agrees with them in having the fourth tarsal joint simple. It is quite probable that 

 these species should be separated generically from P. buqueti, as de Bonvouloir asserts 

 in his table and text that the fourth tarsal joint is excavate-emarginate, having probably 

 used the latter species as his type. In this case Euryptychus will be valid.

This is one of the few genera at present admitted to the family which help to make 

 its definition difficult. From all those occurring in our faunal limits it will be known 

 by the very abruptly narrowed posterior coxal plates.

Two forms have been separated by Leconte and admitted by de Bonvouloir, — 

 A. druryi being more opaque and A. latreillei more shining. The former is charac- 

 teristic of the more southern portions of the United States, while the latter is peculiar 

 to the western regions, especially those bordering the Pacific. The two forms occur 

 within our fauna and closely intergrade. 



ENTOMOPHTHALMUS. 



Entomophthalmus, de Bonvouloir, Mon. des Eucnemides, p. 513 (1870). 



The species of this genus have a facies separating them at a glance from Micro 

 rhagus. The very small second and third joints of the antennae will at once enable 

 them to be distinguished.
