known June-bug or Dor-bug, Lachnosterna fusca Frohl.(Fig. 

 410, 411, larva; 412, side view of pupa), lives as a larva on 

 the roots of grass and is often turned up by the spade or 

 plough. It is then a large fleshy grub, very com- 

 monly met with, and is injurious to growing corn 

 and wheat. The pupa is found in its rude earth- 



en cocoon in May. The beetles are very injuri- \ 

 ous to the leaves of fruit trees. They are chest- : 

 nut brown, with yellowish hairs beneath, and 

 nearly an inch in length. There are several 

 smaller, closely allied species. Melolontha (Poly- Fi - 41 - 

 phylla) variolosa Harris differs in its enormously developed 

 six-jointed lamellate antennal club, that of the female being 

 much smaller. 



In Anomala the body is small, the an- 

 tennae nine-jointed, and the mandibles when 

 at rest do not project beyond the clypeus. 

 Such is Anomala varians Fabr., which is 

 very injurious to the vine in June and 

 July. Pelidnota punctata Linn, has similar 

 habits. It is oblong oval, very convex 

 Fig. 411. above, with dull brownish yellow elytra, 



with three large black dots on each side. It is often abun- 

 dant on grape-vines in July and August, and proves very 

 injurious. 



The Cotalpa lanigera Linn. (Fig. 413 ; a, larva) or the Gold- 

 smith beetle, is nearly an inch long, bright yellow, with long 

 white, woolly hairs beneath, where it is metallic 

 green. It often injures fruit and shade trees, and 

 Mr. S. Lockwood states that in the larva state it 

 destroys the roots of the strawberry plant. He 

 remarks that on the 16th of June a pair of Cotal- 

 pas coupled, and in the evening the female bur- 

 rowed beneath the dirt, reappearing the next 

 morning, having meanwhile laid at different 

 depths, and singly, fourteen white, long, oval eggs ; 

 on the 13th of July the larvae hatched, being five-sixteenths 

 of an inch long. (American Naturalist, vol. ii, p. 441.) 

 In Dynastes the labial palpi are inserted on the sides of the
