the upper one is produced into a slightly hollow quadrangular process 

 slightly bi-sinuate on the upper edge, serrate on the outer, each 

 interval of the serration bearing a long hair ; labial palpi long, apical 

 joint fusiform but slightly more swollen outwardly than inwardly ; 

 maxillae triquetrous, sharp and curved at the tip and having a very 

 plain inner median tooth ; clypeus nearly as long as the head, concave, 

 broadly vertical in front, not separated from the frontal part by a 

 suture or a carina, frontal part with a slight basal transverse ledge, 

 labrum very narrow, not sinuate ; antennae 10- jointed, the tri-jointed 

 club of the male as long as the pedicel, seventh joint compressed, 

 fitting against the base of the club ; prothorax a little ampliated and 

 rounded laterally in the median part, slightly sinuate in the posterior, 

 and with the basal angles sharp, base strongly sinuate ; scutelluin 

 cordate ; elytra sub-parallel, somewhat convex and covering the 

 greatest part of the propygidium ; pygidium large, bluntly triangular, 

 vertical, plane ; abdominal segments free, the penultimate with a 

 narrow membranous hinge nearly twice as broad as the ante- 

 penultimate ; anterior tibiae bi-dentate outwardly ; tarsi a little 

 longer than the tibiae the intermediate and posterior ones of which 

 have a sharp oblique ciliate median carina on the outer side, claws 

 slender, long, somewhat aculeate underneath at middle. 



The insect included in this genus, and the female of which is 

 unknown, resembles closely the species of Achloa ; the head, pro- 

 thorax, and under side are likewise quite as densely pubescent, but it 

 differs by the 10- jointed antennae, the singular shape of the labial 

 palpi, the vertical pygidium, and the bi-dentate tibiae. 



PSEUDACHLOA LEONINA, n. Spec. 



Male : Very light chestnut, somewhat testaceous, head, prothorax, 

 scutellum and the whole under side clothed with a thick, long, fulvous 

 pubescence almost as dense as in some species of Sparrmannia ; 

 clypeus finely, head more deeply punctured, each puncture bearing 

 a long setulose, erect hair ; prothorax and scutellum finely yet deeply 

 and closely punctured ; elytra sub-parallel, slightly narrower at the 

 base than the basal part of the prothorax the sharp angles of which 

 project a little beyond the rounded humeral part, slightly tri-costulate 

 on each side and faintly striate on each side of the costules, covered 

 with somewhat scattered, somewhat deep punctures, most of which 

 bear a somewhat long, appressed light fulvous hair, arranged in 

 longitudinal rows, the outer margins have a fringe of long, sub-ciliate 

 hairs ; the propygidium is abruptly declivous and like the perpen- 

 dicular pygidium very closely aciculate, both are clothed with a dense
