NOVITATES ZOOLOGICAE XXII, 1915. 331 



spot roundish, black, abnormally large for the genus, its diameter nearly 1 mm. ; 



fringe concolorous. Hindwing with termen entire, not appreciably bent at R^ ; 



like forewing. 



Uiider-snrface similar, costal edge of forewing deeper ochreous, cell-marks 

 narrower. 



Abanga River, Gaboon, October 1907 (Dr. Ansorge). Type in coll. Rothschild. 



44. Acidalia macrocelis sp. nov. 



cJ?, 21 mm. Face and npperside of palpus black; vertex black. Antenna 

 with joints projecting, ciliation in S rather long, in ? very short ; ochreous, proxi- 

 mally dark-marked above. Collar deep yellow. Thorax and abdomen bright 

 yellow above, duller and more ochreous beneath. Hindtibia in <? thickened, with 

 hair-pencil and with fringe of projecting scales on upper side ; tarsus about 

 one-half length of tibia. 



Forewing rather broad, apex not very acute ; bright yellow, slightly mixed at 

 base with purple-fuscous ; lines obsolete e.xcept at hindmargin, where they are 

 represented by purple-fuscous spots ; antemedian at one-third or rather before, in $ 

 slight, ending about at fold, in ? stronger, nearly reaching M ; postmedian at 

 two-thirds or rather beyond, forming a large roundish or oval blotch which crosses 

 JP and reappears as a small dot (in the ? larger) on M' ; discal dot small, purple- 

 fuscous ; costal edge distally and fringe deeper yellow, the latter becoming more 



rufescent at tips. Hindwing with termen appreciably bent (rather roundly) at 



R' ; concolorous with forewing ; a small purple-fuscous spot (or thick line) from 

 inner margin before two-thirds to M^ ; discal dot and fringe as on forewing. 



Both wings beneath slightly paler yellow, unmarked. 



Bitye, Ja River, Camerooas, type and another c? ; Fort Crampel, French 

 Congo, a ? ; all in coll. L. B. Front. 



Advocates of " emendation " are asked to note that this species is named from 

 the blotch on the forewing, not from the thickened tibia. 



45. Acidalia omnisona sp. nov. 



c?, 17 mm. Face and jjalpus red. Vertex grey. Antennal shaft grey, dotted 

 with red ; joints slightly projecting, ciliation rather long (a little damaged). 

 Thorax and abdomen pinkish grey, abdomen with a row of deep black dorsal spots. 

 Legs grey, foreleg partly reddish on upper and inner sides ; hindtibia rather long 

 and dilated, with hair-pencil, tarsus about half as long. 



Forewing with apex acute, termen oblique, rather straight, with the faintest 

 concavity in anterior part and conve.xity in middle ; pale pinkish grey (or violet- 

 grey), with a few scattered black scales, extreme costal edge dark red-brown ; lines 

 fine, brownish, accentuated by black dots on costa and (except the median line) on 

 veins ; first at about one-fourth, nearly parallel with termen, slightly sinuous ; 

 median beyond middle, slightly sinuous, in posterior half forming a deep sinus 

 inwards and becoming thick and black and bounded distally by a large reddish 

 brown spot ; postmedian from almost four-fifths costa to hindmargin close to tornns, 

 twice sinuate inwards, followed at toruus by a small blackish spot ; a small black 

 cell-dot ; terminal line somewhat crenulate, blue-grey, almost entirely covered with 

 dense, deep black irroration ; proximal half of fringe tinged with glossy blue-grey 

 and bearing black dots opposite the veins, distal half ochreous-brownish.
