enough, only in the drones, though it is the workers -which 

 frequent watery places (where the worm deposits its eggs) to 

 appease their thirst. The "Wax-moths, Gallerla cereana and 

 Achroia alvearia, do much harm by consuming the wax and 

 thus breaking down the cells, and hy filling the hive with 

 their webs.* 



The genus A2')is is indigenous in South America, though the 

 Honey-bee has been extensively introduced into the West In- 

 dies. Our Honej^-bee is replaced in the tropics by the stingless, 

 minute bees, which store up honey and live in far more numer- 

 ous colonies. The cells of 3IeUpona are hexagonal, nearly 

 approaching in regularity those of the Hive-bee, while the 

 honey-cells are irregular, much larger cavities, which hold about 

 one-half as much honey as a cell of the Humble-bee. From a 

 paper on the Brazilian Honey-bees, read by Mr. F. Smith be- 

 fore the Entomological Society of London, March, 1863, he 

 states that the Ifelijyonas are small insects, having icings shorter 

 than the abdomen, the latter being very convex and oblong ; 

 their mandibles never being dentate ; while the Trigonas haA-e 

 the wings more ample, and longer than the abdomen, which is 

 short, somewhat triangular, Avhile the mandibles are serrated, 

 denticulate, or sometimes edentate. The Meliponas are re- 

 stricted to the new world, while Trigona extends into Africa, 

 India, and Australasia. 



"All these bees are honey gatherers, but the honey collected 

 by the different species varies gi-eatly in quality : from the 

 nests of some it is excellent ; from others, worthless. The 

 honey of the species ' Mombuca ' is said to be black and sour, 

 the quality being dependent on species of flowers from which 

 the honey is collected. This great difference in the honey of 

 the various species is apparently confirmatory of the fact that 

 each species conflnes itself to particular flowers, never visiting 

 any other kind. The different relative length of the tongue in
