of Coenocalpe magnoliata ; but I do not see any specific difference between these 

 two forms. Dr. Hulst placed them in separate genera, but he differentiates these 

 genera only in that Hydriomene has the thorax tufted posteriorly while Coe- 

 nocalpe is not so. Now several C. magnoliata from Maine, New York, and New 

 Jersey before me have fully as large thoracic tufts as Hulst's type of H. pernoiata, 

 and some of these specimens have been labeled C. magnoliata for me by Dr. Hulst. 

 Therefore I would transfer C. magnoliata to Hydriomene and place If. pertiotata 

 Hulst as a synonym of it. Henry Edwards is credited with a description of the 

 larva in Proc. Cal. acad. sci., feeding on Fuchsia Geranium, etc. 



Egg. Rounded elliptical, flattening marked but rounded, micropvlar end truncate, nar- 

 rower than the center, the other end depressed. Reticulations roundedly hexagonal, low, 

 rounded, distinct, becoming larger at the truncated end, finely granular shagreened all over; 

 cell areas distinctly hollowed; pale yellow. Size .8 X -6 X -4 mm. 



Stage I. Head rounded, full, clypeus high; pale luteous, faintly brownish spotted on 

 the tubercles, ocelli black. Body moderate, normal, pale whitish, unmarked. Tubercles 

 small, dusky; setae moderate, pale, glandular tipped. Segments irregularly wrinkled annu- 

 late; no shields; feet pale. 



Stage II. Head scarcely bilobed, erect, whitish with faint dusky spots on the sides of the 

 lobes, ocelli black ; width .6 mm. Body moderate, whitish, green from the food except at 

 the end, a narrow diffuse dusky green dorsal line; tracheal line white. Tubercles concol- 

 orous, obscure ; setae short, black. A barely indicated pale subdorsal line ; feet pale. 



Stage III. Head rounded, the apex in joint 2 green, freckled with purplish ; width 

 .85 mm. Body moderate, slender, smooth green ; subdorsal, lateral, and stigmatal lines 

 greenish white, hardly contrasted; dorsal vessel dark, marked on joints 11 and 12 with 

 purple brown. Feet pale; tubercles obsolete; setae short, dark. A little purple shading on 

 the foot of joint 10. 



Stage IV. Head rounded, bilobed, often held flat; green, finely brown freckled over 

 the vertex, mouth white ; width 1.5 mm. Body moderate, rather slender, segments wrinkled 

 posteriorly. Green, white shaded, dorsal vessel green ; subdorsal line white, not contrasted, 

 subventral fold whitish. Thoracic feet faintly brownish ; a purple band on the foot of joint 

 10 edged with white, a white line on the anal foot ; a dorsal purple band on joints 12 and 

 13. Tubercles small, round, white, elevated; setae short, black. Some of the larvae became 

 suffused with reddish dots bordering the pale lines or the subventral fold broadly pink 

 shaded. 



The larvae fed upon fire weed {Epi/obiiifn angustifo/inm), which seems to be 

 their natural food plant. Larvae from Kaslo, British Columbia.
