42 CYRTIDAE OF NORTH AMERICA 



I believe that Nothra ameiicayia is the same as the form known 

 as P. misella. I have seen males of misella, 7.5 mm. in length, 

 and two -specimens with a yellowish scutelliim. The males of 

 this species arc almost impossible to separate from P.flavipes, and 

 I would have been inclined to make it a synonym of that species, 

 had I not recently seen two females. These females have a black 

 scutcUum and the prcsciitellar callosities are black. The species 

 is distinctly smaller than the average specimens of P. flavipes. 

 One of the above females was collected at Forest Grove, Oregon 

 (M. C. Lane), the other near Corvallis, Oregon (A. L. Lovett). 



Pterodontia johnsoni new species (PI. VI, fig. 21.) 



Hody wlioll}' blackish, semi-shining. Eyes contiguous and pilose; the pile 

 on the eyes of the type specimen shorter than on P. flavipes. Head black. 

 Antennae brown with the usual terminal setae. Hmneral and praealar cal- 

 losities black. Thorax with black pile. Squamae brownish hyaline, not so 

 pointed as in P. flaripcs and with black borders; the surface with black pile. 



The sides of the last three abdominal segments have a brownish tinge which 

 extends almost to the middle of the segment, ^'entor mostly blackish, with 

 some reddish brown color. Femora black with a slight browi\ish tinge; tibiae 

 dark brown, the tarsi paler. Tips of the claws black. All the tibiae with two 

 spui"s, the inner one verj' short but the outer one quite conspicuous. Knees 

 brownish yellow. The wing venation is verj^ near that of P. flavipes, but, in the 

 tj-jie specimen at least, there is a suggestion of the outer discal cros.s-vein, al- 

 though there is no upper veinlet from the discal cell. Thus the wing is inter- 

 mediate between the type of P. analis and flnripes. There is a brownish color 

 in the costal cells, the rest of the wing being whitish hyaline. Length, 5.5 mm. 



Habitat. — Seattle, Washington. 



Type. In' the collection of C. W. Johnson, from whom I re- 

 ceived the specimen. The type is slightly mutilated. Two legs 

 and a part of one wing, which had been broken oft", mounted on a 

 separate card point. 



There are two iiaratyi)os in the collection of Prof. J. AL 

 Aldrich, taken at Boise, Idaho. They are a little lighter in color 

 than the type. The vein closing the discal cell is not so angu- 

 lated. Ocellar tubercle higher than in Jlaripes. Femora dark 

 brown. Prof. A. L. Alelander loaned a specimen collected at 

 Coupeville, Washington, July 20, 1898, which is practically the 

 same as the Idaho specimens.
