NO. 2150. SOME NEW HETEROPTEROUS HEMIPTERA—BERGROTH. 221 



each side somewhat within the lateral margin with a rather large 

 transverse dull impunctate impression, that of the fifth segment sit- 

 uated at the apical margin, that of the sixth segment less distinct 

 and placed at the basal margin. The sixth ventral segment of the 

 male is in the middle distinctly longer than the two preceding seg- 

 ments together, that of the female slightly shorter than these. The 

 male genital segment is as long as the sixth ventral segment, trans- 

 versely impressed before the apical margin, which is rounded, in the 

 middle slightly sinuate and thickly fringed with pale ferruginous 

 hairs. The basal lobes of the female genital segment are about as 

 long as broad, rounded exteriorly and a little narrower there than 

 interiorly ; the median lobes are narrow, transverse ; the apical lobes 

 transverse, separated interiorly by a triangular incision. After 

 death the olivaceous green color of the upper side of the body some- 

 times fades into pale brownish. The black spots of the connexivum 

 occupy more than the apical half of the segments. 



Patagonia (Chubut). 



Numerous specimens of both sexes have been examined. 



This genus is not " to be placed near Hellica Stal," with which it 

 has no resemblance, but is allied to Sinopla Signoret. 



ACROPHYMA,* new genus. 



Body oval. Head shorter than pronotum, rather strongly nar- 

 rowing from the eyes to the apex, anteocular part broader than long, 

 lateral margins slightly sinuate, clypeus gradually widening from 

 base to apex, juga as long as clypeus, ocelli over two times more dis- 

 tant from each other than from eyes; bucculae low, not reaching 

 base of head; rostrum reaching hind coxae, first joint as long as 

 bucculae, second longer than third; first joint of antennae much 

 shorter than head, but passing its apex; second joint longer than 

 first and third. Pronotum moderately declivous, apical margin 

 sinuate, obliquely truncate behind eyes, apical angles narrowly 

 rounded, lateral margins slightly rounded, not elevated, lateral 

 angles rounded, not prominent, basal angles very obtuse, basal mar- 

 gin straight. Scutellum equilaterally triangular, not reaching mid- 

 dle of abdomen, with a small callose spot at basal angles, apex sub- 

 acute and very shortly spatulate. Mesosternum with a median 

 carina. Orificia extended in a straight parallel sulcated fold, which 

 is half as long as the distance between its tip and the lateral margin 

 of the metapleura. Corium with rounded costal margin and 

 straight apical margin ; membrane with five simple veins, the three 

 median ones united not far from the base by an oblique cross-vein, 

 forming two median basal cells. Abdomen scarcely broader than 



> aKpos=acute; vi;Ma= tubercle.
