11$ [October. 



with in Oregon or California), was first described by Pitch, and two 

 others, O. delaivaricus, and O. nigrociliatus, by Zeller in his " Beitrage 

 zur Kenntniss der INTordamerikanischen IS" achtf alter." The other, O. 

 ningoris, Wlsm., is new, and seems to me more allied to O. didactylus 

 than to any other European species. 



Only one Mimeseoptilus is here mentioned, which is anew species, 

 M. exclamationis, Wlsm. Prof. Zeller, however, in the work before 

 mentioned, records two others from Texas, M. semicostatus and M. 

 pumilio, this last seems an especially interesting little species, being 

 only the size of Lioptilus microdaetylus, and distinguished from all 

 other Mimeseoptili" by the short and broad fore-wings, which are of a 

 fawn-brown colour, marked with three very distinct black spots." The 

 species described by our author is nearly allied to M. coprodactylus. 



The CEdematopliori are a very interesting addition to our known 

 plumes. Pour species are here described, CE. grisescens, Wlsm., CE. 

 gypsodactylus, Pitch, (creti), CE. guttatus, Wlsm., and CE. occidentalis, 

 Wlsm., and to these Professor Zeller adds a fifth, CE. inquinatus, Zell., 

 from Texas. Owing to the kindness of Lord Walsingham* two fine 

 specimens of CE. grisescens are now in my cabinet, and before me at 

 the present time, but they seem to me so very closely allied to the 

 European CE. Rogenhoferi from the Tyrol, that I confess myself unable 

 to separate them, it would seem that gypsodactylus is also very similar 

 to this but paler in hue and smaller ; guttatus and occidentalis are 

 very different, both of much the same type as our native lithodactylus, 

 but the former " whitish -cinereous dusted with small black scales to- 

 wards the costa and on the dorsal surface, and with a conspicuous 

 whitish spot at the base of the fissure ; " the other, occidentalis, a 

 rather larger species, having two varieties, one pale whitish-ochreous 

 and the other paler. This is a very handsome insect, with the 

 markings less distinct than in lithodactylus, yet the following extract 

 from the description shows how close an ally it is to that species : 

 "Pore-wings whitish-ochreous (more yellow than in lithodactylus) , 

 the costa and apex slightly shaded and the dorsal margin delicately 

 tinged with pale fawn-colour, a dark fawn coloured spot before the 

 base of the fissure is more or less connected obliquely with an elongated 

 spot of the same colour on the costa beyond it. The cilia are delicately 

 tinged with very pale fawn-colour." The larva of this species was 

 found on the leaves of a "sun-flower," so that like its English 

 congener it feeds on the Composita3. CE. inquinatus, of Zeller, seems 



* I take this opportunity of thanking Lord Walsiugham for his great kindness in giving me 

 specimens of most of the plume3 here mentioned.
