 is blacky and to have the base and lateral margin of the elytra to the middle 

 rufous. It probably may be an immature state thereof, as Gyllenhal had 

 seen only a single example. 



Found in Cumberland by Mr. Weaver in August, 1827 ; about 

 three specimens had previously been taken in England, but I am not 

 aware of their exact locality. 



Genus CCCCLXV. — Lymexylon, Fabricius. 



Antennce 11-jointed, pilose, simple; subfusiform, the basal and apical joints 

 most slender, the last suddenly attenuated in the middle. Palpi dissimilar 

 in the sexes, maxillary largest, with the terminal joint distinctly incrassate, 

 ovate-truncate in the female ; pendulous and branched in the males ; labial 

 approximating in the males, remote in the females : mandibles short, stout, 

 sinuated within in the females : head vertical, suborbicular, with a short 

 neck : eyes pubescent : thorax oblong, subcylindric : elytra abbreviated, 

 subulate, divaricating at the apex : body very much elongate, linear-cylin- 

 dric : abdomen very long, ovate, and depressed at the apex : legs slender : 

 femora compressed ; tihicB and tarsi simple, the last all 5-jointed. 



This singular genus of insects unquestionably belongs to this 

 family, as placed in my Catalogue, notwithstanding it possesses five 

 joints to all the tarsi, its habit and general structure evidently point- 



Genus CCCCLXIV.— Calopus, Payhull. 



Antennce 11-jointed, filiform, rather deeply serrated, the second joint acuminate, 

 terminal elongate, slender, simple. Falpi unequal ; maxillary elongate, 

 porrect, with the terminal joint subsecuriform ; labial with the same joint 

 thickened and ovate : mandibles bidentate at the apex ; body elongate, nar- 

 row ; head and thorax rather narrower than the abdomen : eyes large, lunate : 

 elytra linear : legs slender ; femora compressed ; tibice with very short spurs ; 

 tarsi with the terminal joint bifid. 



^Sp. 1. serraticornis. Brunneus, pubescens, punctulatus, oculis nigricaniibus, 



elytris subruguloso-pundatis, lineis aliquot elevafis, vix distinguendis. 

 Ce. serraticornis. Linne. — Turton. (!) — Ca. serraticornis. Steph. Catal. 252. 



No. 2505. 

 Pale brown, pubescent, punctulated : eyes dusky : thorax a little unequal, 



with the sides slightly dilated anteriorly, rounded : elytra somewhat rugu- 



lose-punctate, with several very obscure elevated lines. 



Turton indicates this as British.
