YPONOMEUTID.B. COCHLEOFHASlA OFORINIA. 233 



The insects of this genus may be known by the smoothness and 

 simple colouring of the anterior wings, which are destitute of fascia?, 

 and have the surface mottled or tessellated with a light colour upon 

 a darker ground; the cilia are short and satiny; the palpi also short, 

 and the maxillae are obliterated ; the antennae slightly pubescent in 

 the males, simple in the females, which sex is perfectly apterous. 



Sp. 1. tessellea. Alis anitcis subfuscis, pallida obsolete tessellatis, posticis imma- 



culaiis, antennis villosuUs. (Exp. Alar. $, 7 — 8^ lin.)

Co. tessellea. Curtis, v. x. pi. 487. 



Anterior wings pale brownish, obscurely tessellated with a paler tint, especially 

 towards the hinder margin ; the costa towards the apex sometimes with 

 three or four larger, pale spots : posterior wings immaculate : head bright 

 ochreous : antennae slightly downy. Female apterous ; dull chestnut, with 

 a brownish tuft towards the apex of the abdomen. 



In my series I have specimens with several large pale spots towards the apex 

 of the costa. 



Found, but not commonly, in various places iij the vicinity of 

 London : I have taken it at Darenth wood and near Hertford : it has 

 also occurred near Southampton at the end of May. 



Sp. 2. pubicornis. Alis anticis pallide ochraceo-fuscescentibus immaculatis, 



posticis pallidefuscis, antennis pubescentibus. (Exp. Alar. $, 7^ — 8 lin.) 

 Ca. pubicornis. Haworth. — N. G. pubicornis. Steph. Catal. ii. 201. No. 7258. 



Anterior wings very pale ochreous-brown, totally immaculate; costa whitish: 

 posterior pale brownish : head yellow : antennae pubescent, as long as the 

 body. 



In Mr. Haworth's late collection was a single injured specimen of 

 this very remarkable species, which was captured near London ; I 

 possess a very fine specimen that was found in July 1821 near 

 Brockenhurst, in the New Forest. " Cramond." — Rev. W. Little.

Palpi very short, porrect, slightly depending, clothed at the base with rather 

 long compact scales, the terminal joint exposed, short, acute : majcilla; 

 wanting. Antenna: about half the length of the wings, rather stout at the 

 base, joints distinct, clothed with fine pubescence withhi ; simple in the 

 females : head transverse, with the forehead slightly crested : eyes large,
