dotted, waved subdorsal band; sides very pale dotted tilled, pale spaced; 

 suprastigniatal band geminate, nearW black, dotted tilled; substigmatal 

 band white, :^hrunken by the fold, reddish tilled. Below it a gemi- 

 nate, sparsely dotted tilled reddish line, single subventral line and 

 the pale venter sparsely dotted. The larva gradually tapers pos- 

 teriorly, joint 13 being the smallest; slender, uniform. Tubercles a 

 little elevated, white, black marked, iv at the middle of the spiracle. 

 Central segments elongated; feet as before. 



Stage VI. — Head large, round and full, wider and higher than joint 

 2 yet the apex retracted in the expanded end of the prothorax; median 

 suture a little depressed, clypeus small. White, mouth a little luteous; 

 an erect black dash in clypeus; three l)road bands on each lolje from 

 the occiput converging to the clypeus, black edged, tilled with black 

 and brown dots; width over 3 mm. Body slender, cylindrical, elon- 

 gate; feet on joints 9, 10, and 13, with little rudiments on joints 7 and 8. 

 Broad gray black subdorsal and stigmatal bands, sharply edged, black 

 dotted tilled. Dorsal space brown, thickly dotted on an ashy ground; 

 a white speck at tubercle ii before, w^hile the blackish subdorsal 

 band is diluted with brown: lateral space pale ashen, tinely dotted in 

 dull red; a pale speck at tubercle iv; substigmatal band like the lateral 

 space; venter sparsely dotted in blackish,' illy detining a subventral 

 band, colored like the substigmatal one. Tubercles; dark gray, setti? 

 small, dark. Tubercle iv at the lower edge of the spiracle. 



Eggs from a moth tlying over the foothills at Platte Canyon. The 

 larvae fed on Er!o(j<»iHin. 



SYNEDA HASTINGSII Henry Edwards. 



Eggs. — Nearly spherical, a little iiattened on the base, very slightly 

 conoidal. Smooth, shining, dull yellow^ with a greenish olivaceous 

 tint. No reticulations or ribs, the surface covered with slight, shallow 

 depressions, their edges ill}^ detined; diameter 0.8 mm. 



Stage I. — Head rounded, oblique, luteous, diffusely brown streaked, 

 scarcely bilobed; clypeus high, ocelli small, black; width O.-l mm. 

 Body long and slender, motion semilooping, the LirMv thrashing about 

 violently before progressing. Slender, uniform, feet on joints 9, 10, 

 and 13, rather long and well developed. Whitish, green from the 

 food, a faint broad and clouded lateral vinous band. Tubercles ver}^ 

 small, black, obscure. Cervical shield brownish, not cornitied; feet, 

 except the anal ones, black. Later the lateral shade resolves itself into 

 three distinct lines — subdorsal, lateral, and suprastigmatal. There 

 is a white substigmatal band and faint brown line subveutrally; dorsal 

 space whitish. 



Stage //.—Head rounded, oblique, the apex under joint 2, full and 

 smooth, the sutures not depressed, clypeus small; whitish, three dotted 

 brown bands on each lobe and a faint linear streak dividing the clypeus
