CHR YSOMELIDAE .

each side close to eye-margin and each bearing a fine seta ; clypeus sharply 

 triangular, somewhat raised, with a sharp median longitudinal ridge, and a few 

 long scattered setae. Eyes large, occupying a large portion of the head, though 

 not so closely approximate as in the genus Paradibolia. Antennae eleven- 

 segmented, extending a little beyond humerus, slightly thickened towards apex, 

 three basal segments almost without hairs, remainder more hairy ; first segment 

 longest and club-shaped, second small and ovate, third slender somewhat longer 

 than second ; fourth and following segments thickened ; fourth and fifth seg- 

 ments equal, each somewhat longer than any of the remaining segments, which 

 are about equal to one another, terminal segment bluntly pointed. Prothorax 

 transverse, longest in centre ; basal margin 

 bisinuate on each side, and lobed in middle ; 

 sides margined and oblique ; upper surface 

 convex, sloping on each side, very minutely 

 and confusedly punctate, punctures not 

 close together ; each of the four corners 

 with a raised pore for reception of a seta. 

 Scutellum small, triangular, impunctate. 

 Elytra hardly broader at base than pro- 

 thorax, very minutely and not very closely 

 punctate ; on a background of confused 

 punctures ten regular rows, including a 



short scuteUar row, recognisable on each Text-pig. W.-Sphaerophyma insularum, 

 elytron ; these rows not at regular intervals, sp. n. x 14. 



two pairs on lateral area closer to each 



other than those on discal area ; between last row and elytral lateral margin 

 a wide space of confused punctures ; regularity of the rows not well main- 

 tained on apical area, where punctures become more obsolescent, while on 

 basal area rows are more evident. Under side : abdominal sternites minutely 

 punctate and sparsely covered with whitish hairs ; owing to enormous size of 

 posterior femora, which generally remain pressed against abdomen, sternites 

 appear somewhat concave. Elytral epipleurae broad, vertical. Anterior coxal 

 cavities open behind ; intercoxal process of prosternum broad, with surface 

 rough, punctate and margined on each side ; in repose, prosternal process 

 closely opposed to mesasternal process, which is of same width. First abdominal 

 sternite with a median, longitudinal, well-defined oval area. Posterior femora
