189. GENUS LAMBORNIA, NOV. GEN., PROUT 
Lambornia, nov. gen. Prout. 
Characters. Face smooth, broad. Palpus slender, in cf shortish, in Q moderate, second 
joind smooth-scaled, third joint distinct, in cf not minute, in Q elongate. Tongue developed. Antenna 
rather short, in both sexes bipectinate to rather near apex, the branches quite moderate. Pectus some- 
what hairy. Femora glabrous. Hindtibia in both sexes with a pair of unequal terminal spurs, the 
median wanting. Abdomen with minute raised dorsal spots (embryo crests). Forewing short and broad, 
costa arched, apex blunt, termen subcrenulate, curved, becoming oblique, cell short, DC slightly 
incurved, oblique posteriorly, SC! from cell, anastomosing strongly with C, SC? from stalk of SC?5, 
anastomosing strongly with SCl, or even with C 4- SC! before their separation, R! about connate, 
R? from about centre of DC, M! connate; hindwing elongate, apex rounded off, termen dentate, with 
stronger teeth at R! and R?, excised between, tornus rather pronounced, inner margin very long, cell 
very short, DC not much curved, sometimes slightly angled at origin of R?, C closely approximated to 
one-half cell or less, then rapidly diverging, SC? long-stalked, R? from little above middle, sometimes 
almost central, M! long-stalked. 
Early stages unknown. 
A thoroughly distinct genus. Perhaps nearest in facies to Ber/a, but differing in several characters 
(tibial armature, antennal structure, origin of SC!, stumpier forewing). May be derived from an 
immediate ancestor of Berta, prior to the stalking of SC,

Characters. — Face smooth. Palpus slender, in cf moderate to rather long, in Q long, second 
joint smooth-scaled, third joint smooth, distinct, in cf moderate (rarely short), in Q long. Tongue 
present. Antenna moderate, in cj bipectinate to two-thirds with long branches, in Q serrate or simple. 
Pectus almost glabrous. Femora glabrous. Hindtibia in C dilated, with hair-pencil and sometimes a 
short terminal process, in both sexes with all spurs. Abdomen not crested. Forewing with costa slightly 
to moderately arched, apex usually acute, termen oblique, nearly straight or curved, tornus in typical 
1 Lambornia inspiciens, nov. sp. — c Q,. 19-22 mm. Face dull olive-green. Palpus reddish above, whitish beneath. Vertex and base 
of antennal shaft white, the latter distally reddish ochreous. Thorax fuscous olive above, abdomen at base dorsally tinged with reddish fuscous, otherwise 
paler, with minute reddish-fuscous raised spots. Wings white, smoothly scaled, copiously spotted and blotched with dull olive. Forewing with some slight 
markings at base, especially on costa; two diffuse, ill-defined bars at about one-fifth, from costa to M, the outer joining the median band; a diffuse, 
ill-defined, interrupted broad band somewhat before middle, its anterior half consisting of a costal mark and an ovate, white surrounded blotch, bounded 
posteriorly by M, its posterior half somewhat broader, some clouding following between M! and M?, some spots between the radials, distal area with some 
costal marks and some subterminal blotches between the radials and at tornus. Hindwing with a small blotch at end of cell, irregular interrupted lines 
proximally and distally to this; an interrupted dentate line at about two-thirds, nearly parallel with termen; a subterminal band, or series of blotches, 
somewhat interrupted from R? to near tornus. Underside white, unmarked, costa of forewing narrowly ochreous-tinted, more broadly so at base. Entebbe,
