92 MANDIBULATA. COLEOPTERA. 



Sp. 1. rufifrons. Nigro-picea nitida, capite antennis, pedibus, maculti hume- 

 rali elytrorum apiceque rufis. (Long. corp. 1 — \\ lin.) 



Ips rufifrons. Fabricius. — Steph. Catal. 89. No. 958. 



Shining pitchy-black: head thickly punctulate, dull rufous; with the mouth 

 fuscous: thorax subsinuated behind, the disc punctate: scutellum black: 

 elytra oblong-ovate, convex, slightly punctate-striate, with an ovate rufo- 

 ferruginous spot at the base, and a patch of the same hue at the apex : body 

 with the apex ferruginous: legs and antennae rufo-testaceous, the club of the 

 latter rather pale. 



This species varies considerably in colour, apparently from immaturity : some 



. examples being entirely of an immaculate pale testaceous, and others more or 

 less pitchy or brown, with all intermediate shades. 



Frequently met with in fungi, boleti, &c., within the metro- 

 politan district: also found in Devonshire, Norfolk, Suffolk, &e. 

 "Not unfrequently found among grass in woods (near Swansea)."

Sp. 2. scanicus. Nigra nitida, capite, thorace, elytrorum puncto humerali, an- 

 tennis pedibusque rufis. (Long. corp. if lin.) 

 De. scanicus. Linne. — En. humeralis. Steph. Catal. 89. No. 959. 



Glossy-black: head rufous, thickly punctate: eyes black: thorax shining 

 rufous, the base subsinuated, and slightly margined ; the disc very convex, 

 closely punctulate : scutellum black: elytra oblong-ovate, slightly margined, 

 thickly and finely punctate-striate, shining black, with a small ovate rufous 

 spot on the shoulder : body beneath punctate, black, shining, with the apex 

 reddish : legs and antennse rufous. 



Also variable in colour, dependent upon its state of maturity. 



The rufous thorax, and want of the rufous patch at the apex of the elytra, 

 distinguish this insect from the foregoing. 



Not common ; found within the metropolitan district ; and also 

 in Suffolk and Norfolk. 



Sp. 3. angustata. Angustior, iota pallide testacea immaculata. (Long. corp. 



En. angustata. Kirby MSS.— Steph. Catal. 89. No. 960. 



More elongate and slender than the foregoing species, with the anterior surface 

 pale immaculate testaceous; the legs and antennae rather palest: the elytra 

 sometimes a little clouded with dusky. 



It is possible that this insect may be a mere variety of En. rufifrons, differing 

 in being somewhat more elongate, and narrower in proportion, than that 

 species ; immature specimens of which closely resemble it. 



Found near London, and in Suffolk, in fungi,
