 The 3rd vein begiAs at one-third of the wing, runmng straight to 

 S A^Tnt-ti^he^nterior cross-vein placed at its basal angle ; the 

 4 h vein forks just beyond the fork of the 2nd longitndn.al, its 

 branches being parallel ; 5th vein straight, ong; bth sinaous, 

 lo\io Basal cell nearly one-third the lengtli of the wing. Scales 

 arhresent at the base of the wing only, the whole wnig having 

 an iddescent silvery grey appearance, though the coloiu- may be 

 best described as snioke-grey; in many specimens the wmgs are 

 p?acSy clear, with pale brownish yellow or ye llo..sh grey 

 hLiJs arranged in the usual divaricate method along all the veins.

Types in the Indian Museum. c f ^ 



This species is easily distinguished, except m the case of females 

 distended with blood, from all other Indian forms by the strong 

 contiast in colour between the dorsal surface and the sides of the 

 thorax In P. liimalayensis the thoracic dorsum is darker than 

 the sides but the difference is not at all so conspicuous as in the 

 present 'species. It is found in Calcutta throughout the year 

 but'at times is much more abundant, apparentl.y favouring dark 

 spots in the basement of houses and bathrooms, being also often 

 attracted at night by the light of a lamp. 



Var. marginatus, Ann. 



9 Body rather darker than in P. zeylanicus. 

 Leas ■ the hind leg is less that two and a half times as long as 

 the thorax and abdomen; its femur about half as long as its 

 tibia of the same length as the metatarsus, which latter is equal 

 in length to the rest of the tarsus ; coxie and femora rather bright 

 shining pale brown. Wmcjs with the 1st longitudinal vein ending 

 some itttle way before three-fourths of the wing; 2nd longitudinal 

 vein forking distinctly before tlie middle of the wing the 

 anterior branch forking distinctly beyond it: 4th longitudinal vein 

 forking almost exactly at the middle.

Althoucrh only a solitarv specimen is known, this variety is 

 apparently a good one. The venation is rather hke that of the 

 tvpical form of P. anjeniipes, but the upper branch of the 2ncl 

 longitudinal vein forks distinctly before the tip of the 1st vein, 

 instead of approximately below the tip ; the wing also is narrower. 



* The fork of the upper branch of the 2nd longitudinal vein is sometimes 

 considerably more basal than shown in Dr. Annandale's figure, and the wmgs 

 are not infrequently much less broad.
