The specimen collected by Kirk agrees in all ways with Say's de- 

 scription and can be separated from attenuaia by the following key: 



Wings uniformly brownish; legs entirely black abdominalis Say. 



Wings hyaline to subhyaline; trochanters, bases of tibiae and tarsi more or less, 

 whitish attenuata Norton. 



XIPHYDRIA ATTENUATA Norton 



Xiphydria attenvatus Norton, Proc. Ent. Soc. Phila., vol. 1, 1862, p. 144. 

 Xiphydria rufiventris Cresson, Trans. Amer. Ent. Soc, vol. 3, 1880, p. 34. 

 Xiphydria abdominalis Rohwer (not Say), Ent. News, vol. 29, 1918, p. 107. 



Additional material proves that this is not, as the writer had 

 previously considered, a synonym of abdominalis Say. (See above 

 discussion under abdominalis.) 



XIPHYDRIA CHAMPLAINI, new species. 



Female. — In color this species suggests erythrogastra Ashmead and 

 abdominalis Say, but may be distinguished from both these species 

 by its larger size, yellow spots on abdomen, more sculpturing on the 

 head, and the sharply constricted hind tibiae. Ignoring the color of 

 the abdomen, it will run to tibialis Say, but the head is not as coarsely 

 sculptured, the hind tibiae are longer and sharply constricted basally. 



Length, 14 mm. Anterior margin of clypeus with a median tooth; 

 head below lateral ocelli irregularly reticulate; front above the 

 antennae with two oblique low ridges forming a broad V; area 

 immediately behind a line tangent to lateral ocelli reticulato-granular; 

 vertex polished with a few poorly defined punctures; ocellocular line 

 distinctly longer than the postocellar line; cheeks and posterior 

 orbits, nearly to the top of eye, with dorsal-ventrad aciculations ; 

 orbital carina distinct, extending well above the top of eye; antenna 

 19-jointed, strongly tapering, not extending much beyond tegula?, 

 second joint half as long as third and equal in length with fourth; 

 prescutum broad, the anterior width subequal with the length, 

 rounded posteriorly so the caudad width is half the cephalad width, 

 with a distinct median longitudinal groove, the surface coarsely 

 reticulate and anteriorly, with a tendency to form a transverse ridge ; 

 notauli broad, foveolate; scutum reticulate, with the usual granular 

 areas laterally; suture between scutum and scutellum deep, foveolate; 

 scutellum reticulate, the posterior lateral areas more finely so ; mesepi- 

 sternum coarsely reticulate, with a tendency to striation below; 

 prepectus polished; mesostenium shining, with separate punctures; 

 mesepimeron rugose; metapleura coarsely reticulate; propodeum 

 shining, with separate punctures, the oblique depressions foveolate; 

 transverse depression at base of second (first gastral) tergite reticulate; 

 apical part of second tergite and all of the following (becoming finer 

 apically) granular; posterior tibia one-third longer than their tarsus, 

 constricted basally (more sharply dorsally), compressed and with a
