 BY T. D. A. COCKERELL, UNIVERSITY OF COLORADO, l'.OULDER, COLO. 



Palaochrysa concinnula, sp. nov. (Fig. 5.) 

 Length of anterior wing ab< lit 12 mm ; venation dark brown. 



Anterior wing: Costal cells about 14; cells between radius and 

 radial sector 9, the first fully twice as long as the third J cells between 

 radial sector and media 10, successively shorter from the fourth on, but 

 without any abrupt change of size, as in Tribochrysa ; "third cubital cell" 

 (M 8+ i) divided longitudinally, as shown in the figure; cells beyond "third 

 cubital" 9, but the cell counted as the tenth of the series above may as 

 well belong to this series, reversing the numbers cited ; six veins forked 

 on the lower margin, but the fork of the fifth very small. 



Posterior wing: 'Third cubital" not divided; other characters are 

 shown in the figure. (In all the figures A and R are the "third cubital.")
