Abdomen composed of seven segments, the four basal coriaceous, and the three 

 apical corneous, the four basal segments furnished with small inflexed lateral 

 processes. 



Prothora.v (PI. III., A, fig. 2, a) rather small, with the prostcrnum moderate, elevated 

 between the coxae and broadly dilated behind them ; episterna minute ; epimera 

 rather large, enclosing the cosal cavities ; coxal cavities oval, not contingent. 



Pectus with the mesosternttm (PI. III., A, fig. 2, d) moderate, excavated in front; 

 episterna rather large, subquadrate ; epimera moderate, humeral, rather distant 

 from the coxal cavities ; coxal cavities rounded, moderately distant. 

 metaxternum (PI. III., A, fig. 2, g) moderate, transverse, not extending to the 

 sides of the body, posterior margin between the cosse straight ; epistenia broad, 

 rather short, not reaching to the coxffi ; epimera narrow, with their extremities 

 triangularly inflexed, in other parts hidden by the epipleural folds of the elytra. 



]'enter composed of six segments, with the basal segment very large, equal to the 

 other five in length ; the rest as long as each other, apical segment entire. 



Legs anterior with the coxas oval ; trochanters small, trigonal ; femora moderate, 

 simple ; tibiae long and slender, slightly recurved, pilose ; tarsi four-jointed, 

 1 long ; 2 shorter than the first, deeply bifid ; 3 minute ; 4 very long and 

 slender ; claws very slender, faintly dentate at the base beneath. 

 intermediate like the anterior, but rather shorter. 



posterior like the intermediate, but longer, with the tibiae setose on the outer side 

 near the apex. 



Coxa- anterior oval, not contingent, or prominent. 

 intermediate rounded, moderately distant. 

 posterior remote, elongate-oval, reaching to the epimera. 



Sericoderas is the most universally distributed genus of the Cori/loplridie ; its 

 species have been found in every country of both hemispheres into which entomology 

 has yet penetrated. But it is very difficult to determine between true species (or 

 rather the conventional species of science) and local races, and on this account 

 among those described in the following pages some may eventually be found to 

 belong to the latter category.
