UMGENIA, nov. gen. 



Ligula fused with the paraglossae, and of the same shape as in 

 Callida and Lipostratia ; mentum deeply emarginate and without 

 any median tooth, lateral lobes sharp, diverging inwardly and 

 broadly triangular ; last joint of both maxillary and labial palpi 

 fusiform, but not quite acuminate at tip ; maxillae falcate ; mandibles 

 very robust, much curved outwardly and very distinctly carinate on 

 the upper side, sharp inwardly but not projecting much beyond the 

 labrum, which is of normal size, transverse, and bear six long apical 

 setae ; antennae short, reaching the humeral angle only ; eyes very 

 large, spherical, and with two supra-orbital setae on each side ; 

 prothorax short, sub-cordiform ; scutellum sharply triangular ; elytra 

 broader than the prothorax, ampliate past the middle, truncate but 

 not sinuate, and depressed ; legs somewhat short, tarsal joints 

 similar to those of Callida, apical one lobate, claws with six long 

 robust teeth on each side. 



Shorter and more massive than Calleida ; is at once distinguish- 

 able by the robust shape of the mandibles and the brevity of the 

 antennae. 



Umgenia formidulosa. 



Rufous, shining; the eight apical joints of the antennae are black, 

 and the elytra piceous-black with a lateral and apical narrow rufous 

 margin, and also a large juxta-sutural median patch somewhat 

 rufescent ; head smooth but punctate along the anterior part of the 

 eyes ; prothorax broader by one-fourth at its widest part than long, 

 truncate at base and apex, ampliated and rounded laterally from the 

 anterior angle to two-thirds of the length, and straight from there to 

 the posterior angle, which is sharp, outer margin sharp, recurved, 

 disk smooth, median longitudinal grooved line not deep ; elytra 

 one-third wider at the base than the prothorax at its widest part, 

 gradually ampliated from the humeral angle to two-thirds of the 

 length, where it is twice as wide, depressed, finely puncato-striate 

 with the intervals plane and smooth. Length 9 mm. ; width 4 mm. 



Hab. Natal (Umgeni River).
