1897. J WEST-INDIAN MICRO-LEPIDOPTERA. 151 



Hind wings very narrow, elongate, attenuate : cilia 5. Neuration: 

 7 veins; 3 and 4 coincident, cell open, 5 and 6 stalked. 



Legs : hind tibiae pectinate above throughout, inner spurs much 

 longer than the outer. 



The pectinate hind tibiae separate this genus from Gracilaria 

 and Ornix, to which it is allied.

Antennae smoky-whitish. Palpi white, unspotted. Head and

 Fore wings pale copper-brown, with two large shining white 

 triangular patches on the dorsum, their apices reaching the costa ; 

 the first, at the base, covering nearly one-third of the dorsum, the 

 second on the middle, both delicately margined with black scales 

 externally, the second also internally ; beyond these at the tornus 

 is an elongate subovate shining silvery-white dorsal patch, above 

 which a short oblique slender white costal streaklet, black-margined 

 on either side, crosses to the termen before the apex ; cilia at the 

 apex greyish, with two short dividing streaklets, below the apex 

 coppery brown, at the tornus shining white and behind it greyish.

Hab. West Indies — St. Croix, 17 V. (Gudmann); St. Thomas, 

 2 IV. (Hedemann) ; St. Jan, 4 IV. (Gudmann). Three specimens. 



This species belongs to the group of scalariella, Z., and is most 

 nearly allied to nolckenii^.Z. Bred by Mr. Gudmann, but the 

 plant not identified. 



234. DlALECTICA RENDALLI, Sp. 11. 



Antenna; brownish. Palpi white. Head and thorax white,. 

 the latter shaded across the front with brown. Fore wings brown 

 with two broad snow-white transverse fascia; followed by a slender 

 oblique costal streak and a semicircular subapical costal spot, with 

 some white scales around the apex and about the tornus ; the 

 first fascia is broader on the dorsal than on its costal extremity, 

 the second is slightly oblique, tending outwards from the costa, 

 and is somewhat widened towards the dorsum; cilia brownish 

 grey. Exp. al. 7 mm. Hind wings and cilia dark brownish grey. 

 Abdomen greyish brown. Legs \ hind tibiae with a comb of bristly 

 scales above ; white, shaded along the tibiae and banded on the 

 tarsi with brown.
