ELLEMA. 



Size small. Body rather slender, diameter nearly equal, but slightly fusiform 

 in the £ . The head is quite small, sessile and somewhat depressed, being but par- 

 tially visible from above ; the front moderate, vertical and subtufted ; the palpi rather 

 short and slender, but equal to the front ; the tongue equal to palpi ; the eyes very 

 small ; the antennae terminating in a short hook and seta, and longer than the thorax. 

 The thorax is very short and pilose, but little advanced anterior to the base of the 

 fore wings and rather globosely rounded in front. The abdomen is cylindrical, or 

 nearly so, and about thrice the length of the thorax. The anterior wings are equal to 

 the length of the entire body, and are a little more than twice longer than broad, with 

 the tip rounded, and the hind margin entire and obliquely convex, the inner angle 

 rounded and the inner margin straight. Hind wings rounded at the tips.
