the pronotum which is set in a depression, and have hairy eyes; thus 
they key out readily in my key. In these males LFW is 2. 1-2.6 mm; 
WH is 1. 02-1. 05 X LH, 1 .25-1.30 X HE, OOL about 1.5 X 
WOT. There are no important differences in color or sculpturing 
as compared to the female except that the front is only obscurely 
punctate and the antennal scrobes are carinate (as is usual in males 
of this genus). 
Bakeriella rossi Evans, 1964 
The collecting of Schlinger and Ross in the Monson Valley, l ingo 
Maria, Peru, in September and October 1954 also turned up 1 $ 
and 3 cf cf of this species, previously known from 3 cf cf from Co- 
lombia. The female will run to couplet 8 of my key; the 5-toothed 
mandibles at once separate it from brasiliana , the very weakly arched, 
non-angulate transverse pronotal carina from olmeca , the fuscous 
coxae and femora and much larger size from floridana. The female 
is 5.5 mm long, LFW 3.9 mm; the body is black except that the 
apical fourth of the abdomen is suffused with dull ferruginous. The 
clypeus is sharply, obtusely angular; the eyes are hairy; the vertex is 
broadly rounded off far above the eye tops, WH being only .9 X 
LH; WF is 1.22 X HE, OOL 1.8 X WOT, the propodeal disc 
1.2 X as wide as long and bearing the usual three carinae. 
Bakeriella depressa Kieffer 
Since treating this species in 1964, I have seen one additional male, 
from Tena, Ecuador, collected February 28, 1923, by F. X. Williams 
[Bishop Mus., Honolulu], It is the largest specimen I have seen 
(LFW 3.0 mm) but presents no unusual structural features. The 
antennae of this species are consistently more elongate than in flavi- 
cornis Kieffer, segments three and eleven being 1.35- 1.5 X as long as 
thick as compared to 1.1-1.3 X as long as thick in flavicornis. Also, 
the antennae of most specimens are decidedly dusky apically, while in 
flavicornis they are wholly light yellowish brown. In addition to the 
type of the latter species I have seen four topotypic paratypes in the 
collection of Cornell University. 
Calyozina mexicana n. sp. 
This remarkable species seems to be closer to the type species, 
ramicornis Enderlein, from Formosa, than to the two neotropical 
species I assigned here in 1964. In particular, there are ten long 
branches on the antennae as opposed to only seven or eight short
