margins moderately reflexed and sinuate, the anterior angles 

 strongly, broadly, obliquely produced, the posterior angles 

 slightly notched or angulated; scutellum broad, about as 

 long as the corium, its lateral margins concavely sinuate, its 

 apex angularly rounded; membrane short, reaching the apex 

 of the abdomen, longitudinally veined ; body beneath imper- 

 fectly seen in carded type; legs of moderate size. 



Allied to Crollius, Dist., in general appearance and 

 structure, but the antennae five-jointed, head strongly 

 sinuate and reflexed, antenniferous tubercles not spinous ; 

 pronotum shorter and broader. 



Neocrollius natalensis, sp. n. 



Ochraceous, thickly darkly punctate ; antennae ochra- 

 ceous, apical joint piceous ; pronotum coarsely darkly 

 punctate, between the humeral angles slightly, transversely, 

 irregularly, palely, ochraceously levigate, the cicatrices 

 broadly irregularly triangulate, piceous and narrowly mar- 

 gined with pale ochraceous, the lateral and anterior margins 

 and the anterior angles pale ochraceous ; scutellum finely 

 wrinkled on basal half, the dark punctures a little more 

 dense on apical half, a broad sublevigate obscure central 

 fascia neither reaching base nor apex, on basal margin a 

 central short line and a small spot near each basal angle pale 

 levigate, the basal angles foveate and black; corium more 

 finely punctate, the basal costal margin pale ochraceous ; 

 membrane pale fuscous with the veins piceous ; sternum 

 ochraceous, thickly darkly punctate ; abdomen with the 

 punctures paler and apparently with a broad central black 

 fascia imperfectly seen in carded specimen ; spiracles piceous; 

 le»s stramineous, apices of tibiae and the tarsi blackish ; 

 other structural characters as in generic diagnosis.

Head longer than broad, lateral margins moderately 

 sinuate, apex broadly subtruncate, lobes of equal length, 

 ocelli near base, a little nearer eyes than to each other ; 

 antennae with the basal joint not reaching apex of head,, 

 second joint longer than third and subequal to fourth ; pro- 

 notum including lateral angles about twice as broad as long, 

 the lateral margins concavely sinuate, lateral angles broadly 

 obtusely angularly prominent ; scutellum not longer than
