type data: “. . . i holotipo de Brasil, Rio Grande do Norte, 
Natal, VI-1951 (M. Alvarenga-leg.) , en la coleccion Moacir Al-

represented by a single specimen whose abdomen is missing so that the 
determination of sex is impossible. 
Fabrasia borgmeieri, new species 
(Figs. 6 — 7) 
description : Reddish-brown with dark brown spots on elytra ; 
clothed with short yellowish bristles, which are longer on elytra and 
more concentrated in median constriction, giving the appearance of 
a transverse band on each side. Plead with vertex shallowly im- 
pressed, post-antennal ridges weakly developed, antennal fossae rel- 
atively shallow and separated by a weak, somewhat flattened ridge; 
clypeus tumid, but not swollen as in alvarengai ; surface coarsely, 
densely and shallowly punctate and granulate. Antennae almost 3 
times as long as pronotum; segment I 1.57 times as long as wide, 
expanded at apex. Pronotum 0.79 times as long as wide at base, an- 
terior angles moderately produced, the sharp flanges only slightly 
longer than medio-lateral tubercles, which are sharp and conical, 
the other discal tubercles low and rounded; surface rugosely punctate 
and granulate, as is scutellum, and clothed with short yellowish 
bristles. Elytra 1.94 times as long as wide at base and 3.81 times 
as long as pronotum ; base with large and rounded humeral callosities 
and a low rounded elevation on each side between callosity and 
suture; dorsal striae obsolete except at base, lateral striae 6 in num- 
ber, very deep in the vicinity of the medial constriction, where the 
glandular pores are larger and closer together; elytral apices strongly 
divergent and narrowed, forming 2 triangular processes; surface 
smooth and shiny, clothed with suberect yellowish bristles, which 
form brushes laterally in between the pores. Hind legs as in alvar- 
engai, but the tibia with a longer pencil of black hairs on outer side 
and a shorter one on inner side. Abdomen strongly convex anteriorly, 
but not impressed mesiaily. Total length: 2.87 mm.; greatest width 
(across humeral callosities) : 1.12 mm. 
type data: Holotype, probably 9, Campinas, Goias, Brazil, ii.1964, 
Schwarzmaier col., with Gamponotus ( Myrmothrix) renggeri Emery 
(T. Borgmeier, det.). Holotype deposited in the Departamento de
