A New Polynema from Mexico (Hymen.). 



By A. A. GiRAULT, I'jrisbane, Queensland, Australia. 



The following species was found in a collection of Signi- 

 phorinse loaned to me for study by Dr. L. O. Howard. It 

 was at first identified as Polynema howardii (Ashmead) but 

 a comparison with the type of the latter shows such differ- 

 ences that the two cannot very well be the same. 



Polynema aspidioti sp. n. 



Normal position. Male. — Length, 0.65 mm. Moderate in size for 

 the genus. 



Similar to howardii but differing in the following details: 



The fore wings differ somewhat in shape but more specifically 

 in having shorter marginal cilia at the wing apex and along the 

 cephalic wing margin; in hozvardii the apical margin cilia and those 

 along the cephalic margin are twice longer than with this species, 

 nearly as long as half the greatest wing width; in aspidioti, however, 

 they are only about a fourth the greatest wing width; the fore 

 wing is shaped still more like that characteristic of ^tethynium 

 Enock. The species differ in coloration : in howardii all of the 

 legs are black or nearly so, but in aspidioti the first two pairs of legs 

 are pallid yellowish, only slightly dusky in places, the distal tarsal 

 joints blackish, while, excepting the trochanters, all of the posterior 

 legs are blackish; in howardii only the pro.ximal three tarsal joints 

 of all of the legs are yellowish ; in aspidioti all of the tarsal joints 

 of the caudal legs are black. Otherwise the two species are identical. 

 The line of foves across the scutellum is present here ; the 

 parapsidal furrows are complete; all of the antenna concolorous 

 with the body; petiole of abdomen yellowish; joints of flagellum 

 short, slightly more than twice longer than wide. 



From one specimen, 2-3 inch objective, i inch optic, Bausch and 

 Lomb. 



Female. — Unknown. 



A species characterized by the shape of the fore wing and 

 the arrangement of its marginal cilia. 



Described from a single male specimen mounted on a slide 

 with a species of Signiphora and labelled "1734. Aspidiotus 

 carinatus. On Lime. Cuautla, Morelos, Alex., July 2, 97. 

 Koebele." The host may be the Aspidiotus or else some Jassid 

 egg- 



Habitat: North America — Mexico (Morelos). 



Type : Type Xo. 14,027. United States National Museum. 

 Washington, D. C, one female in balsam.
