are ferruginous brown with a yellow line on the femora beneath 
and on the coxae. 
The celypeus is moderately convex, depressed slightly at the 
apex and broadly emarginate, the angles of the emargination not 
much produced. The hypopygium is very narrow, produced a little 
beyond the dorsal segment and narrowly rounded at the apex, the 
sides parallel. Median segment much broader than long. The 
maxillary palpi are short, the five apical joints of almost equal 
length. The interantennal prominence is broad, bilobed, the lobes 
vounded at the apex; the scape is ferruginous brown. Length 13 mm. 
This is probably merely a slight colour variety or perhaps a 
local race, of Gu£rın’s species, but I have not seen the type or 
any specimen from the same locality, and Gu£rın does not give 
many details as to structure. It belongs to the group represented 
by maculipennis Gukr. which is very closely connected with the 
lateralis group, and is not very near typical Elaphroptera.

2. The elypeus is somewhat more convex than in the specimen 
trom Paraguay, subtuberculate in the middle with a tuft of long 
hairs. The apex of the seventh dorsal abdominal segment is 
shallowly emarginate, not truncate as in the Paraguay specimen. 
Length 17 mm.

2. Clypeus sliehtly produced, broadly emarginate and feebly 
porrect at the apex, the angles of the emargination not produced 
into -spines, slightly concave before the apex and punctured. 
Mandibles strongly longitudinally rugose from the base to the base 
of the teeth, bidentate, the inner tooth much shorter than the outer 
and broadly truncate. Antennae rather shorter than the head, 
thorax and median segment combined, the apical joints arcuate, 
inserted rather nearer to each other than to the eyes, the frontal 
prominence between them transverse, not bilobed, a very delicate 
longitudinal carina on the front not quite reaching the anterior 
ocellus. Head, thorax and median segment closely punctured, rather 
thinly clothed with long black pubescence; the pronotum a little
