 Fort Lupton, Colorado. 



The writer found the species hreedino" on Lepidium tliin'beri 

 which was growing around the adobe ruins of old Fort Gra- 

 ham, near Bonita, Arizona. A short distance away was found 

 an extensive growth of the same plant as determined by the 

 botanists on the expedition, which was abundantly infested by 

 Lygns elisiis V. D., but no specimens of Lopidea Icpidii were 

 to be found. It would seem from this that the species breeds 

 only in favored spots. 



The writer has seen specimens of both media and lepidii 

 from Colorado where the species appear to overlap. In the 

 eastern States there is only one species that could be taken for 

 media Say, it having the inner hook on the rigiit clasper very 

 long and more slender than in lepidii, the same clasper having 

 also near the tip a distinct dorsal projection with five or six 

 serrate teeth at the top. 



Lopidea minima new species (Plate X, Fig. 7). 



Very small, reddish with fuscous and black, resembling 

 media in coloration ; genital claspers distinctive of the species. 



$. Length 3.8 mm., width 1.4 mm. Black, the basal half of the 

 pronotum orange to red ; hemelytra red, bordering the commissure, 

 membrane and scntellum, fuscous.

The writer took the species on Coiirsetia microphylla which 

 is probably the food plant. At that date the species was not in 

 season, the two specimens taken probably being stragglers of 



the brood.
