subventral space contracted. Skin smooth, shining. Sub- 

 dorsal horns on joints 3 to 13, those of 3, 4, 5, n and 12, not 

 much larger than the others, but stouter and thicker, perhaps 

 half again as long ; that of joint 13 more remote, directed back- 

 ward ; lateral horns on joints 3, 4, 6 to 12, subequal, those of 

 3 and 4 slightly stouter. All horns thick, conic, blunt, rather 

 short, each with three fine, stiff setae radiating from the apex. 

 The horns are separated from each other by a space equal to 

 their own diameter. Color ocher yellow, the horns a little 

 whitish ; segmental incisures marked by grooves that appear 

 somewhat more transparent than the rest of the larva. Length 

 1.4 mm. The horns and setae are distinctly seen before the larva 

 is out of the shell. No sign of eversion as in the larvae with primi- 

 tive first stage. Head small, round, eye black, mouth brown, 

 labrum and labium prominent. The larvae congregated in a mass 

 and molted without feeding. Duration of stage three days. 



Stage II. Somewhat shorter and squarer, elongate ellipti- 

 cal, sides parallel, dorsal and lateral spaces even, broad, the 

 dorsal flat, or like the lateral, a little concave. Horns large 

 and thick, but not very long, not much over as long as thick. 

 Subdorsals of joints 3 to 5, n, 12 large, 6 and 10 small, 7 to 9 

 equal, small, but larger than those of 6 to 10 ; 13 small, about 

 like those of 6 and 10. Laterals all moderate, 3 and 4 scarcely 

 larger than the others. All densely covered with black-tipped 

 yellow spines. Cervical shield large with many setae anteriorly, 

 contracted. Subventral space small. Segmental incisures well 

 marked ; a groove in the center of each transversely in the dor- 

 sal space, divided on the dorsal line, apparently representing 

 depressed spaces (i). Whitish yellow, the horns clear yellow ; 

 no marks. Skin extremely finely shagreened, reticulate with 

 light lines under a high power like that in the early stages of 

 Natada nasoni. The larvae fed gregariously, eating the paren- 

 chyma. Length 1.4 to 2.2 mm. 



Stage III. Somewhat flattened, like Eiiclea dclphhiii. 

 Rounded, distinctly elliptical, the sides no longer parallel, but 

 convex, ends rounded ; dorsal and lateral spaces broad sub- 

 equal, flat, dorsum arched a little, sides narrowing at the end> ; 

 subventral space small, contracted. Subdorsal horns of joints 

 3 to 5, ii and 12 stout, conic, rather long, fully twice the
