FORTT-SECOND REPORT ON THE StATE MuSEUM.

verse markings on the obscure annulets; the dorsal black patch on 

 the eleventh segment; an interrupted subdorsal black line consisting 

 of a black streak on the posterior half of each segment; the stig- 

 matal line of black crescents and the substigmatal line of a yellowish, 

 approaching orange, color. The spiracles are small and black. One 

 of the paler colored lai'vse is represented at a in Figure 17. 



At maturity. — By the thirtieth of May, many of the larvse had ceased 

 feeding and had evidently matured. The following day they were 

 transferred to a box of earth upon which a layer of plantain leaves 

 had been placed. When examination was next made on the third of 

 June, a little feeding had been done. Four-fifths of the larvfe were 

 found above ground, and the rest had buried themselves at different 

 depths — some just beneath the surface, showing a slight contraction 

 in length, indicating progress toward puj^ation. A few that had been 

 transferred to a separate box with food, were still feeding on June 

 fourth. 



The Pupa. — On the fifth of June, three newly-disclosed pupse were 

 found beneath leaves on the surface of the ground — at first of a 

 dull pale yellowish color, but later becoming mahogany-brown. The 

 anterior segments following the rounded head-parts are cylindrical 

 for the extent of the wing-covers, while the remaining six free 

 segments rapidly diminish in size to the anal tip, which is armed with 

 a single short, black, curved spine. The anterior margin of the 

 segments is brown and closely punctated. Length, 0.7 inch ; 

 greatest breadth, 0.2 inch. 



27ie Moth. — The first moths — eight in number — emerged from 

 their puj)0e on the twenty-fourth of June, and on the following day 

 eighteen others made their appearance. The duration of their pupal 



stage would thence have been 

 twenty days, and their larval 

 stage twenty-eight days. The 

 last of the moths, 150 in all, 

 were given out on June thirtieth. 

 The species proved to be ver^- 

 easy to rear, unlike most of the 

 cut-worms — hardly any fatality 

 attending any of the several 

 transformations. The moths 

 displayed a remarkable absence 

 of timidity on being disturbed. 

 With hardly any motion beyond 

 the necessary readjustment of 

 their legs, they could be lifted from the ground upon which they rested
