14 HAUSTELI.ATA. — LEPIDOPTF.RA. 



bundle of hairs, capable of being expanded, and at the apex a series of 

 shorter ones, and the anterior tarsi wanting ? 



In general habit this genus differs considerably from the two fol- 

 lowing, notwithstanding the males are distinguished by having an ex- 

 pansive fascicle of elongate hairs on the anterior legs, the structure of 

 the palpi is slightly dissimilar, and the wings are abbreviated, of 

 almost uniform colour, and destitute of transverse streaks : my speci- 

 men of the male has no rudiments of anterior tarsi. 



Sp. 1. cribralis. Alis albidis, anticis puncto medio nigra serieque dvplici punc- 

 torumfuscorum. (Exp. Alar. 1 unc. — 1 unc. 2 lin.) 



Py. cribralis. Hiibner. — Polypogon cribralis. Steph. Catal. ii. 158. No. 6761. 



Wings dusky-whitish ; anterior with a small central black dot, and an obscure 

 double row of dusky ones towards the hinder margin; on the latter is a 

 faint dusky Une : cilia whitish : posterior wings ashy-white, with the cilia 

 darker. 



The only locality I am aware of for this species is in the vicinity 

 of Whittlesea Mere, in the fenny district surrounding which it does 

 not appear to be very uncommon towards the end of June or be- 

 ginning of July, having taken it on the 4th of that month last year. 



Genus CCXLVIII. — Peciiipogon,* Hillmer. 



Palpi porrected, very long, densely clothed to the apex with elongate scales, 

 triarticulate, the terminal jonit recurved, basal small, second thrice as long 

 as the apical, attenuated at the base and apex, terminal one slender aciculate : 

 maxillae rather long. Antenna, in the males, bipectinated nearly to the apex, 

 in the females simply ciliated beneath : head with a conical tuft of hairs 

 between the antenna;: f/iornx slender : wings entire, anterior rather elongate- 

 triangular, with irregular dark streaks; posterior rounded, also transversely 

 streaked : abdomen rather long, slightly tufted in the males, acute in the 

 females : legs slender, simple in the females, with two pair of spurs on the 

 posterior tibiae ; in the males the anterior tibiae have a fascicle of hairs at the 

 base, capable of expanding like a fan ; tarsi slender. Larva with fourteen 

 legs, slender : pupa also slender, folliculated. 



From the following genus Pechipogon differs by having the palpi 



* The name Polypogon employed in my Catalogue for this and the following 

 genera must be changed for two reasons ; first, that it has long been pre- 

 occupied in botany, and secondly from Hiibner having otherwise named and 

 characterized these genera.
