 "(14) Euderiis columbjana^ n. sp. 



" Ç . Length, 10 inch. Dull brown, or bronzy-green, its whole surface, 

 including the abdomen, strongly, confluently punctate. Head transverse, 

 not wider than the posterior part of the mesothorax, and with only a 

 slight antennal groove in front. AntennEe about as long as the thorax, J 

 eight-jointed; scape slender, yellowish brown; flagellum dark brown, 

 about twice as long as the scape, pubescent, the pedicel shorter than the 

 funicle joint, the latter joint the longest, about twice as long as wide, the 

 following joints being not much longer than wide, sub-moniliform. Thorax : 

 collar transverse, rounded before ; mesothorax with parapsidal grooves 

 well defined ; scuteilum longer than wide, without grooves, rounded be- 

 hind, sides parallel. Abdomen conic-ovate, cylindric, one-third longer 

 than head and thorax together, the segments of nearly equal length. Legs 

 dark brown, trochanters, knees, fore and middle tibiœ, and all the tarsi 

 honey-yellow, hind tibi^ dusky in the middle. Wings hyaline, fringed 

 with short ciliœ ; the veins brown, the marginal is twice the length of 

 the submarginal, the stigmal short, while the postmarginal is wanting.

I have been unable to connect, directly, Euderus cohunbianus Ash- 

 mead with TricJiaporus columbiamis Ashmead listed in Smith's (1900) 

 Catalogue of the Insects of New Jersey, but as I cannot, in addition, find 

 the original description of the latter, conclude that they are synonymic 

 and that Ashmead intended the former species. 



In characters, the species does not agree with either genus {Euderus 

 Haliday or TricJiaporus), as now limited (but does with the definition of 

 Foerster, 1856), and can hardly belong to the Tetrastichini as limited by 

 Ashmead (1904), the scuteilum having no grooves. From the description 

 of the species quoted in foregoing, being an eulophid with a long marginal 

 vein, short submarginal and stigmal veins, without a postmarginal vein and 

 grooves on the scuteilum, with 8-jointed antennas and complete parai)sidal
