distancefromba.se; the broad, rounded spaces between crossed by nearly equi- 

 distant low ridges; micropyle in the middle of three rows of small rounded cells, 

 outside of which are rings of cells of irregular sizes, mostly live-sided ; color 

 yellow. (Figs, a, a^.) 



Young Larva. — Length at 12 hours from egg .07 inch ; cylindrical, stoutest 

 in middle, the last segments tapering rapidly; color dull green, translucent; 

 marked by eight longitudinal rows of dark subtriangular tuberculous spots, three 

 being above the spiracles on either side, and one below ; these spots are flat and 

 bear small conical tubercles, those of the upper, or dorsal, row two, of the next 

 two rows, one, of the infrastigmatal row four, and each tubercle gives out a long 

 tapering clubbed hair; on 2, on either side, is a large spot, corresponding to the 

 spots of the upper two rows of other segments, and bearing three tubercles and 

 hairs ; the dorsal spots are near the front of the segment, the subdorsal beyond 

 the middle to the rear, the lateral a little in front of the middle, and the lowest 

 row on the middle ; under side, feet and legs green ; head a little broader than 2,
