6. Ill size and pattern nearest to J', ort/zof/rap/ius R. & J. (lOO:!). Pinkish 

 jirey. A Inown mesial stripe on head and anterior portion of thorax. .Joint of 

 palpns open, second segment rounded off. Tibial s])urs somewhat shorter than in 

 /'. ortlixiqruphus. 



Wings, npperside : forewing with brown lines : a short thin subbasal line, 

 a more prominent line at basal fourtli, cnrving costad, an anteiuedian ilonble 

 line, feeble, bifle.KUOse, curved basad anteriorly and ]iiisteri(irly and in niiiUUc ; 

 interspace between this double line and the preceding one brownish : a small 

 stigma with jiale centre ; an almost straight discal line, a little more proximal 

 at costal margin than the corresponding line of P. orthograjjhtts, followed by a 

 faint erenate line and a .•^ubmarginal line, the latter being straight from costal 

 margin to R^, and faint and flexnose farther back ; hinder angle less prodnced 



than in P. orthoyrnplnis, no distinct black-brown sjiot near this angle. Hindwing 



pinkish drab, deeper in tint than forewing, grey at anal angle ; a trace of a brown 

 median line and of an interrnpted snlianal bar ; fringe dotted with brown. 



L'luh'rside more clayish grey than npper, both wings with a curved discal 

 line and a row of submargiual dots, the" dots of hindwing being replaced near 

 anal angle by a line. 



(Genitalia : tenth tergite broad, narrowed beyond middle, then widening again 

 a little, with an antemedian tubercle at the lateral edge, apex sinuate, the lobes 

 broad, obtuse, somewhat slanting downwards ; tenth sternite divided into two 

 obtuse lobes. Clasper sole-shaped, with large patch of small friction-scales, the 

 eighth tergite bearing laterally on inner surface a band of large friction-scales. 

 Harpe nearly as broad proximally as the valve, and two-thirds the length of tlie 

 same, sinuate at apex, the two lobes short and obtuse, the njiper a little longer 

 than the lower, both denticulate ; dorsal edge of harpe prodnced at base into a long 

 thin process which projects anad. Penis-sheath thin, bearing at apex a long pointed 

 process which lies close on the sheath, being directed proximad.

6. Paljjus closely appressed to the head, second segment much longer tiiau 

 the first ; joint not open. Antenna less deeply grooved than in Lycosphinx 

 \i. it .L (1003); end-segment somewhat siiorter, without long bristles, the scales 

 of upperside iMojecting beyond apex. Posteriorly below eye a tuft of hair-scales, 

 projecting forward, covering half the eye. Abdominal tergites with dispersed flat 

 spines all over, besides the nnmerons spines at the edges. Tibiae spinose, s])urs 

 as short as in Lycosphinx^ one pair to hindtibia, midtibia as long as midtarsiis, 

 hindtibia somewhat shorter than tarsus, but more than half as long again as 

 tirst tarsal segment. 



Neuration as in l.ycosphinx, but SC^ and R^ of hindwing on a shorter stalk, 

 D- shorter, M- less prdximal. Distal margin of forewing dccjily emarginate between
