THE CANADIAN ENTOMOLOGIST. 110 



Stage VI. — Length 15 mm. Head 1.6 mm. wide, as before, median 

 suture in some specimens pale. In general appearance the larvjxj in this 

 Stage are black, hairy caterpillars, either with a dorsal stripe (indistinct or 

 absent on posterior two segments of body) of bright yellow, expanded 

 almost into spots as in Stage iv., or a series of spots, one on each segment, 

 down the middle of the dorsum. In all specimens along the upper por- 

 tion of sides is also a series of paler yellowish spots. Tubercles as in last 

 Stage, the summits of iii., iv. and v. being pale brownish yellow. Bristles 

 from dorsal tubercles black. In most specimens those from iv. are black, 

 from v., vi., vii. and viii. pale, slightly rusty. Thoracic feet black, shiny ; 

 prolegs, upper two-thirds black, lower third pale greenish brown ; claspers 

 blackish gray. 



Stage F//.— Length 21 mm. In general appearance, black hairy 

 larvae, with a row of small yellow spots down the dorsum, and conspicuous 

 rows of yellowish subdorsal and lateral tubercles. Head 2.0 mm. wide, 

 subquadrate, flattened in front, slightly bilobed, shiny black ; ocelli black ; 

 epistoma dull whitish-brown ; cheek above ocelli near segment 2 pale 

 brownish ; antennse whitish-brown at base, remainder blackish. Body 

 cylindrical, segments rather deeply divided. Skin dull grayish black, 

 overlaid with patches and streaks of rich velvety black, particularly 

 dorsally and laterally, giving a deep black appearance. Dorsal 

 stripe broken up into a row of yellow spots. All the tubercles, 

 with but few exceptions, yellowish, with a black base, the subdorsal and 

 lateral series most conspicuous. Tubercle i. small, about one-ninth the 

 size of ii., which has a broad polished base. Spiracles black, with a dull 

 yellowish centre, close in front of tubercle iv. Bristles barbed, those on 

 dorsum mostly black, on lower portion of sides pale. Thoracic feet black, 

 shiny ; prolegs pale, each with a large black shiny plate anteriorly. 



The above larvae when they stopjjed feeding were put outside for the 

 winter. Unfortunately, however, none of them came through alive, so we 

 were unable to breed a series of the moths. Possibly some of us may 

 again be fortunate enough to obtain eggs, and rear the sjjecies to maturity. 



Distribution. — Calgary, Alta. (Willing) ; Beulah, Man., July 14 

 (Dennis) ; Awerae, Man., Aug. 6 (Criddle). 



6. Anna. — This species also seems to be rare in Canada. In 1S96 

 I collected six specimens of the variety persepJionc, and at that time asso- 

 ciated them with virguncula, probably because they occurred at the same 

 time, and I thought bore a somewhat close resemblance to that species.
