ing joints. Thorax: mesothorax with a broad brown stripe down the 

 middle; base of scutellum and of metathorax black, the latter has a 

 well defined transverse subarcuated carina. Wings yellowish-hyaline, 

 with a fuscous spot at tip; nervures fuscous, stigma fulvous; areolet 

 small, subtriangular, oblique. Legs bright yellow, the two apical joints 

 of the posterior tarsi black. Abdomen polished, smooth, yellow, the 

 base of the first five segments rather broadly black ; apex tinged with 

 fulvous ; ovipositor slender, rufous, exserted two-thirds the length of 

 the abdomen. Length 5 lines; expanse of wings 10 lines. 



Collection. — Ent. Soc. Philad. Two specimens. 



Very closely allied to P. cubensis, but is smaller and easily distin- 

 guished by the fuscous spot at the tip of the wings; the joints of the 

 antennae, beyond the second, are shorter, and the ovipositor longer and 

 slenderer. 



Pimpla consimilis, n. sp. 



Yellow: antennae blackish. 3rd joint as long as the 1st and 2nd together; me- 

 sothorax with three brown stripes; base of the first five abdominal segments, 

 and the hind tarsi, black; wings yellowish-hyaline, fuscous at tip. 



Female. — Yellow, shining; antennae as long as the body, blackish, 

 rufous at base above, yellowish at base beneath, 3rd joint as long as 

 the 1st and 2nd together, as in terminalis. Thorax: mesothorax with 

 three longitudinal brown stripes ; extreme base of metathorax black, 

 sculptured as in terminalis. Wings deep yellowish-hyaline, with the 

 apical margin, especially at the tip of the marginal cell, fuscous ; ner- 

 vures fuscous, stigma fulvous; areolet small, subtriangular or obliquely 

 subquadrate. Legs yellow, the posterior tarsi black. Abdomen shining, 

 the base of the first five segments black, very narrow on the filth seg- 

 ment ; ovipositor rufous, slender, scarcely half as long as the abdomen. 

 Length 4J lines; expanse of wings 9 lines. 



Collection. — Ent. Soc. Philad. One specimen. 



Closely allied to P. terminalis, but the thorax is trilineated, the wings 

 darker, and the hind tarsi entirely black. It may, however, be a vari- 

 ety of that species. 



Pimpla tricincta. n. sp. 



Yellow; antennae, hind femora and apical half of abdomen, rufous; three 

 stripes on mesothorax, and basal half of the three first abdominal segments, 

 brown ; wings yellowish-hyaline. ^ 



Female. — Yellow, shining; tips of mandibles black; occiput rufous; 

 antenuae as long as the body, rufous, paler at the base beneath, the 

 joints as in cubensis. Thorax: mesothorax with three broad, longitudi- 

 nal, brown stripes; the sutures between the pectus, pleura and meta- 

 thorax, the base of the scutellum and of the metathorax, blackish, the
