8 KANSAS INIVERSITV QUARTF.RI.V. 



The middle femora also have cilia, shorter and more delicate, 

 throughout their length. The hind tibiae are red only on the basal 

 third. 



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

 orbital cilia, and antenn;t. The pleurse and sides of abdomen are 

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

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

 difficult to prepare from a female a description from which the male 

 could 1)6 recognized. 



Dolichopus calcaratus, n sp. 



Differs from grati/s I,w. 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 iS (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 Lomv. 



Two males and one female. St. .\nthony Park. Minn. (Lugger); one 

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

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

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

 length of the tibia, middle tarsi about \% times. Hind tibiae incras- 

 sated; hind femora below with delicate blackish cilia of moderate
