This species was described from specimens taken in Mendocino, 

 Shasta and Colusa counties, Cal. The types are in the British IMuseum, 

 and three paratypes in the Fernald collection. Our attention was first 

 drawn to the distinctness of the species from lobidactylus, of which 

 it had long been recorded as a synonym, by the discovery that all of 

 our Calif ornian specimens had striped antennae, in marked contrast 

 to the dotted antennae of the latter species. Lord Walsingham both 

 described and figured the species with dotted antennae, but in sending 

 material to Mr. Meyrick for comparison with the type we called his 

 attention to this feature, and he noted that they are striped in the types. 

 This is true also of the paratypes in the Fernald collection. In the 

 Grinnell collection of Pterophoridae as sent to us for examination 

 there were no types of Trkhoptilus zvrightii, but in Mr. W. S. Wright's 

 material we found two specimens from the type locality which were 

 true californicHS. Since we have seen only this species from the entire 

 state of California, we feel that Mr. Grinnell was probably guilty of 

 an oversight in describing his species with "barred" antennae.

Since we have seen only two specimens of pygmaeus, one a para- 

 type, we reproduce the original description : 



"Very small and slender. 



"The head pale fawn-colour, with some erect scales above and behind the 

 eyes ; antennae slightly pubescent spotted alternately with fawn-brown and white 

 above; the palpi projecting nearly the length of the head beyond it, whitish, 

 touched with pale fawn-colour. 



"Fore wings cleft slightly more than half tlieir length, very pale fawn- 

 colour, dusted with fuscous-brown scales along the costa, especially above the 

 base of the fissure, also towards the base of the dorsal margin. The two slender 

 lobes diverge considerably, and are barred before and beyond their middles 

 more or less distinctly with white, which extends tlirough the otherwise pale 

 fawn-coloured cilia on both sides; along the base of these intermediate fawn-
