Table of the Species of Anomala. 



1. Metasternum not protuberant, middle coxa narrowly separated * 2. 



Metasternum protuberant, middle coxae rather widely separated (subgenus 



Spilota) 19. 



2. Tarsal claws in part cleft, sometimes very feeble (subgenus Anomala) 3. 



Tarsal claws all simple (subgenus Rhombonyx) 16. 



3. Hind tibise (female) shorter than the femora, very broad, triangularly widening 



to apex ; first joint of middle tarsi longer than second ; color testaceous, head, 

 two oblique apical thoracic spots of irregular outline and suture darker. 



tibialis Schaef. 

 Hind tibiae as long or longer than the femora, of usual form 4. 



4. Pygidium punctate, punctures well separated! 5. 



Pygidium rugose Ii. 



5. Thorax unicolorous 10. 



Thorax bicolorous, black with side margin more or less testaceous, or testaceous 



with one or two apical black spots 6. 



6. Elytral intervals of equal width, convex, rugose, only the subsutural wider and 



with confused punctuation ; striae impressed, almost impunctate ; clypeal mar- 

 gin widely reflexed ; color testaceous, head and two spots at apex of thorax 



darker antennata Schaef. 



Two or more of the elytral intervals wider than the others and with confused 

 punctuation, clypeal margin narrowly reflexed 7. 



7. Thorax testaceous with two darker apical spots 8. 



Thora.x testaceous with one apical spot, or black with sides paler 9. 



8. Front tibiae bidentate, elytra coarsely punctate and subrugose, the costse indistinct, 



obscured by the coarse punctuation ; color testaceous, two apical thoracic spots 



and suture darker parvula Burm. 



Front tibiae tridentate, the upper tooth distinct in the larger specimens, in the 

 smaller specimens more feeble ; the elytral costte, as well as the geminate rows 

 of punctures enclosing them, well defined ; color testaceous, head, two thoracic 

 spots, elytral suture and side margins black or piceous flaviUa Bates. 



9. First joint of middle tarsi very distinctly shorter than second; outer claws of front 



and middle tarsi in the male very feebly cleft, the upper division fine and thin 

 and on the front claw far removed from the tip of the lower division ; color 

 testaceous, head, a subtriangular apical thoracic spot, suture and margin of 



elytra darker centralis Lee. 



First joint of middle tarsi as long or longer than second ; outer claws of front and 

 middle tarsi in the male distinctly cleft, the upper division as long as the lower, 

 or slightly shorter ; color variable, from testaceous, thorax with large apical spot 

 and humeral callus of elytra darker to elytra black, with faint traces of longi- 

 tudinal testaceous lines and thorax black with side margins testaceous. 



inconstans Burm. 



* In polychalca the middle coxae are more widely separated than in the rest of 

 the species, but the metasternum is not protuberant. 



t In some specimens of inconstans and peninstilaris the pygidium is feebly 

 rugose.
