THE GROUP OF CfiOCEUS. 143 



" Taken in the neighbourhood of London, in June, 

 at Darenth Wood, <&c." Stephens, I.e. 



Mr. Kir by (List of Hymen., i, 108) refers the speci- 

 men standing in Stephens' collection as analis to ver- 

 nalis, Htg., S. E. Z., i, 23, 22 (which is, I believe, only 

 caprece, Pz.). He quotes fruticum, Evers., as a syno- 

 nym, stating at the same time that the representative 

 of analis agrees badly with the description. I there- 

 fore give Eversmann's description : " Antennae, head, 

 thorax, and first abdominal segment black ; the rest 

 of the abdomen and mouth and legs rufo-luteous, 

 coxae and base of femora black ; wings hyaline ; 

 stigma and costa brownish-yellow. The ? has the 

 eyes surrounded with yellow. Antenna of the length 

 of the body. Length 2 3 lines." 



XVI. THE GROUP OF CKOCEUS. 



Reddish-luteous entirely, or more generally with two 

 or three black longitudinal marks on mesonotum and a 

 row of transverse marks on abdomen. Antennae usually 

 long and filiform, with the third joint shorter than, or 

 equal in length to, the fourth; in colour luteous entirely, 

 or lined more or less with black above. Clypeus incised. 

 Stigma testaceous. 



This group agrees best in body-form and in the 

 light coloration of the body with the preceding, but 

 the reddish-yellow ground colour separates it. From 

 the other reddish-yellow or yellow species the fact of 

 the thorax being never entirely black above and never 

 so beneath enables them to be easily recognised, 

 except from the Luteus section, from which again the 

 species differ in the short ovipositor. The species are 

 difficult to separate ; in fact, the females can only be 

 clearly distinguished by breeding them from the larvae. 

 These are variously coloured and ornamented.
