[June 
interocular i. 00-1.05 times lower. POL:OOL about as 4:3. Third 
antennal segment 1 .4-1.6 times as long as thick. Subgenital plate 
with a strong median keel; genitalia differing from those of bergi 
only in having more heavily setose parameres, a more deeply cleft 
aedoeagus, and slightly longer and broader parapenial lobes (Fig. 2). 
Distribution. — Central Chile, Patagonia. 
Specimens examined. — 4 $$, 2 c?cf. chile: i $, 1 c?, Marga

lotype, MCZ ]; 1 1 cf , Valle los Piuquenes, Rio Blanco, Prov. 
Aconcagua, Feb. 7-12, 1964 (L. Pena) [MCZ]; 1 $, Pichinahuel,

berg) [USNM], 
Remarks. — The close similarity of the male genitalia of jaffueli 
and bergi indicates conclusively that the presence or absence of rugae 
on the female propodeum should not be regarded as a generic char- 
acter. The description and drawing of the genitalia of jaffueli were 
made from the specimen from Valle los Piuquenes. The genitalia of 
the allotype we-re extracted some years ago by R. R. Dreisbach, but 
the slide which he prepared contains only a broken fragment of the 
subgenital plate, the genitalia presumably having been lost.
