Coptopteryx argentina Burmeister.

 Coptopteryx argentina Sauss. Bull. Ent. Suisse, iii, 66, 1S69. 

 Coptopteryx argentina Westw., Synopsis Mant. , 6, 1889. 



Five males, five females, December to March. 



The males exhibit some variation in size, one measuring but 43 

 mm. in length of elytra and the pronotum is only 16.5 mm. long. 

 But the shape and venation of the wings of this small specimen shows 

 it to belong to this species. Two of the large specimens exhibit vena- 

 tional variation in that the wing in the first and second axillaries of one 

 merge 8.5 mm. from the tip, while in the other specimen the merg- 

 ing of these veins occurs at a point 24 mm. from the tip of the wing, 

 the latter distance apparently the normal one.
