22 segments; segment I longer than broad; segment II shorter than 
I and with axis slightly outcurved; segment III slightly longer than 
II and broadest near distal margin. Antenna with setae on the 
more distal segments partly arranged in two or three transverse 
rows. Distal tooth of mandible much larger than the other three, 
which graduate in length, the most nearly medial being the smallest. 
Outer lamina of inner lobe of maxilla not pectinate, slender and 
curved, the other laminae pectinate. 
Pronotum well supplied with setae of varying lengths. Mesonotum 
divided near its anterior end by a curved transverse suture in front 
of which are five setae, two being large and robust; the remainder 
of the mesonotum and the metanotum richly beset with setae of vary- 
ing lengths. Tarsi each terminated by two subequal lateral claws 
and a vestigial median claw. 
Abdomen with first six terga subequal; each with a transverse 
line near its anterior end, in front of which are a variable number of 
small setae. Sterna richly provided with small setae. Subcoxal or- 
gans of segment I each bearing a row of five subequal long setae and 
a number of hairlike microsetae. Styli similar, subequal, each with a 
subbasal small seta. Segment VII not so broad as VI, much more 
heavily sclerotized but with fewer setae. Segment VIII narrower 
than VII, more than twice as long as [X. Chaetotaxy of segment X 
and chaetotaxy and dental armature of forceps as shown in plate 33, 
figure 1. 
Length of body, including forceps, 7.0 mm.; width (that of segment 
III of abdomen), 0.6 mm. 
Type locality —San José de Pinula, Guatemala. 
Type (holotype) —U.S.N.M. No. 552138. 
Remarks.—Description based on a single adult specimen taken at 
the type locality in May 1924 by Wm. M. Mann. 
This species is similar to £. bruneri Silvestri but may be readily 
separated from it by the dental armature of the forceps and by the 
number of antennal segments.

PLATE 33, FicuRrE 3 
Description—Head with lateral margins almost straight for most 
of their length but strongly curved near base. Antenna long, num- 
ber of segments 32; segment I longer than broad; segment II shorter 
than I and with axis slightly outcurved; segment III about as long 
as II and broadest near distal margin. All antennal segments well 
clothed with hairlike setae, those on the more distal segments ar- 
ranged in several irregular rows. Distal tooth of mandible much 
larger than the other three; two proximal teeth united at base and
