ii. p]lytra witliout pores on the 5th iaterstice, and only 

 two or three on 3rd. 



1. Posterior tarsi witli first joint rather flattened on its 



interior border ; insect winded C. FCSCrS, F. 



2. Posterior tarsi with first joint convex on its interior 



border : insect apterous. 



A. Posterior angles of thorax right angles, colour 



black C. FLAVIPES, Fourc. 



B. Posterior angles of thorax very blunt or rounded. 



a. Head yellow or pitchy brown ; episterna of 



metathorax prolonged behind C. MOLLIS, Marsh. 



b. Head black ; episterna of metathorax rather 



short, 

 a*. Thorax red or red with dark disc ; border of 



posterior angles very narrow, not raised . . C.MELANOCKPHAT.rs.Z. 



V. nubigena, Hal. 

 b*. Thorax except extreme margins dark ; border 



of ])Osterior angles broad, raised C. MICBOPTEETJS, Duft. 



II. Tarsi simple in both sexes [Amphijynas, Haliday) . . C. piceUS, Marsh. 



C. cisteloides, Vanz.{ftiscij7es,Gcezc,Jlavipee, Payk.). Black, apterous, 

 aiitomai aiul ]ialpi pitchy, more or less red, basal joint entirel)^ red ; 

 thorax suhquadrate, as long as broad, slightly narrower in front, posterior 

 angles blunt right angles, dorsal furrow usually abbreviated in front 

 and behind, but sometimes distinct throughout, base coarsely punctured 

 Avith two fovete on each side, the outer one more or less obsolete ; elytra 

 at base broader than base of thorax, rather deeply striated ; the fifth 

 stria and the third interstice arc each furnished with a row of pores, 

 the latter row as well as the former being often situated in the stria 

 itself ; legs entirely red, or red with pitchy femora, or entirely black. 

 L. 9-12 mm. 



In moss, under stones, &c. ; very common and widely distributed throughout the 

 kingdom. 



C. fuscus, F. {amhiguuit, Payk.). Broad, entirely fuscous brown, 

 witli the margins of thorax, palpi, antennte and legs testaceous ; thorax 

 subrpiadrate, somewhat narrowed in front, posterior angles slightly 

 acute, dorsal furrow distinct, base with a very broad smooth shallow 

 depression on each side ; elytra almost oval, finely striated, the striaj 

 iinpunctate, third interstice with two pores : smaller specimens are very 

 likely to be confounded with C. mull its, anil darker ones with C. Jhtripoi, 

 l)ut they ma}' be easily distinguished by the distinct ilattening or 

 hdlldwing of the inner side of the first joint of the tarsi, which is not 

 })erceptible in those species ; the wings in the European s^jecimens are 

 well developed, but AVollaston (Ins. ^lad., p. 31) records a race from 

 ]\radeira which is entirely apterous, or has only rudimentary wings. 

 L. 9-10 mm. 



Sandy ]ilaces, beneath dry dung, moss, k,c. ; local, but widely distributed along 

 the soniliern coasts tif Kni^land anil Wales; it is rarer in the north, and I can find 

 no record from Ireland. Scotland, local, Forth, Moray.
