in length but not in width, the whole flagellum tapering gradually 

 from base to apex, the ultimate joint very slender and cone-shaped. 

 Mesoscutum and scutellum as in the female. 



The mesoscutum and scutellum in both sexes when viewed under 

 high magnification in balsam appear finely and uniformly reticulated, 

 the reticulations more or less longitudinally elongated.

Crawford stated that no satisfactory means for distinguishing the 

 females of tarsalis and aslimeadi could be found but that the males 

 could be separated by the fact that in tarsalis the fuuicle was appar- 

 ently 4-jointed, while in ashmeadi it was apparently 3-jointed. 



C. F. W. Muesebcck, of the gypsy moth laboratory at Melrose 

 Highlands, Massachusetts, recently sent the writer a series of 13 

 males and 12 females of Pleurotropis, all reared from cocoons of 

 Ayanteles melanoscelus collected at Frankhn, New Hampshire, and 

 recorded under Gypsy Moth Laboratory No. 12599c. Among these 

 males are specimens duplicating in antennal characters as well as in 

 every other way the type males of both tarsalis and ashmeadi. In 

 all of them the flagellum beyond the ring-joints is comprised of five 

 joints, but in some specimens all five joints are distinctly separated 

 and shortly pedunculate, while in others the ultimate joint is closelj' 

 joined to the penultimate, the peduncle apparently entirely lacking. 

 The first mentioned condition is exactly that found in the type of 

 tarsalis, while the last mentioned is similar to that of the type of 

 ashmeadi. The series of males exhibits a distinct gradation from the 

 one form of antenna to the other. The type females, as indicated by 

 Crawford, are inseparable and agree in every way with the females 

 of the Muesebeck series. There seems no reason to suppose that the 

 latter rearing represents more than a single species and the writer is 

 therefore convinced that tarsalis Ashmead and ashmeadi Crawford 

 are the same species. 



DASYSCAPUS, new genus (OMPHALINI) ' 



It is not easy to decide the correct position of this genus in the 

 Eulophidae. It runs best in Ashmead's classification to the tribe 



' The description of Ooethcana Olrault (Ins. Ins. Mens., vol. 8, 1920, p. 97) fits this insect almost exactly, 

 but inasmuch a= the author of that genus places it in the family Mymaridae, a group with which the 

 present form has no relationship, and since the description is insufficient for positive i'leiitification, one 

 is compelled to assume the two are not the same.
