2 ARKIV FÖR ZOOLOGI. BAND 13. N:0 7. 



Paltostoma Schiner — Neotropical. 



Curupira (Muller) Osten Säcken. — Neotropical (Brazil). 



Kelloggina Williston. — Neotropical (Brazil). 



Edwardsina, genus novum. — Neotropical (Chile). 



Cockerell has recently (1915) described the fossil genus 

 Paltostornopsis from the Gurnet Bay Oligocene of England. 

 Edwardsina, gen. n. 



Antennae witli 15 segments, the second scapal segment 

 shorter than the first; last flagellar segment longer than the 

 penultimate, elongate-conical. Rostrum moderately elongated, 

 a little longer than the vertical diameter of the head. Palpi 

 inserted at the base of the rostrum, long and slender, 4:-seg- 

 mented, the first segment longest, the third shortest, the 

 second and fourth subequal; palpi extending slightly beyond 

 the tip of the rostrum. The mandibles project beyond the 

 other elements of the mouthparts, their outer edge with a 

 comb of slender teeth. Eyes dichoptic (at least in the female), 

 rather small, hairy, the front wide; eyes not divided into 

 tvvo parts by an unfacetted band. Head broad, gense very 

 prominent. 



Legs slender, the före tibiae with a single spur, the middle 

 and posterior tibise with two spurs; fifth tarsal segment with 

 a patch of long, chitinized spines; claws with about five 

 teeth that decrease in size toward the base. Wings large 

 and ampfe with a very generallized venation, as follows: 

 Se is lacking; Ri very long; Rs short, träns verse, near its 

 tip bent at a right angle and here sending a long spur back 

 to about half the distance to the arculus; R2+3 very short 

 to almost lacking; veins i?^ and i?3 distinct, running generally 

 parallel to one another, but cell R2 being broadest at mid- 

 length, vein R^ ending rather close to i?/ at the wing-margin; 

 basal deflection of R4+5 almost in alignment with the base of 

 the sector; vein R4+5 running generally parallel to R3 but 

 diverging from it near its end; r — m distinct, long, but con- 

 siderably shorter than the basal deflection of J/3; M2+2 long, 

 at about twothirds its length with a strong upward deflec- 

 tion to indicate the course of vein M2, vein 3I2 being atro- 

 phied and represented only by a slight spur; fusion of M3 

 and Cui extensive, the outer deflection of M3 present; fork 

 of Cti rather acute, the veins gradually diverging; a single 

 anal vein (the second) attains the wing-margin but the re-
