AMERICAN HEMIPTERA. 345 



about the size and general as])ect of our northern Nezara hilariis, 

 but with sharp thoracic angles. One specimen, May 2od. 



Arocera apta Walker. — One example, taken August 12th. JNfy 

 specimen is a little larger with the ground color more distinctly yellow 

 than in Distant's figure in the Biologia. 



Banasa alboapicata Stal. — April and July. Three examples. 

 There is also in this lot two specimens of a second species of Banasa 

 I have not yet been able to determine. 



Arvelius albopunctatus De Geer. — Two examples, taken in 

 June. These are unusually large and dark colored. 



Taurocerus edessoides Spinola.— Two taken in May and 

 August. This is a very pretty mahogany-colored species with a 

 yellow tip to the scutellum and elytral horns. 



Brachystethus cribrum Fabr. — Two examples, taken in 

 March. 



Edessa moschus Erich. — I have about a dozen examples of 

 this very pretty species taken in May and June. It is about the 

 size of metatibunda with the pronotal angles produced in long te- 

 rete horns which point well backward and upward. The color is 

 bright clear green above with the tips of the humeral horns black, 

 the elytra dull chestnut with a paler costa, and the legs and antennjt" 

 rufous, inclined to yellow. Beneath yellowish with the sutures and 

 a short parallel vitta within the stigmata clear green ; there is also 

 an indication of a median line, and an oblique vitta either side of it, 

 dull green. 



Edessa quadridens Fabr. — Numbers of this species were taken 

 from April to September. These all agree in having a narrow white 

 line on the base of the scutellum. 



Edessa discors Erich. — I have one male taken June 10th that 

 I identify with this species with little hesitation. It is a trifle larger 

 than metatibunda and less densely punctate on the pronotum and 

 scutellum. The outer angles of the pronotum are sharper with the 

 lateral margins straight and the hind edge more deeply concave 

 before the scutellum. The edge of the abdomen is much more 

 strongly toothed at each segment, even more strongly than in quadri- 

 dens. Color light clear green on the head, pronotum and scutellum. 

 Head with narrow edges and an almost obsolete median line yellow. 

 Elytra castaneous, as iu metatibunda with the nervures pale ; antennte
