THE INSECTS OF NEW JERSEY. 377 



of convenience, however, and because the change has not been generally 

 adopted in our lists, I have preferred to leave the species here. The 

 male only is winged, the female lives in the abdomen of some of our 

 paper-making wasps. 



XENOS Rossi. 



X. peckii Kirby. Occurs very rarely throughout the State in the abdo- 

 men of the species of "Polistes." 



Series RHYNCHOPHORA. 



The remaining families of the order belong to the so-called "snout- 

 beetles" or weevils, sometimes classed as a sub-order. The chief obvious 

 character of a great majority of the species is the elongated head or 

 snout, at the end of which the minute mouth parts are situated. In 

 some cases this snout is very much reduced; but in such types the tend- 

 ency is to a cylindrical form, and the pro-thorax has no lateral margin 

 or suture. Practically all the species are feeders upon vegetable tissue, 

 and many of them are injurious or even destructive to cultivated crops. 

 The families of this series are not easily distinguished except by the use 

 of rather obscure structural characters, and no definitions will be at- 

 tempted except in special instances e. g., the "Scolytidae." 



The larvas are white, very much wrinkled, stout, fleshy grubs, usually 

 without legs, with a yellowisTi head and a tendency to curl or assume the 

 position of a "white-grub." They also are vegetable feeders, attacking 

 plants in all parts, and many of them rank as first-class pests.
