beyond the basal vein. Black; four anterior legs and the posterior

Fort Yukon, Alaska. Described from one female collected by 

 L. M. Turner. 



Type.— C&t. No. 15367, U.S.N.M. 



XYLONOMUS (MAEROPHORA) EASTONI, new species. 



Female. — Length to the apex of the abdomen 10 mm., length of the 

 ovipositor 10 mm. Face transversely striato-punctate ; area between 

 the antennae and the ocelli punctate, more sparsely so above ; posterior 

 orbits longitudinally striate; postocellar line almost twice as long as 

 the oceUocular line ; anterior face of the pronotum with distinct sepa- 

 rated punctures, lateral margin of the pronotum with an el^ngate, 

 small tubercule; prescutum poorly defined, anteriorly finely granular, 

 laterally rather coarsely reticulate, posteriorly transversely, irregu- 

 larly striate; scutum transversely, irregularly striate; scutellum with 

 distinct separate punctures; mesepisternum shining, irregularly 

 striato-punctate; sides of the propodeum reticulate, dorsally the 

 propodeum is punctato-reticulate ; basal area and the areola separated 

 by a transverse carina; basal area trapezoidal in outline, about four 

 times as wide basally as apically; areola hexagonal in outline, more 

 than twice as long as its greatest width, narrowing at the anterior 

 third, subparallel posteriorly; propodeum not dentate laterally; 

 abdomen finely granular; first abdominal segment without carinse or 

 depressions, subdentate at the spiracles; transverse median of the 

 fore wings distinctly beyond the basal vein; third antennal joint 

 slightly shorter than the fourth. Black; four anterior legs and the 

 posterior coxae rufous; wings hyaline; venation dark brown. 



Fall River, Massachusetts. Described from one female collected 

 May 31, 1910, by N. S. Easton, for whom the species is named. 



Type.—Csit. No. 15368, U.S.N.M. 



XYLONOMUS (MAEROPHORA) DUPLICATUS, new species. 



Superficially this species is like albopictus Cresson, but may be 

 readily separated from that species by the areola and the basal area 

 of the propodeum being separated by a transverse carina (in albo- 

 pictus the areola and the basal area are separated by a longitudinal 

 carina) . 



Male. — Length 10 mm. Slender. Entire head shining, practically 

 jmpunctate; anterior face of the pronotum finely punctured, ven- 

 traUy and posteriorly foveolate; dorsal lateral angles subdentate; 

 prescutum long; the notauli foveolate posteriorly; scutum and pres- 

 cutum with distinct, well separated punctures; mesepisterum shining 

 with a few widely separated punctures; propodeum shining; areola 

 and basal area separated by a transverse carina; areola hexagonal
