Micramhe.] clavicoknia. 327 



I. Sise smaller, pubescence longer and thicker, anterior angles 



of thorax produced into a tooth behind M. VINI, Pawz. 



II. Size larger, pubescence sliorter and less thick, anterior 

 angles of thorax not produced into a tooth behind . . . M. abietis, Pai^Jc. 



BI. vlnl, Panz. {Paramecosoma pilusula, Er. ; Cryptophagus vini, 

 Er. et auct.). Reddish-testaceous or light ferruginous, slightly convex, 

 clothed with rather long and tJiick pale pubescence ; antennae rather 

 long; head triangular, eyes black, prominent; thorax in front almost 

 as broad as elytra but considerably narrowed behind, strongly transverse, 

 anterior angles callosely reflexed and produced in a more or less evident 

 tooth behind, sides finely serrate, posterior angles blunt, punctuation 

 thick and deep ; elytra more or less oval, thickly but rather coarsely 

 and deeply punctured, the punctures becoming much finer towards apex ; 

 legs slender, testaceous. L. 1| mm. 



On flowers of gorse, broom, &c. ; occasionally, but not often, in vegetable refuse; 

 very abundant and widely distributed throughout the kingdom. 



• IMC. abietis, Payk. Closely allied to the preceding, but distinguished 

 by its rather larger size, shorter and less thick pubescence, and the fact 

 that the anterior angles of the thorax are less dilated and not produced 

 into a tooth behind ; the elytra also are more finely and closely punctured. 

 L. 1| mm. 



On pine trees ; Micklebam (W. G. Blatch) ; Guildford (E. Capron) ; the habitat 

 of this species appears to be different from that of the preceding, but, unless I am 

 mistaken, I have found M. vini on low-growing firs. 



KSNOTZCUS, Thomson. 



This genus was founded by Thomson for the reception of the insect 

 known as Criiptophagtis serratus, or better as Paramecosoma serrata ; 

 from the latter genus it differs by having the posterior tarsi of the male 

 4-jointed instead of 5-jointed ; and from the former by having the 

 penultimate joint of the tarsi abruptly shorter and narrower than the 

 preceding instead of equal to it as in Cryptopliagus ; in this respect it 

 resembles Micramhe, from which, however, it diff'ers in not having the 

 anterior angles of the thorax callosely reflexed ; it is one of our rarest 

 British species. 



H. serratus, Gyll. {Cryptophagus serratus, Gyll. ; Paramecosoma 

 serrata, auct.). Oblong, nigro-piceous, rather shining, clothed with long 

 and rather coarse pubescence ; antennae moderately long, ferruginous, 

 Avith well-marked club ; thorax a little narrower at base than elytra, 

 transverse, feebly rounded at sides, anterior angles not callosely reflexed, 

 posterior angles right angles, deeply and rather coarsely punctured, 

 less closely on disc than on sides, side margins strongly and evenly 

 serrate ; elytra subparallel, with sides slightly rounded, rather coarsely
