Figure 98. — Clypeus (A) and last visible abdominal sternite of male (B) of 



Chrysobothris scitula. 



Male. — Rather narrowly elongate, slightly convex above, strongly shining ; 

 surface above bluish green, each elytron with three purplish-brown spots; be- 

 neath bluish black, with a faint violaceous reflection, the legs more or less 

 bronzy green. 



Head green, with a faint yellowish tinge, and a vague longitudinal carina 

 on occiput; front nearly flat; surface coarsely, deeply, irregularly punctaio, 

 indistinctly pubescent ; clypeus rather deeply, broadly, subangularly emarginate 

 in front, nearly truncate on each side. Antenna cupreous, with basal segments 

 yellowish green, slightly narrowed to apex ; intermediate segments not compact, 

 subtriangular, as wide as long, broadly rounded at outer margins ; third segment 

 as long as following three segments united. 



Pronotum three-fourths wider than long, wider at base than at apex, widest 

 near apex; sides strongly rounded near apices, obliquely converging from near 

 apical angles to posterior angles ; anterior margin strongly sinuate, with median 

 lobe broadly rounded ; base broadly, arcuateiy emarginate on each side, median 

 lobe slightly produced, broadly rounded in front of scutellum ; disk slightly 

 convex, without depressions or callosities ; surface coarsely, deeply, uniformly 

 punctate over entire surface, vaguely, transversely rugose, the intervals finely, 

 densely granulose. 



Elytra at base distinctly wider than pronotum at base, nearly twice as long 

 as wide, widest behind middle; sides diverging from humeral angles to behind 

 middle, then arcuateiy converging to tips, which are conjointly broadly rounded ; 

 lateral margins coarsely serrate ; basal depressions broad and moderately deep ; 

 humeral depressions barely indicated; surface glabrous, without discal foveae 

 or longitudinal costae, coarsely, deeply, densely punctate, slightly rugose basally, 

 intervals densely granulose, each elytron* ornamented with purple-brown spots 

 as follows : A large round spot at basal fourth, a large triangular spot at middle, 

 and a smaller triangular spot at apical fourth. 



Abdomen beneath coarsely, sparsely, shallowly, irregularly punctate, indis- 

 tinctly pubescent, without lateral callosities, intervals densely granulose; last 

 visible sternite transversely sinuate at apex, with a slightly elevated submargi- 

 nal ridge, lateral margins slightly sinuate but not serrate; eighth tergite 

 coarsely, densely punctate, densely granulose, broadly rounded at apex. Proster- 

 num coarsely, densely punctate, nearly glabrous ; anterior margin with a distinct, 

 long, median lobe. Anterior femur with a large, acutely triangular tooth, 

 which is obscurely dentate on outer margin. Anterior and middle tibiae arcu- 

 ate, the former with a rather long, narrow dilation at apex, the latter dilated 

 at apex ; posterior tibia straight. Genitalia similar to those of concinnula. 



Length 6 mm., width 2.5 mm.
