Four fully thrown larvfie are preserved. The head is elliptical, 

 hij^hor than wide, scarcely l)ilol)ed, smooth, black with a few faint 

 whitish reticuhited lines, of which one straig'ht across the front above 

 clypeus is most distinct. Body cylindrical, smooth, slightly tapered 

 at the end. Cervical shield laroe, dull l)lack, quadrate, bisected; 

 thoracic feet, abdominal foot shields and anal plate likewise black, 

 l^ody dark brown with numerous pale yellowish lines. These are 

 dorsal, addorsal (tubercle i), upper subdorsal, lower subdorsal (tul)er- 

 cle ii), upper lateral, lateral (tul)ercle iii), stigmatal (tul)ercle iv), 

 up})er su]>ventral (tul)ercle v), lower subventral (tubercle vi), the lines 

 more or less tlexuous, sliuhtly anastomosed, the subventral ones more 

 irregular and confused. Tu))ercles single, small, dark, with long 

 coarse white setie; on the abdomen i dorsad to ii, iii suprastigmatal, 

 iv stigmatal posterior, v subventral, vi lower subventral, normal; a 

 hair on the leg shield. On the thorax ia to iib separate, nearly equally 

 spaced, iib rather smaller; cervical shield covering all the six hairs. 



The cocoon is a tough, silken sack, cylindrical, sharply compressed 

 at the front end, with an open slip for emergence, covered by loose 

 silk. 



The pupa is thick and robust, ])rown, entirely without cremaster, 

 the abdomen l)luntly rounded with a ring of elongate punctures. 



These structures indicate an affinity with the Njxteolidse.

The larva is a large haii-y Arctian of the shape of the North American 

 Ext/gviene acraea Drury, lightly colored as in pale specimens of D'ai- 

 rrisla rlrginica Fabri("ius. The head, thoracic feet and abdominal leg 

 plates are ])lack. Body immaculate, except for broken 

 mottled dark subdorsal and substigmatal stripes. 



DIACRISIA IMPARILIS Butler.

Food plant: Jlorus alha. 



The eggs are laid in a patch covered by the brown- 

 ish wool from the abdomen of the female moth. 



The larviB resemble those of ArslIoncJie alhorenosa 

 in color, being ])lack with yellow spots and red warts. 

 The hairs are black and white, rather thin and do not 

 obscure the body coloration. Head rounded, bilobed,
