or the quarter of an orange. It is about equally divided between the two surfaces 
of the leaf; no rosy cheek. Generally there is but one gall on a leaf; one leaf was 
seen with three upon it. Length 0.23 to 0.50 iuch. One hundred and thirty-one 
specimens. Gall mature July 30. 
Larva. — Three or four of these July 30, did not apparently differ from those of 
s. pomum examined the same day. When the larva quits feeding iu the gall, there 
remains nothing of it but a shell as thin as paper. All the imagoes bred pupized 
inside the gall ; but there was no earth within the breeding vase. — Walsh, Proc. Ent. 
Soc. Phila., vi, p. 257. 
Two females, a bred specimen from Illinois (Walsh's type?) and a 
collected specimen from Massachusetts, and one male (Walsh's type!) 
apparently reared with the female described above. (Coll. Am. Ent. 
Soc.) 
Ncmatus inquilinus Walsh is unquestionably identical with this species. 
Galls probably belonging to this species have been received from the 
following localities: Lafayette, Ind., F. M. Webster, August 15, 1890, 
from which were obtained two parasites, Sympiesis sp. and Murytoma 
studiosa Say, supposed to be parasitic on Anthonomus sycophanta Walsh ; 
Eichfield Springs, N. Y., Th. Pergande, collector, September 28, 188G. 
Cadet, Mo., J. G. Barlow, collector, September 24, 1890. 
26. Pontania sulphurea new species. 
Female. — Length 4 mm.; rather slender, glistening; head and thorax 
somewhat coarsely punctured ; clypeus circularly emarginate, lobes 
triangular; ridges of vertex inclosing ocellar basin present, but not dis- 
tinctly denned ; frontal crest small; antennal fovea very shallow, almost 
wanting; antennae, scarcely as long as head and thorax, filiform, joints 
3 and 1 subequal; sheath very narrow, elongate, tapering toward 
rounded tip; claws large, deeply notched; outer veins of discal cells of 
hind wings interstitial; cerci very short, tapering rapidly from base. 
Color sulphur yellow; antennas, quadrate spot on vertex inclosing 
ocelli, large spot on each of anterior lobes of mesonotum, the post scu- 
tellum and two or three spots on the succeeding sclerite, band on basal 
plates, and on proximal segments of abdomen brownish black, lighter 
on abdomen; antenna 1 fulvous beneath, dusky toward tips; sheath 
edged with brown on the dorsal and apical margins; veins light yel- 
lowish brown; stigma and costa lighter basally. 
Male. — Agrees in general characters with the female. The dorsum of 
thorax is black, and the basal segments of the abdomen are black cen- 
trally, forming a narrow dark stripe extending more than half way to 
the tip of the abdomen. 
One female and one male. Montana and Nevada. (Coll. Am. Ent. 
Soc.) 
27. Pontania rugulosa new species. 
Male. — Length 4 mm.; rather slender; head roughened, coarsely 
punctured, thorax with finer puncturing; clypeus deeply, narrowly 
emarginate, lobes triangular; lateral walls of ocellar basin indistinct or
