16 Psyche [February 



Percnoptilota fluviata Hbn. 



The larval stages of this species have already been recorded 

 by Doctor Dyar (Psyche 1899, p. 429). Larvae reared from ova 

 by us offer considerable differences to those described by Doctor 

 Dyar; we therefore publish our notes for the sake of recording the 

 larval variation. 



Ovum. Pale yellow when first laid, turning later darker; oval, with flattened 

 micropylar end; faintly sculptured with regular hexagons. Length .5 mm. Dura- 

 tion of egg stage 7 days. 

 Stage I. 



Entirely dull gi'eenish black, head slightly reddish. Length 2 mm. 

 Stage II. 



Head slightly reddish; body greenish white with faint traces of geminate dorsal 

 and subdorsal lines; abdominal segments with rather diffuse lateral purplish patches. 

 Length 6 mm. 

 Stage III. 



Head light greenish, mottled with reddish. Body green with geminate light 

 yellow dorsal stripe tending to diamond-shaped enlargements on segmental inci- 

 sions; two dorsal yellowish lines; lateral portions tinged with reddish-purple which on 

 abdominal segments forms indistinct transverse bands across the body at jimction 

 of segments, lateral portion usually contains a dark streak. Beneath yellowish- 

 green. Length 9-10 mm. 

 Stage IV. 



Color and markings very variable — green to reddish brown, head whitish, striped 

 and sprinkled with reddish; indistinct geminate dorsal and subdorsal stripes; the 

 abdominal segments are crossed by 5 purplish intersegmental bands, most distinct 

 in the green larvae; laterally these bands are often terminated by a blackish longi- 

 tudinal dash. Tubercles small, white; claspers usually marked with purplish. Be- 

 neath segmental divisions frequently marked with yellow. Length 19 mm. 



Food plant, Rumex. 



Tornos scolopacinarius Gn. 



Stage I. 



Head deep brown, sprinkled with white, slightly broader than first segment. 

 Body brownish-black, cylindrical, granulate in appearance, anterior margin of pro- 

 thorax white; traces of white subdorsal, lateral, and spiracular lines. On abdominal 

 segments II, III and IV the tubercles are large, semiconical, and white, forming to 

 the casual glance an almost continuous white transverse band across segment; 

 on segment III the dorsal tubercles coalesce, forming a single conical black wart 

 arising from a white base; other tubercles small, whitish, with black setae. The 

 ventral surface is studded with white tubercles. Length 1.6 mm. 

 Stage II. 



Head and body deep brown, former small, slightly retractile, sprinkled with white 

 and with two creamy stripes on posterior portion. Body wrinkled in appearance.
