68 THE CANADIAN ENTOMOLOGIST. 



The Massachusetts specimen was cited under the description of 

 Lampronota varia, Cress. (Trans. Am. Ent. Soc, III., 164, <$), as a 

 variety. Varia, however, is a quite constant species, a series of twelve 

 specimens showing no great extremes either in sculpture or coloration. 

 The metathorax of H. relativa is very distinct from that in varia, which 

 lacks longitudinal lines, and is more finely and uniformly sculptured 

 otherwise. The yellowish cast of the wings and yellowish abdominal 

 ornamentation is also characteristic of varia, and offers a good superficial 

 difference for separating these two species. 



Nadia apalachia, n. sp. — Head and thorax more or less finely and 

 closely punctured. Mandibles heavy and incurved. Abdomen finely 

 sculptured. Areolet sessile. 



r? . — Length ic.5 mm. Clypeus with a few strong punctures, 

 elevated transversely. Face closely, indistinctly punctured, opaque, front 

 also opaque, punctures well separated. Cheeks somewhat shining, 

 minutely sculptured and with sparse punctures. Mandibles heavy, 

 incurved rather strongly. Flagellum thirty-four jointed. The superior 

 half of propleura distinctly punctured, somewhat shining, the inferior 

 half obscurely sculptured, opaque. Punctures of dorsum very close 

 anteriorly, more separated posteriorly, from opaque to faintly shining. 

 Scutellum arched, somewhat impressed on each side, closely punctured. 

 Mesopleura with an abbreviated longitudinal raised line anteriorly, not 

 so distinct, the integument punctured somewhat like dorsulum, the 

 punctures closer and finer below than above. Metathorax gently 

 rounded, almost uniformly, very closely punctured. The division 

 between the metanotum and metapleura only indicated by a very faint 

 impression. Wings hyaline, with a faint yellowish cast. The first and 

 second transverse cubiti uniting on the radius, forming an acute angle. 

 Stigma and nervines almost uniformly light brown. First dorsal segment 

 opaque, with fine, close punctures, the spiracles not strongly protuberant, 

 the remaining dorsal segments more finely sculptured, the apical ones 

 becoming shining. Almost uniformly pubescent, abdomen sericeous. 

 Black : mandibles except base and apex, clypeus, face, part of 

 the scape, a pointed mark on anterior margin of dorsulum, base of 

 the wings, tegular, a spot aside and below, a spot on scutellum, four 

 anterior legs more or less, apex of posterior coxre, apex of femora, the 

 tibia excepting apex (more or less), and tarsi yellow. Part of posterior
