cilia all short : body long and slender, with a small tuft at the apex, stouter 

 in the females. 



Yp. Evonymella is given as the type of this genus by Latreille in 

 the 3rd volume of his Histoire Naturellc des Crustaces et des Insects, 

 I have therefore here, as in my Catalogue, adhered to his nomen- 

 clature. From the remarks appended to Anesychia it will be evident 

 that this genus ought to be divided from Yponomeuta: the palpi 

 are slender, porrected nearly horizontally, the anterior wings are 

 somewhat rounded on the hinder margin, and adorned throughout 

 with minute distinct black dots, disposed with some regularity in lon- 

 gitudinal hues on a pale lead-coloured or whitish ground : the larva? 

 reside in large communities, and commit great devastations from 

 their numbers. This genus is synonymous with Nygmia of Hubner. 



Sp. 1. Evonymella. Alis anticis niveis pvuctis minutii circiter quinquaginta 

 nig)-is, posticisfuscis. (Exp. Alar. 8 — 12 lin.) 



Ph. Ti. Evonymella. Linne. — Donovan, xi. pi. 355, f. 4. — Yp. Evonymella. 

 Steph. Catal. ii. 203. Xo. 7270. 



Anterior wings snow-white, each with about four longitudinal rows of minute 

 black dots, placed somewhat regularly towards the base, and on the inner 

 margin, but confusedly towards the apex, in number about fifty : cilia 

 immaculate: posterior wings and abdomen above fuscous; cilia ashy: head 

 immaculate-white : thorax white, with four black dots. 



Caterpillar ochreous-yellow, with ten black dots on each side, and a brown 

 head; it feeds gregariously in a large net on the Spindle- tree (^MOwT/mwi 

 Europceus): the imago appears towards the end of June, and continues to 

 ths beginning of August. 



Not common ; but found at times rather plentifully in hedges and 

 gardens at the top of i\Iaidcn-lane, near Highgate : also taken near 

 Darenth wood and Hertford, and in the New Forest and Devon- 

 shire. 



Sp. 2. irrorella. Alis anticii sordide albidis punctis numerosis atris, maculaque 

 suhposticafuliginosa. (Exp. Alar. 11 lin. — 1 unc.) 



Ti. irrorella. //"Miner ?—Yp. irrorella. Sfeph. Catal. iu 203. No. 7271. 



Anterior wings dull whitish, or cream-colour, with a large smoky blotch 

 towards the hinder margin, the disc with numerous minute black dots, irre- 

 gularly disposed ; cilia lead-colour: posterior wings and abdomen lead- 

 coloured-brown, cilia the same: head and thorax white, the latter with 

 four black dots. 



Very rare: I have a pair which I found many years since at
