REPORT OF THE STATE ENTOMOLOGIST 1918 161 
orange-colored eggs are deposited in fissures at the base of rather 
soft, whitish resin lumps. Late in May exuviae showed that many 
adults had escaped while a few eggs were to be found. Infestation 
is most likely to occur in places where limbs have been sawed off, 
or in crevices filled with pitch. The larvae, prior to transformation, 
make a thin, papery cocoon, probably spinning in the same way as 
has been observed in Lasioptera. 
Male. Length 3 mm. Antennae about as long as the body, 
thickly haired, dark brown; fourteen segments, the fifth with stems 
three-fourths and one and one-half times their diameters; terminal 
segment, distal enlargement produced, with a length over twice its 
diameter, constricted near the basal third and with a long, tapering 
process apically, the latter with a length fully twice its diameter. 
Palpi; the first segment short, stout, subquadrate, the second rect- 
angular, with a length more than three times its diameter, the third 
a little longer, more slender, the fourth as long as the third, more 
slender. Mesonotum dull dark brown, the submedian lines sparsely 
haired. Scutellum reddish brown, postscutellum yellowish brown. 
Abdomen a dark yellowish brown; genitalia fuscous. Wings hyaline, 
costa pale brown; halteres pale yellowish. Coxae reddish brown, 
femora and tibiae yellowish brown, the tarsi slightly darker; claws 
long, stout, evenly curved, the pulvilli longer than the claws. Gen1- 
talia; dorsal plate short, broad, broadly and roundly emarginate, 
the lobes widely separated, narrowly rounded; ventral plate short, 
broad, scarcely tapering, broadly and roundly emarginate; style 
short, stout, narrowly rounded. 
Female. Length 3.5 mm. Antennae nearly as long as the body, 
thickly haired, dark brown; fourteen segments, the fifth with a stem 
one-fourth the length of the cylindric basal enlargement, which latter 
has a length about three times its diameter; terminal segment hardly 
produced, with a length about three times its diameter and apically 
with a rather long, tapering process; halteres yellowish basally, 
fuscous apically. Coxae dark brown, the femora and tibiae yellowish 
brown, darker apically, tarsi mostly dark brown. Ovipositor about 
one-third the length of the abdomen, the terminal lobes slender, 
narrowly oval, with a length fully three times the diameter. Other- 
wise nearly as in the male. Described from cotypes. Cecid. a1g30.

This species was reared May 20, 1915, from pitch on twigs of the 
long-leaved pine collected by Dr J. J. Davis at Talladega, Ala. 
It is closely related to R. resinicoloides Wlms., from which 
it may be separated by the longer basal portion of the stem of the 
fifth antennal segment and the distinctly greater emargination of 
the ventral plate.
