PYRALID.E. EUDIOPTIS. 43 



pupa is brown, with dark spots : the imago appears about the middle of 



June. 



Very abundant in gardens throughout the vicinity of London ; 

 also found in Devonshire, the New Forest, Norfolk, Kent, &c.

Genus CCLXVIII. — Eudioptis, Huhner. 



Palpi four ; maxillary minute, ascending ; labial densely clothed with elon- 

 gated compact scales, forming a large uniform compressed ovate mask, in 

 which the maxillae, which are very long, are concealed ; when denuded, 

 slender, ascending, closely applied to the face, triarticulate, the terminal 

 joint minute. AntenncE long and slender, simple in both sexes : head broad : 

 eyesXavge, subglobose: thorax ample: it'/«^5 entire, subhyaline ; anterior very 

 acute, obliquely truncate behind ; posterior triangular : abdomen elongate, 

 rather short in the males, with a tuft at the apex: legs long and slender; 

 posterior tibiae with two pair of spurs at the apex. 



This very singular genus may be instantly recognized by the great 

 transparency of its pearly, acute, obliquely truncate wings, which 

 have the entire limb of a dark hue : the singular structure of its palpi 

 forms a conspicuous distinguishing character ; it being totally dissi- 

 milar to that of any of the allied genera, and not much unlike that of 

 the genus Prosoponia, amongst the Trichoptera: these organs, 

 although in themselves when denuded slender, forming a large ovate 

 projecting and compressed kind of mask, within which the elongate 

 maxillae lie concealed.

Py. lucernalis. Hubner. — Diaphania lucernalis. Steph. Catal. ii. 16-t. 

 No. 6804. 



Wings pellucid, pearly- white, anterior with the costa and hinder margin 

 broadly dusky, or black ; posterior also with the hinder margui the same, 

 the band gradually diminishing to the anal angle, which is immaculate : 

 cilia, except those of the anal angle of the posterior wings, which are white, 

 also fuscous, or black': head, thorax, and abdomhial tuft the same; rest of 

 the al)domen pure pearly-white. 



In the late Mr. Haworth's collection is a single specimen of this 

 remarkable species, which was taken near London by Mr. Knight ; 

 and I possess a pair captured in Devonshire^ near Plymouth.
