26 CLAVELLARIA AMERIND. 



from that found in Cimbex and TricMosoma, save that 

 the second recurrent nervure is received at a greater 

 distance from the first transverse cubital. 



Clavellaria contains only one species. It comes 

 nearest to Trichiosoma, but its body is longer and 

 narrower, the abdomen especially being longer com- 

 pared to the length of the head and thorax. The 

 wings are shorter compared to the length of the body ; 

 the mandibles are longer and more projecting, the legs 

 are more slenderly built and have no teeth. The tarsi 

 are shorter compared to the tibiae, and their patellae are 

 much less strongly developed. The antennas have one 

 joint less before the club, there being only the fourth 

 joint between it and the third, while it has no divisions.
