NEW JAPYGIDAE—EWING AND FOX 293 
together forming a broad curved tooth. Outer lamina of inner lobe 
of maxilla not pectinate, long and slender, 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 is a single pair of setae, the remainder of the mesonotum 
and the metanotum richly beset with setae of varying lengths. Tarsi 
each terminated by two subequal lateral claws and a vestigial median 
claw. 
Abdomen with first six terga and sterna essentially as in the pre- 
viously described species. Subcoxal organs of segment I each with 
a row of about 30 setae. Abdominal segments VII, VIII, and IX 
as in the previously described species. Chaetotaxy of segment X and 
chaetotaxy and dental armature of forceps as shown in figure 3. 
Length of body, including forceps, about 11 mm.; width (that of 
segment III of abdomen), 1.3 mm. 
Type locality —KEstrella Valley, Costa Rica. 
Type (holotype) —U.S.N.M. No. 55214. 
Remarks.—Description based on a single adult taken at type locality, 
April 1924, by Wm. M. Mann. 
This species superficially resembles #. crassicauda Silvestri, from 
which it may be readily distinguished by the dental armature of the 
forceps. 
CATAJAPYX NEOTROPICALIS, new species 
PLATE 33, Ficure 2 
Description.—Head with lateral margins strongly curved. An- 
tenna consisting of 80 segments; segment I broader than long; seg- 
| ment II longer than I and strongly outcurved; segment III about as 
long as IT and broadest near distal margin. Setae of antenna on the 
more distal segments partially arranged in one or two rows per 
segment. Mandible possessing five teeth, the distal larger than the 
others, the proximal smallest and broadest, almost triangular. Outer 
lamina of inner lobe of maxilla not pectinate but armed distally with 
two to several processes, other laminae pectinate. 
Pronotum with a well-developed median apodeme and well sup- 
plied with setae of varying lengths. Mesonota and metanota also 
richly provided with setae. Tarsi each terminated by two unequal 
lateral claws and a small, slender, acuminate, weakly sclerotized, 
median claw. 
Abdominal terga I through VI subequal, well supplied with setae, 
abdominal segment VII wider than VI and more heavily sclerotized; 
segment VIII not so broad as VII, less than twice as long as IX. 
Abdominal sternum I with a broad area of what seem to be sense 
setae on each side. Subcoxal organ not sufficiently distinct in the
