OF WASHINGTON. 69 



mesosternum. Pronotum sublimate, nearly flat, more than twice as 

 broad as long, widest at the middle; lateral margins not rounded ante 

 riorly, somewhat reflexed and sharply toothed; posterior margin widely 

 sinuate and forming broadly rounded flaps behind the humeri; on disk 

 of pronotum are six longitudinal lines, the last ones much abbreviated ; 

 in the female the median lines approach each other in the middle, while 

 the male has these longitudinal lines parallel. The shield-like scutellum 

 longer than pronotum, with two sunken points at base, and tumidly 

 elevated before the middle. Hemelytra much narrowed towards the 

 tip, reaching the base of the sixth abdominal segment; the male has 

 the hemelytra broader and longer; the corium is at its base only feebly 

 dilated exteriorly, a little upturned, the dilation not extending laterally 

 farther than the pronotum; membrane with the veins dull black, ex 

 cept at base, where there is a small oblong whitish spot. Abdomen 

 long and narrow in the female, shorter in the male; edge of abdomen 

 finely crenulate. 



Length, $ 7.4 mm., <$ 6.8 mm.; width across abdomen, $ 3.4 mm, <$ 

 3 mm. 



Three females and one male, Southern Pines, -N. C., June, 

 1904 (Sherman) ; Greensburg, Pa. (Wirtner). 



Type. No. 9866, U. S. National Museum. 



This species might, at first sight, be easily confused with a 

 dark specimen of Aradus acutus Say. But on closer examina 

 tion a considerable diversity becomes evident. Say's species is 

 larger and broader and has the antennae stouter and longer. I 

 have named the species in honor of Prof. Franklin Sherman, 

 Jr., who has extensively collected the Aradidae of North 

 Carolina. 



Aradus coarctatus, n. sp. 



Body compact, short, nearly subquadrate, the broadest part behind 

 middle of abdomen. Color dark brown, with some paler spots. Head 

 a little longer than broad ; apical process much compressed on the sides ; 

 rounded in front, somewhat tapering towards tip and reaching nearly 

 to one-third the length of the second antennal joint. Lateral spines of 

 head broad at base, a little diverging exteriorly, extending to apex of 

 basal joint of antennae, and having at about the middle of sides a minute 

 tooth ; there is also quite a prominent tubercle in front of the eyes and 

 another obtuse one on the postocular part. Antennae very long and 

 thick in comparison with the size of the insect; basal joint of antennae 

 short, only half as broad as the two following ones; the second joint 

 abruptly pointed towards the base, in length equal to the two last 

 joints; the third somewhat longer than the fourth; joints 2 and 3 

 strongly covered with close, thick, and erect squamules ; terminal joint 

 less stout and more smooth, finely hairy and whitish at tip. Rostrum
