Cryptophagus.] CLAVICORNIA. 315 



1. Upper surface unicolorous reddish-brown. 



A. Elytra less oval, pubescence shorter, punctua- 



tion closer C. piLOSUS, GyU. 



B. Elytra more oval, pubescence longer, punctua- 



tion coarser and not so close, especially at 



base C. PUNCTIPENNIS, Bris. 



2. Thorax reddish, elytra black with apex and 



shoulders obscurely lighter, or whole upper 



surface black C. RrmcORNis, Steph. 



C. ly coper di, Herbst. One of the largest British species ; oblong, 

 convex, of a rather dark ferruginous colour, with coarse pubescence, 

 and with rows of outstanding setae on elytra ; antennae thick with nar- 

 row club ; head and thorax strongly and deeply punctured, the latter 

 transverse, with anterior angles callose and produced behind in a minute 

 sharp tooth, sides with a sharp tooth just before middle, margins wide, 

 disc with four callosities, transverse impression at base deep ; elytra 

 less thickly and strongly punctured than thorax, the punctures becoming 

 feebler towards apex ; legs ferruginous, anterior tibiae produced externally 

 in a distinct tooth. L. 2-3 mm. 



In Lycoperdons, local but generally distributed throughout the Southern and Mid- 

 land counties ; rarer further north, and apparently not found in the northern counties 

 of England or in Scotland ; Ireland, near Waterfbrd. 



This and the two following species are distinguished by their coarse 

 pubescence and the long setae or bristles set in even rows on the elytra. 



C. Schmidtii, Sturm. This species is compared with C. lycoperdi 

 by Erichson, but is much more closely allied to (7. setulosus, from 

 which it may be distinguished by its rather larger size and less broad 

 build, the less transverse subapical joints of the club of the antennae, 

 the lesser development of the callosity of the anterior angles and the 

 lateral tooth, and also .by the more confused punctuation of the elytra ; 

 the elytra are more contracted behind and less parallel-sided than in 

 C. lycoperdi, from which species it is easily distinguished by not having 

 the anterior tibiae produced into a tooth externally ; in the formation of 

 the thorax it resembles C. saginatus, but that species is smaller and much 

 more finely punctured and pubescent. L. 2|-3 mm. 



In stack refuse ; very rare ; Mr. Champion took a single specimen at Wicken Fen 

 in August, 1870, and another specimen a short time afterwards in the same locality ; 

 Mr. E. W. Janson had taken the same species some years before, probably at Whittlesea. 



C. setulosus, Sturm. Oblong-oval, convex, of a lighter colour 

 than C. lycoperdi, and easily distinguished from that species by the 

 anterior tibiae being simple at apex ; antennae rather stout with the 

 joints of the club not contiguous, the penultimate joints being very 

 transverse ; head and thorax deeply and strongly, but thickly, punc- 

 tured ; thorax very transverse with anterior angles callose but not pro- 

 duced in a tooth behind, sides with a small tooth about middle, margins
