The genus Protodiaspis is discussed and a new genus, Ancepaspis, 

 is erected to which is referred Protodiaspis tridentata, Ferris (the type), 

 P. anoniala, Green, P. edenlata, Green, and an undescribed species 

 to be discussed in another paper,

 Collections. -CawatZ. Entom., London, Ont., lii, no. 2, February 1920,

Laeliusntilis, sp. n., is described. This Bethylid was found para- 

 sitising Dermestids infesting dried insects in a museum collection 

 in Virginia. 



The genus LaeliHS is well known to be parasitic on Dermestid 

 larvae and the following species have been recorded : — ^From U.S.A., 

 L. trogodermatis, Ashm., L. tricar inatits, Ashm., L. rvfipes, Ashm., 

 L. nigrijnlosus, Ashm., and L, fumipennis, Brues ; from France, 

 L. hipartitns, Kieff., L. tibiaUs, KieiT., and L. perrisi, Kieff. ; from 

 Italy, L.fnlvipes, Kieif., and L. anthrenivoriis, Tran.

Hypera nigrirostris is closely allied to H. variabilis (postica), both 

 being pests of clover, and the discovery of its parasites in North- 

 western America is thought worthy of record. 



This weevil, which has occurred in the east of Canada and U.S.A. 

 for many years, had not been known west of Minnesota before 1914. 

 Since that date it has been found widely distributed in the Pacific 

 North-west. Two Hymenopterous parasites also appeared in con- 

 siderable numbers, both being highly specialised for attacking Hypera 

 spp., viz : — Blathy plectes exigua, Grav., and Dibrachoides dynaster, 

 Forst. These para.sites are not found in the east, and it is unusual 

 for highly specialised parasites to become common so soon after the 

 appearance of the host. 



As H. nigrirostris is spreading from north to south in the Pacific 

 North-west, this seems to indicate that the weevil did not come from 

 the east, but rather that it is circumpolar in its range, or that it has 

 come from eastern Siberia by natural dissemination or accidental 

 introduction, probably by easy stages, such as would not eliminate 

 its parasites.

Experiments were made in the Rhine Province during 1917 to 

 ascertain the relative efficacy of the ordinary spray- nozzle and the 

 revolver sprayer in combating the second generation of the vine moths 

 {Clysia ambiguella and PoJychrosis botrana). A spray consisting of a 

 1 per cent. Bordeaux mixture with the addition of 3 lb. of tobacco 

 extract to every 20 gals, of spray was used, and the residts distinctly 

 show the greater value of the spray-nozzle, with which a given area was
