328 CLAVicoRNiA. [Henoftcus. 



punctured ; legs ferruginous ; the elytra are usually obscurely brownish 

 towards apex ; the female appears to be rather broader than the male, 

 Avhich has the sides of the elytra less rounded. L. 2 mm. 



On the male blossoms of the sallow, &c. ; very rare; London district, Forest Hill, 

 one example found by Mr. Marsh crawling on a wall ; Nortliumberland district, in a 

 wood near Washington, very rare (Bold) ; Scothnid, Tay district, ilanuoch, very rare 

 (Sharp). 



PARAMECOSOMA, Curtis. 



This genus, as constituted in the Munich catalogue, is made up of 

 the three genera Paramecosoma, Micraynlje, and Henoticus ; in its 

 strict sense it appears only to contain four or five species from Europe 

 and North America ; it is distinguished from Cryptopha(jus and Heno- 

 ticus by having all the tarsi of the male 5-jointed, and from Micramhe 

 by having the sides of the thorax not denticulate ; our single species is 

 not uncommon in some localities in England, but appears to be much 

 commoner in Scotland. 



P. melanocephalum, Herbst. Oblong, slightly convex, clothed 

 with rather fine pale pubescence, brownish or brownish-testaceous, often 

 almost reddish-testaceous, with the head and thorax black ; antennae 

 long and rather slender, reddish ; thorax much narrower at base than 

 elytra, a third broader than long, anterior angles simple, side margins 

 well marked, not denticulate, but with two projections in middle, very 

 thickly and rather deeply punctured ; elytra rather long, distinctly 

 punctured almost in rows, the punctuation becoming obsolete towards 

 apex ; legs slender, reddish-testaceous. L. 1| mm. 



On sallows; also in flood refuse; local; London district, rare, Chatham, Walton- 

 on-Thames; Glanvilles Wootton ; Welshpool; Cromer (in company with Formica 

 fuUgiiwsa) ; Solihull ; Salford Priors ; Repton (not uncommon in flood refuse) ; 

 Liverpool and Manchester districts; Northumberland district, Hartford Bridge, 

 Briar Dene, and on the Irthing (in tufts of grass left on the bushes by floods) ; Scot- 

 land, in flood refuse on the banks of rivers, abundant as far north as the Moray 

 district and probably general. 



This species may be easily known by its coloxtr, which is very bright 

 when it is alive. 



ATOMARIINA. 



This tribe, like the preceding, contains a considerable number of 

 species, but the genera have not been defined with certainty. Cmnoscclis, 

 Tboms., seems without doubt to be distinct, but the characters assigned 

 for Ancliicera, Thoms., appear to be scarcely sufficient to warrant its 

 separation as a distinct genus ; the species are easily distinguished from 

 the Cryptophagina by the position of the antennae, which are situated on 

 the forehead between the eyes, and are approximate ; the sides of the 

 thorax are more or less distinctly margined, but are never denticulate.
