Comostolopsis gvn. imv. 



Tliis new name is projiosed for a group of small African insects, which at first 

 sight might he taken for species of Comostula Mevr., hut are really quite different 

 in their neural ion. In Coniostohi the discocellular is of a peculiar shape, heing 

 vertical above and below, and horizontal in the middle, the cell therefore being longer 

 at the bottom than at the top; in the African species the discocellular is of tiie 

 usual shape, vertical in the upper third, then concave and oblique; in Cumonloln 

 (as also in Eucrostes, to which these African forms might otherwise be referred) veins 

 3 and 4 of the forewings rise close together from end of cell ; in Comostolopais they 

 are stalked. Palpi slender, porrect, much longer in ? than S ; hindtibiae with 

 four spurs. Frenulum present, but exceedingly fine. 



Type : Cumostolopsis simplex sp. nov. 



15. Comostolopsis coerulea sp. nov. 



Like G. simplex, but the wings narrower, and pale blue instead of green; 

 otherwise not differing, except in being slightly smaller. 



One f?, fom- ? ?, from the Escarpment, British East Africa, .lanuary -March 

 1901 (I)oherty). 



Hi. Comostolopsis simplex sp. nuv. 



Like ('. Klilhirid Keld., but with no deej) red maigiiial line before the yellow 

 fringes; the transverse lines much the same, but entirely without dark dots along 

 their course; cell-spot small, dark; costa finely ochreous. Face and tips of palpi 

 reddish; verte.K pale; thorax and alidomen green. 



L'nder.--i(le pale green, flushed with dull reddish at base of co.sta of forewings, the 

 costal edge in the S behig darker. 



Exijanse of wings : J 20 mm. ; ? 22 mm. 



Six Si, four ? ?, from the Escarpment, liritisli East Africa. January — March 

 1901 (Doherty). 



Larger on the average than C. stiltari(i. 



17. Episothalma subfuscata sp. nov. 



Fomi-iiujs : with basal two-thirds deef) green, marginal area wliitisli ; the green 

 area edged bv a dark fuscous line from costa at four-fifth.s, forming a liidentate 

 jirojection on veins fl and 7, another on veins 3 and 4, and an angle on vein 1 ; the 

 marginal area with a dull rufous cloud along its middle, speckled with black ; costal 

 area broadly rufous, thickly speckled with bl.ack ; a marginal line of shallow black 

 lunules, except between veins 3 and 4 ; fringe pale rufous. 



Iliiuhvings : like forewings, but the dark line edging the green area angled 

 only at vein 6 and sinuous into anal angle ; the central cloud of the marginal area 

 blacker, es|)ecially towards costa. 



l'nder>ide of forewings dark cinereous for two-thirds; the pale marginal area 

 with a broad l)lack cloud; costa ochreous; hindwings with basal area whitish tinged 

 with grey, the edging line thick, .stopping, as well as the black cloud, before anal 

 angle. Face, palpi, and vertex blackish; thorax and abdomen ochreous grey. 



Expanse of wings : 30 mm. 



(hie d from Oguta, Niger, October 1901 (l)r. Ansorgej. 



Allied to E. margimUa W'arr. and seini(jrisea W'arr., but quite distinct.
