CrsHMAN (R. A.). Eight New Species of reared Ichneumon-Flies, 

 with Notes on some other Species. — Separate, no. 2216, dated 

 9th August 1917, from Proc. U.S. Nat. Mus., Washington, D.G., 

 liii, pp. 457-469. 



The North American Ichneumonids dealt with in this paper include 

 Microcrypius osculatus, Pro v., bred as a primary parasite from the 

 larvae of a sawfly, Taxonus {Anietastegia) glabmtus, Fall. A key is 

 given to the North American species of the genus Bathytkrix, B. 

 tibialis, sp. n., bred from T. glabratus, being probably a secondary 

 parasite. Aenoplex nigrosoma, sp. n., was bred from the same host 

 and a key to the N. American species of this genus is given. 



Spilocryptus polychrosidis, sp. n., was bred from Polychrosis viteana, 

 Clem. ; Caenocryptus neivcomeri, sp. n., and Chaeretymma minutu, 

 sp. n., from Taxonus glabratus ; Scambus ephialtoides, sp. n., from 

 Rhyacionia {Evetria) sishiyouana ; Itoplectis obesus, sp. n., from 

 pupae of the fruit-tree leaf-roller [Cacoecia argyrosjyila] and of the 

 bud-moth [Eucosma ocellana] ; and Glypta evetriae, sp. n., from 

 Rhyacionia (Evetria) taxifoliella.

 Flies (Hymenoptera). — Separate, no. 2213, dated 10th August

The species dealt with in this paper include Tumidiscapus oophagus, 

 sp. n., reared from eggs of a grasshopper, Oxya velox, from Southern 

 India ; Abbella americana, sp. n., from Jassid eggs in Utah, four 

 females of Gonatocerus utahensis, sp. n., being reared with this species ; 

 and Trydymusaphidis, sp. n., reared from Lasioptera vitis in New York.

The mite, Eriophyes (Phytoptus) vitis, is now known to be the cause 

 of a disease of vine-leaves which was formerly considered to be cryp- 

 togamic. The four-legged larvae of this mite are reproductive and 

 give rise to several generations in the course of a summer. As winter 

 approaches, reproduction ceases and the mites hibernate under the 

 bark of the stock and the bud-scales, encyst and transform in the spring 

 into six-legged larvae, which develop into sexual, eight-legged adults, 

 and these oviposit on the young leaves. On the upjjer side of the leaves, 

 where the galls are found, only the four-legged forms are observed. 

 The damage is generally confined to the leaves, and is not very 

 important, but occasionally extends to the flowers, when it becomes 

 more serious.' The hot-water treatment of the vines for Sparganothis 

 pilleriana, decortication against Clysia ambiguellu, and whitewashing 

 against Coccids, destroy many of the hibernating larval mites. The 

 removal and burning of the first leaves attacked in the spring reduces 

 the numbers of succeeding generations, though sulphur treatment, 

 after clearing out the vines, checks the increase of E. vitis and the 

 development of galls more successfully than any other method. 

 Plunging the cuttings taken from infested vines into hot water is 

 also recommended.
