OF WASHINGTON. 231 



in the middle of the scutelluin a reversed _|_-like elevation. Head and the 

 anterior lobe of thorax remote, deeply punctured ; posterior lobe and 

 scutelluin somewhat granulated. Hemelytra shining and rather trans 

 parent; the veins of the corium feebly marked; the inner margin bisinu- 

 ate; base of membrane a little whitish. Abdomen one-third longer than 

 broad ; narrower at base than before the apex and with the lateral mar 

 gins slightly rounded towards the end of the fifth segment, the outer 

 angle of which appears a little prominent; the last abdominal segment at 

 the sides deeply sinuated, the apical part exteriorly rectangular, and 

 acute, the apex of the segment transversely truncate. Ventral part of ab 

 domen ornamentally incrustate; connexivum from above, at the incisures 

 of the first and fifth segments only partly so; the sixth totally, and a few 

 spots of incrustation on the inner margin of dorsal abdomen, next to the 

 membrane. Genital lobes, seen from above, short, triangularly rounded; 

 the middle lobe stouter and a trifle longer. Feet moderately thickened, 

 finely granulated, light brownish, the femora dark brown towards the tip. 

 Length 4.5 mm. ; width across abdomen 2 mm. 



One specimen, a (j> . Tampa, Florida, April 27, 1875 (E. A. 

 Schwarz). 



Type. No. 8155, U. S. National Museum. 



This interesting species comes nearest to Proxius gypsatus 

 Bergroth,* found in Venezuela and Central America, but differs 

 in the form and arrangement of the incrustate prominences and 

 in having the peculiar form of the elevation on the middle of 

 scutellum just reversed from that of Bergroth's species. I take 

 pleasure in dedicating it to my friend Mr. E. A. Schwarz, to 

 whom I am indebted for kind advice in my studies of the Hemip- 

 tera. 



Aradus uniformis, n. sp. 



Body uniformly broad, comparatively short and very thin; color dull 

 black, except the third joint of antennae and the edges of the abdominal 

 segments adjoining the incisures of the connexivum above and below, 

 which are yellowish white. Head, pronotum, and hemelytra more or less 

 granulated in transverse rows, more strongly so on the lower part of scu 

 tellum and finely and irregularly on the underside of the body. Head 

 somewhat longer than broad across the eyes ; the apical process of head 

 long and straight, reaching the second joint of antennas, the sides broad 

 and compressed, the tip bluntly rounded off; antenniferous process of 

 head prominent and very acute, reaching to the middle of the first anten- 

 nal joint; eyes moderately large, strongly protruding from the sides of the 

 head. Antennae about as long as the width of the posterior margin of 

 pronotum, densely covered with fine granules and rather thick, the basal
