Poiiipoiiia iiiipcratoria (Westwood). 



Hab. Borneo, Telok Ayer (Muir). Previously also from Malay 

 Peninsula, Java, and Sarawak. 



FAMILY CERCOPIDAE. 



Subfamily Machacrotiiiae. 



I consider that the Machacrotiiiae are simply Ccrcopidae with 

 simplified venation, both of tegmina and wings, and with more 

 or less produced nota ; they are a side branch of the Ccrcopidae, 

 and in no way a link between them and the Mcuibracidae, which 

 are a development of the Tctigoniidae (or "Jassidac") and lie 

 right on the other side of the latter. The Mcuibracidae are simply 

 Tctigoniids with modified face and legs, and with a more or less 

 ornamental nota. This development is merely analogical be- 

 tween the MacJiacrotinac and Mcmbracidac, and in no zvay homo- 

 logical, as in the former it is mesonotal, in the latter pronotal ! 



Pcctinariophycs Kirkaldy. 



The hind tibiae are bispinose, but the basal one is minute. 



Polychaetophycs Kirkaldy. 



This genus is very close to Machacropsis Melichar, and may 

 prove identical. The head, however, is much shorter and broade-", 

 and very much more declivous, the face is broader and shorter, 

 the scutellum is scarcely, or not at all, grooved mediolongitudi- 

 nally, and the apical cells of the tegmen are four or more, though 

 two or more of these are small. 



Machacrota nwJuccana sp. nov. 



Apparently allied to M. cnsifcra Burmeister, but the scutellum 

 is tricarinate, its process much more arched, and the pronotuin 

 is not striped.. Purplish piceous ; the pronotum browner along 

 the posterolateral margin, and the scutellum with a short whitibli 

 longitudinal streak basally on each side; the process is brownish - 

 yellow. The face is unicolorous, but has thin, lateral, silvery, 

 radiating lines. Fore and middle legs brownish-yellow ; hind legs 

 brownish-piceous. Sterna and base of abdomen beneath partly 

 pale. Tegmina yellowish-hyaline, veins brownish-yellow, the 

 costa and subcosta darker for the greatest part of their length. 

 Wings hyaline, veins blackish-brown. Vertex scarcely, though 

 very nearly, as long as in cnsifcra, rounded anteriorly, rather 

 longer than wide between the eyes (or at least as long). Vena-
