!'<''<. Protoparce bergi spec. nov. (I'l. V. f. 8, S). 



c? ? . ]5o(ly and \vinj;s greyish civsuuy huff, dusted with brown and ochreous 

 scales. Pali)iis bhick 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 witli buff; first protarsal segment with i)rolonged spines, externo- 

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



^Vings, uiipevshle. Forewing with black dentate lines, four between base and 



aj)ex 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 equidistant lines on disc, the proximal one generally 

 more strongly pronounced ; a postdiscal line of lunules, sometimes v(,'stigial, aud 

 a series of more or less vestigial, submarginal, reversed lunules, the obli([ue apical 



line vestigial or absent ; no stigma ; fringe butf, with small brown dots. Hind wing: 



blackish brown, a costal sjjace (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. 



Underside slightly pinkish. Forewing : much more shaded with brown than 



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



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

 absent; a brown, ill-defined, broad submarginal band. 



S. Sexual armature very similar to that of P. _/lorestan, the tenth sternite 

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

 u})per margin rather heavy, the stronger ones bearing mostly one or two small ones. 



Length of forewing : 45 — 47 mm. 



Early stages not known. 



Hah. Tucnman, Argentina. 



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

 (type : jasmineuruin). 



S ? . Differs from Protoparce in the comb of long liristles of the midtarsus 

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

 Head smaller in ? than in <? , as is the case in many Protoparce. 



Pulvillus and paronychiura })resent, this with one lobe on each side. 



The tyjie-species agrees almost in every detail with Protoparce Jlorestan, of 

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

 comb there is indeed very little by which to Aiaiingmih jasminearum from Jloresta/i. 

 The gap between Ckl. undata and jasminearum is by far larger than the gap 

 between jasminearum and Protoparce. florestan. Nevertheless, G/daenogramma is 

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