the temples, in dorsal view, nearly as wide as the eyes (Fig. 8). 
Antennae slender, segment three .75 X upper interocular distance. 
Propodeum convex, with a somewhat flattened declivity on posterior 
half; front tarsus with a comb of long^ somewhat flattened spines, 
four on the basitarsus, the apical one 1.7 X as long as second tarsal 
segment. Anal and cubital veins of hind wing interstitial ; third sub- 
marginal cell of fore wing narrowed by two-thirds above. 
Allotype. — cf, same data as type [MCZ]. 
Description of male allotype. — Length 9 mm ; fore wing 8 mm. 
Color exactly as in female, pubescence and pilosity also as in that 
sex. Clypeus 2.2 X as wide as high; middle interocular distance 
.62 X transfacial distance; upper interocular distance subequal to 
lower interocular distance; postocellar and ocello-ocular lines sub- 
equal. Antennae slender, segment three 2.5 X as long as wide, 
about half as long as upper interocular distance. Propodeum strongly 
convex and with a somewhat flattened declivity, as in female ; wing 
venation also as in that sex. Abdomen robust, slope of the first 
tergite higher than in elsinore; subgenital plate tectiform, broadly 
rounded apically; genitalia as shown in figure 5, differing from those 
of gastricus in the shape of the aedoeagus and in the slightly broader 
parapenial lobes.

Variation. — • The available females vary but slightly in size ( fore 
wing 9.5- 11 mm). In one specimen the clypeus is only 2.3 X as 
wide as high, and in two there is a small fifth comb-spine on the 
basitarsus. The males also show but little variation in size (fore 
wing 8-10 mm) and no noteworthy variation in color or other 
features. 
Remarks. — There can be no question that the name gastricus 
properly applies to the species occurring east of the Andes; although 
Spinola describes the species in the Historia de Chile , he remarks 
as follows: “El tipo de esta especie es una hembra del Brasil que 
M. Klug me habia enviado con el nombre que le he conservado. Los 
individuos de Chile que le he juntado, me han parecido enteramente 
semej antes a este tipo por su talla^ por sus formas y por sus coloresT 
Professor U. Parenti, of the Museum at the Universita di Torino, 
Italy, has sent me two females from the Spinola collection which
