1,266. Ordinary ants ^formicidae) belong to a different 

 order altogether from white-ants, the former coming under 

 Hymenoptera and the latter under Neuroptera. There are 

 several sub-families of the Formicidae, the Formica sacchari- 

 vora (Gondo-pimpra) y the Formica fuliginosa (the common 

 jet black ant) and the Camponotus sericeus (the ordinary 

 big black ant). The Camponutus smaragdinus (Kat-pimpra)^ 

 a greenish and large sized ant which lives on trees and makes 

 large sized nests of live leaves connected by a white web, 

 belongs to the sub-family Formicidae, while the ordinary 

 red house-ant (Diplorhoptrum molestum) belongs to the sub- 

 family Myrmicinae, which are armed with a sting. The For- 

 micidae though stingless often bite very sharply (e.g. Kat- 

 pimpra). Those who wish to study the interesting subject of 

 social insects, " Ants, Bees, and Wasps" should read the book 

 bearing this name written by Sir John Lubbock.

THE MANGO WE3VII, (CRYPTORHYNCHUS MANGIFERA). 



HpHIS weevil (Fig. 66^, d, d) which is very much larger in 

 size (about i of an inch being its length) than the granary 

 weevil, belongs to the family Curculionidae of the order Cole- 

 optera. It can be cut open from many ripe mangoes, special- 

 ly those hailing from Eastern Bengal, where it occurs very 

 plentifully. The weevils are black when they newly come out 

 of a fruit, but on drying they assume a rusty-brown colour. 

 The larvae are white, fat, with fleshy tubercles instead of legs. 

 As both larvae and pupae as well as imagoes can be got out
