Gahan (A. B.). New Reared Parasitic Hymenoptera with some Notes 

 on Synonymy. — Proc. U.S. National Mas., Washington, B.C., Iv, 

 no. 2261, 1919, pp. 113-128. 



The new Hymenopterous parasites dealt with in this paper 

 include : — Ichneumonidae : Phaeogenes (Centeterus) inep.ifrons, sp. n., 

 from Washington, D.C., a parasite of Cydia (Laspeyresia) molesta, 

 Busck ; Dacnusa iridicola, sp. n., from Pennsylvania, infesting Agromyza 

 laferella, Zett. , 14 females being reared from puparia of this European 

 fly infesting Iris. 



Braconidae : Trioxys cupressicola, sp. n., from California, reared 

 from an undescribed Aphid, Cerosipha sp., infesting Cupressus; Chelonus 

 (Chelonella) proteus, sp. n., from Maryland, reared from larvae of 

 Stagmatophora gleditschiaeella, Chamb., infesting the spines of the honey 

 locust tree {Gleditsia triacanthos) ; Bassus immaculatus, sp. n., from 

 Louisiana, reared in connection with Phthorimaea striatella, Murtf., 

 and possibly parasitic on that moth ; B. vsitatus, sp. n., from 

 Massachusetts, reared in cages containing Mineola vaccinii, Riley 

 (cranberry fruit-worm), and probably parasitic on it ; Apanteles 

 stagmatophorae, sp. n., from Maryland, reared from cocoons found in 

 burrows of the larvae of Stagmatophora gleditschiaeella, Chamb. ; 

 Orgilus dioryctriae, sp. n., from California, reared from Dioryctria 

 xanthaenobares, Dyar, on Pinus attenuata ; 0. mellipes, Say, reared 

 in Louisiana from Phthorimaea glochinella, Z. 



Chalcidoidea : Pseuderimerus mayetiolae, gen. et sp. n., from Cali- 

 fornia, reared from Mayetiola destructor, Say ; Heteroschema prima, 

 gen. et sp. n., and Habrocytus simillimus, sp. n., from Arizona, reared 

 from the pupa of Agromyza gibsoni, Mall., there being a possibility that 

 the latter may prove to be identical with H. languriae, Ashm., reared 

 from Languria mozardi, which like A. gibsoni is a stem-borer in lucerne 

 and related plants ; and Eutelus mayetiolae, sp. n., from California, 

 reared from puparia of Mayetiola destructor, Say.

 National Museum, Washington, B.C., Iv, no. 2271, 1919, pp. 295- 

 299. 



A few apparently new Ptinids reared in connection with the work 

 on insects infesting forest trees are described in order that the names 

 may be available for use in economic publications. They are : — 

 Ptinus huesanus, sp. n., from Florida, on Icthyomethia piscipula ; Oligo- 

 nierus arbuti, sp. n., from California, on dead manzanita {Arbutus sip.) ; 

 Ernobius conicola, sp. n., from California, reared from larvae feeding 

 on green and dry cones of Cupressus macrocarpa ; E. californicus, 

 sp. n., from California, reared from bark and outer wood of branches of 

 recently killed Pinus jeffreyi; E. champlaini, sp. n., from Colorado, 

 reared from dead limbs of Pinus fexilis.

 Agric, Washington, B.C., Bull. no. 778, 3rd May 1919, 8 pp., 2 figs. 



Neocerata {Basyneura) rhodophaga, Coq., causes considerable damage 

 to the flowers and leaf-buds of roses grown under glass. A list of 

 various roses attacked is given and all stages of this midge are described.
