 Long. 1| millim. 



Hab. Panama, Bugaba (Champion). 



Antenna? as long as the abdomen and half of the thorax united ; second joint shorter 

 than the third, the latter longer than the fourth, the fifth as long as broad ; the other 

 joints all broader than long, and becoming gradually broader towards the apex, the

Subfam. DRYING. 



The raptorial claws of the fore legs are a distinctive feature of this subfamily. Species

GONATOPUS. 



Gonatopus, Ljungh, Weber's Beitr. zur Naturk. p. 161 (1810).

a. Head and mesothorax punctured.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet [Champion). 



The first four joints of the flagellum are very slender, the other joints thicker but 

 becoming more slender again towards the apex ; the third joint is as long as the

 the head slopes on either side, and is but slightly excavated either before or behind ; 

 the front is a little hollowed on each side of the central keel; the face is semi- 

 perpendicular ; the upper part of the head is finely punctured, glabrous ; the lower
