148 NATHAN BANKS. 



I have specimens from Hyattsville, Md. ; Sherbrooke, Canada; 

 A.gric. College, Mich. ; Bright Angel, Colorado Canon, Arizona, 

 July 12th ; and Las Vegas, Hot Springs, New Mexico, August 11th ; 

 Ft. Collins, Colo. ; Ashland, Oreg. ; Sandusky, Ohio. It has also 

 been recorded from Axton, New York; Peuna., Nova Scotia, New- 

 foundland and Canada. According to this distribution it would 

 seem to be a northern form. It is distinguished from Ch. oculata 

 by the green gradate and other veinlets. Fitch's Ch. xanthocephala 

 and Ch. bipunctata belong to this species, and also, I believe, Ch. 

 bransmarina Hag., and Ch. latipennis Schn. All the specimens I 

 have seen were taken in July and August. 



Chrysopa ypsilon Fitch.— This species is extremely similar to Chrysopa 

 chi, ami can best he described in comparison. The head is marked as is that spe- 

 cies, except that the median black mark forms a Y instead of an X ; the black 

 below antennal sockets is not connected above between antennae. The Y is some- 

 times connected to the snbmedian pair of black dots on the vertex. The thorax 

 is marked as in Ch. chi, as are also the wings, but the cross-veins are more heavily 

 marked with black than in that species. The wings have the same form. Length 

 ] 1-15 mm. 



I have specimens from Ithaca, Axton, Adiron. Mts. (June) and 

 Sea Cliff, X. Y. ; the latter were taken in May. I have also seen 

 specimens from New Jersey and Sherbrooke, Canada. It is very 

 close to Gh. chi, but the difference in head-markings appears to be 

 constant, Hagen records a specimen from Washington, D. C, but 

 I have not met with it here. 



Chrysopa chi Fitch. — Head 'green ; a black spot under each eye, not con- 

 nected to eye, a similar black spot each side on clypeus, lower margin of anten- 

 na! sockets black, but not the outer margin, the black continued upward between 

 antenna' and divided in a Y, often connected to the submedian dots of vertex, 

 the entire mark forming an X, a black dot on vertex each side near eye ; all the 

 marks are shining black. Second joint of antennae black ; last joints of palpi 

 black ; pronotum green, with three black spots each side; rest of thorax, the ab- 

 domen, and legs green, each anterior lobe of the mesothorax has two black dots. 

 Wings hyaline, veius green, gradate veinlets and some cross-vein lets near base 

 black, many of the other cross- veinlets black at one or both ends, pterostigma 

 not very distinct; hind wings with the costal veinlets wholly black. Wings 

 lather broad, broadly rounded at tips. Length 14 mm. 



Described by Fitch from New York. 



I have specimens from Franconia, New Hampshire (Mrs. Slosson), 

 and Axton, Adiron. Mts., N. Y., June. Several of the specimens 

 have clinging to the wings one to three specimens of a little Cecido-
