ten, I have found the latter genus to freely attack arboreal Del- 

 phacids as well as the graminivorous* species. The species found 

 most numerously stylopized in Arizona was Oncomctopia later- 

 alis in the nymphal stages (no. 2445) ; the second Jassid affected 

 by Halicfophagits was Ccratas,allia bigcloz'iac no. 2522; the Del- 

 phacid that yielded the parasite is a species of Sfolnuva no. 2523. 



EPIPYROPIDAE ( Lepidoptera) 



Mr. Koebele found Epipyrops barbcriaiia Dyar very common- 

 ly in Arizona affecting Issine. Amphiscepine, and Poecilopterine 

 leaf-hoppers. This species differs verv greatly in neuration from 

 the Australian forms, though like them superficially. In the hind 

 wings, veins la, ib and ic are well developed and veins 2-8 are 

 all present. In the Australian genera one of the veins 2-8 is 

 always absent and of these forms onlv Palaeopsychc has all the 

 veins from 1-12 in the forewings. The cocoon of this moth is 

 very similar to those of some Australian species, and has similar 

 erect processes or lamellae on the dorsum, these processes being 

 variable in number or form, as in the others. 



PIPUNCULIDAE (Diptera) 



In Arizona at Nogales a parasitized Jassid (no. 2469") was 

 found, from which a Pipitncitbis larva emerged and pupated on 

 the twenty-ninth of September and vielded the fly on the twenty- 

 ninth of October. It is a large snecies. quite resembling the .Aus- 

 tralian species of Div. T (TUdl. I. p. 130) in all characters, except 

 that the third antennal joint is hardly perceptibly produced at the 

 apex, though somewhat pointed there. A second species of Pi- 

 punculus (female) quite distinct from this and belonging to my 

 Section II of the .Australian species was bred from Arnphisccpa 

 bk'ittata, no. 2447. It differs from any of these in having the 

 third antennal joint only slightlv produced at the apex, though 

 acute. Koebele also procured other puparia of Pipunculidae, but 

 from these no flies have emerged. In my introductory remarks. 

 I have alreadv recorded the breeding in Honolulu of the Euro- 

 pean Vcrrallia aucta and I'illosa from German puparia. as well 

 as species of Pipunciilus, all from Jassids. Koebele found the 

 latter verv common in meadows in Germany ard many species 

 were obtained.
