8 KANSAS UNIVF.RSITV QUARTERLY. 



The middle femora also have cilia, shorter and moi-„ delicste, 

 throughout their length. The hind tibiae are red only on the b?isal 

 third. 



A female from Florida (Johnson) has black femora, tegular and 

 orbital cilia, and antenn;^;. The pleura; and sides of abdomen .^ire 

 noticeably silvery dusted, and the face also is silvery. It evidenitly 

 represents a new species of the foregoing group, but it would '\be 

 difficult to prepare from- a female a description from which the m^iV 

 could be recognized. 



Dolichopus calcaratus, n. sp. 



Differs from grains Lw. in the following respects: hind tibiae 

 wholly black; veins of wing black instead of yellow; fore coxae even 

 more densely hairy and bristly. 



One male, Dover, N. J., June i8 (C. W. Johnson). An examina- 

 tion of more material may yet show that in this case these characters 

 are not of specific value. 



Dolichopus detersus Loow. 



Two males and one female, St. Anthony Park, Minn. (Lugger); one 

 female, Brookings, S. D., June 19. 



Loew's brief Latin description may be supplemented as follows : 

 Third joint of antennas rounded, rather small; thorax rather high and 

 prominent in front; hypopygium black, lamellae small, oval, dirty 

 whitish, part of the hairs yellow ; anterior tarsi slightly longer than 

 the tibiae. 



Female. Face wide, thinly dusted above, thickly below, silvery; 

 hind femora not ciliated, hind tibiae and the costa not thickened.

 length of the tibia, middle tarsi about \]/^ times. Hind tibiae incras- 

 sated; hind femora below with delicate blackish cilia of moderate 

 length. Wings almost hyaline; costa slightly thickened; last segment
