Kinsey: The Genus Neuroterus 
131 
Neuroterus subgenus Spathegaster Hartig 
Spathegaster Hartig, 1840, Germar Zeit. Ent., 11, pp. 186, 194. 
Neuroterus Dalla Torre and Kieffer, 1910 (in part). Das Tierreich, 
XXIV, p. 307. 
FEMALE. — Eyes rather large, extending more or less beyond the 
cheeks; cheeks narrow; malar space of moderate width, with a very 
shallow furrow; face scatteringly hairy; antennas brown, lighter 
basally, with 15 (only occasionally 14) segments, the third almost half 
again as long as the fourth; thorax large, narrow and elongate, higher 
than wide, longer than high, wholly or in part black ; mesonotum in 
part smooth but in part coriaceous and rougher, hairy laterally, with 
shallow but evident traces of parapsidal grooves; scutellum very nar- 
row, very elongate, peculiarly rectangular in outline, hairy laterally; 
mesopleurse in part smooth, in part finely and irregularly roughened, 
very rough dorsally; abdomen hardly larger than the thorax, angulate, 
sharply tapering anteriorly, the ventral spine rather short but dis- 
tinct; tarsal claws only moderately fine, distinctly toothed; wings 
clouded light brownish about both cross-veins and over part of the 
cubital cell, entirely ciliate, the front margins only short ciliate; areolet 
of moderate size to small and closed, extending in large part to one side 
of the apex along the cubitus; cubitus reaching the basalis at the 
midpoint; radial cell only moderately narrow, with the terminal portion 
of the subcosta quite short; the first abscissa somewhat arcuate rather 
than angulate; length, 1. 6-3.0 mm. 
MALE. — Largely agrees in color with the female; eyes consider- 
ably enlarged, distinctly protruding beyond the cheeks; antennae with 
15 segments, the third hardly curved, no longer than in the female; 
parapsidal grooves more evident; areolet about as large as in the female; 
radial area open. 
GALL. — Monothalamous, more or less separable, generally circular 
and flattened, sometimes very definitely formed; a leaf gall. 
RANGE. — Europe, adjacent Asia, and northern Africa. 
TYPE . — Neurotems petioliventris Hartig. Monobasic. This came 
from Germ.any (Berlin or Halle), but was so poorly described that it 
has not been further recognized by any later student. Its size is typical 
of our present group, and the term Sjmtheg aster has been regularly 
used by European workers for just the species included below. Prob- 
ably no sounder interpretation of the type can be made in the future, 
and even tho not too well founded, our present restriction may cause 
the least confusion. 
I have examined material of the following species ^and 
find they belong to this subgenus.
