oblique spine externally ; tarsi sulcate externally, anterior in male 
with three basal joints dilatate, and furnished below with an 
oblique row of squamulse on each side; 4th joint of anterior tarsi 
decidedly bilobed, of middle emarginate, hardly bilobed, of posterior 
not emarginate, the projecting hairs on each side equal. Length 
9, breadth 3^ mm. 
This insect is winged ; it does not appear to differ in any 
character from Platynus , but I have described it more fully than 
usual in regard to features more of generic than specific value, 
so that its exact position in regard to Colpodes , a genus I am 
unacquainted with, may be evident.
