entire length of till) veins, ill the former not iiiDiv th;iu oiio-fourlh ; this is an iu- 

 toresting instance of geographical variation of structure, but probably from inter- 

 mediate localities connecting forms would be obtained. Algerian specimens are also 

 somewhat smaller, ami have the hind-wingi darker grey, but do not differ in this 

 respect from South European forms. .E. disertella, H.-S. — Philippevillc ; three 

 specimens. 



E. ECHIDNIAS, n. sp. 



? . 9 ram. Head light grey, face whitish. Palpi white, second joint exter- 

 nally dark fuscous except apex, terminal joint with base and three rings dark fuscous. 

 Antennae dark grey, basal joint dark in front. Thorax grey, apical Iialf of patagia, 

 ochreous-whitish. Abdomen ochreous-grey-whitish, apical segment beneath and on 

 sides with a plate of black hair-scales, partially concealed beneath pearly, flat .scales, 

 but probalily expansible. Li^gs dark grey, apes of joints and hairs of posterior tibisa 

 whitish. Fore-wings lanceolate ; dark grey, sprinkled with whitish ; an irregular 

 whitish streak from base beneath costa to one-third, thence curved down, passing 

 through middle of disc and curved back to costa at two-thirds ; two cloudy blackish 

 dots benea*^h this streak at one-third and two-thirds of disc, each followed by an 

 obscure, wliitish, transverse mark connecting streak with inner margin ; a very 

 acutely angulated, fine, black, transverse line near before apex : cilia whitisli-grey, 

 base mixed with dark grey scales round apex. Hind-wings grey : cilia whitisli-grey. 



Biskra ; one specimen. This is a singularly distinct species, yet 

 in a manner intermediate between the pale species and the nigrella 

 group. 



Urodeta cisticolella, Stt. — one specimen at Philippevillc. 



Tischeria marginea, Hw. — Philippeville ; commonly beaten from bramble. The 

 circumstances of capture leave no doubt that these specimens belong to a bramble- 

 feeding species, and I consider them certainly a geographical form of marginea ; but 

 the fore-wings are more or less wholly suif used with ferruginous, and the insect 

 appears much darker, the black dot at tlie anal angle being obliteratisd. Specimens 

 from the South of France in Mr. Stainton's collection made no approach to this 

 colouring. 



Bucculatrix cratcegi, 7i. — Philippeville ; three specimens. 



Cemiostoma susinella, H.-S. — two specimens beaten from aspen at Philippeville. 



Coriscium Brongniardellum, F. — Constantino ; one specimen. I consider the 

 identification safe, but the specimen differs from any English types that I have seen, 

 being a dark obscure form, witli the wliite markings nearly obsolete. 



LiTHOCOLLETIS IDOLIA3, «. SJ}. 



(J. 8 mm. Head and thorax briglit saffron, face and pali)i silvery-white. An- 

 tennae whitish-saffron, beneath white. Abdomen grey, anal tuft whitish-ochreous. 

 Legs whitish, median band and apex of anterior and middle tibiae, and apex of some 

 tarsal joints, black. Fore-wings lanceolate ; light golden-orange ; costa whitish- 

 tinged on anterior half ; three fine outwardly oblique black lines from costa before, 

 in, and beyond middle, reaching half across wing, obtusely bent downwards in mid- 

 dle, but lower portion sometimes obsolete, space between first two whitish towards 

 costa, third obscurely margined posteriorly with whitish ; two faintly paler, oblique.
