This group is capable of subdivision in the following manner: 



1. — Abdomen glabrous at middle and with very few punctures. 

 Elytra with basal white spot. 



Females with a distinct sinuation limited by an evident angulation or 



tooth. Eiytral markings rather slender, not confused A, 



Females with a feeble sinuation only. Eiytral markings broad and 



confused B, 



Elytra without basal spot. 



A strong sinuation in the female with moderate tooth, markings slender.C. 

 J. — Abdomen pubescent at middle and finely and rather densely punctured. 



A small basal spot joined to the humeral lunulo, markings broatl and 

 confused D» 



The species of section A of this group contains five species, one of 

 which however, may be viewed with some doubt. {Magdahnse). The 

 following remarks with the figures already published, will assist in 

 identifying them. 

 Humeral lunule oblique, suddenly hooked at tip. 



Median band sinuous and long cupra^cens, macra, pnrifana. 



Median band short, terminated by ashort hook Wapleri. 



Humeral lunule curved as in repanda. 



Median band moderately long, not sinuous at tip; a sutural stripe near 



the base Magdal«*n«e. 



The first three species have always proven very troublesome 

 to all students. They have similar eiytral markings, broader in 

 cuprascens. 



pnritana. 

 Bronzed. Elytra more 

 finely and less densely 

 punctured. 



Strongly sinuate, tooth 

 rectangular. Tip ob- 

 tusely truncate. Fig. 



cnprai^eens. 



Color — Cupreous. Elytra 



coarsely and rather 

 densely punctured. 



Elytra 5. — Strongly sinuate 

 near the tip, tooth 

 acute and* promi- 

 nent. Tip rounded, 

 n. I, fig. 21. 



Elytra % . — Tip obtuse. 



22. 



macra. 



Bronzed. Elytra fine- 

 ly and sparsely punc- 

 tured. 



Less sinuate, tooth 

 rather obtuse. Tip 

 slightly prolonged, su- 

 ture spinous. Fig. 23. 



Tip slightly prolonged. 



Tip subacute. 



An additional character of less value is seen in the median band, 

 which bears at its tip in cuprascejis and macra a broad, triangular 

 spot, while m puritaua the tip is scarcely at all dilated except in very 

 rare instances. The elytra of cuprascens and macra have been figured.

The female is unknown, but the species belongs here rather than 

 with hlanda. The figure gives the markings very accurately.
