Nine Exotic Species of the Genus Gracilaria. 297 



Gracilaria Gemoniella, n. sp. (PI. X. fig. 6.) 

 Alis anticis costam versus fuscis, dorsum versus albis, strigiila 



alba costae pone medium, strigula fusca dorsi ad angulum 



analem, macula magna apicis alba. 

 Exp. al. 3 lin. 



Head white, with a few fuscous scales. Face white. Maxillary 

 palpi white. Labial palpi white, the tip of the second joint dark 

 grey. Antennae fuscous, annulated with white. 



Anterior wings pale brown along the costa, white along the inner 

 margin; the division of colour runs nearly along the fold, only in 

 the middle and just beyond are two rounded white projections on 

 the costal side of the fold; beyond these is a short white oblique 

 streak from the costa, and below it a slender pale brown streak runs 

 to the anal angle — beyond which a white blotch occupies nearly 

 the whole of the tip of the wing, the costa being only narrowly 

 brown — at the apex is a short curved black streak. Cilia white, 

 with the tips grey, intersected by a short black streak, opposite the 

 apex of the wing ; cilia of the inner margin pale greyish-brown. 



Posterior wings dark grey, with paler cilia. 



Abdomen brownish above, whitish beneath. 



Anterior legs : femora and tibiae white ; tarsi white, with dark 

 grey spots. Middle legs : femora whitish ; tibiae white, with a dark 

 grey patch at the tip ; tarsi white, spotted with pale grey. Hind 

 legs : femora whitish ; tibiae pale fuscous ; tarsi dark grey, with 

 white spots. 



I have only seen one specimen, of which the antennae are partly 

 broken, and the thorax invisible on account of the pin. It is a 

 true Gracilaria, and is closely allied to Scalariella, being similar 

 in colour and markings, though so much smaller. The large sub- 

 apical spot in Gemoniella is the most striking distinctive cha- 

 racter, as in Scalariella that portion of the wing is nearly all 

 brown. In Scalariella the anterior tibiae are almost black. 



This insect was bred by Mr. Atkinson from a larva found near 

 Calcutta, at the end of July, mining the upper surface of a leaf of 

 some plant (name unknown). 



Gracilaria Calicella, n. sp. (PI. X. fig. 7.) 

 Alis anticis luteo-brunneis, fasciis duabus, maculis duabus costas 

 parvis, macula majore dorsi, strigulaque obliqua apicis albis. 

 Exp. al. 3 lin. 



Head and face white. Maxillary and labial palpi white. An- 

 tennae grey, with hardly perceptibly paler annulations.
