174 M. G. A. Boulenger on a new Genus of Geckos. XXIII.-Description of a new Species of Riopalocera. By W. L. DISTANT. Cyrest�s Earli, n. sp. S. Wings above creamy white, with the basal third of both wings slightly and palely infuscated, with two narrow oblique brownish fasciao :-the first commencing on median nervure and at about centre of cell of anterior wing, and ex-tending to about centre of submedian nervure, down which it is continued to near anal angle; the second commencing on anterior wing at base of second median nervule, and extending to near apex of the third median nervule of posterior wings, whence it is strongly sinuated and angulated to submedian ner-vure. Cell of anterior wings with four transverse brownish fascioe, the fourth at end of cell having a central brownish line; a similarly formed fascia closing cell of posterior wings; an irregular brownish patch beyond cell of anterior wings; at about one third from apex a narrow brownish fascia crosses both wings. The apex of anterior wings is broadly infuscated; and a submarginal series of obscure spots (absent at centre of anterior wings) outwardly margined by a narrow brown fascia crosses both wings; a marginal blackish line; the extreme margin brownish, with creamy white fringe; an ochraceous patch at anal angle of posterior wings, on which are two bluish spots marked with black ; caudate appendages bluish. Wings beneathl much paler than above; markings generally similar, but spots darker, with a large black spot at anal angle of posterior wings, and the spots between the subcostal ner-vules of posterior wings and between the second and third median nervules of anterior wings very prominent and black. Exp. wings 58 millim. 1.ub. Malacca. Coll. Godman and Salvin. This species appears to be intermediate between C. sericeus, Butl, and C. paulinus, Feld. It will be figured in my ' Rhopalocera Malayana.' XX1V.-Description of a new Genus of Geckos. By G. A. BOULENGER. MICROSCALABOTES, g. n.
