THE CANADIAN ENTOMOLOGIST. 189 



Stage III. — Very similar to preceding with an increase of secondary 

 black setce, single long white seta present as before; whitish dorsal lins 

 slightly enlarged in centre of each segment. Length 7 mm. 



Stage IV. — Head black, body purplish brown mottled strongly with 

 whitish ; pale dorsal line veiy distinct; subdorsal line almost lost in the 

 white marbling. Tubercles black, lateral ones distinctly orange at bases. 

 Long white setje of III and IV very prominent, especially on rear 

 segments. Tubercle V of anterior segments also bears a white seta which 

 is lacking in the posterior half ; other setae mostly black. Lateral abdom- 

 inal tubercles with several pale setce inclining to orange ; spiracle black. 

 Prothoracic plate split up into 4 chitinous mounds of which the two 

 anterior are the larger, bearing numerous setœ projecting over the head ; 

 the posterior carry 4 6 setœ. Legs black. Length 13 mm. 



Apaniesis phalerata Harris. 



The larval history of this moth has been already described by Gibson 

 (Can. Ent., XXXII, 369 ; id. XXXIV, 50). We venture to add, however, 

 some more precise details on the earliest stages, as it is probably in these 

 that we must look for points of distinction from closely allied species. 



k $ of the form radia?is Wlk., i. e., with W mark absent and broad 

 black border to red hind-wings, deposited ova freely in June ; these were 

 not dropped promiscuously as in the previous form but placed neatly in 

 rows in irregular groups on the underside of any r.vailable object. The 

 egg itself offers no points of distinction, being similar to those species 

 already described. We were unfortunately not able to breed the species 

 through. 



Stage I. — Head, lobes blackish; clypeus and mouth-parts as well as 

 suture between lobes, pale brown; body pale greenish red; tubercles dark; 

 on abdominal segments I minute, with white seta; II and III as usual. 

 Setae black on all segments except on 9th abdominal, where 9th dorsal 

 tubercle bears two long white and two black setse ; remaining tubercles 

 bear white hairs. Prothoracic plate the colour of body, except for a dark 

 mound on each side of the central line anteriorly; these mounds bear eacii 

 2 black setae. There is further a posterior row of four setœ, the outer 

 (lateral) one being white. Length 2.7 mm. 



Stage II. — Head as before. Body greenish brown with pale dorsal 

 stripes and orange tinges laterally at the base of the tubercles. Charac- 

 teristic of this stage is the great increase of setae on tubercle II which 

 bears 10-12 short black hairs. On abdominal segments III has 2 or ^
