Figure 53. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of ChrysolotJiris femorata. 



Pronotum twice as wide as long, distinctly wider at base than at apex, widest 

 near apex ; sides nearly parallel along middle, converging posteriorly and ante- 

 riorly ; anterior margin broadly, arcuately emarginate, without a distinct median 

 lobe ; base arcuately emarginate on each side, median lobe strongly produced and 

 broadly rounded ; disk slightly uneven, with a faint, longitudinal, median depres- 

 sion ; surface rather densely, irregularly punctate, with numerous slightly elevated, 

 smooth spaces. 



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

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

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

 serrate; basal depressions broad and deep; humeral depressions broad and shal- 

 low; surface glabrous, coarsely, rather densely, irregularly punctate. Each 

 elytron with four more or less distinct, longitudinal, smooth costae, connected to 

 one another by transverse, irregular, smooth spaces, and with two slightly de- 

 pressed, irregular, transverse foveae, one near middle, the other at apical third. 



Abdomen beneath sparsely, coarsely, irregularly punctate, sparsely clothed 

 with short, semierect, white hairs, without distinct lateral callosities, intervals 

 finely granulose ; last visible sternite semicircularly emarginate at apex, with a 

 serrate submarginal ridge, lateral margins coarsely serrate ; eighth tergite thick- 

 ened at apex, with a deep, narrow, median notch, surface coarsely, sparsely punc- 

 tate. Prosternum coarsely, densely punctate laterally, smooth at middle, rather 

 densely clothed with long, erect hairs; anterior margin without a median lobe. 

 Anterior femur with a large, obtuse tooth, which is slightly dentate on outer 

 margin. Anterior and middle tibiae strongly arcuate, armed with numerous 

 small teeth on inner margins ; posterior tibia straight. 



Length 12 mm., width 5 mm. 



Female. — Differing from the male in having the antenna uniformly reddish 

 cupreous, sometimes with a faint greenish tinge, the last visible abdominal 

 sternite broadly, arcuately emarginate and tridentate at apex, with the median 

 tooth long and narrow, and the lateral tooth on each side broadly rounded, the 

 eighth tergite coarsely, continently punctate, with strongly elevated median and 

 lateral carinae, deeply depressed between the carinae, and with a deep, narrow, 

 apical notch, and the anterior and middle tibiae slightly arcuate, and unarmed on 

 inner margins. 



Redescribed from a male and female from Fort Valley, Ga., in the 

 United States National Museum.
