JAMES A. G. REHN 237 



The present species differs iromA.hamiUoni (Rehn), from Cuba, 

 in the bisinuate caudal margin of the pronotum; from catharina 

 Shelford, from Santa Catharina, Brazil, in the emarginate apex 

 of the supra-anal plate of the female, and from carinulata (Saus- 

 sure), from Central America, in the larger size, distinct venation 

 of the tegmina, more numerous femoral spines and differences in 

 the coloration. 



The localities given above are all known for the species.

 XX, p. 356. [Mexico; Cuba.^^] 



Para, Para. (C. F. Baker.) One female. 

 This specimen, while slightly larger, appears inseparable from 

 Mexican material. The penciling of the humeral trunk is less 

 distinct in the Para specimen and the specklings of the pro- 

 notum heavier and more numerous. The species has been re- 

 corded from Ecuador l)y Giglio-Tos, Ijut not previously from 

 eastern South America.

[Bartica, British Guiana.] 



Para, Para. (C. F. Baker.) One male, one female. 



The above synonymy has l)een brought about by Shelford 's 

 redescription^^of DeGeer's type resuscitating the name abdonten- 

 nigrum, which was unrecognized for over a century. The pres- 

 ent specimens and the type of aborfinpenmi fully accord with Shel- 

 ford's description. 



Para is the most southern point from which the species is 

 known.
