(392) 1. * Chiroleptes Raptor. Robber Chiroleptes. 



C. (Raptor J niger, nitidus ,- prothorace hemelytrisqne obscuris ; his nigro-fuscis, albido lineatis et marginatis ; scutello apice 



albo ; pedibus pallidis ; humeris apice nigricantibus. 

 Robber Chiroleptes, black, shining ; protborax and hemelytra dull ; the latter black-brown, with white lateral margin and 



lines ; scutel! um white at the tip ; legs pale, shoulders blackish at the tip. 



Length of the body nearly 4 lines. 



Two specimens taken in the road from New York to Cumberland-house. 



DESCRIPTION. 



Body black and shining. Head subrhomboidal, connected with the protborax by a long cylin- 

 drical 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 : protborax 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, G but it is distinct. 



CLXXI. * Genus NABICULA. Kirb. 



Promuscis inflexed, not arched, slender, reaching to the intermediate legs, naked, first joint elon- 

 gated. 



AntenncB mutilated in the specimen, inserted before the eyes ; scape elongated. 



Stemmata obsolete. 



Eyes hemispherical. 



Body apterous, linear, head elongated, subtriangular : prothorax bilobed, anterior lobe bell-shaped ; 

 posterior short, flat, scarcely dilated : hemelytra with a very narrow membrane : arms rap- 

 torious. 

 This genus differs from Nobis, as Reduviolus from Reduvius and Chiroleptes from Zelus, in 



not having an arched promuscis ; the first joint of which is longer than it is in Nobis, and naked : 



the stemmata are not visible under a common lens, and the arms are raptorious.
