is slightly larger than the female, and has much the appearance of 

 a Solenohia, especially when slightly worn. 



Expanse, S 18 millims., 9 16-17 millims. 



Near San Francisco, May 19 th, 1871. 



I have several specimens of this species, of which the females are in 

 better condition than the males. One, or perhaps two other unicolo- 

 rous species of Incurvaria were met with in May and June of the 

 following year in Oregon ; but I shall not venture to describe them 

 until I can be more certain that they do not belong to some of the 

 numerous European species. 



Genus Micropteryx, Hiibner. 



Two species only of this genus have, as far as I am aware, been 

 described from North America ; and of these one only is mentioned 

 in Chambers's " Index to described Tlneina," in the ' Bulletin of the 

 United-States Geological and Geographical Survey,' 1878. This is 

 Micropteryx pomivorella. Pack. (Rep. Mass. Ag. Soc. 1870, Am. 

 Nat. vi. p. 68.1 ). The other is Micropteryx luteiceps. Walk. (Cat. 

 Lep. Het. xxviii. p. 494), from Nova Scotia, a good and distinct 

 species. 



To these may be added the following species from the Western 

 States : — 



Micropteryx pardella, sp. nov. (Plate XI. fig. 11.) 



Capiie hirsuto ochreo ; antennis fuscis ; alis anticis subpurpurascenti' 

 cupreis, liturn dorsali apud basin et maculis duabus post medium 

 aliquando confusis, cum ciliis apicalibus ceneo-Jiavidis, posticis 

 cupreis. 



Head bright ochreous, roughly clothed. Antennae dusky, rather 

 coarse in the male. Fore wings purplish cupreous, with two con- 

 spicuous brassy -yellow spots beyond the middle ; the upper of 

 these, which is the largest, is obliquely quadrangular, reaching the 

 costa along its upper edge, and sometimes blended with the lower 

 and smaller one, which is slightly beyond it and contiguous to the 

 dorsal margin at the anal angle. Before the middle, touching the 

 dorsal margin, and reaching more than half across the wing, is an 

 irregular-shaped spot of a similar colour, blending by means of a 

 yellowish intermediate shade with a small similar spot at the base of 

 the wing. The cilia at the apex and apical margin are brassy yellow, 

 at the anal angle cupreous. Hind wings cupreous. Abdomen dusky. 



J. Expanse 10 millims. 



Five specimens, taken on the borders of the forest of "redwood" 

 {Taxodium sempervirens) near the coast, in Southern Oregon, at the 

 beginning of June 1872. 



Micropteryx aurosparsella, sp. nov. (Plate XI. fig. 12.) 



Capite subgriseo ; antennis brevibus, cinereo-fuscis ; alis anticis 

 purpureis, squamis aureo-metallicis creberrime conspersis, posticis 

 pmpureis. 



Head rough, greyish. Antennae short, less than half the length
