gellus, Clem. Some little collecting was done in the other orders, and 

 among the Hymenoptera the following have been kindly identified by Mr. 

 Wm. J. Fox : Urocerus flavicornis, Fab.; Urocerus albicornis, Fab.; 

 Ichneumon g7'aiidis,^ru\\.; Paniseus glaiicopteriis, Linn.; Vespa maculata, 

 Linn. ; Vespa germanica, Linn. ; Bombus bifarins, Cress.; Bombus 

 vagans, Sm. ? ; Pompilus tenebrosus, Cress.; Odyiierus leiicomelas, Sauss ; 

 and a species of Halictus not yet identified. Of the other orders the 

 greater part of our captures are as yet unidentified. Dr. Wm. Hughes 

 and Dr. Henry Skinner, my companions on this trip, rendered me much 

 valuable assistance in securing specimens. 



NOTES ON PSYCHODA. 



BY NATHAN BANKS, SEA CLIFF, N. Y. 



Mr. Alex. D. MacGillivray has sent me some Psychodidfe from 

 Ithaca, N.Y., for names. 

 Psychoda Siosso7ice, Will.  



One male (June). The wings are clothed with blackish hair, and 



with two broad irregular white bands. The fringe on the posterior margin 



is blackish (in siiperba whitish) ; the abdomen clothed with white hairs 



(in superb a with black); the legs are paler and with more white hair than 



in superb a; and the white hair on head and thorax is not as long nor as 



dense as in P. superba. A female (Aug.) which is larger and more thickly 



clothed with white hair is, perhaps, the same as Williston mentions, and 



is, I think, the female of this species. 

 Psychoda alb it arsis, n. sp. 



Wing moderately broad, tip not very acute, clothed with blackish 

 hair; some specimens show a patch of more dense hair on the middle near 

 the costal margin ; the fringe is black except at the tip, where it is white; 

 behind the fringe is over four times as long as the width of a cell; head, 

 thorax and abdomen densely clothed with black hair ; legs with dense 

 black hair, except the tarsi, which are white or pale yellowish. Antennae 

 very short, pale, with whitish hair. Length of wing, 2.4 mm. 



Differs from P. nigra by white apical fringe, and white tarsi and less 

 pointed wing ; from P. marginalis by larger size, white tarsi and black 

 haired body. Eight specimens, June and July, on Rubus odor at a at 

 Ithaca, N.Y. 

 Psychoda aiternata, Say. 



A few specimens of this species from Ithaca, N.Y., are smaller than 

 those from Long Island. |j 



Psychoda ci?ierea, Bks. ' 



One specimen from Ithaca of this species is not quite as dark as the 

 types.
