solete or obsolete in this s|)eeies; the second transverse vein is smooth, with¬ 
out projection inside of the radial area, although sometimes slightly angular. 
The sexes in this species are more alike than in any other; they are, 
however, easily distinguished by the structure of the abdomen. 
The specimens which I possess in considerable number, were com¬ 
municated to me by Mr. E. Norton. 
As already noticed above. Dr. Plarris’s C. ^emi'picea cannot possibly 
refer to this species. (Compare about it the description of the gall, 
under No. 4.) 
Rhodites rosee Linn. 
% Black. 
9 0.13—0.15 long, abdomen red, black at tip. 
9 Head and antennae black, mandibles reddish, thorax black, pubescent, 
smooth and but finely sculptured, parapsidal grooves not deep, and quite in¬ 
distinct when viewed from above, stopping some distance before reaching the 
humeri, intermediate furrows well marked, shining at bottom, pleurae with two 
oblong, shining spots, abdomen red, the four last segments black ,• feet red, 
coxae and tip of tarsi black, wings pale brownish, with a brown cloud on the 
radial area and its surroundings \ the second transverse vein, which is angular, 
has a small, but distinct projection within the radial area; areolet of moder¬ 
ate size. 
The sculpture of the thorax is not dense enough to render it opaque 
and it retains some of its gloss; in this respect it resembles the if. 
verna. By all means, the black tip of the abdomen renders this spe¬ 
cies sufficiently distinct. 
The male seems to be very rare, as among 200 specimens which 
passed through my hands, thanks to Messrs. Norton and Akhurst, there 
was only a single % . I was unfortunate enough to lose it in attempt¬ 
ing to paste it on paper. The glimpse I had of it was sufficient to 
show that its abdomen was black, and its wings less tinged with brown. 
(The European Rhodites rosse % has also a black abdomen.) 
The gall of this species has been described above (under No. 1); it 
is similar to the European gall, known as the hedeguar of the rose. I 
could not perceive any difference between my specimens of the Euro¬ 
pean R. rosse Linn, and the American insect.
