waxy secretion oil each side in the constriction, giving the appearance 
of a transverse band. Head with vertex deeply impressed, post-an- 
tennal ridges well developed and sharply defined, the antennal fossae 
deeper and separated by a sharp carina; clypeus tumid but not swol- 
len ; more distinctly indexed than in bor gmeieri ; surface very coarsely, 
densely, and deeply punctate. Antennae about 2.50 times as long as 
pronotum; segment I 1.33 times as long as wide, subglobular. Prono- 
tum 0.76 times as long as wide at base, anterior angles strongly 
produced, the sharp flanges distinctly longer than the medio-lateral 
tubercles, which are sharp and conical, the other medial tubercles 
higher and sharper than in borgmeieri , 2 comma-shaped antero-mesal 
longitudinal ridges bordering a median impression which extends 
to anterior edge; surface very coarsely and densely punctate, as is 
scutellum, and clothed with yellowish bristles, which are finer and 
longer than those on elytra. Elytra 1.93 times as long as wide at 
base and 3.77 times as long as pronotum; base with humeral cal- 
losities strongly developed and somewhat carinate, without antero- 
mesal elevations, but with a deep puncture on either side of the 
suture; dorsal striae distinct for their entire lengths, lateral striae 
8 in number, containing glandular pores as in borgmeieri which are 
also concentrated in the constriction ; elytral apices only slightly diver- 
gent and rounded. Hind legs as in borgmeieri , but lacking a pencil 
of black hairs on the tibia. Abdomen of male with a distinct median 
impression on the first two visible sternites. Aedeagus (of paratype) 
elongate, basal piece subquadrate, subangulate basally, tegmen deeply 
cleft apically forming 2 fairly narrow and straight lateral lobes or 
parameres which are expanded and setose at their tips; median lobe 
narrow and elongate, curved dorsally at apex and at base, where it 
is attached to base of tegmen (Figs. 10 — 12). Total length: 3.17 — 
3.30 mm. (type 3.17 mm.) ; greatest width (across humeral cal- 
losities) : 1.27 — 1.38 mm. (type 1.27 mm.).

Fabrasia wheeleri is easily distinguished from the other two species 
by its larger size, sharper pronotal tubercles, different clypeal struc- 
ture, shorter pubescence, and the absence of pencils of hairs on the 
hind tibia. It certainly seems to be more distantly related to either 
alvarengai or borgmeieri than these two are to each other. The
