placed them in four sub-families, based on the wing structure, placing 

 the Calofermitince as the first division. 



Desneux, in his paper, " Apropos de la Phylogenic des Termitides," 

 published in the "Annals of the Societe Entomologique de Belgique," 

 last year (1904), makes some critical remarks upon my classification, in 

 which he places the sub-family Termitince first, with the Rhinotermitincc 

 as a group with them, and the Ilodotermince as a group of the Caloter- 

 mitince, forming a third sub-family, Mastotermitince to contain my 

 genus Mastofermes. If, however, we take the robust termites as those 

 most closely allied to the cockroaches, we must commence with Masto- 

 termes, following up with Calotermes, with the more feeble-winged Te/- 

 mitince connecting them with the Emhiidce. 



Wasmann lias created a new sub-genus (Coptotermes francatus) 

 for a termite in Madagascar, which has the front of the head furnished 

 with an opening above the jaws, from which it can discharge a protective 

 fluid when molested; this appears to be a valid distinction worthy of 

 generic rank, and will include two of my species, and a third Wasmann 

 has since described from West Australia. 



In adopting Desneaux's new sub-family for my thick-winged termite 

 from Port Darwin, and thus taking it out of the Calofermitince, I still 

 retain my two other sub-families, and the Ehinotermes, while coming after 

 the Calotermes, are very easily seperated by their wing structure. 



The following is the order in which I would place them: — 



ORDER-ORTHOPTERA.

The head large, nearly as long as broad, flattened on the summit; 

 eyes large, projecting; ocelli prominent, with antennae composed of
