In Europe they are known as wire-worms,and are often seriously injurious ; but in North America none ofthe species have as yet proved very troublesome. It is probablethat intelligent farm practice will be sufficient t(i control any ofthe species likely to become injurious with us. 33- AA ECONOMIC ENTOMOLOGY.

In the male the probos-cis contains a single lancet only,not fitted for puncturing animaltissues, and the antennae are plu-mose ; in the female a series offive slender, bristle-like lancetsforms an effective piercing struct-ure, and the antennae have thejoints furnished with a few bristlesonly. The wings are slender andscaly along the veins. The species are quite numerous,and while most of them are pestsof the first order, a few seem tofeed on other than animal more common species be-long to the genus Culex, in whichthe wings are unspotted, the palpi of the female are shorter thanthe beak, and the body is held parallel with the surface uponwhich the insects rest. The species of Anopheles are fewer innumber, but are of relatively greater economic importance,because they have been proved to be intermediate hosts for thepa
