AMERICAN HTMENOPTERA. 41 



joints Bhort, together about as long as the two preceding, the whole quite 

 bristling with coarse hair; head polished, eyes widely separated, a deep irregu- 

 lar fissure back of each upper 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, truncate; claws of tarsi apparently bifid. Color shining 

 black; pro- and mesothorax 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; upper wings subviolaceous; first submarginal cell 

 rather ovate, longer than wide; lanceolate cell petiolate; under wings with 

 two marginal cells and one submarginal inner cell (all the other species have 

 one diecoidal 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; the submedial cell is without cross-nervure, but does not reach the 

 margin of wing, and the lanceolate cell is short. 



"%■ — Antennae (one specimen) ten-jointed, apical joint minute; lower half 

 of inner orbits white; anterior legs wholly whitish, also the middle tibim; 

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

 with no cross-nervure in submedial cell." 



Hah. — Farmington, Conn. Belongs to subgenus Monophadnus 

 Hartig. For mention of variation in neuration, also description 

 and habits of the larva of this species, see Trans. Am. Ent. Soc. 

 iv, p. 83. 



Selandria iufequidens Norton, Trans. Am. Ent. Soc. iv, 84.— "9.— 

 Length n.25 ; br. wings 0.50 inch.— Color piceous red, with the head, two stripes 

 on the side lobes of thorax, metathorax and breast black; abdomen piceous, 

 the apex of each segment darkest; a spot on each side of nasus and the labrum 

 pale; tegulse and edge of collar white; legs the color of body; wings smoky- 

 yellowish. Antennae black, fehort, formed as with halcyon, the apical joint not 

 decreasing suddenly in length ; face below the occiput quite depressed, rugose; 

 nasus with a shallow angular notch; claws deeply cleft; under wing with 

 one inner cell; outer cells open." 



Hab. — Texas. (Coll. Am. Ent. Soc.) Belongs to subgenus Mono- 

 phadnus Hartig. 



Selandria loiigipennis Norton, Trans. Am. Ent. Soc. iv, 84.— "J.— 

 Length 0.26; br. wings 0.68 inch. — Antennae, except two basal joints, wanting. 

 A suture like pit back of two upper ocelli, no suture at their sides, but strongly 

 channeled; three pits back of antennae; nasus rather wide, margin truncate; 

 labrum rounded; head and body shining, not highly polished; legs thickly 

 covered with white hairs; inner claw teeth long, just within the tip. Black, 

 palpi black; nasus, labrum, apex of all the femora, basal third of the tibiae 

 and the basal tarsal joint, clear white ; anterior claw joint waxen ; wings very 

 long, not very wide, upper pair blackish, semi-obscure, marginal vein bending 

 rapidly up to the costal margin, the whole vein forming almost a half circle; 

 lanceolate cell petiolate; lanceolate cell of under wing long, extending nearlv 

 to tip of wing, receiving the cross-nervure near its tip; traces of broken outer 

 nervures at ends of nerves; the neuration of the under wing is quite unlike 

 any other species of Section 1." 



Hah. — Near Cordova, Mexico.
