PROCLETODEMA, n. gen., 



Mentum, maxillae, and palpi of Parachlcenius, but the tooth in the 

 mentum is more sharply bifid ; the paraglossae are also similar, but 

 the ligula instead of being straight and truncate is distinctly diagonal 

 at apex and quite perpendicular laterally ; labrum broader than long 

 and deeply emarginate, epistoma very deeply incised in front, the 

 incision is U-shaped, and the suture with the frontal part is not discer- 

 nible, the incision is filled with a membranous integument ; head 

 long, slightly narrowed behind the eyes which are moderately large 

 and bulging, and have one supra-orbital seta placed at the back of 

 the eye ; antennae of Parachlcenius ; prothorax sub-trapezoid and with 

 a seta on the posterior angle ; elytra not broader than the prothorax 

 at its widest part, parallel, not convex, sinuate behind, striate and 

 with a series of distant punctures on the third, fifth, and seventh 

 intervals ; legs moderately long, intermediate tibiae a little incurved,, 

 with the outer ridge very spinose. 



The extraordinary shape of the epistoma may be of a terato- 

 logical nature ; apart from that, the distinction between this genus 

 and Parachlcenius consists in the more massive head, the difference 

 in the shape of the ligula, the more parallel elytra, which are not 

 broader than the prothorax, the smooth intervals of elytra, and 

 the presence of three series of punctures on the alternating 

 intervals ; in Parachlcenius the intervals are covered with closely 

 set briefly setigerous punctures, and there is no trace of series of 

 punctures on the alternating ones ; the intermediate tibiae are also 

 not incurved. 



Procletodema parallelum, 

 Plate XI., fig. 10. 



Dark brown, glabrous, shining ; head smooth with two broad but 

 very shallow impressions in the anterior part ; prothorax truncate at 

 base and apex, but with the anterior angles produced, very slightly 

 rounded from the apical angle to two-thirds of the length, and from 

 there a little attenuate and slightly sinuate as far as the basal angle 

 which is sharp, one-sixth narrower at base than at apex, and one- 

 fourth longer than broad, it is depressed, has a median narrow longi- 

 tudinal groove, and a moderately deep impression on each side of 

 the base, the outer posterior margin is very slightly reflexed ; 

 scutellum broadly triangular ; elytra not broader than the prothorax
