THE CANADIAN ENTOMOLOGIST, 



I 



segmental stigmatal red dots and a similar row of larger substigmatal yellow 

 dots. Claspers of abdominal feet pale. In some examples the substig- 

 matal yellow dashes almost form a continuous band, and there are 

 indications of a geminate yellowish dorsal line ; but this latter rnarking 

 almost disappears under a lens. 



CArjysa/is.— B.ea.d large, eyes prominent, thorax very slightly ridged 

 along the dorsal line with an elevated point posteriorly centrally and a 

 pair of smaller subdorsal points, two points on the lateral edge of wing 

 cases and one near the middle of outer margin of wing. Abdomen 

 rounded dorsally, nearly straight ventrally, with a subdorsal row of conical 

 points ; cremaster broad and flat, colour sordid white with an obscure 

 golden tint, dotted with black and shaded with smoky gray, broadly so 

 dorsally (except a narrow dorsal line), narrowly stigmatally, broadly 

 ventrally, and more irregularly and clouded over the thorax and cases. 

 All the points tinged with shining gold or bronze. Length 13 mm.; width 

 6 mm. 



Food-plants. — Lupine (Lupinus) zxidL'0!x\%'Ci& (Carduus). 

 CalUdryas etibide, Linn. 



Egg. — Spindle shaped, truncated on basal end, distinctly vertically 

 ribbed and faintly transversely striated. Colour pale white, becoming ochre 

 yellow before hatching. Length i mm.; diameter .3 mm. 



First larval stage. — Head round, smooth, ochre yellow, the ocelli 

 dark brown ; width .3 mm. Body smooth, concolorous with head, with 

 a number of long tapering setae, curving forward, about six on each 

 joint. 



Second stage. — Head rounded, subtranslucent yellowish ; width .5 mm. 

 Body cylindrical, pale yellow, with many short hairs arising from granu- 

 lations of considerable size. Some of these hairs overhang the head and 

 many terminate in a little knob. Under the microscope the setae are 

 seen to be ail glandular, transparent and swollen at tip, and arise from 

 large conical tubercles, between which the body is very minutely punctured. 



Third stage. — Head pale green, mouth parts yellowish, many short 

 pale setae ; width .8 mm. Body annulated, about six annulets per segment. 

 Colour yellowish green, not shiny, v/ith a distinct rather broad, pale green 

 stigmatal line. The fleshy tubercles on the body are slight, the setae 

 very short but slightly blackish and bear at tip large, round, clear Uquid 

 drops.
