PSYCHE 
[April 
frrus Linnaeus, is treated in a like manner; it is a larval ])arasite of certain Diptera. 
And attention is also directed to the record of Elanmu.i nlhicnxa Howard from 
of IlanUarchia arcliippiix Cramer, more or less discredited by both Howard and 
Ashmead (the latter, in till.)', and to the erroneous rceonl of 1 lad nmol ux Irpiororixa' 
Howard on Leptororixa tipuloidrx DeCeer (Ashmead, 1887 1>, p. 119; id., 1898 a, 
p. 231). Poliinrnm (Webster, 1903, j). 33) should be Polijncma, .so Air. Webster 
informs me. The li.st requires no further e.xplanation. 
Our knowledge of egg-parasites does not eonqiare favorably with that of the 
parasites of the larva. But for the writings of Howard, Ashmead, and Riley and 
Howard, the recorded rearings would be very meagre indeed. It is mainly through 
the efl'orts of the two former, that so much is now known of this most important 
ela.ss of in.seet jiarasites, and we are at the pre.sent day much more advanced in this 
respect than are our Phiropean neighbors. 
Egg-parasites are not diffieult to rear, and being, perhaps, the most potent 
enemies of many of our injurious insects, it is desiraljle that greater care and more 
thoroughness be taken in rearing work; so that on aeeonnt of their minute size, 
they are not overlooked. 
In connection with this li.st, I mention some of the insects which are known to 
be hosts of egg-parasites, the latter .still unknown. In the Lepidoptera, Anixota 
riihicunda Fabr., Euproriix chrpxorrhora Linn. (Europe), Junnnia coenia Htibner, 
Mahirnxoma dixxtria Htibner, Megathymux yurctr Boisd. et Leconte, Pnoniux r.rrnr- 
ratux Smith et Abbot, Thorybrx pyladrx Seudder, and Vanexxa rnrdui Linn, have 
been recorded as being attacked by egg-jiarasitcs. Among the Hemiptera is Scrinrtlia 
trivittata Say; the hymenopterus genus Ilylafoma is probably attacked by the eulojihid 
Ilyperielcx hylafomae Ashm. (Ashmead, 1888, Canadian Ent., XX, p. lOo); while 
certain ( Idonata (Howard, 1901, In.seet Book, ji. 300) are also recorded to be hosts 
of egg-[)arasites. A spt-eies of “ Trirliogrammn” probably attacks Ilcmcrohiux 
(Howard, Ilymenojitera, in Stand. Nat. Hist., Boston, ]i. 511). 
The in.seet egg-parasites of the Americas are all hymenopterous, as far as we 
know definitely at the present time. The majority of them belong to the super- 
famikes Chaleidoidea (mo.stly the families Triehogrammidae and Alymaridae, and 
the following: — the family Torymidae < Podagrion only>; Eurytomidae < Rilev- 
ini, — Macrorileya and Neonlcyay; and the Eneyrtidae <Eupelminae, — Euprl- 
mus, Annxtahix\ Eneyrtinae, — Ooencyrfiix, J>inocarxixy and Proctotrypoidea 
(mostly the Seclioninae, comprising Plianurux, Tc'rnomux, Trixxolciix, Amdophagux, 
Proxarantha, Cahfclcia, Bnryronnx, Macrolrlria, Carux, Iladronotux, Idrix, and 
Scclio in the tribes Telenomini, Teleasini, and Seelionini respectively, and the sub-
