ODONTOMERUS DICHROUS, new species. 



This species is related to licolor Cresson, but may be separated by 

 having the sides of the propodeum finely punctured, the notauli 

 finely, irregularly foveolate, the propodeal tooth on the dorsal lateral 

 angle, the areola of the propodeum not three times as long as the 

 basal width and sharply angulate, as well as other minor characters. 



Female. — Length to the apex of the abdomen 13 mm.; length of 

 the ovipositor 17 mm. Face with distinct, well-defined pimctures 

 which are closer in the middle; head above the antennae polished, 

 with a few irregular scattered punctures; the lower portion of the 

 cheeks finely, irregularly punctured; ocelli in a low triangle; the 

 postocellar line much shorter than the oceUocular line; a deep furrow 

 between the lateral ocelli; antennae much longer than the head and 

 thorax, the thu'd joint about one-third longer than the fourth; 

 thorax shining, polished; scutum with a few irregular punctures; 

 notauli finely, irregularly foveolate posteriorly; scutellum rather 

 more densely punctured than the scutum; the anterior face of the 

 pronotum punctate; the mesepisternum nearly impunctate; sides of 

 the propodeum finely punctured, below the longitudinal carina 

 striato-punctate; basal area and the areola confluent, the areola 

 about two and one-half times as long as its greatest width, broad- 

 ened near the middle where it is sharply angulate; posterior face of 

 the propodeum transversely and obliquely rugose; dentation of the 

 propodeum on the dorsal lateral angle; first abdominal segment 

 longitudinally striato-granular, tuberculate at the spiracles; base of 

 the second abdominal segment transversely striato-reticulate, apex 

 of the second and the following abdommal segments impunctate; 

 legs and venation of the normal type. Black; legs and abdomen
