our knowledge of the aphids on conifers, and varticularly lachnids, either as | 
regards classification.or distribution, is very meager. Recent discovery by 
bee men, that honey made from the honeydew of coccids and aphids produced on | 
pinejtrees is highly injurious to the bees, opened a new vista to the economic 
role of these insects. Consequently, it devolves upon forest entomologists and 
aphidologists to zive these insects more intensive consideration henceforth, 
Quick results are hizhly desirable and & knowledge of geographical and host. 
distribution is important, It is asked, therefore, that, whenever possible, 
entomolegists collect and send to this Bureau, addressed to the Forest’ Entomolos
