All previous records of marginalia made by us on the basis 

 of Mexican and Costa Rican material relate to this species. 

 From our present knowledge quadrata has the widest distri- 

 bution of any form of the genus. It occurs from north-central 

 Mexico (Tepic) and northern Yucatan south to at least Ecua- 

 dor and probably Peru, east to Trinidad, where its range 

 touches or overlaps that of 5. marglnella. At its northern lim- 

 it the range extends to the limit of mainland connections (Yu- 

 catan) in the direction of its very near ally, the Cuban conloni- 

 ana. 



There is much size variation in the species, some in the gen- 

 eral form of the pronotum, and to a lesser degree in the pro- 

 notal outline, but the male sex is not difficult to separate from 

 couloniana. The females, on the other hand, are much more 

 troublesome, as Floridan female individuals of couloniana are 

 almost indistinguishable from that sex of quadrata. On close 

 comparison it will be seen that the females of quadrata have 

 slightly more elongate tegmina, with the sutural margin show- 

 ing a less distinct angle at the distal fourth and the marginal 

 field more regularly attenuate. Cuban couloniana females, 

 which show an appreciably wider tegmen, are more readily 

 differentiated.
