bling that of this particular beetle ; some were taken from around the 

 roots of Thuja and maple trees and others from the roots or iris-plants. 

 They have been submitted to Ottawa for identification. Some have been 

 identified as being closely allied to our native Anomolas. and others are 

 in process of breeding to adults in order to determine their species. 

 There have also been other insects of minor importance. 



Insects infesting Stored Products. — Besides the insects that accompany 

 nursery stock from Japan and a few other parts of the Orient, there are 

 many species that infest the miscellaneous stored products imported to 

 this country. 



Some few years ago one might often notice along the wharves 

 [iroducts such as rice, corn, beans, peanuts, etc., just landed from Japan, 

 Chinft, Malaya Straits, or Australia, sim]3ly smothered with insects. 



It was a sickly sight sometimes to see a large consignment of rice 

 with thousands of larv;e of the Plodia interpunctella moth crawling over 

 the sacks or mats. A closer inspection of this writhing mass of larvae 

 might also disclose the presence of the Mediterranean flour-moth 

 ( Ephestia kuehniella) or the meal snout-moth (Pyralis farinalis). Then 

 by way of a little seasoning might be added the rice-weevil (Calandra 

 oryzas) and the flour-beetle (Tribolium confusum). Prowling among 

 these like a tiger in search of his prey would [jerhaps be seen the cadelle 

 (Tenebriodes mauritanicus ) . not ver}- particular whether he dines on a 

 good fat weevil or a grain of rice. There may still be other insects in 

 this miscellaneous assembly. Sometimes we notice the frivolous little 

 chalcid or other parasitic flies, and even the little flour-mites, Tyfogly- 

 phus. Consignments of the other products referred to. including wheat, 

 are lialjle to be infested with any or all ot the insects mentioned. 



One other lepidopter not referred to. is the Angoumois grain-moth, 

 which on some occasions has accompanied maize from Australia and 

 Manchuria, also peanuts from Japan. 



On one occasion a large consignment of maize arrived from the 

 Orient badly infested with weevil, Calandra oryza and granaria. The 

 little pests were so anxious to see Vancouver they climbed over each 

 other until they formed pyramids 6 inches high on to]) of the sacks. It 

 was very amusing to hear the remarks passed by the longshoremen 

 watching them. 



Within twelve hours after the maize had been landed on the dock 

 very few of the weevil were to be seen outside of the sacks. It is perhaps 

 needless to add the whole of this particular shipment was fumigated 

 sliortly after with carbon bisulphide, which ended the career of these 

 objectionable little immigrants. 



Pea and Bean ]Vccvil. — Other weevil of perhaps still more economic 

 importance are those of the Bruchus family, commonly referred to as pea 

 or bean weevil. It lias been necessary to fumigate large quantities of peas 

 and beans fmrn the Orient infested with tliuse ])articular insects. Bruchus 

 pisorum and obtectus.
