SUBFAMILY III. — DUFOURIELLIN^. 641 



II. Physopleurella Reuter, 1884, 124. 



Elongate-oblong pubescent species having the head distinct- 

 ly longer than the width across eyes, the projecting tylus 

 shorter and narrower than interocular width ; eyes prominent, 

 occupying the full thickness of the head ; pronotum with hind 

 margin deeply and widely sinuate or concave, disk with pre- 

 apical transverse impression fine but evident ; median trans- 

 verse impression ill defined, the area in front of it with callus 

 but little elevated, and with a short posterior longitudinal 

 median groove, hind portion depressed at middle; elytra en- 

 tire, the membrane 4-veined, the three outer ones with bases 

 remote and equidistant one from the other, the inner one with 

 base forked, enclosing a small triangle ; osteolar channel sur- 

 passing middle of metasternal plate, its apical portion curved 

 backward ; front femora in our species more evidently swollen 

 than the others, with the lower inner margin beset with nu- 

 merous fine setae ; front tibiae distinctly curved ; mesopleura 

 strongly rugose. 



This genus was founded by Reuter for a single species, the 

 Cardiastethus mundulus White, from Hawaii. Specimens from 

 Florida agree in all respects with the generic characters as 

 given by Reuter, except that the pubescence is mostly very 

 short, the side margins of pronotum and embolium not ciliate 

 with long hairs and the front femora are setose beneath. 



618 ( — ) . Physopleurella floridana Blatchley, 1925, 47. 



Elongate-oblong, subparallel. Head, front lobe of pronotum, scu- 

 tellum and under surface pale to dark reddish-brown, strongly shining; 

 hind lobe of pronotum with the basal margin and humeral angles fus- 

 cous-brown ; elytra, except membrane, dull straw-yellow with cuneus and 

 a more or less evident cross-bar across the apical third of clavus and 

 corium fuscous; membrane whitish-hyaline, the basal half tinged with 

 dusky; antenna?, beak and legs pale brownish-yellow. Joint 1 of antennae 

 slightly surpassing the truncate tip of tylus, 2 linear, about as long as 

 bead, 3 and 4 more slender, subequal, together slightly longer than 2. 

 Pronotum as described above, its sides obtusely margined, the deeply 

 concave hind margin with a fringe of yellowish hairs ; disk with a short 

 ridge each side of middle connecting the two lobes, the hind lobe de- 

 pressed and punctate at middle, its humeral angles broad, obtusely 

 rounded. Scutellum with basal portion less elevated than usual, apical 

 portion flattened, with a bilobed fovea at base, apex acute. Elytra but 

 slightly sm-passing abdomen, clavus finely iri-egularly punctate, corium 

 and embolium very minutely punctate, all the punctures each bearing a 

 short fine appressed hair. Genital plate of male transverse, its hind 

 margin broadly rounded. Length 2.8 — 3 mm.
