SUBFAMILY II. — MEZIRIN^E. 319 



pression slightly behind middle, front angles more prominent 

 than hind ones, often ending in obtuse spines ; membrane of 

 nearly the same texture as corium, the veins of both vague or 

 wanting; sides of abdomen not dilated or lobed ; posterior api- 

 cal angle of sixth dorsal prolonged. Five species are known, 

 all southern in distribution, two of which occur in Florida. 



KEY TO EASTERN SPECIES OF PROXIUS. 



a. Third antennal one-half longer than second; middle of scutellum 



with a T-shaped elevation. 250. gypsatus. 



««. Third antennal twice as long as second; middle of scutellum with a 



reversed T-like elevation. 251. schwarzii. 



250 (399). Proxius gypsatus Bergroth, 1898, 100. 



Elongate, subparallel. Reddish-brown, above thickly coated with a 

 clay-yellow crust; corium dull white; membrane and apical angles of 

 connexivals tinged with fuscous ; antennae and legs reddish-brown. Ver- 

 tex of head with sides dilated and projected outward beyond eyes, the 

 callosities forming an elongate triangular plate on middle of head. Joints 

 3 and 4 of antenna? subequal in length. Pronotum as under generic head- 

 ing, the incrustation forming a large bifid elevation on front half of 

 disk, four small obtuse tubercles along its basal margin, a ridge along 

 each side margin and a conical tubercle on each front angle. Scutellum 

 with median ridge as in key, the sides also thickened. Length, 3.5 — 

 4.5 mm. 



St. Augustine, Fla. (U. S. N. Mus.) . The types of Bergroth 

 were from "Florida," and Venezuela. Known elsewhere only 

 from Guatemala and Panama. 



251 (400). Proxius schwarzii Heidemann, 1904, 230. 



Elongate-oval. Reddish-brown covered in some places with a yel- 

 lowish-white incrustation; legs light brown, femora 

 darker towards tip. Head about as long as broad, 

 in its middle a longitudinal ridge with a large hole 

 at its broader end, each side of ridge with a long 

 deep excavation ; tylus much shorter than apical 

 lobes of head ; antenniferous processes strongly 

 spined and curving inwardly, reaching middle of 

 first antennal. Joint 1 of antenna? stout, slightly 

 surpassing apical lobes of head, 2 oval, shorter 

 than 1 ; 3 very thin, about twice as long as 2, 4 

 nearly as stout and long as 1. Pronotum and scu- 

 tellum with encrusted ridges as in key and fig. 66. 

 Abdomen one-third longer than broad, narrower 

 at base than before the apex, last segment with 

 Fig. 66, female, x io. sides deeply sinuate, the posterior apical angle 

 (After Heidemann). acute> Len gth, 4.5 mm. (Fig. 66).
