americana in appearance and position, but lack the dorsal line of that 

 species. The cocoon is large, of a firm texture, dark brown. 



Iiyda ochreata Say. 



Solitary web-spinners on hazel {Corylus rostrata), many on the same 

 bush, each in a part of a leaf rolled over in a cornucopia-shape and 

 filled with gummy web. Rarely several in one leaf. 



^S^S^ shells. — Found singly on the back of the leaf, a thin, white, ellip- 

 tical skin, 1.5 mm. in size. 



Larva. — Head rounded, pale translucent testaceous, with a long pointed 

 antenna before and above the black eye; pouth brown. Width at ma- 

 turity 1. 4-1. 5 mm. 



A transverse, black, narrow cervical shield ; thoracic feet slender, pointed 

 colorless, unused; abdominal none. A pair of jointed, pointed, colorless 

 processes subventrally on joint 13; venter a little flattened; segments indis- 

 tinctly 4-annulate; color transparent shining greenish, no marks; alimen- 

 tary canal gives a blackish shade; dorsal vessel darker. 



Monophadnns rabi Harris. 



Sitting flat on the venter on ra.spberry leaves, singly; downy and green 

 like the leaf stems, which they closely resemble. Head rounded, mouth 

 pointed, green, pilose, eye black; width i mm.; segments obscurely 3- 

 annulate; on second and third annulets a series of Y-shaped setae, the 

 shaft strong and thick, the limbs pointed, three on each annulet above 

 the spiracle, those on the posterior annulet alternating with those before, 

 placed each a little below the one on the second annulet, the lowest one 

 just on the stigmatal line; two setae on the uppar part of the subventral 

 ridge (s.-v. ant.), and two on the lower part (s.-v. post.). The upper two 

 on second annulet and upper one on third, have black limbs; all the rest 

 white. Feet on joints 6-12 and 13. Body clear green, a little yellowish; 

 thoracic feet clear, with black tips. 



Last stage. — Smooth (no setae); all translucent green, scarcely shining ; 

 width of head i mm. Annulets with transverse watery areas and slight 

 irregularities to represent the setae; segmental incisures a little folded; no 

 marks. Enters the ground on acquiring this stage, and forms a frail co-
