 LIFE HISTORY. 



Eggs are deposited mostly singly, occasionally two together ; 

 about .5 mm. long, roundish-ovate, flattened below where in con- 

 tact with surface of object, convex above and coarsely reticulate. 



They hatch in a few days. The freshly hatched larvae are 

 about I mm. long, pinkish with black head and cervical shield. 



The full-grown larva (Plate III, Fig. 11) is about 7-8 mm., 

 pinkish except head which is pale brown, and cervical shield 

 which is dark brown ; tubercles concolorous, ii wider ai)art than 

 i, iii above spiracle, iv -|- v below. 



The larva pupates in a whitish cocoon amongst the frass where 

 it has fed. The pupa (Plate III, Fig. 10) is 4-5 mm. uniform, 

 medium brown ; wing-cases and antenna-cases extend to apex of 

 sixth abdominal segment; abdominal segments apparenth' im- 

 movable ; terminal segment with numerous slender hooked bristles, 

 a few also on the two preceding segments. The pupal period is 

 eleven to thirteen days. 



FAMILY PHYCTTIDAE.

 (Plate IV. Figs. 4-7.) 



This moth witli wings spread is 14-16 mm. long; grey, thickly irrorated 

 with fnscons. Palpi grey, pale fuscons on onter side of second and third 

 segments. Antennae pale grey. Head, thorax, and fore and mid femora 

 with more or less crimson tinge. Abdomen pale grey brown. Fore- 

 wings grey, thickly irrorated with fu.scous, more or less snft'usion of 

 crimson at base, on basal half of costa, and on inner margin, also beyond 

 the cell where it is sometimes confined to the veins; lines obsolete; some- 

 times a dark fuscous discal dot, and one or two dark fuscous discocellular 

 dots: cilia grey-fuscous, darker at base. Hindwings pale and snl)hya- 

 line, darker on veins, apex and hind margin ; cilia whitish-grey. 



The larvae of this Phycitid moth were first noticed in 1905 ; on 

 sorghum, cotton, and sugar cane. In each case, the plants were 

 considerably attacked by A])his. On stigar cane they often hide 

 within a retreat made by the margin of the leaf being rolled down 

 and fastened beneath with silk. Often several larvae may be 

 in the saniie place. Thev eat ofif the substance of the leaf, leaving
