extending slightly Over the front coxae. Pronotum sublimate, a little 

 more than twice as broad as long, and shorter than the head ; the sur 

 face rather flat, remotely granulate, more densely on the posterior part 

 of pronotum ; anterior margin straight, the posterior one feebly sinuate ; 

 lateral margins anteriorly somewhat rounded, broadly reflexed and 

 irregularly toothed, the teeth becoming finer towards the humeri; the 

 rounded humeral flaps not prominent, with the inside margin narrowly 

 pale; the longitudinal ridges on disk of pronotum roughly granulate, 

 the two middle ones nearer together than the others, touching the 

 anterior margin, the others interrupted. The scutellum seems rather 

 small, and, as in all three specimens before me the pins are unfor 

 tunately thrust through the scutellum, a definite description of that 

 part can not be given. Hemelytra pale, the edges, veins, and cross- 

 veins strongly granulate, dark brown; the corium on the outer margin 

 nearly straight, extending to base of fourth abdominal segment of the 

 connexivum, at apex pointed; the exterior rounded expansion at base 

 of corium not prominent, the edge a little upturned and finely denticu 

 late; membrane brownish and the veins and spaces around them 

 whitish. Wings iridescent. Abdomen reddish brown, with some paler 

 marking, densely and finely granulate and minutely pubescent ; abdomen 

 , at middle deeply furrowed longitudinally. Genital segment of male 

 abruptly deflexed posteriorly, the genital lobes a little upturned, broadly 

 rounded and incised at the inner sides. Feet yellowish white, with 

 brown bands at middle of femora and tibiae, and at the knees; apex of 

 tibiae and tarsi clouded with brown. 



Length, <$, 4.4 mm. ; width across abdomen, 2.2 mm. 



Three males, California (Coquillett). 



Type. No. 9867, U. S. National Museum. 



This species is easily distinguished from other allied forms 

 by the comparatively stouter antennae and larger head. It 

 resembles A. ornatus Say in the form of the antennal joints 

 and somewhat also in robustness of body, but differs in being 

 considerably smaller and very differently colored, and it has 

 the widest part of pronotum behind the middle, contrary to 

 Say's species, which has its pronotum wider towards the front. 



Aradus compressus, n. sp. 



Body large and thin, broad, ovate; color dull black. Head longer 

 than broad, finely granulate, the granules at the disk in longitudinal 

 rows; the sides inside next the eyes a little excavate, with a deep 

 sunken point before ; anterior process of head very long, narrow, 

 rounded off at tip and reaching beyond base of second antennal joint; 

 the antenniferous spines long and very acute, the outer side straight. 

 Antennae in length about equal to the broadest part of pronotum ; first 

 joint shortest, cylindrical, as stout as the apical joint; the second
