NEW BRITISH SPECIES IN 1859. 135 



Opostega Spatulella, Guenee. 

 Alls anticis griseis, grosse-squamatis, maculis quatuor oppo- 

 sitis d'dutioribus luteis. 



Exp. al. 4c\ lin. 



Tuft of the head ochreous-brownish ; the eye-caps yellow- 

 ish-ochrebus, with a grey band of variable width. 



Anterior wings coarsely scaled, grey, with faint indications 

 of two pairs of opposite marginal spots of a pale ochreous ; 

 cilia greyish-ochreous. 



Posterior wings pale grey, with greyish-ochreous cilia. 



Mr. H. Tompkins took four specimens of this insect at 

 Southend in Essex, in the middle of August, among mixed 

 herbage ; it had previously only occurred in France near 

 Chateaudun. A peculiarity of this insect is its extreme ten- 

 dency to grease, whereby the pale spots become obliterated, 

 and only the intermediate space appears a little darker ; hence 

 Herrich-S chaffer describes the anterior wings with a darker 

 spot on the middle of the costa and inner margin, as in Cre- 

 pusculella. 



Nepticula Castanella, Edleston. 

 The occurrence of this insect is thus noticed in the Intel- 

 ligencer, vol. v. p. 123. " Mr. Edleston lately sent for 

 determination a number of insects, and amongst them two 

 specimens of a Nepticula taken amongst Spanish chestnuts, 

 and for which Mr. Edleston proposed the name Castanella ; 

 this appears to be a distinct species, something allied to 

 Tityrella, but the fascia straighter and placed nearer the 

 hind margin."
