 of the lobes themselves rounded, the interspace narrowesl caudad. 

 Hind tibiae six to eighl -pined externally. Two species are at hand.

The species fusiformis may be considered the type of the genus. 



201. Eujivarus fusiformis sp. nov. 



Size small. General shape fusiform, evenly tapering both cephalad 

 and caudad from the base of the hind femora. I lead small, a little 

 narrower than the front edge of the pronotum, into which it sets 

 almosl or quite to the hind margin of the eyes. Latter prominent, 

 in the female about one-third longer than, in the male nearly double, 

 the anterior edge of the cheeks in length; vertex rather narrow, 

 scarcely as wide (c?) or as wide (9) as the diameter of the rather 

 robust filiform antennae, its posterior portion and anterior part of 

 occiput longit udinally carinate; fastigium a little depressed, triangular, 

 a trifle wider than long, in the middle widely and shallowly sulcate, 

 the surface rather coarsely punctulate, separated from the upper 

 portion of the frontal costa by a well-defined angle; front gently 

 oblique, rather strongly punctulate, frontal costa prominent above 

 between the antenna', at the ocellus and below very much less promi- 

 nent, sulcate and continuous to the base of the clypeus, its sides rather 

 coarse and somewhat sinuose. Antennae heavy, about as long as the 

 head and pronotum together, seventeen-jointed, all but the two basal 

 joint- strongly pitted and hirsute. Terminal joints of palpi a verj 

 little flattened and squarely truncate at apex. Pronotum expanding
