moderate in length and broadly dilated. Tlianasimus differs 

 in the body being hairy, while the posterior tarsi are longer 

 and scarcely dilated. The long narrow slender pink larva' can 

 be found under the bark of dead pine trees where the}' probably 

 prey upon the lame of llylurgus and Hylobius. The larva' 

 of Clems are of a beautiful red color. The European Clentx 

 alv<M)-ins infests the nests of the Mason-bees, Osmia and Meg- 

 achile. -'The larva when hatched, first devours the grub of 

 the bee in the cell in which it is born and then proceeds from 

 cell to cell, preying upon the inhabitant of each until arrived 

 at maturity. It is in this situation, also, that it undergoes its 

 changes in a sm;ill cocoon, which it has previously constructed, 

 making its escape from the nest in the beetle state, where the 

 hardness of its covering sufficiently defends it from the stings 

 of the bees." (Westwoocl.) 



LVMKXVI.ID.I: Leach. This small group, chiefly interesting 

 as containing a genus which h:is proved of great mischief to 

 the ship timber of Europe, from its boring habits, is distin- 

 guished by the head being bent down and 

 narrowed behind ; by the usually very large 

 eyes, the two ciliate lobes of the maxillae, 

 the palpi of which are stout, four-jointed, 

 and in the male very large and nabellate, 

 while the mandibles are short and obtusely 

 bidentate. The body is long and narrow, '''- 4:! ^- 



with slender legs. The genus Lynwilon has live abdominal 

 segments. The larva is very long and slender, with the first 

 thoracic segment dilated into a large hood, while the terminal 

 ring is produced into a large obtuse lobe. In Europe it, 

 greatly injures oak trees and ship timber, but our species 

 (Lymexylon sericeum Harris, Eig. 438, and antenna', legs and 

 palpi) is too rare to be of any harm at present. 



CITPESITI/E Lacordaire. Leconte states that "the affinities 

 of this family are very obscure ; in the form and insertion of 

 the antenna? it is similar to the first genera of the next family, 

 but other characters, such as the form of the coxa' and the re- 

 tractility of the legs, are at variance. The body is covered
