CANOPUS CAESUS Germar 



ChlaenoGoru caesus Gemab, E. F., Zeitsclir. f. Ent., vol. 1, pt. 1, 1839, p. 23 

 [Middle America]. 



Numerous specimens showing considerable variety of metallic 

 reflections; tibiae and tarsi usually, and sometimes all of legs, testa- 

 ceous; antennal segments 1-3 usually pale, as is also more or less 

 basally each of 4 and 5 ; 3 is sometimes darkened for l^-% its length 

 from base, and 4 and 5 are sometimes wholly dark. Fore wing as in 

 figure 20; female genitalia from below as in figure 31. Length, 

 6-6 mm. 



The first specimen labeled type in the Museum fiir Naturkunde 

 Berlin, and the only specimen at Lwow (Mus. Johann Kasimir 

 Universitat) agree as to species, indicating the correctness as well as 

 the desirability of selecting the former as holotype of the species. 

 The Berlin specimen is labeled Para, Seiber, and that at Lwow, 

 Brazil; the Berlin series contains two of the present species and 

 three of orMculaH-g; other material examined includes specimens 

 from Santarem, Brazil, April, May, June, July, 1919; Nova Olinda, 

 Rio Purus, Brazil, June, 1922, S. M. Klages; Mana River, French
