strongly convergent; lateral borders of hindlobe parallel, rounded and 

 convergent anteriorly. Hindborder sinuate medially. Foredisc with 

 four (2+2) large, flat callosities. Hind-disc finely, transversely 

 rugose; with two (1 + 1) large, transverse, elongate, glabrous spots 

 mesad of humeri. 



Scutellum short, wide at base (12:21), widely rounded apically; 

 disc concentrically rugose. 



Hemelytra almost reaching hindborder of tergum VII. Corium 

 very short, reaching middle of scutellum. Membrane large, finely 

 wrinkled. 



Abdomen ovate, longer than width across segment IV (52:39). 

 Outer borders of connexiva with semiobliterated granidation; hind- 

 borders of connexival segments glabrous, shiny. Spiracles II lateral 

 and visible from above; III to V sublateral, but not visible from above; 

 VI and VII lateral and visible; VIII tenninal. Paratergites small, 

 strongly divergent, not reaching tip of hypopygium. Latter small, 

 lateral borders convergent; tip rounded; disc moderately convex. 



Femora moderately inflated, fusiform. 



Color. ^ — Dark brown; hindhalf of head, middle of pronotum, and 

 base of scutelliun, yellow broA\Ti; membrane black. 



Measurements. — Total length 3.84 mm.; width of pronotum 1.2 

 mm.; width of adbomen 1.56 mm. 



HoLOTYPE. — Male, Guadeloupe; deposited in Drake collection 

 (USNM type 67584). 



Aneurus nasutus, new species, is not particularly related to any of 

 Central American species; it appears to be most like A. subdipterous 

 Burmeister from southeastern Brazil, but is smaller. Antennae are 

 similar to those of A. tenuis Champion but the shape of the head is 

 quite different: antenniferous and postocular tubercles small, and 

 blunt; scutellum of different shape; lateral borders of the pronotum 

 and abdomen are smoother, not finely crenulate; hypopygium is 

 larger; and color is different. 



Subfamily Carventinae Usinger, 1950 



Usinger (1950, p. 176) divided the Mezirinae into two tribes, 

 Mezirini and Carventini. Later, Usinger and Matsuda (1959a, p. 56) 

 elevated the latter to a subfamilial rank. All members of the Car- 

 ventinae are tropical or subtropical, none occur in the holarctic 

 region. Many of them are apterous or micropterous. The ivory-like 

 incrustation on the body of some species, as in the genus Proxius, 

 may accumulate on tufts of hair and produce projections which give 

 the insect a bizarre appearance.
