200 DESCRIPIIONS OP ArSTRALTAX MTCEO-LEPIDOPTERA, 



rather inwardly oblique ; third dorsal on anal angle, ratlierbeyond 

 third costal, erect ; fourth costal spot somewhat inwardly oblique, 

 close before apex, adjoining a round black apical spot : cilia dark 

 grey, basal third within a black line blackish round apex. Hind- 

 wings dark fuscous-grey, cilia dark grey. 



A magnificent species, though some specimens are amongst ' 

 the very smallest of the Leindoptera ; it is undoubtedly allied to tlie 

 North American Z. desmocUella, Clem., differing, so far as can bo 

 j udged from the description, principally in the orange ground- 

 colour, deep black base, and somewhat differently arranged 

 markings. 



Larva gradually attenuated from second segment throughout, 

 head triangular, much smaller than second segment ; glossy 

 whitish, dorsal vessel dark green ; head faintly amber-tinged. 

 Mines a small blotch beneath lower surface of leaves of Desmoiiuin 

 sp. — [Legtuninosai), the epidermis contracting to produce a 

 dilated chamber. Pupa free within the mine. I found the larva 

 early in March in the Botanical Gardens, Sydney, and bred the 

 imago in abundance towards the end of the same month, and 

 also took them sitting on the leaves of the food-plant. 



I hope to obtain further information on the origin of this 

 species. There are only two specimens of the food-plant in the 

 gardens, without name or indication of country, and I have not 

 seen it elsewhere; I believe it to be a true Desmodium. The 

 insect is certainly of an American type, but I have found no 

 other instance of a leaf -feeding Micro being imported from such 

 a distance, though it would not seem impossible ; I am not aware 

 of any described American species with which it is identifiable. 

 I'ossiblj^ it may come from the islands.
