laticinctus. P. laticinctus Hmps.(= fasciolatus Druce) (10 e). The body is. yellow; the palpi are black-banded, 
the forehead is whitish with a black band between the antennae; collar, shoulder-covers and thorax striped 
in black. The first abdominal ring is black-striped in the middle and on the lateral tubercles; the other segments 
exhibit black transverse bands. The hyaline wings are darkened by yellow-brownish in the costal-marginal 
half down as far as the middle radial. The species flies in Guatemala. 
decepfans. P. deceptans Zerny (10 e) differs from laticinctus to which it is very closely allied, by unicolorously 
lemon-coloured palpi and forehead and the much narrower, yellow hindmarginal bands of the abdominal segments, 
and at the collar the fore- and hindmargins are yellow. -— Described from Brazil (Blumenau in Sa. Catharina); 
a specimen undoubtedly belonging hereto is before me from Colombia (Muzo), from the Coll. Fassl. 
ichneu- P. ichneumoneus H.-Schdfj. (= polybioides Burm.) (10 e) one of the most ichneumon-like species 
moneus. w jf |, a black, somewhat purple-lustrous abdomen. The antennae are brownish or black with a purple reflection. 
The yellow-brownish hyaline wings, being somewhat opalescent, have brown veins. -— In the typical form 
crabronis. the wings are for the most part covered with black-brown hair-scales which are absent in ab. crabronis or only 
quite faintly indicated in a light brownish; the latter form seems to be more common. From Central America 
through Brazil to Paraguay, Uruguay and Argentina. 
lnjalozonus. P, hyalozonus Fldr. (10 d) resembles the following species by its size, but it is immediately recognizable 
by quite black palpi and more intensely blue-lustrous forewings with a hyaline inner margin. The forehead is 
grey, the abdomen beneath at the first segment spotted in whitish, both the first segments below narrowly 
margined in white. The hindwings are hyaline with fine black veins and margin, and the costal marginJs dusted 
in dark brownish-grey. Colombia (Bogota). 
rubripalpus. P. rubripalpus limps. (10 e) is a large, strong species with a dull greenish-black body, at once recogni¬ 
zable by the conspicuously red-coloured palpi and forehips. The wings are dark blackish-brown with a purple- 
violet reflection. Beneath the cell-base of both wings there are narrow hyaline stripes. Brazil (Santos). 
4. Genus: fepliecosoina Btlr. 
It differs from the preceding genus by the upper median vein of the forewing rising below the radial 
veins; the third subcostal vein rises nearer to the apex than the lowest. The genus likewise contains very ichneu¬ 
mon-like, mostly smaller species. 
angustatum. S. angustatum Mdschl. (= testaceum Druce, gracile Klages) (10 e) exactly resembles Pseudosphex 
polistes in the colour and marking of the body; the hyaline wings have a brownish-yellow costal margin and 
nigriferum. proximal margin. From Guatemala, Panama, Surinam, Venezuela. -—- In nigriferuni Dyar described from 
Mexico (State of Vera Cruz: Santa Rosa) the abdomen is blackened with yellow hindmargins of the segments; 
the shaft of the antennae is black; the legs have no red colouring. Flying in August. 
perconstric- S. perconstrictum Zerny greatly approximates the preceding and particularly the dark shape of it, 
turn, and is easily discernible by the palpi being dark brown at the inner side and by the black-brown, not yellow- 
red antennae. The abdomen is black-brown with yellow hindmarginal edges growing gradually posteriorly 
narrower, the 2nd segment is below lustrous white. The wings are faintly yellowish hyaline, the costal-and 
proximal margins of the forewings narrowly light brown, veins and fringes of all the wings brown. Expanse 
of wings: 24 mm. Brazil (Sa. Catharina). 
rufipes. S. rufipes Bothsch. (10 h) differs from the similar angustatum by entirely white palpi, the quite black 
head with a yellow transverse line behind the base of the antennae, and the black-brown, orange-curled abdomen; 
the first segment is red-brown. The antennae are darker, only at the apex orange. Described from Venezuela. 
aurantiipes. S. aurantiipes Bothsch. (10 h). Palpi and forehead are yellow, the vertex black; collar yellow, in the 
posterior half black; shoulder-covers yellow, outside bordered by black; thorax in front black, behind yellow. 
The first abdominal ring is brown, the other part of the abdomen black, yellow-curled; the whole under surface 
is yellow, the legs orange. The hyaline wings exhibit an orange coloured costal margin and proximal margin. 
From Venezuela, Paraguay and Bolivia. The specimens from the latter two countries are considerably smaller 
than those from Venezuela. 
trinitatis. S. trinitatis Bothsch. (10 h). Head, palpi, thorax and legs are yellow, collar, shoulder-covers and thorax 
black-striped; the two first abdominal segments are brownish yellow, the second one with a red-brown ring, 
the rest of the abdomen black, at the costal margin of the segments yellow-curled. The hyaline wings have 
a brownish-yellow costal margin and proximal margin. Antennae red-brown. Trinidad, in December. 
arctatum. S. arctatum Wkr. (TO h) is recognizable by the orange-yellow abdomen curled in bluish-black; head, 
thorax and the 2 first abdominal rings are light yellow, with bluish-black spots and markings. The wings are 
hyaline with fine black veins and margins; costal margin and base of the inner margin yellow. Expanse of 
wings: 28 mm. Amazon (Ega). 
meridionale. S. meridionale Schrottky is much smaller than the preceding (expanse of wings: 22 mm). Head black, 
on the forehead and vertex yellow-banded; palpi, collar, shoulder-covers and under surface yellow. Antennae
