Fnlgoridicida gen. nov. 



Head very wide, the hairy eyes extremely large, so that the 

 part between them is very narrow, not more than one-third as 

 wide as one of these; the ocelli are in the form of an isosceles 

 triangle, considerably less wide at the base than high, and the 

 posterior ones are close to the eye-margins. The surface of 

 ihe front is dull, with excessively minute, dense sculpture. An- 

 tennae slender, with simple scape, pedicel longer than the first 

 lunicle joint, the funicle itself with six, mostly elongate, joints, 

 the club as long or longer than the three last of these. Mandi- 

 bles distinctly bidentate at apex, the palpi not examined. Thorax 

 dull, with excessively dense minute sculpture, the axillae touch- 

 ing inwardly. Wings without pattern, hairy, and with very 

 short fringe, a more or less distinct, very narrow, transverse, 

 ol)lique line extending back from near the marginal vein, the 

 latter very short, the stigmal moderately long, the pdst marginal 

 not much developed. Abdomen subtriangular, wide, depressed, 

 foveated on each side towards base, the fovea bearing short 

 bristles ; the ovipositor shortly exserted. 



Male differs by the much more widely separated eyes, the 

 space between these being about equal to the width of one of 

 them; by the elongate funicle joints, mostly twice as long as 

 wide, bearing conspicuous, shortish hairs, the pedicel much 

 shorter than the first funicle joint, the club about equal to the 

 two preceding. The head itself is much more decidedly menis- 

 ciform, the ocelli are placed in the position of the angles of an 

 almost equilateral triangle. Plate XX, fig. 3.
