Genus LEPTONEURA. 
Leptoneura, Wallengren, Kongl. Sv. Vet.-Akad. Handl., 1857 ; Lep. Bliop. 
CafFr., p. 31; Trinien, Rliop. Afr. Aust., ii. 192 (1866). 
Imago. — Closely allied to Pseudonym^jha. Eyes hairy ; imlpi scaly 
laterally, and with much shorter, less bristly hairs (especially beneath) ; 
the terminal joint shorter, less acute than in Pseudomjmpha ; antennw 
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 Fsmdony minim ^ but with the costal nervure 
of fore-wings unswollen, and the discoidal cell of hind-ivings 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. Middle and Jdnd legs short ; femora smooth, scaly ; tibiae 
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. 
Laeva. — 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 antennae, L. Cassus, Linn., and 
Cassinay 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- 
nymj)ha, the two smallest of them (Z. Boiukeri 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-
