with a salient rim, shinin", coarsely retieulatetl, the reticulations irregular in form 
hut about the same size. Segment 1 with a few small scattered punctures; segments 
2-3 with numerous fine pnnelures at base, the apical margins depressed, smooth 
and shining; segments 1-3 dark red; apical segments black; .segment 3 in some 
specimens partly clouded with black. 
(S '. — Length 0 mm. Entirely black, resemljles the male of S. dichruu.i, but is 
smaller with finer punctures; the apical margins of the abdominal segments are 
depressed, impunctate, and obscurely testaceous. One male taken on Solidago, 
Aug. 9, has only two snbmarginal cells. 
The female was taken on ('rataegus coecinea, .June 14; the male on Aralia 
hispida, July 30; and Solidago Aug. 17. This species is allied to S. (lickrou.'t, but 
typical sj)ecimens may be easily separated by the smaller size of both sexes. It is a 
neater, more shining species with finer sculpturing, anil in the female the abdomen 
is more largely clouded with black. A female from Spiraea salicifolia, July 30, is 
smaller and duller, the red of the abdomen lighter, with the black apex better defined, 
and the wings not so brown. It may represent a distinct species, but more material 
is necessary to decide this question, (’omjiared with the various Rocky ^Mountain 
and Pacific Coast species, S. pw.iplium.'i is not much like any of them, but it has a 
very close resemblance to the Piuropean S. gibhu.s. The male of qihhu.'t, however, 
usually has the abdomen red, e.xcept at base and apex.

9. — Ixmgth about 5 mm. Head and thorax black; abdomen red with black 
apical segments; mandibles lively red with the base black, bidentate, the inner tooth 
small; antennae black, the flagellum faintly reddened beneath. iMesothorax shining, 
with rather large well separated punctures, the median sulcus distinct but shallow; 
wings dusky hyaline with dark brown nervures and stigma, tegulae testaceous' in 
front, area of metathorax well-defined, semicircular with parallel longitudinal rugae, 
but not reticulated, though there are indications of cro.ss lines, giving the rugae a sort 
of beaded appearance. Abdomen impunctate, segments 1-2 red, segment 3 suf- 
fused with blackish, apical segments black. 
C?. — Length about 5i mm. Head and thorax black; abdominal segment 1 
black with apical margin yellowish-red; 2nd segment yellowish-red at ba.se, sides 
and a|)cx, center black; apical segments black. Breadth of head about ecpial to the 
length; mandibles black, rufous at tips; antennae black, joint 4 nearly equals 3. 
Mesothorax shining, rather coarsely jumetured: semicircular enclosure of meta- 
thorax well-defined with ]>arallel rugae. Wings a light shade of fuscous, stigma 
and nervures brown, tegulae black.
