Figure 109. — Clypeus (A) and last visible abdominal sternite (B) of female 

 of Cliryso'bothris prasina. 



Female. — Rather broadly elongate, moderately convex above, moderately shin- 

 ing, uniformly bright green, with a faint golden tinge ; beneath violaceous black, 

 with a greenish reflection at middle, and more strongly shining than above. 



Head bright green, without distinct callosities or longitudinal carinae; front 

 slightly convex ; surface rather densely, coarsely, shallowly punctate, without 

 distinct pubescence, intervals distinctly granulose ; clypeus deeply, triangularly 

 emarginate in front, arcuately rounded on each side. Antenna brownish, slightly 

 bronzy green on basal segments, gradually narrowed to apex ; intermediate seg- 

 ments compact, subquadrate. wider than long, broadly rounded at outer margins ; 

 third segment slightly longer than following two segments united. 



Pronotum nearly twice as wide as long, subequal in width at base and apex, 

 widest near basal fourth ; sides nearly parallel ( slightly converging from basal 

 fourth to apex), arcuately converging near base; posterior angles broadly 

 rounded ; anterior margin nearly truncate, with an obscure, broadly rounded, 

 median lobe ; base broadly, arcuately emarginate on each side, median lobe 

 slightly produced, and subtruncate in front of scutellum ; disk moderately con- 

 vex, without callosities or depressions ; surface finely, rather sparsely punctate, 

 more coarsely densely toward sides, vaguely, transversely rugose, intervals 

 finely granulose. 



Elytra at base slightly wider than pronotum at middle, nearly twice as long 

 as wide ; sides parallel anteriorly, arcuately expanded behind middle, then 

 arcuately converging to tips, which are conjointly broadly rounded ; lateral mar- 

 gins coarsely serrate posteriorly ; basal depressions broad and rather deep ; 

 humeral depressions shallow and broad ; surface glabrous, without costae or 

 foveae, finely, densely, uniformly punctate, punctures finer and sparser toward 

 apices, and intervals finely granulose. 



Abdomen beneath sparsely, finely punctate, glabrous, without lateral cal- 

 losities, intervals indistinctly granulose ; last visible sternite sinuately truncate 

 at apex, without a submarginal ridge, the lateral margins not serrate; eighth 

 tergite densely punctate, broadly rounded at apex. Prosternum glabrous, densely, 

 coarsely punctate at middle, smooth toward sides : anterior margin broadly, 

 arcuately rounded, but not distinctly lobed at middle. Anterior femur with a 

 short, broadly rounded tooth, which is coarsely dentate on outer margin. Anterior 

 and middle tibiae arcuate, unarmed at apices ; posterior tibia straight. 



Length 7 mm., width 3 mm. 



Male. — Unknown. 



Bedescribed from the female holotype, No. 3447. in the Academy of 

 Natural Sciences of Philadelphia. 



Type locality. — "California", no definite locality given, but prob- 

 ably from the northern part. 



Distribution. — The only specimen examined was the type. It is re- 

 corded by Fall (1901) from Pasadena, Calif., in the Fenyes collection, 

 and by Chamberlin (1917, 1926) from Sonoma County and Alameda, 

 Calif.' 



Host. — Unknown.
