venter; legs pale yellowish, black on under side of first and second 

 joints of tarsus I; spines black, and spurs yellowish. Leg I with 

 very few spines, one at tip of femur, two or three on tibia, and 

 small ones at tips of tarsal joints. Wings pale, the apical and 

 posterior part brownish, with pale spots, larger pale spots beyond 

 the anastomosis, anastomosis dark brown, membrane clothed with 

 fine hairs. Costal area of fore wings rather broad, apical part 

 hardly as long as in A. disjunctus and A. costalis, but venation 

 about the same; the discal cell is hardly as long as the pedicel. 

 Lower median only slightly fractured at base of fork 5; in the hind 

 wings apical cells as in the fore wings. 



Expanse 26 mm. 



From Pinnacle Mt., Fulton Co., N. Y., 15th September 

 (Alexander). It has shorter legs than A. disjunctus or A. costalis. 



Anisogamus disjunctus, n. sp. (Fig. 22). 



Yellowish; darker on head between ocelli and antennae; mostly 



yellowish hair on head and prothorax, some black before base of 



wings; abdomen dark; wings nearly uniform pale yellowish, no 



markings, but a white hyaline spot on thyridium and also on 



arculus, membrane faintly roughened, clothed with sparse, fine, 



pale hair. Maxillary palpi with second and third joints in male 



subequal, each as long as space between eyes; in female palpi 



short, last joint not as long as basal joint of antennas, fourth about 



one half of fifth, third about three-fourths of fifth joint, second 



hardly as long as third. Mesothoracic strips quite long, rather 



broader behind; posterior warts of vertex transversely elliptical 



and rather small. Legs with black spines and pale spurs, 1, 3, 4. 



Fore wings moderately long, rounded at tip; radius strongly bent 



at base of stigma, discal cell a little longer than pedicel, fork 1 its 



width back on discal cell, fork 3 a little back of anastomosis, its 



base not very broad, but not acute, lower median much disjointed 



at base of fork 5, in hind wings the apical cells are similar to those 



of fore wings, but fork 3 is more acute at base. 



In both sexes the cheeks show a little blunt tubercle below. 



Expanse 26 mm.
