unicolor Lee. with pustulata, our most abundant species. 



marginalis Say, common. 



pubescens Fab., common. 



bihamata Mels., common. This species is exceedingly 

 active, jumping about in the net like a flea. M. discolor 

 resembles it superficially, but is not nearly so active. 



liturata Mels., common. 



fuscata Mels., common. 



suturella Helm., one specimen.' 



attenuata vSay, one specimen. 



discolor Mels., two specimens. 



Kmula Lee, one specimen (teste Horn). 



In addition to the fifty-three species enumerated above, 

 I have several Moydcllistoia which I think are new; one of 

 them is near the Californian vilis, Lee. I hesitate to describe 

 them, as there seems to be too man\- species now.
