less brown in irregular patches (Figs./ to/'') ; head small, obovoitl, dark brown, 

 glossj^, placed on the end of a long, conical neck, which can be thrust out to a 

 length equal at least to the breadth of two of the body segments (Figs. P-l''), and 

 when withdrawn is, together with the head, completely within segment 2 ; color 

 of neck blue-green. (Figs, i, l\) The surface of the body is velvety, and this ap- 

 pearance is owing to minute stellate glassy processes, scarcely raised above the 

 surface, and only visible under a powerful magnifier, mostly six-rayed, and each 

 sending up from the centre a filament whicli is a little longer than one of the 

 rays ; these stars are arranged in pretty regular rows, and are light except when 

 on brown ground, in that case brown ; but in the fall larva3 the stars on brown 

 ground are observed to be sometimes pink. (Fig. n.) On 11 near the posterior 

 edge, on middle of dorsum, is a transverse wavy slit, in an oval raised rim, out of 

 which, at the will of the larva, is protruded slightlv an ovoid green membrane 

 (Fig. k) ; and on 12, back of and outside the stigmata, is a mark like a stigma 

 on either side, but a little lai-ger ; from this, also at will, may proceed a mem- 

 branous cylinder, the top rounded, truncated, and turned in, but which, wdien 

 fully expanded, displays a crown of tentacles. (Figs. ;u-Hr.) 



Before pupation, the larva sometimes changes color to pink, and from pink to 

 brown, or becomes brown without the pink stage ; others retain their natural 

 hues, but these fade. From fourth moult to pupation, 5 or G da vs. 



CiiUYSALis. — 5 from eggs of Vlolacci: average length, .2Go inch; breadth 

 across mesonotum, .O'JIG inch; across abdomen, .123 inch. 

 27 from eggs of Pseuddrtjtohis : average length, .318 inch; breadth across meso- 

 notum, .119 inch; aci'oss abdomen, .159 inch. 

 25 from eggs of Negledn of July : average length, .298 inch ; breadth across meso- 

 notum, .1 inch; across abdomen, .14 inch. 

 3 from eggs of Ncjjlecta of September : average length, .293 inch ; breadth across 

 mesonotum, .1 inch; across abdomen, .136 inch. 

 The ventral side straight, the dor.sal rounded, and evenly, except for a slight 

 depression below mesonotum, the abdomen broad and high ; head case narrow, 

 rounded at top; mesonotum somewhat prominent, rounded ; color dark brown or 

 yellow-brown, varying ; the wing cases dark, and sometimes green-tinted ; on ab- 

 domen two sub-dorsal rows of blackish dots, and sometimes a medio-dorsal dark 

 line from end to end (Figs, j/, Pseudarrjlolus, h, Violacea, nat. size) ; surface 

 covered with short fine hairs. (Fig. /.) Duration of this stage, in the brood 

 from Violacea, in the only instance in which a butterfly has emerged, 24 days, 

 most of the chrysalids hibernating; in the brood from Nerjlecta of July, 10 and 

 11 days, with irregular disclosure for some weeks after, most chrysalids hiber- 

 natinir.
