REPORT OF THE STATE ENTOMOLOGIST I918 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. Geni- 

 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. ai93o.

This species was reared May 20, 191 5, 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.
