 by an impressed sinuated black line ; scutellum black with two pale longi- 

 tudinal elevations, thickest anteriorly ; hemelytra with the nervures whiter 

 than the rest of their substance ; with three blackish discoidal dots 

 arranged longitudinally from the middle to the membrane ; thighs dotted

[281.] 392. Chiroleptes raptor Kirby. — Length of body nearly 

 4 lines. Two specimens taken in the road from New York to Cumber- 

 land-House. 



Body black and shining. Head subrhomboidal, connected with the 

 prothorax by a long cylindrical and transversely wrinkled neck, which 

 altogether gives the animal a serpentine aspect ; legs pale ; shoulders 

 much incrassated, blackish at the tip, armed below with several strong 

 spines ; cubits with a single intermediate one ; prothorax bell-shaped, 

 black, dull from inconspicuous pubescence ; scutellum dull, white at the 

 tip ; hemelytra dull from pubescence, blackish-brown, with paler lines 

 which extend into the membrane ; lateral margin white ; abdomen black, 

 with the ventral lateral margin white. 



This species approaches very near to Say's Reduvius raptorius, but it 

 is distinct.

 lines. Taken with the preceding. 



Body apterous, black, without any gloss. Head subtriangular, antenna?
