Carrikerella ceratophora new species (Plate IX, figures 24, 25, and 26.) 
Though having the altdoiiiinal appendages less decidedly and 
remarkably specialized than in the species of Pogonogaster, this 
insect, showing a similarh^ juvenile-appearing facies, is very 
remarkable in the bifid horn, developed on the head above the 
ocelli. 
The apparently fully formed genitalia in the female at hand 
cause us to believe that the adult condition is represented. 
Type . — 9; Andagoya, Antioquia, Colombia. April 22, 1918. 
(INI. A. Carriker, Jr.) [Hebard Collection, Type no. 738.] 
In addition to the characters discussed in the generic diagnosis, we note 
the following for this species. Size comparatively small, form slender, ab- 
domen somewhat enlarged. Antennae very short, exceeding slightly in 
length the horn above the ocelli. Triangle formed by ocelli three times as 
broad as deej). Pronotum with dorsal surface smooth, but develojied as 
described; supra-coxal expansion less i)roduced than in either of the known 
species of Pogonogaster. Foliaceous meso-caudal plate of second tergite 
largest, that of first tergite next in size, of third tergite next, and of median 
segment smallest of these. 
CJeneral coloration clay color; pronotum with a few weak suffusions of 
sepia, the heavier of the marginal spines, which are widely spaced, sepia; 
abdomen dorsad with numerous microscopic weak flecks and dashes of 
sepia, the foliaceous meso-caudal and latero-caudal plates light yellowish olive, 
the lateral margins of the abdomen and margins of these plates (except the 
caudal margins of the latero-caiulal plates) with minute flecks of sepia. Ceph- 
alic coxae huffy with a greenish tinge, with two vague suffusions of tawny 
olive. Cephalic femora warm buff’ with four suffused annuli of sayal brown, 
the two median of which deepen to snuff brown at the dorsal margin. Caudal 
tibiae and tarsi warm buff, the latter with distal joints and apices of proximal 
joints sepia. Median and caudal limbs huffy with a greenish tinge, flecked 
and obscurely annulate with bister. The tinge of green shown in the folia- 
ceous jilates and limbs may indicate that this specimen, in life, was of a much 
more greenish coloration. 
Length of body, 28; length of cephalic cone, 1.5; length of pronotum, 
9.8; wi(.lth of i)ronotum at supra-coxal expansion, 2.7; length of pronotal 
shaft, 6.9-; width of pronotum at narrowest portion of shaft, 1.2; length of 
process of median segment, .9; width of process of median segment, .6; 
length of process of second tergite, 1.3; width of process of second tergite, .8; 
length of supra-anal plate, 1.4; length of cephalic coxa, 7; length of cephalic 
femur, 8.3; width of cephalic femur, .9; length of cephalic tibia, 2.8; 
length of caudal femur, 7.1; length of caudal tibia, 8.2; length of caudal 
metatarsus, 4.3 mm. 
The type of this remarkable mantid is unique.
