HEPTAPSOGASTER MANDIBULARIS IDONEUS, new subspecies 
FIGURE 18} c-f 
Types.—Male and female, adults, from Crypturellus idoneus, col- 
lected by the author at El Bosque, Sierra Perija, Colombia, June 14, 
1941; in U. S. National Museum. 
Diane = Wa is a well-defined race, represented in the collection 
by a large series of both sexes. The Suave of the head somewhat 
resembles that of H. m. garleppi, with long, widely divergent temples 
and nearly straight (slightly convex) sides. It differs from garleppi 
in the narrower, more convex front, larger trabecular tubercles, shape 
of the depression at inner side of antennal fossae, and in having sides 
of temples uniformly, though but shghtly, convex, while in garleppi 
they are stratght, but undulating. 
The head in une female is also much larger than that of garleppi, 
with more flattened frons, larger trabecular tubercles, more convex 
temples, which are much infec at their tips (see figure). The last 
abdominal segment in the female is similar in shape to garleppz, but 
the genital sclerites have almost straight, parallel sides, and the 
anterior end is ¢runcate. 
The male genitalia rather resemble those of yapurae in size and shape 
of paramers, but the basal plate is narrower. The endomeral plate 
is longer and more deeply inserted within the basal plate, while 
the endomeral prongs are much longer and thicker amd have a trans- 
verse, chitinized plate across their bases, instead of internal, crescent- 
shaped struts. The scent gland is long and narrowly crescent shaped, 
as in nigriceps. 
Remarks.—This race has the head with many features resembling 
modestae (from C. b. boucardi of Mexico), but the genital armature is 
quite different and apparently unique among the races of mandibularis.
