Five S (S from the Escarpment, British East Africa, Decenilier 1900 — March 

 1901 (Doherty). 



Consistently smaller than T. nigrihasis and distinguished at once by the vellow 

 iiindwings. In none of the five examiiles is the abdomen of the cj elongated as iu 

 iii(/rihi(sis. The markings of the forewings, however, are in the main almost exactly 

 tiie same as in nifjribasis, and I am by no means sure that, different as its superficial 

 appearance seems, this may not turn out to he a form of the <? of that insect. This 

 suggestion is rendered more prolialile by the fact tliat in the B. M. collection there is 

 a single cJ, which, while possessing the yellow Iiindwings of seinijlavata, has the 

 forewings exactly the same as the alierration cariie(C of nigrihasis. 



Subfamily TRU'HOPTERYGIDAE. 

 Lobidiopteryx gen. nov. 



Foreinmjs : large; eosta curved ; hindmargin curved, longer than inner margin' 

 below almost parallel to costa. 



Hindwinijs : small; both angles rounded; hindmargin curved; a small simple 

 lobe at base of inner margin. 



Abdomen elongate, especially in S ; antennae ligulate, with acute apex; palj)! 

 short, stout, porrect, rough-haired ; forehead slightly projpc(ing : tongue and frenulum 

 present; legs long; hindtibiae of i with two spurs, and a lung tuft of hair from 

 femoro-tibial joint. 



Neuration : forewings, cell more than half as long as wing; discocellular oblique ; 

 first median nervule at one-half, second at nine-tenths, the median upbent beyond it ; 

 lower radial from u]iper third of discocellular, upper radial stalked with 7, 8, 9 ; 

 10 and 11 from cell, 10 anastomosing with 11 and again with 8, 9, forming a double 

 areole : Iiindwings,- costal united by bar with subcostal at end of cell in (?, anasto- 

 mosing for two-thirds of cell in ? ; 6, 7 very shortly stalked ; radial from upper 

 two-thirds of discocellular ; medians as in forewings in cJ ; in ? the first median at 

 four-fifths, and the internal vein present. 



Type : LobidiujAeri/x veninofftla. 



61. Lobidiopteryx veninotata sii. nov. 



Forewings: pale, varied with dull green and ro.sy brown; the lines blackish, 

 and in many places, where they cross the veins, expanded into black dashes ; all wavy 

 dentate; basal patch with three or four indistinct lines, Init all expanded on inner 

 margin to form black dashes, the edge running from one-fourth of costa (o middle 

 of inner margin ; central fascia broad on costa, formed of two dark bands, the inner 

 consisting of two, the outer of three waved lines, the latter running to anal angle ; all 

 the five sinuous, outcurved above and incurved below, especially the outer three ; pale 

 hand preceding and following central fascia narrow, with a darker traversing line; 

 submarginal line pale, rarely distinct, jireceded by a doulile waved line, which forms 

 a dark spot beyond cell, and followed by a dark brown or green marginal band, 

 containing wedge-shaped black dashes at the vein ends, meeting each a pair of 

 black marginal spots; fringe pale, mottled dark beyond veins; cell-spot oblique, 

 blackish. 



Hindivimjs : whitish ochreous, sufl'used with grey towards hindmargin ; fringe 

 pale with dark dots; marginal spots as in forewings; in perfect examples the veins
