S. albipalpe sp. nov. (26 i) greatly approximates the preceding and is at once recognizable by the 2nd albipalpe. 
and 3rd palpal joints being all white in front; the terminal joint is of a somewhat yellowish tinge; also the 2 
first joints of the antennae are white. The body is quite black, on the head and the edges of the shoulder-covers 
intermixed with sparse silvery-grey hairs; also the 2nd and 3rd segments of the abdomen are quite black, the 
former exhibiting laterally an oblique yellow streak. Venter likewise black, only the hindmargins of the segments 
somewhat yellowish-haired. Legs orange-brownish, forehips lemon-coloured. The hyaline-forewings are in the 
discocellular somewhat yellowish; the costal margin is yellow only between the uppermost radial and the lowest 
subcostal vein, as well as the proximal margin in the distal half. Expanse of wings: 24 mm. According to a 
S from the Amazon (Bang-Haas). 
5. Genus: PscBHlosphecosoma Strand. 
Very closely allied to Sphecosoma and differing merely by the presence of a very short upper median 
vein on the hindwing, whilst on the forewing the uppermost subcostal vein stands simultaneously with all the 
others on one single common pedicle. Only 1 species: 
P. vespoides Strand. Head and thorax are yellow; a transverse band on the vertex, spots on the collar vespoides. 
and shoulder-covers are black; so is the middle of the dorsum; on the hind part of the dorsum there is a 
T-shaped black figure. Abdomen above brown, beneath yellow like the legs; only the tarsi and hind tibiae 
are above brownish. Antennae red with black indented teeth. Wings brown-yellowish hyaline with brown 
veins, fringes, costal- and proximal margins. Expanse of wings: 24 mm. Brazil (Maranhao). 
6. Genus: Hontbopsyclie Hmps. 
Only one, sombre species being separated from the genus Pseudosphex by shorter palpi, the sudden, 
not gradual, expansion of the abdomen behind the footstalk; on the forewing the lowest radial rises separately 
from the lower cell-corner, the two median veins from a place below it, the middle radial above it. 
B. ruatana Druce (10 k) is a unicolorously black animal; on the forewing the marginal third as far ruatana. 
as down to the upper median vein is more thinly scaled and lighter; the lrindwings exhibit a small narrow 
hyaline spot below the base of the cell. Known from Honduras (Island of Ruatan). 
7. Genus: l*ompJlop$is Hmps. 
The sole species differs from Sphecosoma by the second abdominal segment not being strangulated as 
it is there, but also the third one; behind the very thin footstalk the abdomen expands rather suddenly, in 
order to taper off gradually towards the apex. No essential difference in the neuration. 
P. tarsalis Wkr. (= semihyalina Wkr., vespiformis Herr,-Schaff .) (10 i). The very peculiar, slenderly tarsalis. 
built animal is not to be mistaken for another species. Body dull greenish-blue-black, tarsi light-grey. On 
the hyaline forewings, a diaphanous brown band extends from the proximal margin before the middle to the 
costal margin and along the latter to the apex, a similar spot is situate at the inner-angle, cut off by the lower 
median vein. Transverse vein and costa deep metallic blue. Hindwings, except the hyaline base, diaphanous 
brown with a blue reflection. In the $ the brown band of the forewing does not reach as far as the apex and 
the spot of the inner-angle is absent. From Mexico (Tabasco) through Guatemala as far as Brazil (Para). 
8. Genus; l*o]iig>flio4les Hmps. 
This genus contains some species all of which resemble more or less the Amycles anthracina (12 1). The 
abdomen is but very little strangulated. On the hindwings the two median veins stand on a conjoint pedicle 
with the lower radial, the upper median vein rises from the lower close before the margin; the first radial vein 
and subcostal pediculate or not. 
P. albomarginata Druce (10 k) is the largest species, immediately recognizable by hyaline hindwings albomargi- 
with black veins and a rather broad marginal band and the short double ctenodont antennae. The white 
apical third of the forewing is very extensive and extends as far as the inner-angle. Costa Rica and Panama, 
also from Mexico. 
P. aliena Wkr. (= flavifascia H.-Schaff.) (10 k) is a true copy of Amycles anthracina and distinguishable aliena. 
not only by the differences of neuration, but also by the absence of the red neck-spots and the unicolorously 
black-brown hindwings. It differs from the preceding species by its smaller size, dark hindwings, a marginally 
grey-borclered, white apical spot of the forewing and, like the following species, serrate and ciliate antennae. 
From Guatemala, Venezuela, Brazil (Manas, Para, Ega) and Peru (Marcapata). 
P. postica Wkr. (10 k) differs from the preceding species by more stretched, more pointed wings, and postica. 
the much smaller extent of the whitish marginal spot which is to be seen only between the lower radial veins
