370 NATURAL SCIENCE. May 1894. 



flies and moths which do feed concludes Dr. Seitz's paper. He 

 mentions various observations of these insects drinking water, or dew 

 from leaves, and gives a list of the very unsavoury substances for 

 which they sometimes forsake their normal food — honey. Blood from 

 the wound of an animal is one of these not generally known. The 

 advantages taken by collectors of such aberrant tastes are sufficiently 

 familiar ; it is sad to remember that gorgeous butterflies can be lured 

 to capture by a bait of putrid meat, and moths by a mixture of 

 treacle and intoxicating drink.
