posteriorly, the pubescence on the elytra sparser, the tooth on the 

 anterior tibia of the male more triangular, and the sides of the male 

 genitalia more parallel and not so strongly expanded. These two 

 species resemble each other so closely that there may be some difficulty 

 in separating some specimens, and they may prove to be the same 

 species when sufficient material is available for study. 



The name calcarata is preoccupied by . a species described by 

 Melsheimer from Pennsylvania.

(Fig. 7) 



Chrysobothris Usinuata Chamberlin, 1938, Pan-Pacific Ent. 14: 13, rigs. 12-13. 



Figure 7. — Clypeus (A) and last visible abdominal sternite of female (B) of 



Chrysobothris bisinuata. 



Female. — Moderately elongate, rather strongly shining, bronzy brown, with 

 a distinct cupreous tinge. 



Head uniformly brownish cupreous, with a vague, longitudinal carina on 

 occiput and two small callosities on the front ; front nearly flat ; surface 

 coarsely, densely, uniformly punctate, rather densely clothed with long, erect, 

 inconspicuous hairs ; clypeus deeply, broadly, triangularly emarginate in front, 

 broadly rounded on each side. Antennae missing. 



Pronotum one and three-fourths times as wide as long, subequal in width at 

 base and apex, widest at middle ; sides regularly rounded ; anterior margin 

 slightly sinuate, with a vague, broadly rounded, median lobe; base broadly, 

 arcuately emarginate on each side, the median lobe slightly produced and broadly 

 rounded ; disk moderately convex, without depressions or smooth callosities ; 

 surface slightly, transversely rugose, rather coarsely, densely punctate, sparsely 

 clothed with long, erect, inconspicuous hairs, the intervals vaguely granulose. 



Elytra slightly wider than pronotum. nearly twice as long as wide ; sides 

 nearly parallel from humeral angles to apical third, then arcuately converging 

 to tips, which are separately broadly rounded ; lateral margins slightly serrate 

 posteriorly ; basal depressions rather deep and rounded ; humeral depressions 

 broad and very shallow ; disk moderately convex ; surface finely, rather densely 

 punctate, rather densely clothed with moderately long, erect, fine hairs. Each 

 elytron with four smooth, bluish-black, longitudinal costae, which are slightly 

 elevated posteriorly ; first extending from near apex to basal fourth ; second and 

 third extending from near apex to near base, and vaguely interrupted in front 

 of middle and at apical third ; fourth following outline of lateral margin from 

 near apex to middle. 



Abdomen beneath rather densely, finely punctate, sparsely clothed (more 

 densely toward sides) with moderately long, semierect, white hairs, with smoorh 

 lateral callosities, intervals densely granulose; last visible sternite strongly
