The shot hole borer, Anisandrus pyri (Peck), which has been referred to as the American representative of the European species A. dispar (Fab.) and from which according to Swame (1918) it is doubtfully distinct, has long been known in the eastern parts of Canada and the United States. This species has also been present for a number of years in the West where its distribution is apparently confined to the coast districts. As it has become particularly troublesome during recent years in British Columbia, and as published accounts of its occurrence in this province are very meagre, the following notes may be considered timely.

Much paler in the ground-color of the forewing than the typical form, the olive-gray shades being replaced by whitish; this is particularly evident between the reniform and apex of wing and along the inner margin. The broad blackish shading through central portion of wing from base to outer margin is heavy and a similar shade patch occurs on costa above the orbicular and reniform; the former is filled with white and in consequence is quite a prominent feature of the maculation, the latter is also largely white-filled with a slight ochreous shade in central portion and a strong black border-line on basal side. Secondaries almost pure white with faint traces of smoky terminal shading (somewhat more pronounced in the female) and indications of a smoky postmedian line in costal half of wing. Expanse 35 mm.

While studying the undetermined sawfly material in the Cornell University insect collection, the author discovered what he believed to be a species new to science in the genus Neurotoma. This belief was kindly confirmed by Dr. H. H. Ross who said that he likewise had a single specimen. Since that time four years ago, the author has collected this same species in considerable numbers and has also collected the larvae from the host plant which is Crataegus sp. It is therefore proposed to name it Neurotoma crataegi.

Palpi, vertex, and thorax, fawn colored. Frons with appressed white scales, overhung with long ochreous scales.

Male. Fore wing above, light fawn; finely and uniformly reticulate with purplish black, two or three reticulations widened at the costal third, with the spaces between these reticulations reflecting cupreous and causing this area to appear as an indistinct costal spot; a similar costal spot two-thirds from the base, and one at the middle near the edge of the posterior margin; a small oblong discal spot at the end of the cell.
