(Swezey) and 2 males (paratypes) collected in Honolulu in 
1906 (Dr. Perkins). 
Aphelinus maidis comes closest to A. nigritus and lapisligni 
Howard, and is distinguished by the characters given in the fol- 
lowing table. In Kurdumoff’s table of the European species it 
runs to varipes (Forster) and to hordei Kurdumoff, but does 
not agree with either, as both the middle and hind tibiae are 
black. 
Aphelinus gossypii n. sp. Fig. 6. 
Female. Head shaped exactly as in maidis as far as can be deter- 
mined in more or less shriveled specimens; antennae (Fig. 6) inserted in 
the usual position; the scape not quite four times longer than wide, 
excluding the radicle joint; pedicel almost twice as long as the first two 
funicle joints combined; first funicle joint about twice as long as wide, 
the second distinctly longer than the first and about one-third wider than

long, the third about as long as the first two combined, only slightly wider 
than long and a little less than one-third as long as the club; club rather 
broadly oval, one-half as wide as long, as long as the funicle and two- 
thirds of the pedicel combined, and provided with about six slender linear 
sensoria. Mandibles nearly as in maidis; maxillary palpi also the same, 
the labial pair with one joint about five times as long as thick; the termi- 
nal joint of both palpi in this species and also in maidis bears a slender, 
long, spine-like appendage, which may be a true but much attenuated seg- 
ment, but which is regarded as a seta in the preceding computation of the 
joints. Thorax and abdomen practically as in maidis; wings fully devel- 
oped, the speculum limited basad by a single row of coarser setae and by 
about two to five additional setae in the angle between this row and the 
marginal vein.
