Holotype male from Chaco, Bogota, Colombia, August 11, 1940 (L. Richter) 
on indefinite loan to USNM from NCS. Additional specimens have been seen 
from ‘‘Bucaramanga”’ and “‘Carare”’, Colombia and with labels merely ‘‘Colom- 
bia”’. 
Agrosoma iluha, n. sp., is closely related to A. cruciata (Signoret) from which it 
can be distinguished by the aedeagal characters mentioned above. It is also 
closely related to A. nabima, n. sp., from which it can be distinguished by the 
aedeagal characters mentioned in the following description and by the black 
posterior border of the pronotum in nabima. 
Agrosoma nabima, NEW SPECIES 
FicureE 12 
Length 8.1-8.7 mm. Head with median length one-third or less transocular 
width. Forewing with veins indistinct. Male pygofer with process much as in A. 
cruciata (Signoret), in the form of an inverted “‘V” in lateral view, but with apex 
extending beyond pygofer margin; aedeagus as in A. tluha, n. sp., but with more 
apical pair of processes greatly reduced and located laterally on shaft and with 
more ventral pair of processes rounded dorsally but longer and more narrowed 
anteapically than specimens of 1/uha which have processes so rounded; preatrium 
as in tluha. Other structural characters as in generic description. 
Color of head and pronotum much as in z/uha but with posterior margin of 
pronotum fairly broadly bordered with black throughout its extent. Forewing 
with pattern variable, the hindmost red area often completely encircled in white, 
the diameter of the circle being greater than shown in any of Medler’s (1960) 
illustrations. 
Holotype male, Balzapamba, Ecuador, 700 m., 28 May, 1938 (W. Clark- 
Macintyre) on indefinite loan to UNSM from NCS. Additional specimens from 
Cojimies, Manabi; Pucay Uacu, Los Rios; Santo Domingo; road between Quito 
and Santo Domingo; nr. Riobamba, Chimborazo; Linje, Bafios, and Chimbo, all 
in Ecuador. 
A. nabima, n. sp., is closely related to A. iluha, n. sp., and to A. cruciata 
(Signoret). It differs in that the pygofer process extends beyond the pygofer 
margin in lateral view, in the characters of the aedeagus mentioned in the above 
description and in the black band across the hind pronotal margin. 
6. TAHUAMPA, NEw GENUS 
Ficures 13, 14 
Type-species: Tettigonia septemfasciata Signoret. 
Length 11.5-12.5 mm. 
Head moderately produced, median length of crown approximately one-half 
interocular width and approximately one-third transocular width, anterior 
margin broadly rounded in dorsal view, without a carina at transition from 
crown to face, ocelli located behind a line between anterior eye angles, each 
approximately equidistant from latter and median line, crown convex, without a
