00. Protoparce bergi spec. nov. (PI. V. f. 8, S). 



<J?. Roily iiiul winj;s greyish creamy l)nff, dusted with brown and orhreous 

 scales. Palpns black at eye ; head and thorax without markings ; abdomen with 

 small black lateral patches on segments 2 to 4 ; tibiae darker than sterna, tarsal 

 segments tipped with bntf ; tirst protarsal segment with prolonged spines, externci- 

 apieal spines of following segments also long, but not stout. With pulvillus. 



Wings, tij>pcrside. Forewing with black dentate lines, four between base and 



apex of cell, the first and second incomplete, interrupted, indicated by spots, of 

 which the costal ones are the most conspicuous, the third and fourth line geminate, 

 curving costad in front ; three eijuidistant lines on disc, the proximal one generally 

 more strongly prononnced ; a postdiscal line of lunules, sometimes vestigial, and 

 a series of more or less vestigial, submarginal, reversed lunules, the oblique apical 



line vestigial or absent ; no stigma ; fringe buff, with small brown dots. Hindwing: 



blackish brown, a costal space (covered by the forewing), an ill-defined anal area, 

 extended along abdominal margin to base and also along distal margin, creamy 

 buff, two black discal lines, curved before anal angle, more or less indistinct ; fringe 

 as on forewing, dots indistinct or ill-defined. 



L'ndcrsulc slightly pinkish. Forewing : much more shaded with brown than 



upperside, traces of three discal bands. Hindwing paler than forewing, a blackish 



band just beyond end of cell followed by two other bauds, the middle one often 

 a1)sent ; a brown, ill-defined, broad submarginal band. 



S. Sexual armature very similar to that of P.Jlorestan, the tenth sternite 

 more deeply sinuate, the harpe less rounded, being longer basi-distally, teeth of 

 upper margin rather heavy, the stronger ones bearing mostly one or two small ones. 



Length of forewing : 45 — 47 mm. 



Early stages not known. 



Ilab. Tucnman, Argentina. 



We name the species in memory of the late Professor Carlos Berg.

S ? . Differs from Protoi>arce in the ('omb of long bristles of the midtarsns 

 being absent or consisting of one or two reduced bristles, and in the smaller eyes. 

 Head smaller in ? than in S , as is the case in many Profopaire. 



Pulvillus and paronychium jiresent, this with one lobe on each side. 



The type-species agrees almost in every detail with Protoparce Jforestan, of 

 which it is a northern develojiment. Apart from the absence of the mesotarsal 

 comb there is indeed very little by which to distinguish /V^«««///(Y(/'»« from //orrsfnit. 

 The gaj) between (7i!. xnuhita and jaHinineariim is by far larger than the gap

 a step forward on the path of the reduction of organs. It is in our opinion a valid
