Mr, R. W. Dawson has had the good fortune to collect a male in 

 copulation with a female, the latter proving to be hippodamia Fox. 

 I have examined the type specimens of both oceola Blake and hif- 

 poramia. This species is much more widely distributed than our 

 previous knowledge has indicated. Its geographical range as 

 known at present, presents some peculiarities not exhibited by other 

 species of Pseudomethoca; thus from east to west it includes the 

 States of South Carolina, Florida, Georgia, Alabama, Mississippi, 

 Louisiana, Texas, and Arizona, and an extension northward into the 

 States of Colorado, Kansas, Nebraska, and South Dakota.

Type. — Male, Texas, in collection of American Entomological 

 Society of Philadelphia. 



I have examined the type specimen and find that the genitalia 

 are of the same general type as in oceola Blake. Time was not avail- 

 able for making a drawing of the genitalia. The species may be 

 recognized by the characters given in the key.
