Aradid.e 



1. Aradus aeqiialis Say. — Mr. Heidemann has sent me a speci- 

 men of A. duryi Osb., communicated to him by Mr. Dury. I 

 quite agree with Heidemann in considering this species a synonym 

 of aeqiialis. 



2. Aradns mofitanus, n. sp. — Ovate (9), finely granulated^ 

 uniformly dark brownish black including legs and antennae. Head 

 somewhat longer than broad and as long as the pronotum in the 

 middle, with two parallel longitudinal impressions, the tubercle 

 near the anterior angle of the eyes low and obtuse, antenniferous 

 spines a little divergent, not quite reaching the middle of the first 

 antennal joint and with a small tooth on their outer margin, rost- 

 rum reaching the anterior coxae, antenna^ moderately robust, a 

 little more than half as long again as the head, second joint 2^ 

 times longer than first and a little longer than half the breadth of 

 the head (including eyes), a little thicker at apex than at base, 

 third and fourth joints taken together scarcely longer than second, 

 third joint a little thicker than second, fourth conspicuously narrow- 

 er and shorter than third. Pronotum kidney-shaped but with a 

 short lobelet anteriorly on each side near the neck of the head, 

 a little narrower than the hemelytra between their dilated sub- 

 basal part and a little more than twice broader than long in the 

 middle, its greatest width in the middle where the lateral margins 

 are rather broadly rounded and from where they are strongly 

 convergent toward the apex, much less so toward the base, the whole 

 lateral margins distinctly crenate, the four median discal ridges 

 subequally distant at their base, the inner pair reaching the anterior 

 margin, thicker and more approximated before the middle, the 

 outer pair not reaching the apical m.argin. Scutellum a little 

 longer than the pronotum in the middle, with a blunt median 

 longitudinal keel in the basal half, the lateral margins convergent 

 from the base to beyond the middle, then slightly rounded to the 

 apex. Hemelytra ( 9 ) slightly passing the base of the dorsal 

 genital segment, exocorium moderately dilated and reflected in
