22. Hemerophila ochriplaga spec. uov. 



?, 50 mm. Structure of H. serrataria Walk. {List Lep. Ins. xxi. 412). from 

 Natal, but much larger, costal margin of forewiug rather straighter, apex more 

 pointed, distal margin more oblique, distal margin of hindwing still more strongly 

 dentate. Ovipositor strong, exserted. Head and bod) 7 concolorous with wings, the 

 face and palpus more infnscated. 



Forewing with SO 1-2 coincident ; light ochreous brown, clouded over almost 

 throughout with dull grey, leaving clearer the margins and especially a subquadrate 

 spot of 2-3 mm. diameter between SO 6 and R 1 just proximally to the snbterminal 

 line ; lines fine and not very conspicuous, blackish ; antemedian from one-third 

 costa, curved in cell, becoming strongly oblique inward and slightly sinuous, reach- 

 ing hindmargin at one-fifth ; postmedian oblique inward from seven-ninths costa, 

 very shallowly sinuate inward before and behind SC 5 , forming an almost rectangular 

 projection at R 2 , a long, very shallow sinus inward between R 2 and M 2 , and a 

 deeper sinus inward between M 2 and SM 2 , reaching hindmargin at about two-fifths ; 

 faint indications of a dark median shade and of some dark shading proximal to 

 the indistinct, pale, lunulate-dentate snbterminal line ; terminal dark line weak, 



interrupted ; fringe narrowly clear at base, otherwise with dark irroration. 



Hindioing less suffused, except in distal area ; median shade faintly indicated ; 

 postmedian line fairly strong, very feebly crenulate in places, approximately 

 parallel with termen except towards abdominal margin, where it bends towards 

 the tornus. 



Underside duller, almost without markings, except that both wings show a 

 rather elongate, ill-defined cell-spot, strongest on the hindwing. 



Oubangui-Chari-Tchad : Bangui. Type in coll. L. B. Prout. 



A ? from Bitye, Ja River, Cameroons, too damaged to describe, has long stood 

 in my collection ; except that it is slightly smaller (46 mm.) and has stronger 

 terminal line on both wings, it agrees excellently with the type. 



23. Ectropis amphitromera Prout 



This species was described (Ent. xliv. 294) from the ? . I have now seen the 

 c? from Bitye, Ja River, Cameroons, and am able to confirm its showing the usual 

 8 characters of Ectropis. The antennal ciliation is sessile, of about the length of 

 diameter of shaft, the spine over basal cavity of abdomen strong. The abdomen 

 is slender and markedly elongate, extending well beyond the hindwing. 



24. Myrioblephara prospila spec. nov. 



(J, 23 mm. Face whitish. Palpus rather short ; fuscous, whitish beneath. 

 Antenna not dentate, the ciliation about three times as long as diameter of shaft. 

 Crown whitish. Collar more brown. Thorax whitish, above strongly mixed with 

 fuscous. Abdomen mostly whitish, with an interrupted dark belt on second tergite* 

 Foreleg somewhat infuscated, except at ends of joints ; hind tibia not dilated. 



Forewing with fovea strong ; SC 1-2 coincident ; whitish, with scattered dark 

 fuscous irroration; lines dark fuscous, in part mixed with black, arising from black 

 costal spots; antemedian from beyond one-fourth costa, slender, somewhat curved, 

 angled inward in front of SM 2 ; median proximal to middle of wing, traversing the 

 cross-vein, deeply incurved between M and M 2 (retracted to their junction), thick
