Three New Species of Aphelinus (Hym.). 

 By E. W. Rust, Assistant Government Entomologist. Lima, 



Peru. 

 Apb^inus capitis sfk. nov. 



9. Length. a7S mm.; cxpainc, 1.7 mm.; greatest width of fore- 

 wing. 0lJ7 nm. 



AntemuU loipe long and tknder. r e s chiug to lop of head, ftlighlly 

 comprcMcd farterally an*! of nearly equal croea Mdion throoghovt its 

 length except at the rxiremitica where it taper* sharply to the artica> 

 btiom; pedicel just a trifle lee* than half as loog as the scape and 

 nearly half again as wide at its widest point, iwrfsiiig gradasQy ia 

 diameter to a point just dislad of its middle where it i* half as wide 

 as lonK ; f unide joint i triangnlar in ootlinc. flvry sanll and so met i w es 

 (|uitc iniltkttnct. bring of less thMi half the sise of fwiide joint S. which 

 bttrr is of the same diameter as the pedicel and of a hit less than one- 

 third iu length; the pentdtinole joint b from lwo>thirds to foar- 

 fifths as long as the pedicel and just a shade wider, it b also three times 

 as long as the second ftmide joint which it jast ajtcecds in diameter ; 

 the second or lUtimate cloh joint, which b tam^rmmd laterally, b 

 three tiaKS as long as the pennhimate joint and at least caa-t hird 

 wider (when seen in broad outline), widest jnst distad of the ariddk 

 from where it upert rapidly to a hhnt point. A daep constriction 

 occurs between the two dnh joints separaliag them quite distiactly. 

 QoK with a few lungitad ia al kaeb aad (in eoaanon with the rest of 

 the antenna) sparsely hairy. 



Eyes hairy, licad and rest of body very siarilar to A. dmspukt How. 

 both in shape, position and aaaibcr of hairs or spiacs aad ia gcacral 

 sculpture, except that the mesoscatam aad awsoseatclhaa of A. em^Uit 

 are faintly longitudinally striated instead of showing the slightly teasel- 

 bted pattern of A. iiatfiiii. 



The forewings, in stru c tur e , arc aearcsl lite those of A. wtyHlas^idis 

 How., bat differ in that the discal dMs do not appear to be qtdic so 

 plentiful as in the hut naawd spedes. Ia A. nfitis there b a greater 

 difference in the length of the cilia on opposite sides of the hairless 

 streak, those distad being seemingly shorter than in A. mytUasfidU 

 and those proxfanad bciag slightly longer. The latter alia, although 

 of about the same irambers as those of A. mytilaspidis, more nearly 

 occupy all of the wing surface proximad of the hairless streak, thus 

 producing the impression that the wing b lets densely ciliated than in 

 A. utyHiatpidis, Hind wings as in other spedes of AfMimms. 



Color : Head brownish yellow to oraafe yellow ; eyes Wadrish ex- 

 cept with strong light through them, whea they appear garnet-colored : 

 ocelli dark red; aatennae coaeolorous with body or a trifle more
