114. Copiocera surinamensis Rehn. 



Copiocera surinamensis Rehn, Proc. Acad. Nat. Sci. Philad., Mch. 1913, pp. 94-96, 

 figs. 7, 8. 



I am referring a single male specimen belonging to this genus to 

 Rehn's C. surinamensis. It is from the Mana River in French Guiana, 

 where it was taken in May, 1917. C. M. Ace. No. 6008. 



Its measurements are: Length of body, cf,, 30 mm.; of pronotum, 

 4.75 mm.; of tegmina, 25 mm.; of hind femora, 13.5 mm. In color 

 it agrees well with Rehn's description of his female type, save that the 

 anterior and median femora are brighter, almost blood-red. 



115. Copiocera lepida Gersta2cker? 



Copiocera lepida Gerst.'ECKER, Mitth. Ver. Neu-Vorpomm. u. Riigen, XX, p. 34, 

 no. 28 (1889); KiRBY, Syn. Cat. Orth., Ill, p. 420 (1910). 



A single female specimen of a Copiocera found in the collection now 

 being studied is referred with some hesitation to C. lepida of Ger- 

 staecker. It might, however, be referable to C. prasina Rehn, the 

 description of which I did not have before me at the time of deter- 

 mining the material in hand. This specimen comes from Benevides, 

 Para, Brazil, near the place where Rehn's type was obtained. It 

 was taken by S. M. Klages in October, 1918. C. M. Ace. No. 6174. 



* Rehn's C. prasina possibly belongs about here in the table.
