Corythucha obliqua Osl^orn and Drake. 



The authors described this species from a single specimen 

 that was taken in California by Mr. Dury. Our collections 

 now include specimens from Oregon and Idaho, besides the type 

 locality. 



Corythucha immaculata Osborn and Drake. 



The food plant of this species has not been recorded. We

Corythucha distincta Osborn and Drake (Fig. 1, variety). 



This is a very common lace-bug throughout the western part 

 of the United States. Our collections include specimens from 

 Washington, Montana, Wyoming, Utah and Colorado. Mr. 

 McAfee states that he has specimens from California. In 

 western collections we have seen this species labeled " Corythucha 

 contami7iata Uhler MS." Our long series of specimens indicate 

 the type to be the typical form of the species. The Utah 

 specimens were taken on Carduus lanceolatus by Larson.

This new variety is armed on the outer margins of the 

 elytra, except distal third, and lateral margins of the pronotum 

 with short spines. The color is a little darker than the typical 

 form. All specimens of this variety were collected at Florence, 

 Montana, June 1, 1912, by Mr. Parker. One specimen bears 

 the food plant label "thistle."
