Anthocharis Genutia, Fabricius ; Edwards, But. N. A., II., p. 83, pi. 17. 1878. 



Egg. — Long, narrow, thicke.st in middle, curving moderately towards the base, 

 which is broad and flattened, towards summit more rapidly, so that the upper 

 half is cone-shaped ; the top depressed, the micropyle surrounded by minute 

 irregularly hexagonal cells ; ribbed vertically, the number of ribs about sixteen, 

 half of which reach the summit and curve to the depression, the others ending 

 not much short of summit, the spaces between cro.ssed by numerous fine ridges ; 

 color yellow-green. (Figs, a to a^.) Duration of this stage about four days. 



Young L.\rv.\. — Length .05 inch ; cylindrical, tapering very gradually from 2 

 to 12, curving roundly on dorsum of 13, ending squarely ; color greenish-yellow ; 

 running longitudinally are three rows of rounded tubercules on either side, from 

 each of which proceeds a short straight hair, which tapers from the base, and is 

 thickened at the end, the end usually covered by a globule of fluid (Fig. 6*) ; the 

 tubercles are concolored with body, the hairs light ; on 3 and 4 stand in cross 

 row, sometimes with a little irregularity; after 4 to 12 in triangle, the dorsal 

 tubercle being on the front of the segment, the sub-dorsal on the rear, and the 

 lateral a little before the middle ; on 2 the upper two are near together on the 

 front, and corresponding with the lateral row below is a very small one, and a 

 hair without tubercle close to and under it ; there is also a third one behind and 

 between tlie upper two equal to either in size ; on the front of 13, the three 

 tubercles are in triangle as with the preceding segments, and at the rear is a 

 cross row of four, the two middle ones being dorsals, the others smaller and 

 apparently of the lateral rows ; at the extreme end, on either side a small 

 tubercle ; along base a row of short hairs, two on 2, and from 5 to 12 ; one on 

 13, and on 3 and 4 one each, from a tubercle ; head a little broader than 2, 

 sub-globose, depressed at top ; on each lobe three tubercles like those on body
