IleineuKinii oinitled to give the Food-plant of hilineeJla, but Rajronot 

 made a M8. note in liis co])y of Standi ii<^(;r and VVocke's Cataloii that 

 it led on Ildiantlicmnm vuhjnre. Th(;re are at least two species of 

 Hclianthemum at, or near, ]3iskra on which I have had occasion to 

 search very persistently for other larvae, and had there been a 

 Colcophora case upon thcui I could not have failed to observe it. 



3721 : 1. — COLKOPHORA IIU'I'ODUOMIUA, Sp. U. 



Antennae wliito, with distinct black ainiulations ; a short hoary grey tuft on 

 the basal joint. I'aljyi short, ilcpciulent ; Iioary whitish. Head greyish white. 

 Tliorax olivaceous fawn, with a narrow wliito streak along the outer edge of the 

 tcgulac. Furcwing.i olivaceous ochreous, fading to greyish ochreous along the dor- 

 sum, with a line of a few iinlistinct fuscous scales above the outer end of the fold ; 

 the cosla from the b:isc is narrowly pure white to about two-lifthi, where the white 

 band is rather abruptly dilalod to 1 wici; its width and so continued to above the 

 n\)c\ ; the cilia at the apex are fawn-grey, a short slender white streak running 

 through them immediately below the apex, dorsal cilia pale brownish grey. Exp. 

 al. H — 12 mm. Ilindwings shining, pale stcel-grcy ; cilia pale brownish grey. 

 Abdomen dusky cinereous. Legs whitish.

The somewhat abrupt dilatation outwardly of the white costal 

 band renders this species distinct ; it is nearest to frieiitclln, Chr. 

 (3721), which however is easily separable by the dense clothing of 

 the ;intennao toward the base, and by the more uniform tint of the 

 darker portion of the wing-surface, which in hippodromica is distinctly 

 paler dorsally. The type was taken on a very wiiidy day on the hills 

 overlooking the Hippodrome, or new race-course, at Biskra, but the 

 bred specimen is from Hammam-es-Salahim. I bred this species 

 from a very obscure-looking case on Astragalus gomho, apparently 

 formed from the end of a young leaf. It was accidently taken 

 among leaves gathered to feed other larvae and observed only when 

 crawling u[) the bottle. Further search among the same plants 

 (vvhiidi grow on the plains but not on the hillsides) was quite 

 fruitless, and even when the moth was bred I had the utmost dilliculty 

 in recovering the case from among the leaves to which it had become 

 attached.
