towards >>(.'■'. liiiKhviiiu; : dirty wodd-bniwii, a traci' tit' a thin postdiscal line and 



of a broader siilimarjjinal one, the latter more distinct behind, fringe black at ends 

 of jiosterior veins. 



Utidi'i-xitk. dirty wood-brown, markings inconspicuons. Forewing : a brownish 



black snbapical patch bordered distally by a grey line, this patch extended generally 

 to internal margin, forming an ill-defined submarginal baud, discal dentate line 

 vestigial, a second line nearer cell very feebly marked, costal area beyond cell more 



or less obviously whitish grey. Hiudwing : a discal and a postdiscal dentate line, 



the former at apex of cell ; submarginal area clouded with black scales, costal and 

 abdominal areas more or less whitish grey. 



i. Tenth abdominal tergite (PI. XXV. f. ^'3) subtriangular, broadly rounded at 

 the end ; sternite with a triangular mesial lobe {Xc). Clasper with a subdorsal 

 patch of bristles on the inner surface, the bristles pointing proximad and dorsad ; 

 ape.x of clasper rouuded dorsally, less so veutrally ; harpe (PI. XXXII. f. 19) nearly 

 as in Lfncophh'hia (tfra, reaching almost end of clas])er, with a ventral ])rojection 

 before the apex, which has the shajie of a rounded lobe. Peuis-sheath with a short 

 conical tootli pointing laterad (PI. XXX. f. 4o). 



? . Rather larger than S ; markings more proniunced. 



Length of forewing : S , 23 — 24 mm. ; ?, 3() mm. 



Ilah. Western side of Lnitpold Mountains, near Ikutha, British East Africa.

 Lvuco/ihhbiii 'f, Boisduval, Kjtn}. Gen. Lip. Hit. i. p. 67 (lS7."i). 



$ ? . Tongue reduced to two short lobes or tubercles. Palpus small, but visible 

 from above, rough-scaled, second segment not much longer than broad (scaling 

 included), joint open. (Antennae very different in the two species). Abdominal 

 tergites spinose all over. Tibiae spinose \ foretibia very short, armed at end with 

 long ihoni and a short tooth, spur without distinct fringe ; spurs of mid- and hind- 

 tibia slender, one pair to hindtibia, longer spur not quite half the length of the 

 first tarsal segment, this as long as segments 2 to 4 together ; pulvillns present, 

 paronychium without ventral lobes. Distal margins of wings entire; lower angle 

 of cell of hindwing acute. Clasper and eighth tergite without friction-scales. 



Early stages not known. 



Hah. British East Africa and Abyssinia. 



The two species differ considerably in several respects, and will jiroliably come 

 under difiereut generic terms when better uuiterial oi' /u'l/ffli/ii k at disposal. The 

 I wo individuals of /ie(/y///H' — the only ones known — are so badly preserved that we 

 abstain from making a separate genus for their reception. The differential characters 

 of lif'iijlini and mira are given under the respective species. 



Key to the sjiecies : 



a. Patch of forewing trajieziform, sinuate behind ; 



antenna pectinated 243. C. mira. 



Patch of forewing triangular, not sinuate behind ; 



antenna not pectinaled 244. V.heuglini.
