NO. 1927. DESCRIPTIONS OF NEW HYMENOPTERA, 5— CRAWFORD. 177 



elevation, smooth, polished ; medial area of propodeum slightly wider 

 than the depressions on either side of it; prepectus closely punctured; 

 mesopleurse smooth; legs white, the coxae blue-green; apical half of 

 first abdominal segment, except apical margin, finely reticulated with 

 impressed lines. 



Male. — Length about 1.25. Similar to the female except hi sec- 

 ondary sexual characters; the petiole as long as the hind coxae. 



Habitat. — Santa Lucrecia, Vera Cruz, Mexico. 



Host. — CirpJiis liumidicola. 



Type.— Csit. No. 14810, U.S.N.M. 



Described from specimens from a large bred by Mr. F. W. Urich, 

 after whom the species is named. 



In some of the paratypes the sculpture of the scutellum is absent 

 except basally and laterad and in the male the reticulated area of the 

 fu'st abdominal segment is greatly reduced and the sculpture weak- 

 ened. 



In my table of the species of the genus from the West Indies ^ this 

 runs to nigroaeneus Ashmead, which has the whole front above the 

 transverse furrow sculptured ; the sculpture of the mesoscutum much 

 stronger, consisting of well elevated carinae, the sculpture of the scut- 

 ellum more distinct, etc. 



In Doctor Ashmead's table the South American species,^ it runs to 

 aeneicollis Ashmead, wliich has the sculpture of the face below the 

 transverse furrow resembling reticulations, above the furrow with 

 delicate, indistinct reticulations; the lateral carinas of the scuteUum 

 apically curve inward and meet the median carina, etc. 



Genus PLEUROTROPIS Foerster. 



In this genus are placed species of the tribe Entedonini which have, 

 as I understand them, the characters assigned to the genus by Foerster. 

 The propodeum has two longitudinal medial carinas which at the apex 

 of the propodeum turn laterad; also between the spiracles and these 

 carinas, at about the point usually occupied by the lateral folds, 

 another longitudinal carina. 



The species found in the United States which answer the above 

 characters have been described in so many genera that a table of them 

 is given and also their synonomy. Pleurotropis leucopis Ashmead has 

 only one medial carina and no lateral carinas and is therefore excluded.
