ODONTOMERUS ALASKENSIS, new species. 



Colored like meUipes, but may be separated from it as well as from 

 all other species in North America by the obsolete carinse of the pro- 

 podeum and by the short prescutum. 



Female. — Length to the apex of the abdomen 8 mm., length of the 

 ovipositor 8 mm. Face shining with a few distinct scattered punc- 

 tures; cheeks and head above the antennae practically impunctate; 

 postoceUar line one-third shorter than the oceUocular line; area 

 between lateral ocelli separated by a furrow; antennae much longer 

 than the head and thorax, third and fourth joints subequal; anterior 

 face of the pronotum coarsely punctured, in the middle the punctures 

 become confluent so as to give a striate appearance; mesepisternum 

 shining, practically impunctate; prescutum short, as wide as long, 

 not sharply defined posteriorly, it and the scutum shining, very 

 sparsely punctured; propodeum opaque, finely punctured or punc- 

 tato-reticulate; carina practically obsolete but indicated under high 

 power when the areolation is as in Tnellipes; first abdominal segment 

 longitudinally striato-granular, faintly dentate at the spiracles with a 

 broad longitudinal depression; the apex of the second and the entire 

 following segments shining, practically impunctate; propodeum with 

 sparse gray hairs. Black; palpi piceous; legs entirely rufous; wings 

 dusky hyaline, iridescent; venation dark brown. 



Sitka, Alaska. Described from two females collected by T. Kin- 

 caid. The paratype is 6^ mm. long, and slightly piceous; otherwise 

 it seems to be the same. This species was determined as mellipes by 

 Ashmead. 



Type.— Csit. No. 15373, U.S.N.M. 



ODONTOMERUS ERRANS, new species. 



Related to mellipes (Say), but may be readily separated from that 

 species by having the basal area of the areola separated by a trans- 

 verse carina (in mellipes the basal area and the areola are confluent). 



Female. — Length to the apex of the abdomen 12 mm.; length of 

 the ovipositor 12 mm. Face closely, finely punctured; head above 

 the antennae shining with a few irregular punctures; lower part of 

 cheeks with large, widely scattered punctures; the postoceUar line 

 much shorter than the oceUocular line; no furrow between the lateral 

 ocelli; antennae a little longer than the head and thorax, the third 

 antennal joint one-third longer than the fourth; thorax densely 

 pubescent, subopaque with a few widely scattered punctures; notauli 

 complete, not foveolate; anterior face of the pronotum transversely 

 irregularly striate; sides of the propodeum shining, dentation of the 

 propodeum occurring below the dorsal lateral angle; basal area 

 trapezoidal in outline, about four times as wide basaUy as apicaUy;
