NO. 2150. SOME NEW HETER0PTER0U8 UEMIPTERA—BERGROTU. 235 



margin of mesosternum, first joint reaching middle of eyes, second 

 and third subequal in length, each a little longer than first and a 

 little shorter than fourth. Pronotnm gently sloping, strongly nar- 

 rowed from the subacute very slightly prominent humeral angles to 

 the apical collar which is as long as the postocular part of the head, 

 well defined posteriorly by an impressed line continued through the 

 sides and prosternum, not callose though transversally convex, punc- 

 tulate the same as the disk of the pronotum, with its lateral margins 

 parallel; calli confluent, forming a transverse impunctate area im- 

 mediately behind the collar and reaching the sides, in the middle a 

 little longer than the collar but narrowing toward the sides, to- 

 gether with the collar in length occupying scarcely more than the 

 apical third of the pronotum ; lateral margins from the base of the 

 collar to the humeral angles straight, obtuse, vertically rounded but 

 with a slightly raised impunctate line separating the pronotum from 

 the propleura and visible only from the side, basal margin rounded, 

 covering the base of the scutellum. The uncovered part of tlie scu- 

 tellum half the length of the pronotum without collar, a little broader 

 than long, the extreme tip a little callose. Xyphus of prosternum 

 with a small median impression, very finely margined, blunt at 

 apex. Orificia distinct, rounded. Hemelytra passing apex of ab- 

 domen, veins of corium and clavus not distinct, cuneus moderately 

 inclined, longer than broad, the incisure shallow, the outer and 

 inner margins slightly rounded, membrane with a single cell not 

 reaching beyond apex of cuneus, inner apex of cell subobtusely an- 

 gidar. Vagina of female passing middle of abdomen. Legs slen- 

 der; fore coxae not reaching middle of mesosternum; all femora 

 linear, the hind pair a little thicker than the others; tibiae spar- 

 ingly, shortly, and softly pilose, not spinulose; third joint of tarsi 

 incrassated toward apex, claws small, strongly curved, arolia shortly 

 laminate. 



This genus must be referred to the subfamily Bryocorinae, from 

 all other genera of which it differs by the horizontally produced 

 head. The membrane appears to be bicellulate, there being a vein 

 separating a narrow elongate outer cell from the other, but unless I 

 am mistaken it is the anal vein of the underlying membrane which 

 is visible through the translucent upper membrane.

IX PORRECTA, new species. 



Subglabrous, shining, beneath more so; above castaneous, cuneus, 

 and a costal spot immediately before it red, beneath piceous (except 

 the pale castaneous throat) ; membrane pellucid, a little shaded with 

 brownish gray, iridescent, its veins piceous; antennae, rostrum, and 

 legs pale yellowish testaceous, first joint of antennae pitchy casta-
