ARCHA. 81 



pale ochrnceous, base of iibdoiiien black where the segmental 

 margins are gro^yish white; tegmiiia pale, creamy semiliyaline, much 

 mottled with very pale fuscous, three or four linear longitudinal 

 black spots in costal area, apical veins more or less suffused with 

 blackish, three rounded black spots ou basal tliird and three 

 blackish spots on inner margin ; wings white, semihyaline, the 

 veins darker. 



Allied to P. ampUJicata , Dist., from Ceylon, but with tlie vertex 

 of head slightly shorter and considerably more concave ; the am- 

 plified mesonotal margins much broader and less spinous, markings 

 of the tegmina distinct, &c. 



Length excl. tegm. 85 ; exp. tegm, 18 millim.

Type, A. typica, Dist. 



Distrihution. Ceylon. 



Vertex of head long and narrow, projecting considerably beyond 

 eyes, moderately widened posteriorly, notched at apex, the lateral 

 margins strongly ridged ; face long and narrow, the lateral mar- 

 gins ridged, a little ampliated. before clypeus, which is centrally 

 ridged and much shorter than face ; autennoe inserted just before 

 base of clypeus, long, second joint very robust ; rostrum reaching 

 the posterior coxce, apical joint of moderate length ; legs mode- 

 rately long and slender : pronotum sliort, angularly sinuate, its 

 lateral margins foliaceoi:sly produced, its posterior margin ridged; 

 mesonotum long, somewhat obscurely tricarinate ; tegmina narrow 

 at base, broadened towards apices, apical areas numerous, short, 

 extending from posterior angle of inner margin to apex of costal 

 margin ; costal area wide, without transverse veins, costal margin 

 siuuate a little beyond base. 



By the strongly developed, antenna) Archa, in this fauna, is 

 allied to Vhiata and Devadanda, and by the structure of the 

 autenusB more to Vinata; the position of their insertion, the 

 structure of the face, and the single series of transverse veins 

 to the apical areas of the tegmina will, however, prevent any con- 

 fusion. It is more nearly allied to the Australian genus Xtiranda,

Head, pronotum, and mesonotum ochraceous ; a lateral fascia 

 on each side of mesonotum black ; central area of face, eyes, and. 

 antennae black; sternum and legs piceous ; abdomen beneatli with
