Figure 104. — Anterior tibia of male (A), clypeus (B), and last visible abdomi- 

 nal sternite of male (C) and of female (Z>) of Chrysobothris lucana. 



median lobe; base strongly, subangularly emarginate on each side, median lobe 

 broadly rounded ; disk uniformly convex, without depressions or callosities ; 

 surface glabrous, rather densely, coarsely, uniformly punctate, intervals densely 

 granulose. 



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

 feebly diverging from humeral angles to behind middle, then arcuately con- 

 verging to tips, which are separately narrowly rounded; lateral margins 

 coarsely serrate posteriorly; basal depressions broad and shallow; humeral 

 depressions broad and inconspicuous; disk moderately convex, without costae 

 or f oveae ; surface glabrous, rather densely, uniformly punctate, more finely 

 toward apices, intervals finely granulose, and each elytron ornamented with 

 violaceous-black spots not extending to sutural or lateral margins, as follows: 

 An oblong one at basal third, a square one behind middle, and a similar spot 

 near apex, united to the postmedian spot by a narrow, obsolete vitta. 



Abdomen beneath coarsely, sparsely punctate, impunctate along anterior and 

 posterior margins of sternites, clothed with a few short, semierect hairs, with- 

 out lateral callosities, intervals obsoletely granulose; last visible sternite 

 broadly, transversely sinuate at apex, with a distinct tooth at each external 

 angle, without a distinct submarginal ridge, lateral margins not serrate ; eighth 

 tergite densely, coarsely punctate, broadly rounded at apex. Prosternum glab- 

 rous, coarsely, sparsely, irregularly punctate, with a rather long, wide, median 

 lobe. Anterior femur with a short, obtusely rounded tooth, which is coarsely 

 dentate on outer margin. Anterior and middle tibiae feebly arcuate, unarmed 

 at apices ; posterior tibia straight. 



Length 8 mm., width 3.25 mm. 



Redescribed from a female in the United States National Museum 

 from Catalina Springs, Ariz., which has been compared with the type 

 by E. Gorton Lmsley. 



Male. — Differing from the female in having the head yellowish green, the 

 antenna brownish cupreous, the last visible abdominal sternite broadly, shallowly, 

 arcuately emarginate at apex, the anterior tibia armed with a short, incon- 

 spicuous tooth near apex, and the posterior tibia armed with a series of small 

 teeth on inner margin. 



Type locality. — San Jose del Cabo, Lower California; type in the 

 California Academy of Sciences.
