AMERICAN HYMENOPTERA. 83 



cond submarginal cross- nervure receiving the recurrent nervureat the intersec- 

 tion of second and third cells, lanceolate cell petiolate, under wing with no inner 

 cells, its marginal cell with a small appendiculate cell at the tip. 



Cordova, Mexico. (Prof. Sumichrast.) One specimen.

9-— Length 0.25; br. wings 0.40 inch. — Antennae moderately enlarged in 

 middle, first and second joints of equal length, four apical joints short, together 

 about as long as the two preceding, the whole quite bristling with coarse hair ; 

 head polished, eyes widely separated, a deep irregular fissure back of each up- 

 per ocellus, no channels at sides of ocelli, three smooth basins back of base of 

 antennae, having in the centre of each a minute deep pit; nasus wide, trun- 

 cate ; claws of tarsi apparently bifid. Color shining black; pro- and meso- 

 thorax and scutellum rufous, apex of the latter black ; nasus and legs white, the 

 tarsi blackish ; base of coxae and a line down the upper side of legs black ; up- 

 per wings subviolaceous; first submarginal cell rather ovate, longer than wide ; 

 lanceolate cell petiolate ; under wings with two marginal cells and one sub- 

 marginal inner cell (all the other species have one discoidal inner cell and no 

 submarginal), all the outer cells closed as in figure 3 (Trans. Am. Ent. Soc. i, p. 

 151), the bounding nervure not touching the margin; tbe submedial cell is 

 without cross-nervure, but does not reach the margin of wing, and the lanceo- 

 late cell is short. 



%. — Antenna? (one specimen) 10-jointed, apical joint minute; lower half of 

 inner orbits white; anterior legs wholly whitish, also the middle tibiae; under 

 wings with one marginal and no inner cell, formed as in figure 2 (ibid.) with 

 no cross-nervure in submedial cell. 



Farmington, Conn. The wings present a good many supplementary 

 nervures and irregular cells. The first marginal of one wing has two 

 additional cross-nervures ; on another wing are two additional discoidal 

 cells. One under wing outer cell has three outer nervures, bent and 

 overlying each other. 



The larvaa feed on the Hickory (Juglans squamosa). They are 

 found upon the under side of the leaf, sometimes fifteen or twenty on 

 a leaf, which they eat from the outer extremity inward, often leaving 

 nothing but the strong midribs. They cover themselves wholly with 

 white flocculent tufts, which rub off when touched, leaving a green, 

 twenty-two legged worm about 0.75 inch when full grown, darkest * 

 above and with indistinct blackish spots on the sides. The head is 

 white with a small black dot on each side. Specimens taken with 

 the leaves July 4th, went into the ground about July 20th. The co- 

 coon is formed near the surface of the ground and covered with earth 

 and sand drawn together. Four specimens came forth about August 

 22nd, all seeming very small for so large larvae. 



Dr. Packard (Guide p. 223) mentions a similar larva feeding upon 

 the butternut, which may prove to be the same with this.
