Tickler 



iMono/iai/iinus titillator I'abr. 



A lirownisli mottled cylindric l)cctle, about 'j iri< li lon^;, and with very long slender 

 antennat.', may he found in small numbers on pine trees in midsummer. The larvae 

 bore in the wood. 



This Ixaiitifiil little beetle was met with in very small numbers in iqoi 

 on l)oth while i)ln(; and lianl pine. This species is eviilently widely dis- 

 tributed, since its ranj^^e has been t,nven by l)r Horn as from Canada to the 

 state of W'ashinu^ton and smithwartl. It occiu's on pines in |inie and [iiK' 

 throughout the slate of New Jersey as recorded by l)r .Smith. This 

 insect was noticed brietl)- by Dr Harris, but he was not aware of its habits. 

 Mr b. C. Bowdiich has ascertained some inieresiin<,r facts reoardino- It. 



Life history and description. Mr b>o\vdiich records takin^j adidls under 

 the l)ark of yellow pines in Iinie, at which time a number were nearly reach- 

 to emerge, antl a week later he discovered no less than 80 beetles in one 

 tree in all stages of development, the largest being near the base. The 

 larvae ijore through the trunk, when it is less than 6 inches in diameter, 

 instead of working here and there on the surface of the wood. Wa states 

 that the larva feeds on the sapwood or inner bark till fall, when it turns and 

 bores outward, leaving its passage filled with chips, and forms a hiijernating 

 cell about 'i to ' ,,, inch beneath the bark, in which it com|iletes its trans- 

 formation during iIk; winter or even as late as the last of Jinic. Ihe grids 

 has l>een described by Mr Bowdiich as follows: 



The larva is a footless, \elIowish, white grub, more or less hairy, 

 cylindrical in shape, about 1 ^ „j inches long, and ? 20 of an inch in diameter. 

 The body including the head is made up of 14 segments, the last eight 

 of which have a kind of ridge on each side, covered with hairs longer 

 than those which are found on the rest of the body and which doid)tless 

 assist it in locomotion, the second segment next the head is flattened on 

 the upper side.
