Genus LEPTONEURA. 



Leptoneura, Wallengren, Kon,L,d. Sv. Vet.-Akad. Ilandl., 1857; Lep. llhop. 

 Cafir., p. 31 ; Trinicn, Rhop. Ai'r. Aust., ii. 192 (1866). 



Imago. — Closely allied to Fseudonym'pUa. Eyes hairy ; 2'>ttlpi scaly 

 latei'ally, and with much shorter, less bristly hairs (especially beneath) ; 

 the terminal joint shorter, less acute than in Fs&iidonym'plia ; antennm 

 rather short, with the club distinct and rather gradually thickened 

 (except in L. Cassus and Cassina, where it is rounded, abruptly formed, 

 and somewhat flattened). Thorax rather more robust. Wings with 

 neuration similar to that of Pseudonympha, but with the costal nervure 

 of fore-ivings unswollen, and the discoidal cell of hind-ioings much 

 shorter; in the $, on the under side of fore- wings, a narrow, elon- 

 gate, shining greyish space, on inner margin at base, ordinarily hidden 

 by the costa of hind-wings. Fore-legs of $ extremely small, clothed 

 with elongate scales and a few bristly hairs ; tibia rather shorter than 

 femur, short tarsal portion abruptly reduced terminally into a straight 

 acute spine. Iliddle and kind legs short ; femora smooth, scaly ; tibige 

 set with very fine bristles, and with terminal spurs short; tarsi also 

 finely bristly, with a longer, more spiny pair of bristles at end of each 

 articulation beneath. 



Larva. — Rather thick and short ; head large ; tail very shortly 

 bifid. Skin set generally with very short bristles. 



Pupa. — Cylindrical, very thick (especially about middle) ; head and 

 back of thorax very blunted, scarcely prominent. 



Besides the difference noted in the antennee, Z. Cassus, Linn., and 

 Cassina, Bui., are distinguished from their congeners by the more 

 slender terminal joint of the palpi, and by a generally more robust 

 structure of the body, the abdomen being longer and thicker, and tufted 

 at the extremity. 



The Leptoneurm are larger insects than the species of Pseudo- 

 nympha, the two smallest of them (L. Bowkeri and Cassina) being 

 equal in size to the $ P. vigilans, the largest of its genus. Their 

 habits are quite like those of the latter group ; they frequent open 

 ground, several species preferring hilly tracts. Their flight is rather 

 stronger and (in the males) longer sustained than that of Pseudo-
