10 Dr. F. A. Dixey on 



A male Pieris was captured by Dr. G. B. LongstafE, at an 

 elevation of about 1300 ft., between Zigzag Station and the 

 port of La Guaira, Venezuela, on March 29, 1907. This 

 capture is recorded in his book, " Butterfly Hunting in 

 Many Lands," 1912, p. 320, and the specimen is well figured 

 on Plate III, figs. 1, 2 of the same volume. At the same 

 place, on January 11, 1913, Dr. Longstaff caught, together 

 with specimens which appear to be referable to P. sevata, 

 Feld., a female Pierine which I beheve to be conspecific 

 with the male above mentioned. These two specimens 

 were referred to by me in Proc. Ent. Soc. Lond., 1913, pp. 

 cxiii, cxiv, and are here described under the name of Pieris 

 janeta. 



5. Pieris janeta, sp. n. (Plate II, figs. 5, 6.) 



(J. Exp. al. 62 mm. Upperside white with a slight but 

 distinct greenish tinge. A slight fuscous edging to the costal and 

 posterior margin, expanding somewhat at the apex, and prolonged 

 nearly to the anal angle. A somewhat paler fuscous streak fills 

 the space between the costa and costal vein for about two-thirds 

 of the distance from base to apex. Fore-wing otherwise im- 

 maculate. Conspicuous streaks of roughened texture, dead white 

 in colour, accompanying both sides of the submedian vein, of 

 the median trunk from the origin of its first branch to that of its 

 third, and of the median branches themselves. They are also 

 found on both sides of the lower, and on the inner, or posterior, 

 side of the upper radial and of that part of the subcostal trunk from 

 which the upper radial originates, on the outer side of the two disco- 

 cellular veins, and finally as a small patch iii the upper and distal 

 angle of the cell. The streaks generally fuse together at the root of 

 each interspace, but in the interspace between median and sub- 

 median they remain distinct, neither streak reaching inwards as far 

 as the median trunk. Hind-wmg immaculate; roughened streaks 

 like those on the fore-wing accompanying the subcostal and median 

 veins. Third branch of subcostal in fore -wing very short. 



Underside : fore-wings generally dull white ; dead white where 

 the roughened streaks show through from the upper surface. Apex 

 and costa pale ochreous. Hind-wings uniformly ochreous, of a 

 somewhat deeper shade than the apex of the fore-wing; a fuscous 

 spot, like that in the female, occupymg the angle between the lower 

 discocellular and third branch of the median vein. The costa 

 thinly edged with bright yellow ; a minute spot of the same at the 

 root of the subcostal vein.
