F. TOLUL^, I^ec. Dark brown, polished, pubescence coarse, 

 long, abundant on every part of the body; antennae and legs 

 yellowish. Length 2.1 mm. Plate XII., Fig. 125. 



Head without the eyes, as long as wide, eyes large, promi- 

 nent, tempora very convergent, nearly transverse, as long as 

 the eye, with the posterior part of the eyes and the base form- 

 ing a regular arch; sides near the eyes sinuate, frontal margin 

 sinuate, supra-antennal tubercles strong; in a line with the 

 middle of the eyes are two small, circular fovese, mutually 

 three times more distant than either from the eye, frontal 

 fovea oblong, large and deep; space separating the three 

 foveas slightl}' elevated. Antennce half as long as the entire 

 body, first joint cylindrical, strong, twice as long as \f ide, flat- 

 tened above; second shorter, oval, one-half longer than wide; 

 third to tenth gradually increasing in width, third smallest, 

 longer than wide, eighth slightly transverse, ninth as thick as 

 the first; tenth a little larger transversely oval, one-fourth 

 wider than long, eleventh ovate-acuminate, one-half longer 

 than wide. Last palpal joint twice as wide as long, oval, 

 somewhat more arcuate inside, the second joint larger than 

 the third; on the under side of the head, behind and below the 

 eyes each side, is a small acute tubercle. Prothorax sub-glo- 

 bose, widest in the middle, nearl}- as long as wide, the base 

 twice the width of the neck; the discal punctures are hardly 

 visible, the basal transverse excavation and lateral fovese deep. 

 Elytra much depressed, the base, sides, and posterior limit 

 nearly straight; sides and tip declivous, discal and sutural 

 lines with deep foveolas before the middle, only one interme- 

 diate puncture near the base; the disk, across the shoulders, is
