Deen traced actually to grain is perhaps open to doubt ; but whether 

 that be so or not it is certain that we have in T. pallescentdla an 

 insect that might in favourable circumstances become a serious pest, 

 and one therefore whose life-history we should take every 

 opportunity of working out. The evident partiality of its larvae for 

 hair gives one visions of the seats of easy chairs and the mattresses 

 on our beds becoming masses of seething larvfe, untimely holes in 

 our carpets and mangy patches on our wives' furs, as among the 

 lesser troubles that might happen if the species once became really 

 abundant.
