^FFEISTDIX j^. 



Some of the following notes and additions were kindly sent nie by Dr. Dyar as this memoir 

 wr.s being printed. They fill np gaps in our knowledge of the life histories of the species. 



EGG AXD STAGE II OF ICUTHYUBA ALBOSIGMA (see p. 1.50). 



E(i<j. — Laid two to seven together on the upper side of the leaf. Hemispherieal, the base flat. 

 Diameter, O.'J mm. Shells dead white. Larva hatches by a hole in the top. 



IStuge II. — Uead black, mouth a little paler. Width, 8 mm. Body yellow, purple-brown on 

 the sides, except the large yellow subventral warts on segments 2-4, G, 9-12; the color extends 

 across tlie back on segments 2, ."i, 7, 8, 12, and lo posteriorly, not completely replacing the yellow 

 on segments 7 and 8. An indistinct triplicate dorsal line, puri>le-brown; venter dull brownish. 

 Segments 5 and 12 a little enlarged dorsally. Hairs white, few. Cervical shield nearly linear, 

 black. Length of larva, 8 mm. (Dyar.) 



EGG AND LARVAL STAGES OF NADATA GIBBOSA (see p. 1-13). 



Ef/fi. — (Jefl'erson, N. H.) Three laid together near edge on underside of leaf Spheroidal; 

 base tiat, opaque white; diameter, 1.1 mm., 0.7 mm. high. Ivcticulatioii linear but rather high 

 and with harder base, rather snuill and regulaily hexagonal; the pores at the angles distinct, 

 bead-like in the empty shell. The cells between I'cticulations form shallow hollows as in hchrcii.sii. 

 (Dyar.) 



Lurrul stiifics. — A larva bred at Jefferson, N. 11., had live stages, with width of head as follows: 

 J, about 0.7 nun.; II, 1.2 mm.; Ill, 2 mm.; IV, about 3 nun.; Y, -1.0 mm., thus api)areutly omitting 

 the normal stage III instead of II, as the Yosemite ones did. (Dyar.) 



EGG AND LARVAL STAGES OF NEKICE BIDENTATA (see p. 171). 



Egg. — Rather more than hemispherical, with a flat base; not shining; whitish yellow. 

 Diameter, 1 mm.; height, 0.7 nun. Ifeticulations small, linear, rather elongate, irregularly hex- 

 agonal; nuxch smaller toward the micropyle, where there is an almost smooth area surrounding a 

 slight i)rominence, or all smooth. (Dyar.) 



iStxge I. — On hatching the larva runs to the tip of a tooth on the side of a leaf or end of the 

 midrib and sits with the anterior part of its body projecting beyond the edge. It eats the upper 

 portion of the leaf, leaving the lower epidermis. Head shining, blackish, notcln^l a little at the 

 vertex, paler below, nu)uth vinous; width, 0.5 mm. Lody whitish with a green tint, feet and 

 tubercles black ; cervical shield blackish. A dorsal spot on segments and 12, and subventral ones 

 on segments 4, 0, and 10, brownish red. Later a slight prominence appears dorsally on segments 

 G and 12 corresponding to the tubercles i of each side and being the lirst indication of the future 

 high humps. Seta- normal, i-v, vi absent, three on the distiiu-t leg i)late. 



Stage II. — Eating tlu; whole leaf and resting on a perch formed of the midrib from which the 

 substance of the loaf has been eaten away by the larva. Head higher than i)rothorax, slightly 

 bilobed, shining luteous with brown side stripe to vertex; width, 0.8 mm. Body cylindrical, shin- 

 ing green, a little dorsal red-brown dot on segment 5; a considerable bilobed process on segment 0, 

 the anterior lobe longest, red-brown; a single low, broad hump, on scgnuMit 12, yellowish on the 

 sides bearing tubendes i toward apex. Legs all red brown with subventral spots, more reddish 

 on segments 2 to 5 and 11, all used by the larva. Setie short and dark, normal, i-vi, with vii and 

 viii, on tlu; legless segments as usual. On segineiit (i, tubercle i is borne on the base of the horn. 



Slagr HI. — Head llattened in front, depressed at vertex; yellowish green, a l)lack line from 



vertex of each lobe to side of mouth; width, 1.3 mm. Dorsal processes visil)le on segments 5, (!, 



7, and 12, highest on G, but all slight, brown tipped. None on the other segments. Faint, oblicpie, 



lateral, yellowish lines. Legs red-browu, with a faint yellowish substigmatal shading. Body not.
