120 SCHOOL ENTOMOLOGY 



mon leaf -eater is the Spotted Pelidnota. This is of a light 

 brown color with a few round black dots on the wing- 

 covers. It has much the shape of the June-bugs but is 

 larger. It sometimes injures grapes by eating the foliage. 

 Some very large beetles belong with the Scardbceidce. 

 Our largest species is the Rhinoceros Beetle. It is two 

 inches long, very stout bodied, olive-green and black. 



Two large horns are 

 borne by the males, one 

 on the head and one on 

 the thorax, and these 

 give the insect the ap- 

 pearance of a miniature 

 rhinoceros. Related 

 species in the West In- 

 V dies are six inches in 



length. 



FIG. 86. Typical " Lamellicorn " Lucanidce. The Stag- 



Larva (Lucanidve) . beetles compose the 



second family of the 



lamellicorns. They are a little more elongate and flat- 

 tened than most of the Scarabseids and their an- 

 tennal clubs are less compact. Their larvae are similar, 

 though usually larger, and are found in rotting wood. 

 Males of some species have very strongly developed man- 

 dibles and are often called Pinching-bugs. There are few 

 species and these are not important. 



74. Cerambycidae. These insects are called, as adults, 

 the Long-horned Wood-borers and as larvae, the Round-headed 

 Borers. The adults are slender, elongate beetles with an- 

 tennae unusually long, sometimes several times as long as 

 the bodies. They are among the most graceful and at- 

 tractive of the beetles. They have tarsi that are ap-
