26 Mr. M. Jacoby's Descriptions of New Genera and 



all events {Torodera), the anterior coxal cavities are open 

 as Weise states of his genus, which can therefore be re- 

 tained ; it proves again how easily one insect may be 

 confounded with another if all structural characters are not 

 carefully examined. In regard to my specimens, they 

 vary in not having a black mark at the vertex, in the 

 absence, in some cases, of the small black spot near the 

 scutellum and in the colour of the legs, the posterior 

 femora of which varies from flavous to black. 



GALERUCINyE. 



Oides slie-p'pardi^ sp. n. 



Black, above dark fiilvous!, tliorax very finely punctured, elytra 

 strongly widened at the middle, semi-rugosely punctured, -with 

 several obsolete, raised, longitudinal lines, sides and apex of the 

 abdomen fulvous. Length 13 millim. 



Head fulvous, impunctate, with the exception of a few punctures 

 near the eyes, labrum and palpi black, antennas rather short and 

 stout, the third joint shorter than the fourth, this and the following 

 joints nearly equal, terminal joint elongate ; thorax about twice and 

 a half broader than long, the sides rounded, the angles rather blunt, 

 the surface with an obsolete groove near the lateral margins, finely 

 l^unctured with some still finer punctures at the interstices, scutellum 

 triangular, with some punctures ; elytra much more strongly punc- 

 tured than the thorax with the interstices finely rugose with obsoletely 

 raised longitudinal lines, distantly placed ; breast, abdomen and legs 

 black, the sides and the apex of the last abdominal segment fulvous. 



Hal. Amatongas, Portuguese East Africa {P. A. 

 Shep^jard). 



This is another species allied to O.fcrruginca, Fab., 0. 

 assimilis, Gah., and 0. conradti, Weise, in coloration but 

 differing in the much more strongly punctured and semi- 

 rugose elytra, in which character it resembles 0. palliata, 

 Gerst., but tljat insect is of different colour and has a black 

 head, the coloration of the under-side also in the present 

 species differs from any of its allies. I have received two 

 exactly similar specimens from Mr. Sheppard. 



Hypcracantlia silvaoia, sp. n. (Plate III, fig. 11.) 



Flavous, the vertex, antennte (the basal joints excepted) the apex 

 of the tibise and the tarsi black, elytra metallic blue or cupreous,
