In form of thorax resembles Discoderus arcuatus ; but the male has the four anterior

tarsi normally dilated, and furnished with squammules in double series beneath.

This species, unknown to me, must approach the genus Discoderus still more closely 



than the foregoing 

 arcuated.

Apparently closely allied to iS. curvipes ; without the scaly clothing of the soles of the 

 male tarsi (which appears to be scarcely so regular as in the typical Selenophori and in 

 Harpalus), I should have placed this species in Discoderus. I have seen one example 

 only.

DISCODEEUS.

This curious genus seems peculiar to North America, about half the described species 

 being found in the United States, and half in Mexico ; but the genus Anisocnemus of 

 Venezuela is very closely allied to it. In the typical species, as Dr. Horn states, the 

 male has a few squammules on the soles of the dilated tarsi. But the Mexican species 



appear to be destitute of squammules. The tarsal joints in the female are bordered
