In this paper the author reviews the progress of applied entomology 

 in British Columbia in the past few years. The formation of the 

 Dominion Entomological Branch, the work of the various officials and 

 the chief insect pests investigated each year, are recorded.

The following pests have been found at various times infesting 

 nursery stock imported from Japan to British Columbia : Aspidiotits 

 perniciosus, A. forhesi, A. hederae (iierii), Chionaspis sp., Mytil- 

 aspis sp., Diaspis sp., Lecanium sp., and eggs of Porthetria dispar 

 found on the bark of arborvitae. Larvae of several beetles have been 

 found boring into the heartwood or feeding on the roots of trees or 

 plants, and a species of Prioxinae has occasionally been found in 

 roots of Wistaria, walnut and other trees. Larvae closely resembling 

 those of PopiUia japonica have been imported with iris and other 

 roots, together with other larvae allied to the native species of Anomala 

 [^R.A.E., A, ix, 583]. Insects infesting miscellaneous stored products 

 include : Plodia interpunctella, Ephestia kiihnieUa, Pyralis farinalis, 

 Calandra oryzae, C. granaria, TriboUnm confusnm, Tenebroides matiri- 

 tanicus, Bruchns pisormn, B. obtectus, Cylas formicarius, Phthorimaea 

 operculelia, Tyroglyphus sp. and the Angoumois grain moth (Sitotroga 

 cerealella).

Tent caterpillars [Malacosoma spp.] can be controlled to a large 

 extent by encouraging the growth of such evergreen and deciduous 

 trees as are not food-plants of these moths. A list of these is given.

The Syrphids dealt with include some 33 species belonging to 



16 genera. Of these, three species are of European origin, one is found 



also in Australia, and the remainder are indigenous, 14 being described 



as new. 



Keys are given to the genera of the Syrphin.ae, Eristalixae and 



MiLESiiNAE, and to the species of Cheilosia, Syrphus, Melanostoma, 



Platycheirus and Helophilus.

Of the five species of termites that occur in Porto Rico, Nasutiternies 



{Eiitermes) creolina, Banks, E. debilis, Heer, and Constrictotermes 



discolor, Banks, are rare and of little importance. The commonest
