386 PIIYTOPHAOA. [C}l(f-(oCl/<'!H<1. 



C. subcoerulea, Kuts. (SaJilbergii, pars. auct.). Rather elongate, 

 moderately convex, of a unicolorous deep dark blue colour or nigro- 

 cceruleous ; head broad, very closely and finely punctured, antennae 

 dark with the basal joints red, at all events on their under-side ; 

 thorax not strongly transverse, broadest in middle, finely and very 

 closely, but distinctly punctured ; wings present ; elytra at base 

 scarcely broader than thorax, rather strongly punctured in rows, which 

 are irregular near suture towards base, but become regular at apex ; legs 

 ferruginous, more or less infuscate, variable in colour, all the femora 

 dark. L. 2-2} mm. 



Mnrsliy places, by sweeping herbage ; nlso in moss and nt the roots of grass ; very 

 local, but sometimes common where it occurs, although not always ; Wimbledon, 

 Weybridge, Ripley, Esher, Cliobham, Balcombe, Co w fold ; Windsor; IVgwell Bay; 

 Dover; Hastings; St. Leonards . Forest ; Portsmouth district; New Forest; Sun- 

 down, Isle of Wight; it does not occur north of the London district. 



This species has been much confused with C. Sahlbergi, which may 

 bo easily distinguished by its evidently more strongly punctured fore- 

 head; tlxe general punctuation also is stronger, but this is not so 

 apparent. 



C. aridula, Gyll. Oblong-ovate, rather convex, jeneous or nigro- 

 aeneous, moderately shining ; head very finely punctured, antennae black 

 with the base red, the. first joint dark on its upper surface, and the 

 second, and sometimes the following, dark at apex ; thorax about half 

 as broad again as long, according to Allard much longer than in 

 C. aridella, compressed in front, finely and thickly punctured ; wings 

 absent ; elytra broader at base than thorax, punctured much as in the 

 preceding species ; femora dark, tibiaj and tarsi variable, ferruginous, 

 more or less iufuscate. L. 2}-2 mm. 



Damp places, by sweeping herbage ; very rare ; Woking (Champion); Loughton, 

 Essex (Champion); Portsmouth district (Moncreuff); Streusall, York (Hey). 



According to Aliard, this species closely resembles C. aridella (hor- 

 tensis), from which it is distinguished by its very finely punctured head 

 and thorax, the longer thorax, and the fact that the base of the antenna) 

 are spotted with black ; the latter point has given rise to many mistakes, 

 as all the species except P. aridella have the base of the antenna,' in 

 mature examples coloured in much the same fashion. 



C. conftiaa, Boh. Allied to the preceding, but broader, and, as a 

 rule, of a darker colour ; the punctuation also is stronger, and that of 

 the elytra more confused towards base ; the punctuation of the forehead, 

 at all events in the centre, is more diffuse and finer than in either of 

 the preceding species ; the upper surface is very shining ; the thorax is 

 broadest a little behind middle, and is finely and thickly punctured ; 

 the wings are rudimentary; the elytra are almost confusedly punctured 

 on disc, the rows in front being scarcely traceable ; the femora are dark,
