TRTcnoGKA:\r:\rir)AE. 



Two of the species of this family here described, were reared 

 from the eggs of Jassidae, attacking sugar-cane in Mexico. 

 One of these I cannot place in any of the numerous genera des- 

 cribed by Girault, who has done excellent work on the N^orth 

 American species. This family has been divided into two sub- 

 families on the character of the hairs on the wing, but it ap- 

 pears to me than this division is unnatural, separating genera 

 that are really allied, and even as a matter of convenience is of 

 little practical use, since it is quite doubtful to which family 

 certain forms should be referred. This is the case with the 

 genus J<issidu})hih()ra described by me. All the Trichogram- 

 midae known to me have a sessile alxlomen, penetrated by the 

 thoracic ])hragma, and 1)V the longitudinal thoracic muscles. 

 This is also the case with the A])hclininae of the family Eulo- 

 phidae and with certain of the JMymaridae, b\it is otherwise 

 rarely seen in the Ohalcid series of families. The species of 

 Pentdrth ran here described, destroys the eggs of the very in- 

 jurious moth-borer, Diatrnca saccharaJis.

Yellow, the head dark, scirdid brown, meso- and metapleura 

 above the coxae conspicuously dark, like the coxae themselves, 

 ti'ochanters yellow, the femora and tibiae embrowned or dark- 

 ened, the apical joint of all the tarsi black or blackish. The 

 basal abdominal segment above is more or less dark, as also is 

 the sheath of the ovipositor, and generally more or less of tlie 

 apex of the abdomen. Pronotum sometimes infuscate. Wings
