extremity V-emarginate, the styles very brief. In structure the 

 abdomen is lamellate as in the female, but in a slightly more re- 

 duced fashion; the dorsal black pattern is some^^hat different; second 

 segment with a transverse bar caudad, third segment with an arcuate 

 figure distad taking up about two-thirds of its surface, fourth seg- 

 ment similarly but more completely occupied, fifth segment com- 

 pletely colored except that proximo-mesad the tone is weaker and 

 brownish, sixth segment broadly bordered laterad and caudad with 

 black, seventh segment distinctly and eighth and ninth segments- 

 faintly bordered caudad with blackish: venter of the abdomen with 

 the structure of the segmental margins as in the male. Limbs of 

 the type found in the female but much more slender. 



Measurements of the described specimen: length of body, 41 mm.; 

 greatest width of head across eyes, 5.8; length of pronotum, 11.5;: 

 greatest width of pronotum across expansion, 3.5; length of tegmen,. 

 38.6; greatest width of tegmen, 11.5; length of cephaUc femur, 10;^ 

 length of caudal femur, 7.5.

The range of this species is now known to extend from the Misiones,. 



northeastern Argentina north to Goyaz, Brazil. 



Oxyopsis oculea new species. (Plate X, flgs. 5, 6 and 7.) 



A member of the section of the genus having produced and acute 

 apices of the wings, and related to 0. ruhicunda (Stoll), from the 

 Guianas, but differing from that species in the female sex in the less 

 elongate pronotum, more decidedly trigonal sectional form of the 

 shaft of the same, in the more produced (laterad) eyes, in the some- 

 what narrower marginal field of the tegmina, in the reduction in 

 number and size of the hyaline areas of the discoidal field of the 

 same, in the more acute tegminal apices, in the slightly more acumin- 

 ate apices of the wings and in the relatively shorter median and 

 caudal limbs. We are unable to compare the male very satisfac- 

 torily with nibicunda, owing to a lack of material of that sex of the 

 older species, and the rather poor character of the available descrip- 

 tions and figures of the same.
