FAMILY LYMEXYLONIDAE 189 



Family LYMEXYLONIDAE. 



The mature beetles of this family are elongate and cylindrical, re- 

 sembling malacodermid beetles, with short serrate antennae and five-jointed 

 tarsi, the first and fifth joints of which are long. 



The larvae are very elongate and cylindrical, almost worm-like in 

 appearance, and white in colour, and tunnel in dead wood. 



The family is of doubtful importance in the forest at present. Some 

 years ago at Dehra Dun a log of wood which we considered to be Ano- 

 geissus latifolia was submitted to me by Mr. A. M. Caccia, M.V.O., of the 

 Indian Forest Service. This log was riddled with the circular tunnels of 

 lymexylonid larvae, the grubs being present in large numbers. Unfortu- 

 nately, during a prolonged absence of several months on tour, an accident 

 happened to the log and I secured no beetles from it, and I was thus 

 unable to procure the identification of the species. 



Both in Assam and Burma I have found lymexylonid grubs in the 

 wood of various dead trees, but I have never as yet bred beetles from them.
