THE JOINTED ANIMALS 



eggs along the sides of galleries which they burrow out under the bark; the larvae 

 when hatched make tracks at right angles to the mother galleries, and thus form

curious and characteristic patterns. 



The CerambytidcE or Longicorns 

 have in most cases a characteristic appear- 

 ance by which they may be easily recog- 

 nized, though, owing to a great variety in 

 their form and structure, the family as 

 a whole is not easily defined. Thus the 

 great length of the antennae to which 



these beetles owe their name is not always a distinguishing feature, for in many 



genera the antennae are much shorter than the 

 body. The Longicorns resemble the Rhyncho- 

 phora in having the first three joints of the tarsi 

 furnished underneath with a brush-like covering 

 of hairs, and the fourth joint very small and 

 hidden between the lobes of the third; but they 

 are distinguished from that tribe by the fact 

 that the epimera of the prothorax do not meet, 

 while the head, though sometimes produced 

 into a short muzzle, is never prolonged in the 

 form of a beak. The larvae all have a strong family likeness, and are quite unlike 

 those of the Chrysomelidas. They are of a dirty white or pale yellow color, with a 



APPLE-BLOSSOM WEEVIL.
