ocellus, the shape and the venation of the wing, the armed hind 

 legs, the long labium, and the swollen gense all point to a close 

 affinity with the subfamily Carsidarinae and, especially, with the 

 genus Carsidara. 



Carsidaroida heterocephala sp. nov. Plate I, fig. 7. 



Length of body, 2.6 millimeters; length of forewing, 4.8; 

 width, 1.7 ; width of head, 0.8. General color brownish ; thorax 

 with alternating orange and brown or blackish stripes; head 

 light brown or with a yellowish tinge; eyes black; abdomen 

 darker than thorax. Body large. 



Head not as broad as thorax, scarcely deflexed; vertex rela- 

 tively small, more than half as long as broad, with a conspicu- 

 ously raised margin extending between vertex and each eye 

 and along posterior margin, but the posterior ocelli outside of 

 this elevated rim; within the rim the vertex is rather flat, pre- 

 senting the appearance of a saucer with perpendicular sides; 

 front ocellus situated a little anterior of the center of this saucer, 

 at obscure junction point of vertex and gense. Genae produced 

 in front into a pair of very large, diverging, antennal sockets 

 to the ends of which the antennse attach, without genal cones 

 except two exceedingly small ones far back under head just in 

 front of labrum; antennal-socket enlargements of gense very 

 large and prominent beneath head, extending back toward labrum 

 as a pair of parallel half-cylinders. Antennse not quite as long 

 as body without wings, nearly four times as long as width of 

 head with eyes, slender, black at tip. Eyes relatively large. 

 Labium very long. 



Thorax large, not strongly arched; pronotum with a small 

 epiphysis in front at center; legs long, rather large; hind tibiae 

 with a large spur at base and five large black spines at apex, 

 one larger than the other four; other tibise with a fine comb of 

 slender spines at apex. Forewings long, about three times as 

 long as broad, hyaline with a faint smoky tinge, with several 

 brown or black spots scattered about in apical portion; ptero- 

 stigma rather large; with a callus (pseudovein) connecting radius 

 and media and another connecting the radius and pterostigmal 

 vein. 



Abdomen very long and slender, tapering gradually to genital 

 segment. Male genital segment rather small; anal valve with 

 a broad, apically rounded erect portion and a horizontal prolonga- 

 tion, triangular in shape, reaching backward ; forceps as long as 

 anal valve, curved inward and forward, broadly rounded at apex ; 

 with a second and smaller pair of forceps cephalad of principal
