66 THE CANADIAN ENTOMOLOGIST. 



the two narrow dorsal lines is paler, giving the appearance of a broad, 

 pale band with defined edges ; subdorsal line triplicate, narrow, faint ; 

 lateral line single, more distinct than the others ; subventral one not 

 broad, but distinct, yellowish with a green shade centrally. Spiracles 

 white. Venter pale green ; feet pale, all tinged with testaceous. 



Sixth stage. — Head rounded, shining black, the sutures of clypeus 

 and antennge white. A pale brown, mottled lateral band. Width, 2.7 

 mm. Body sooty black to the venter, which is pale whitish, tinged with 

 red, the subventral region less deeply black than the dorsal. On joint 2, 

 a distinct, narrow, white dorsal and subdorsal hne, the dorsal absent on 

 the rest of the body. A super-stigmatal, fine, white line, with a series of 

 five very narrow, faint lines above it bluish-white, and broken minutely 

 into dots. Above these two more lines, further apart than the five are 

 from each other, more distinct and continuous. The upper one of these 

 lines joins the subdorsal line on joint 2, but is much narrower than it is. 

 Spiracles white. Subventral line broad, its edges irregular ; pale yellow 

 with a central dull greenish or reddish shade. Subventral space mottled 

 with yellowish. Feet pale, greenish outwardly and tipped with reddisli. 

 Setfe present, short, dark. As the stage advances, the dorsal line appears, 

 resembling a shining black band against the sooty black ground colour. 

 Subventral space blackish, densely mottled with round, pale spots. 



At end of this stage the larvse enter ground. 



Pupa. — Of normal shape ; cremaster of two separate, rather distinct, 

 slender points, directed backward. Colour uniformly light brown.

 T<zniocampa pacifica, Harvey.

 head : — i.i mm., 1.5 mm., 2. [2] mm., 3.2 mm. 



Mature larva. — Head whitish-green with a few black piliferous dots. 

 Body enlarged at joint 12 ; feet normal in all the stages observed. Body
