longed into two slightly divergent tips; pubescence not so dense as 

 to hide greenish lustre of surface or the punctation, which is not 

 very dense and has a tendency to be striate; some horizontal 

 ridging, pubescence usually brownish with white patches of denser 

 hairs arranged irregularly in four rows on each elytron. Body beneath 

 covered, especially thickly on sides, with white pubescence. Length 

 7.3-10 mm.; width 3.4-4.7 mm.

Remarks: In general, this species has a browner appearance than 



G. aeneipennis because of the pubescence, but otherwise it is difficult 

 to distinguish by its external form. The pubescence on the prothorax 

 tends to form four white vittae. In addition to the differences found 

 in the pubescence there is a more decided hump behind the scutellum. 

 In G. aeneipennis this is not so developed. But the only certain 

 way of distinguishing the two is by the shape of the apex of the 

 aedeagus. In G. fascicularis it is triangular, and in G. aeneipennis 

 it is rounded. There is no definite difference in their distribution nor 

 apparently in their food plant, as in one instance, both species were 

 collected at the same time on cotton at Santa Rita, Venezuela.
