Evans — Epyrini 
mandibles and at least some evidence of a median carina on the prono- 
tum. 
Bakeriella subcarinata n. sp. 
This is the fourth known species in which the male possesses a 
vertical carina on the temples and a median carina on the pronotum ; 
it is the second of these four species in which the female is known (or 
at least tentatively associated with the male) . In this case the female 
lacks a carina on the temples (as in olmeca Evans) but possesses a 
weak median carina on the pronotum (in contrast to olmeca). The 
female will run to inca Evans in my 1964 key, but it differs in 
several respects, most conspicuously in having 5-toothed mandibles and 
in having the median pronotal carina very weak and not set in a 
depression. The male runs to olmeca in my key, but differs in having 
well formed lateral ridges on the pronotum and in having the third 
antennal segment only 1.3 X as long as thick. 
Allotype. — PERU: Quincemil, Dept. Cuzco, 750 meters, Nov. 
5-16, 1962 (L. Pena) [MCZ]. 
Description of female allotype. — Length 5.0 mm; LFW 4.3 mm. 
Black; mandibles testaceous except black at base, the teeth rufous; 
antenna pale ferruginous, scape and outer flagellar segments strongly 
infuscated on upper surface; legs black except tibiae and tarsi dull 
ferruginous; wings lightly tinged with yellowish brown. Mandibles 
with a broad, oblique apical margin which bears five teeth, the basal 
three teeth very much smaller than the two large apical teeth. Clypeus 
very short, broadly subangulate. Eyes weakly hairy; antennal scrobes 
not margined; third antennal segment about 1.5 X as long as thick. 
WH .95 X LH ; eyes converging below, WF 1.20 X HE; OOL 
1.5 X WOT. Vertex broadly rounded off a considerable distance 
above eye tops; temples fairly broad but ecarinate. Front shining, 
weakly alutaceous, with strong punctures which are separated by 
1-3 X their own diameters. Pronotal disc somewhat more strongly 
alutaceous, also with strong punctures; anterior, transverse carina 
straight; median carina weak, alutaceous, not set in a depression; 
posterior margin with a polished ridge; sides of disc subcarinate in 
front; side-pieces rugose, especially below. Mesoscutum polished 
anteriorly, posterior half alutaceous, punctate, slightly depressed ; 
scutellar pits large, transverse, separated by a thin septum. Propodeal 
disc 1. 1 5 X as wide as long, transversely striate between the three 
discal carinae, otherwise with only weak sculpturing. Front femora 
measuring 2.4 X as long as wide.
