43 2 ARTICULATES : INSECTS. 



The Genus Stenocorus has the wing-covers narrow, and 

 notched or armed with two little thorns at the tip, and 

 the antennae very long. 



The Oak-Primer, 5. villostts, Fabr., is about half an 

 inch long, slender, dull brown sprinkled with gray spots, 

 scut el yellowish-white, the third and fourth joints of the 

 antennae tipped with a small spine. It lays its eggs in 

 July, placing each one in the joint of a leaf-stalk, near 

 the extremity of a branch. As soon as the larva is 

 hatched, it penetrates to the pith, and then moves to- 

 wards the body of the tree, devouring the pith as it goes. 

 At the close of the summer, it has moved several inches ; 

 and now, having arrived at its full growth, it cuts out all 

 the wood at the lower extremity of its burrow, leaving 

 only the bark to sustain the branch ; then, retiring a little, 

 it stops up the downward end of its burrow, and awaits 

 the fall of the branch, which takes place during the first 

 strong wind. Branches an inch in diameter and several 

 feet in length are thus cut off. The larva goes into the 

 pupa state in the spring, and comes out a beetle in June. 

 The Genus Clytus contains capricorn-beetles which are 

 beautifully colored with black and yellow. They are seen 

 in great numbers upon flowers and upon the trunks of 

 the locust-trees in the early autumn. 



The Painted Clytus, C.flexuosus, Fabr., is about three 

 Fig. 326. quarters of an inch long. The Beautiful Cly- 

 tus, C. spec^os^is ) Say, is an inch long, and lays 

 its eggs on the trunk of the maple in July and 

 August. It is the largest known Clytus. 



The Genus Lamia contains the Tickler, L. 

 titillator, Fabr., which is about an inch and a 

 quarter in length, brownish, mottled with spots

twice as long as the body. It gets its name from its habit 

 of gently touching with the tips of its long antennae the 

 surface over which it walks.
