POLIA CHI. 17 



When full-fed the larva makes a decided cocoon 

 under the surface of the soil, of bits of earth some- 

 what toughly spun together ; the pupa is nearly six- 

 eighths of an inch long, smooth and regular in out- 

 line, tapering gently to each end, the last segment of 

 the abdomen terminating rather bluntly and furnished 

 with a knob, from which is emitted a pair of very fine 

 {quite bristle-like) hooked spines ; the colour of the 

 pupa is reddish-brown, and the surface glossy. (W. 

 B., March, 1873; E.M.M., May, 1873, IX, 290.) 



POLIA ELAVOC1NCTA. 



Plate LXXXVIII, fig. 4. 



On the 9th of July, 1873, I received from the 

 Rev. B. Smith five larvse of this species reared from 

 eggs and sleeved on apricot; they also like mint. 

 Four of them were full grown, the other one half 

 grown. The full-grown larva is an inch and three 

 quarters in length, of moderate stoutness throughout, 

 and cylindrical. The head full, and but little less 

 than the second segment in width ; the segments 

 very smooth and scarcely defined when stretched out, 

 though on the larva turning itself round the skin 

 folds itself afc some of the segmental divisions and 

 then shows distinctly pale yellow in the folds. The 

 ground-colour of one of these is yellowish-green, the 

 others being bluish-green ; a slightly darker dorsal 

 line having a line of minute yellowish dots or specks 

 through the middle of it. The spiracular line is dark 

 or blackish-green and is but the mere edging to the 

 yellowish- white subspiracular stripe which melts away 

 gradually below into the green of the belly. The 

 spiracles are white, outlined with black. The ventral 

 surface is green, same as the back, and has a central 

 faint whitish stripe. The legs and ventral and anal 

 legs are unfreckled, but all the rest of the green 

 ground, excepting the head and a smooth velvety
