Type J . ]Mus. \Vl>ni. 



Hab. E(}vrPT. Larva in cotton-pods. 



When the forewiugs are denuded transverse striie are 

 observable, between the veins, giving a reticulated appearance. 

 These are due to lines of thickening from which the majority 

 of the liighly-developed scales arise; they are almost per- 

 pendicular and extend from costa to dorsum. This structure 

 occurs also in Opuyona uurisqiianiosa, Btl., and in Siar/mato- 

 phora [Pyroderces) argyroyrammos, Z. ; if not overlooked it 

 is apparently unrecorded. 



The specimens are broken and in poor condition. The 

 habits of" the species itre particularly interesting, as being 

 apparently similar to those of Batruchedra Rileyi, Wlsm., 

 discovered in Georgia among rotten cotton-bolls. The 

 similarity in colour and markings between the two insects 

 is so close as to suggest the idea of mimicry (which, in 

 this case, can of course be only synehromatism) ; but the 

 form of the palpi and the breadth of the hind wings, apart 

 from tlic question of neuration, are at once sufficient to 

 distinguish them and to place them iu different genera. 



Note. — In February last Mr. Walter Draper, of the 

 Government Gardens, Delta Barrage, Egypt, sent to the 

 British Museum some cotton-pods infested with a Hemipterous 

 insect {Oxycarenus liyalinipennis, Costa) and numerous 

 small caterpillars. Lately on looking at the bottle I found 

 a number of small moths, all dead, and mostly with all 

 their scales rubbed off'. As Mr. Di-aper, who discovered this 

 new pest in the cotton, wished to h:ive its name, I sent 

 specimens to Loi'd Walsingham for determination, and these 

 are the subjects of the foregoing description. — Chas. O.
