the names, Pimpla annulipes, Brulle, P. inquisitor, Say, and P. inquisi- 

 toriella, D.-T. Careful study of specimens and literature however 

 shows that these names as usually applied are erroneous, and the 

 following synonymy must be employed : — Pimplidea aeqiialis, Prov. 

 {Pimpla annulipes, auct., nee Brulle, P. eonquisitor var. rufuscula, 

 Davis) ; Pimplidea tenuieornis. Cress. {Meniscus nmrginatus, Prov., 

 M. ashmeadi, Prov.), M. marginatus and M. ashmeadi, having been 

 previously treated as synonyms of P. annulipes ; Epiurus inquisitoriella 

 D.-T., {Pimpla {Iseropus) inquisitor, Say) ; Iseropus coelehs, Walsh 

 {Ichtieumon inquisitor var. a. Say, Bassus cylindricus, Prov., Pimpla 

 {Itoplectis) orgyiae, Ashm., Pimpla bruneifrons, Vier.).

Microbracon cephi, sp. n., here described, is an important parasite 

 of the western grass-stem sawfly, Cephus cinctus. The type was 

 reared from a larva of C. cinctus infesting stems of Agropyron, other 

 specimens being from the same host in stems of Elymus and Bromus 

 in North Dakota and in stems of Elymus canadensis in Manitoba.

One of the new flies described in this paper is a Chloropid, Madiza

In November 1917, Anthonomus grandis var. ihurberiae was found 

 heavily infesting a wild littoral species of cotton, Gossypium davidsoni, 

 in Mexico. This plant, which is a vigorous shrub of dense habit, 

 growing on moist sand dunes almost at the ocean's edge, was in an 

 advanced fruiting condition and the bolls were harbouring adult 

 weevils in abundance. This shrub occurs extensively throughout the 

 southern part of Lower California at elevations varying from sea 

 level to 1,400 feet, and as far northward on the east shore of the 

 GuLf of California as Guaymas.
