THE CANADIAN ENTOMOLOGIST. 5 



Length 0-85 in. ; bead larger in proportion to body tban before, not so 

 strongly bilobed, rather flattened in front, deep black, with a few short hairs; 

 palpi dull reddish tipped with black. 



Body above distinctly annulated, of a deep velvety black color, with tubercles 

 as before, hairs much longer, chiefly black, those on hinder segments longer 

 than the others, with a few whitish ones mixed with them. Along each side 

 of body, close to under surface, is a row of tufts of reddish-orange hair. 



Under surface dark brown, with a row of tubercles on 5th, 6th, 11th and 

 12th segments, with short tufts of reddish-orange hair ; feet black, with pale 

 streaks ; prolegs reddish orange. 



From the 20th May to the middle of June the larva made very little growth? 

 and about the latter date began to contract previous to entering the pupa 

 state. On the 20th of June I observed that it was spinning a light web, and 

 about to undergo its change when another description was taken : 



Length 080 in. ; head medium size, black and shining. 

 Body above pale brown, with dull black tubercles and spreading tufts of 

 black hairs; a dorsal stripe pale, dull, whitish pink. 



Under surface dirty brownish white ; hairs on tubercles on 5th, 6th, 11th 

 and 12th segments short, blackish ; feet blackish brown ; prolegs pale brown 

 and hairy. 



On the 22nd of June it changed to a dark brown chrysalis, producing the 

 imago July 6th, which proved to be a female. 



Arctia Bimaculata, n. sp. — Expands one inch : palpi reddish ; head, 

 antennae and thorax reddish brown; Abdomen stout, dull red with a faint 

 broken dorsal line ; body below, brownish red ; feet of a little darker shade. 



Primaries above dull reddish brown, with a round white sjyot within the 

 middle and just below the median vein. 



Secondaries dull red, with a black spot about the middle, and a ivide, irregu- 

 lar band alowj the hind margin, extending from the anal angle to near the 

 tip, where there is a small black dot. The hinder part of this band lies close 

 to the hind margin ; beyond, it is slightly advanced, having a streak of red 

 between it and the edge ; margin edged with a blackish line, fringe reddish. 



Under surface of both wings red, of a little brighter shade than secondaries 

 above. 



Primaries have a blackish irregular bar across the end of the discal cell 

 and extending a little way above it, nearer the tip is a brown dot. The 

 white spot above is scarcely produced below, being red, a little fainter than 

 general color. 



Secondaries have the same markings as above, the central spot is a little larger 

 and the marginal band narrower, not extending to the hinder edge of wing.
