76 HAUSTELLATA. — LEPIDOPTERA. 



Sp. 2. UrtiCfE? AUs ulhidis, ant'icis fer?. immaculatis, posticis punctis iribus 



nigricantibus. (Exp. alar. 1 unc. 7 lin.) 

 Bo. Urticfe. ZT/ii/irr'j^— Sp. Urticae.? Steph. Catal. No. 6027. 



Antennae white, with dusky radii : head, thorax, and apex of the abdomen the 

 same, middle of the latter slightly fulvescent, with a dorsal and two lateral 

 streaks of black dots : anterior wings whitish, with a single minute black dot 

 on the disc : posterior the same, with two dusky spots parallel with the hinder 

 margin, and one larger and paler in the centre : legs white, the anterior, with 

 the femora, fulvescent within, and the tibiae with a narrow black streak : tarsi 

 of all white. 



This insect closely resembles the foregoing, if it be not a variety thereof: its chief 

 distinction consists in the antennae being white, the abdomen very slightly 

 fulvescent, and in the greater purity of the white colour of the wings : it is the 

 Bo. Urticte of the Ent. Trans. ; but whether the Bo. Urticae of Hiibner is re- 

 ferrible to this or to Sp. papyratia, which is of totally dissimilar form to the 

 present, although somewhat similar in the colour of its antenna;, &c. I am 

 unable to determine. 



Of this species I have seen two specimens only a female, in the 

 collection of Mr. Haworth, and a male in my own : the latter was 

 taken on Epping-forest, many years since ; Mr. Haworth's specimen 

 in Yorkshire. 



Sp. 3. Papyratia. Aiis albis, anticis punctis dixcoidalibus Uneoltique punctorum 

 nigrorum ad apicem nigris, posticis swpissiinc immaculatis. (Exp. alar. 1 unc. 

 6—8 hn.) 



Ph. Papyratia. Marsham, Linn. Trans, i. pi i. /. 4.. — Sp. Papyratia. Steph. 

 Catal. No. 6028. 



Antennae white, with black rathi : head, thorax, and tip of the abdomen clear 

 white, middle of the latter bright orange, with the usual dorsal and lateral lines 

 of spots: anterior wings white, with tuo or four black spots on the disc, and 

 an oblique streak of black dots (varying in number, and sometimes obsolete) 

 at the disc : posterior wings generally immaculate white, sometimes with a 

 dusky speck in the centre, and one or two obsolete ones near the margin. 



Wings sometimes totally immaculate. 



Caterpillar deep brown, with a few black spots : it feeds on various aquatic plants, 

 especially the water-mint, white ladies bed-straw, &c. and is found in the 

 autumn : the pupa is dusky, and changes about the middle of June to the 

 imago. 



Not common ; but taken occasionally in the larva state in the 

 marshy places near London; especially near the banks of the Croy- 

 don Canal, in the Isle of Dogs, Plaistow, and Hackney-marshes, &c.
