552 REDUVINA. 



sometimes with a fuscous streak on each side of the middle line. 

 Scutellum convex, middle black, sides yellow; basal angles de- 

 pressed, the depression defined by a diagonal, curved black line. 

 Elytra pale ochreous, indistinctly fuscous between the nerves, very 

 short, not reaching to the 2nd abdominal segment, posteriorly some- 

 what squarely rounded; Clavus and Corium not perceptibly divided ; 

 Membrane very rudimentary. Sternum narrowly black round the 

 coxa?, broadly black on the sides in continuation of the lateral line 

 on the abdomen. Legs pale yellow ; ihiglis with fine black punctures 

 in rows ; 1st and 2nd pairs with fine, black, transverse lines beneath ; 

 3rd pair not thickened to the apex. 



Abdomen in the with parallel sides ; above, generally with %3 

 brown, longitudinal lines, the middle one narrowest, or entirely 

 black. Connexivum pale-yellow, in the $ very narrow ; in the ? very 

 broad, foliaceous, reflexed, rounded on the margin, generally with a 

 rose-pink streak down the middle. Underside with a narrow black 

 line down the middle, and a broader one on each side. 



Length, 3J 4 lines. 



Common among grass under bushes, from July to October. 



This species, we believe, is frequently passed over as the pupa of 

 N.ferusoTflavomarginatus; but the presence of ocelli and claws 

 shews it is adult. It may readily be distinguished from all our 

 other species by the greater length of the antenna?, and the larger 

 size and falcate form of the lateral processes of the genital segments. 

 Does it ever have developed elytra ?
