C. Thirdly as Tricho gramma odontotce by Howard (1885 b) 



"3. Trichogramma odontotae, n. sp. Female. — 

 Length 0.55 mm., expanse 1.12 mm. Color : eyes red, head, 

 antennae, thorax and basal joint of abdomen orange yel- 

 low, all legs light fuscons, remainder of abdomen light 

 brown. Antennae except scape and including pedicel with 

 a few short sparse hairs. Basal portion of fore wing in- 

 cluded by the stigmatal vein slightly fuscous, remainder 

 hyaline. 



Male. — Length averages about .05 to .1 mm., shorter 

 than $ , with wings of about the same proportionate 

 length. Colors the same except that the abdomen is 

 darker, and the fuscous patch on the base of the fore 

 wings is more pronounced. In the balsam-mounted speci- 

 mens no complete division of the flagellum into joints 

 can be observed and the antennae appear 3-jointed (scape 



1, pedicel 2, flagellum 3). Conspicuous whorls of hair 

 are present, however, indicating possible sub-divisions. 

 The appearance is much like that of the $ antennae of 

 Tr. erosicornis, Westw. (Trans. Linn. Soc. London, Ser. 



2, Vol. I (1878) PI. 73, figs. 24 and 25) for which West- 

 wood erects the sub-genus Aprobosca. 



Described from $ and $ specimens bred during the 

 month of July from the egg masses of Odontota suturalis 

 on Locust at Washington, D. C." [p. 117.] 



This description has never been repeated. 



D. Fourthly and finally it was redescribed as new under the 

 name Trichogramma intermedium by Howard (1889a) in this 

 manner : 



Trichogramma intermedium sp. nov. PI. 89, fig. 8. 



Male. — General color dirty yellow in effect; face 

 bright yellow, eyes and ocelli red, antennae slightly 

 dusky ; mesonotum very light yellow-gray ; metanotum 

 yellow ; abdomen above slightly darker than mesonotum ; 

 all coxae dusky, hind femora slightly dusky above, re- 

 mainder of legs dull yellowish. Wings with a slight cloud 

 below submarginal vein. The nearly straight line of hairs 

 running downwards from tip of stigma consists of five 

 hairs, the first one sometimes included in stigmal club.
