is not complete, the chitinous margins being connecteil by soft integument. 
Subgenital plate ample, scoop-sha])e(l, not strongly ])roduced, free margins 
convex, except at bases of cerci, where moderate emargination is found. 
Coloration generally similar in the sexes. Antimony yellow, in the female 
showing a slightly more ochraceous tinge. Disk of jjronotum with a very 
weakly defined pair of slightly darker median flecks. Tegmina nearly trans- 
parent, with veins and numerous transverse veinlets jiale buffy, the inter- 
vening minute areas tinged with the general coloration; so that the tegmina, 
under high magnification, are seen to be delicately and minutely tessellate. 
Wings transparent, very faintly tinged with huffy, this very slightly stronger 
in area of costal veins. The deejiest coloration is on the dorsal surface of the 
abdomen, which is antimony yellow, washed with ochraceous orange. 
Length of body, d' 12, 9 13. .7; length of pronotum, d 3.3. 9 3; width 
of pronotum, d 3.S, Q o.A; length of tegmen, d 13.7, 9 lo.2; greatest

In addition to* the descrii)ed pair, a female, in the la.st instar 
preceding maturity, bearing the same data, is before us.

This immature example would appear to represent the present 
species, described from the same locality. Until the type is analyz- 
ed or more material is seen from that region, the exact posi- 
tion of albida remains in doubt. 
Neoblattella antioquiae new species (Plate VIII, figure S.) 
The present insect is a member of the Impar Group of the 
genus. It is apparently closely related to Ab albida (Saussure), 
differing in features of coloration, but particularly in the very 
high and intricate specialization of the male subgenital plate. 
As in albida, the distal cross-veinlets of the tegmina are strik- 
ingly darkened. 
Type. — (T , Andagoya, Antioquia, Colomltia. April 22, 1918. 
(M. A. Carriker, Jr.) [Hebard Collection, Type no. 543.] 
Size large Gr the Impar Group, form rather slender. Interocular si)ace 
four-fifths as wide as that between the antennal sockets, ocellar spots weakly 
defined. Maxillary palpi very elongate, fifth joint three times as long as 
greatest width, three-quarters as long as fourth joint, which is slightly shorter 
than the very slender third joint. Pronotum as in N. acanthasiylata Hebard, 
as characteristic of the Impar Group.
