114 STUDIES IN AMERICAN EPHYDRIDAE (dIPTERA) 



lateral ciliation normal confined to basal third and rather clustered, not seri- 

 ally arranged. Second vein of wings straight; second costal section three 

 times length of third; no appendages present. Length. — 3.0 to 4.0 mm. 



Female. — Similar, but lateral series on fore femora of six to ten bristles well 

 separated and rather stout, sometimes the series is interrupted at apical third. 



Tijpe.—d" ; Austin, Texas, Oct. 1900, [University of Wash- 

 ington]. Paratypes. — In the original citation of the typical 

 series for this species a male of appendiculata was unintentionally 

 included. Of the five females, four of these are in very poor, 

 stained condition and practically of no value. However, I have 

 a series before me of six males and three females, including the 

 holotype and allotype, in good condition which may be considered 

 typical.

In this we have the commonest species of the genus inhaliiting 

 the Nearctic region, and it is found all over the United States 

 east of the Rocky Mountains. Although a few other species 

 have been generahy confused with it, fortunately it is involved 

 in little or no synonymy. It has, however, some variations which 

 are confusing and are lia])le to be considered distinct forms by 

 those not having an extensive series for study. 



This species, as I consider it, has the face and parafacials bi'oad, 

 of a silky lustre when in good condition. In rare cases the face 

 is narrow and dull lead color. Generally the face is yellowish 

 gray with stains of yellow or brown, sometimes largely brown or 

 on the other hand silvery gray to almost white. The parafacials
