of the second paragraph. Swezey (1907) quoted the first para- 

 graph with the exception of the last sentence. Under 1 this name 

 Quaintance and Brues (1905) give the following description of 

 the species : 



"Trichogramma is an extremely minute Chalcis-Qy, 

 scarcely visible to the unaided eye, and resembling- closely 

 the numerous other species belonging to this group. It 

 can be recognized readily, however, by the characteristic 

 arrangement of the hairs on the front wings, i. e., in 

 regular rows, and by the presence of only three tarsal 

 joints. 



Length 0.3 to 0.4 mm., the males being usually the 

 smaller. Color pale yellow, as a rule, although some 

 specimens are almost black. Eyes dark red and wings 

 hyaline. Head wider than the thorax ; antennae eight- 

 jointed, pedicel about two-thirds the length of the scape, 

 one small ring joint, the two joints of the funicle equal 

 together shorter than the pedicel, club conic ovate, a little 

 longer than the scape ; funicle and club beset with many 

 long hairs in the male and with short ones in the female. 

 Hairs of the front wings arranged in about fifteen lines. 

 Abdomen not so wide as the thorax, but as long as the 

 head and thorax together." [p. 118.] 



As Trichogramma pretiosa Riley, Riley first figured it in 1885 

 (p. 102, fig. 31) a,.d this figure has been reproduced without 

 change quite frequently by a number of authors, namely, by 

 Smith (1894). Howard (1896), Slingerland (1898), Smith 

 (1900) — bnt without lettering as in the original — Sanderson 

 (1902), Quaintance and Brues (1905) and Severin and Severin 

 (1908). In 1887, Riley (1887) reproduced it without name. 



B. Secondly, as Trichogramma miniitissimum, Packard 

 (1883) redescribed it as new quite as follows: 



Trichogramma minutissimum n. sp. 



Eighty specimens, five $ , seventy-five $ . Body uni- 

 formly pale testaceous or honey yellow, legs and antenna? 

 scarcely paler than the body, which is much paler than
