granular, with a few large punctures interspread; abdomen polished, 

 impunctate. 



Specimens from the same rearing vary from black to piceous. 

 The wings vary from clear hyaline to somewhat fuscous in the stigmal 

 area. 



PARASIEROLA DISTINGUENDA Kieffer. 



This is at once distinguished from celluhris by the quadridentate 

 mandibles and different antennae. (Kieffer ^ describes the antennae 

 of distinguenda thus: "Schaft etwas langer als das 2. und 3. Fiihler- 

 glied, diese nur wenig langer als dick, die folgenden wenigstens so 

 lang als dick.") Specimens which have been determined as this 

 species have the pronotum anteriorly wider than the length. These 

 specimens come from Texas and have been bred from Bruchus 

 yrosopidis (Hunter number 1410 of Bureau of Entomology) and an 

 unknown Bruchus (number 1700). 



Kieffer's variety gracilicornis has been taken at Los Angeles, 

 California, by Mr. D. W. Coquillett ; Mesilla Park, New Mexico, and 

 "Ckll, 2704 on Sisyrnbrinurn," by Prof. T. D. A. Cockerell. The 

 character of the antennae is perhaps great enough to consider this a 

 species. 



Family ElBIENIDiE. 



Genus ODYNERUS Latrielle. 

 ODYNERUS (STENODYNERUSj CANAMEXICUS, new species. 



Belongs to Stenodynerus of Saussure's "Synopsis of American 

 Wasps" and runs in his table to the species of this group to Tiuastecus 

 Saussure, but differs from the description of that species in a number 

 of points; supei'ficially separated by the red legs. 



Vertex bituberculate; second ventral segment sharply perpendicu- 

 lar anteriorly, the dorsal and ventral apical margins reflexed. 



Male. — Length, to apex of second segment, 10 mm. Clypeus 

 much broader than long, apex broadly rounded, middle arcuately 

 emarginate, the emargination bounded by a small tubercule laterally 

 surface mth separate, distinct punctures; front with close, distinct 

 punctures; vertex and posterior orbits with separated punctures of 

 the same size; ocelloccipital line subequal with the first two flagellar 

 joints; hrst joint of fiagellum distinctly longer than the second, but 

 not as long as the second and third; flagellar joints irregular; anterior 

 angles of the pronotum subdentate; thorax with distinct, rather close 

 punctures; metanotum perpendicular posteriorly, but not sharply so, 

 shghtly impressed medially; propodeum laterally and dorsally punc- 

 tured like the rest of the thorax, posteriorly separated into two large, 

 oval, shining areas by carinae; legs normal; first segment but little
