General characters of Amblypodia. 



Eyes hairy. 



Labial Palpi scaly or hairy : terminal joint in the female rather longer and slenderer than in the males. 



Antenna gradually clavate, the club rather more distinct than in the preceding genus ; joints of moderate length, 

 partly ringed with white. 



Fore Wings witli the postcostal vein emitting three branches ; the third considerably beyond the discoidal cell. 

 Upper disco-cellular vein obsolete. The upper discoidal vein arising from the postcostal beyond tlie discoidal 

 cell ; the lower disco-cellular vein almost obsolete. 



Hind Wings with only one tail, arising at the extremity of the first branch of the median vein. The anal lobe 

 in some species (D. Ataxns) scarcely distinct, in others produced and rounded (D. Isocrates). Upper disco- 

 cellular vein arising at a greater or less distnnce from the origin of the branch of the postcostal vein. 



Fore Legs of the male as long as those of the female, with tlie thighs in D. Ataxus outwardly clothed with long- 

 fine hairs. Tarsus composed of a single joint, truncate at the tip in D. Ataxus, and with a single deflexed 

 spine ; in D. Isocrates more attenuated, and curved at the tip, which is terminated by a horny oblique point. 



Caterpillar of D. Xenophon elongate-ovate, de])resso-scutate, and furnished with transverse rows of small 



fascicles of short hairs. 

 Chrysalis; smooth, short. 



The type of this genus (Th. Syla Kollar, D. Pholus E. D.) is an Indian insect which has a general resemblance to the tyi)es of Am- 

 blypodia, the male being golden green on the upper surface of the wings, with a black margin (thus resembling Amb. Eumolplnis which 

 may possiljly be congenerous), whilst the female (Amb.? Euijhranorii. Z).) has the disc of the fore wings blue, with a white spot 

 beyond the middle, and a broad dark brown margin. From the typical Amlilypodia; they are at once distinguished by the hairy eyes 

 and palpi, and the want of an upper disco-cellular vein in the fore wings. The latter character, together with the hairy cye.s, also 

 separate D. Isocrates, Xenophon, &c., from the Amblypodia (with the double-tailed golden-niarked species of which genus they are 

 united by Mr. E. Doubleday into the genus Aphnicus). Dr. Ilorsficld had, however, properly separated them, most probably influenced 

 by the t^rseiculated character of the lar\K. The natural history of D. Isocrates, the transformations of which are passed w Ithin the 

 hollowed fruit of the pomegranate, has been above referred to. The species are natives of the East.
