248 CA.pril. 



On August 25th, 1875, I caught eleven specimens (three c? and 

 eight ? ) of this species near Seaford, Sussex, in company with 

 Thinophilus versutus and Thrypticus hellus, on a marshy spot. 

 C. GEAMINEUS, Fall. 



This is the commonest species of the genus in England, and may 

 be known by its bright blue or green colour, rather small size, small 

 third joint of the antennae, yellow anterior tibiae and black hind tibiae, 

 pale fringed alulae, and silvery white face, which is very narrow in the 

 male. I believe it is universally distributed. It is rather variable, 

 but I have in vain attempted to split off any species from it, until last 

 autumn, when I came to the conclusion that the specimens from Up- 

 ware, in the fens, rej)resent some other species, probably — 



C. MICEOCEEUS, KOW. 



Distinguished from gramineus by its pale hind tibiae, brown 

 fringed alulae, smaller third antennal joint, and in the female by the 

 anterior femora being yellow for fully the last quarter. Kowarz says 

 the antennae usually have the two basal joints reddish, but I am 

 unable to distinguish this character, which would at once settle all 

 doubt, as microcerus is the only Chri/sotus known which has not entirely 

 black antennae ; perhaps more specimens will show that the antennae 

 are sometimes pale. I brought back one male and five females from 

 Upware last July. 



C. LiEsus, Wied. 



This is a well known species, being the only one with the eyes 

 widely separated on the face in the male ; it is of a dark blue colour, 

 the third joint of the antennae and the palpi large, the face broad, 

 grey, and the legs in the male entirely black, which last two characters 

 alone distinguish it from all the rest ; the front coxae are white haired, 

 and the alulae brownish haired; the tibia' of the female are more or 

 less pale. I have caught it sometimes in abundance near Lyndhurst, 

 Eeigate, Woking, &c. 



C. AMPLICOEXIS, Zett. 



This is also a black-legged species, resembling Icesus, but the eyes 

 are approximate in the male, the front coxae are black haired at the 

 tip, the front tibiae bear distinct bristles, and the tibiae of the female 

 are quite black, only just the knees being brownish-yellow. I have 

 caught this in various parts of the New Forest.
