ANlSOTOMIDiE.— -EPHISTEMUS. 167 



De. piceorrhoeus. Mar sham— Steph. Catal. p. 68. No. 720. 



Minute : oblong-ovate, slightly convex, and a little attenuated posteriorly, 

 smooth, shining black ; head and thorax immaculate ; elytra with the apex 

 more or less piceous, or flavescent, their surface impunctate : legs pitchy-red 

 or piceous : antennae pale testaceous, with the club dusky. 



Known by the distinct patch of colour at the apex of the elytra ; by its minute 

 size and the immunity of its elytra : from the next species it differs in the 

 colour of its upper surface and by its pale antennae. 



Found near London ; also in Norfolk, Suffolk, and near Bristol. 



Sp. 27. pulchellus. Ovatus, nitidus, capite thoraceque atris, elytris fusco-cas- 



taneis, apicibus dilutioribus, pedibus antennisque rufis. (Long. corp. ^ lin.) 

 De. pulchellus. Marsham.— Steph. Catal. p. 68. No. 721. 



Very minute : ovate, glossy ; the head and thorax black, with the anterior mar- 

 gin of the latter slightly castaneous ; elytra of a castaneous-brown, with the 

 apex paler ; smooth, not striated : legs and antennae pale rufous. 



The smallest species of the genus ; differs from the foregoing by the deeper 

 colour of its antennae, smaller size, and dissimilar colouring, the diluted patch 

 at the apex of the elytra being small, and not distinctly indicated, as in that 

 insect : from the following it differs by its pale antennae, and by wanting the 

 striae on the elytra. 



My specimens of this minute insect I obtained from the Mar- 

 shamian cabinet. 



Sp. 28. nitens. Oblongiusculus, niger, nitidus, elytrorum apicibus pallidis, pe- 

 dibus ferrugineis, antennis nigris, elytris substriatis. (Long. corp. § lin.) 

 De. nitens. Marsham. — Steph. Catal. p. 68. No. 722. 



Minute; rather oblong, black, shining: head and thorax immaculate: elytra 



faintly striated, pitchy-black, with the apex paler : legs ferruginous : antennae 



dusky or black. 

 The small bulk, deep shining black body, with faintly striated, pale tipped 



elytra, ferruginous legs, and dusky antennae, sufficiently distinguish this 



species from all the foregoing. 



Found in Suffolk and Norfolk. 



Genus CIX. — Ephistemus,. Westwood MSS. 



Palpi not filiform; maxillary with the basal joint robust, the terminal elongate, 

 subulate; labial very short: mandibles rather prominent, with the apex 

 entire. Antenna; rather elongate, approximating at the base, the two basal 

 joints robust, the third more slender than, but not so long as, the second, 

 the five following very short, globose, the remainder forming a triarticulate 

 club, with the tenninal joint obtuse: head minute: thorax slightly gibbous,
