name Kochii to this Ja van specimen in the British Museum, which 

 he considered to be specifically identical with the type of the species 

 in the Museum at Berlin. 



Now C. Koch, having before him one of Brandt's types, can not 

 as Dr. Karsch points out, have made the mistake with which he 

 was accredited. It follows, therefore, that the type of Kochii (Butler) 

 is also the type of punctatum (Brandt), whatever be the identity of 

 the specimen in the British Museum to which the name Kochii was 

 attached. As a matter of fact this specimen is wholly different from 

 specimens of punctatum and belongs to the species that I have just named. 



Like all the Javan forms that have been described since Brandt's 

 time this new species may or may not be identical with Sphaero- 

 pœus insignis — a form far too briefly characterised to be recog- 

 nisable without en examination of the type. 



Of all the species known to me it comes nearest to Z. igno- 

 bilis of Butler and Z. glabrata of Newport. In the former howe- 

 ver the lamina of the l ts tergite rises in front much more gradually 

 and the margin of it is evenly thickened throughout; moreover the 

 internal surface of the movable dactylus of the 2 nd pair of copulatory 

 feet is provided with a very large rounded tooth-like prominence — 

 this is absent in Z. nigriceps. — In Z. glabrata (= bicollis, Karsch) 

 the lamina of the first tergite is as large as in Z. nigriceps, but its 

 margin is not thickened and upturned opposite the level of the eye; 

 the immovable dactylus of the first pair of copulatory feet is much 

 shorter and smaller than the movable dactylus and the movable dactylus 

 of the second pair differs from that of Z. nigriceps in the same par- 

 ticulars as does this segment in Z. ignobilis. 



The further affinities of these and other Javan forms will be treated 

 of in my forthcoming revision of the group. 



29. Zephronia rufipes sp. n. 



Java: Tjibodas. One specimen. 



Colour of body a very deep chestnut brown, head redder, antennae 

 and legs yellowish read. 



Head thickly and coarsely punctured as in Z. nigriceps. The dorsal 

 plates more densely sculptured than in Z. nigriceps, the sculpturing 

 being composed of minute punctures and striae and much resembling 

 the appearance of a pig- skin saddle ; a few larger punctures are scat-
