TOUTRICID.K, EAIUS. GJ 



Not uncommon in woody places within the metropolitan district, 

 especially in Coombc, Darentli, and Birch woods; also found in 

 Devonshire. " Gihside, Sec." — G. IVailes, Esq.

Head above, thorax and anterior wings deep grass green, the latter with the 

 costa, inner edge, two slender oblique streaks, and the cilia white, sometimes 

 with a yellowish tinge : posterior pure glossy white : antenna, palpi and 

 legs red. 



The streaks on the anterior wings are occasionally a little waved. 



Caterpillar green, with a lateral yellowish line, the second segment with a 

 dorsal tubercle : it feeds on the oak, alder, &c.: the pupa is pale green, 

 with a black dorsal line: the imago appears about the middle of June. 



Much rarer than the foregoing species ; found throughout the 

 metropolitan district in similar situations with the preceding. "Once 

 at Tanfield by Mr. Thornhill."— G. Wailes, Esq. 



Genus CCLXXV.— Eaius, Hiibner. 



Palpi short, ascending, parallel, densely clothed with short compact scales, 

 terminal joint somewhat horizontally porrccted ; basal joint short, second 

 rather stouter and elongate, third short, ovate-acute : vKuilla a littl 

 elongate. Antenna; simple in both sexes, faintly pubescent beneath in the 

 males : head rather broad, with depressed scales between the antennte : eyes 

 large, globose: thorax rather short, not crested: unngs short, anterior 

 broad triangular, straight at the base, plain with pale margins ; posterior 

 ample, ovate-triangular, somewhat diaphanous : body slender, obtuse, with, 

 a small tuft at the apex : legs short. Caterpillar free, convex, attenuated 

 at both ends, with sixteen legs ; head small : pupa subconic, enclosed in a 

 firm cocoon, with a conical apex. 



In my Catalogue I associated the present genus with the following, 

 and it has also been attached to the foregoing, but it evidently belongs 

 to neither : in the habit of the larva and pupa it is allied to the last, 

 the larva being exposed, that is, not resident in a twisted leaf, and 

 the pupa is placed in a firm cocoon, but the imago is manifestly 

 more allied to Tortrix, from which it chiefly differs in the structure of 

 the palpi and in having the wings entirely of uniform colours, with 



pale margins.
