536 AUSTRALIAN TKRMITIDjE, 



Genus Mixotermes, Sterzel. 



This genus is founded upon the fossil wing of a termite from 

 Lugau. From the description given of the wing it is probably 

 allied to Cahtermes. 



Genus Hodotermes, Hagen. 



Bericht d. K. Akad. Berlin, 1853. 



Head large, circular, with the median suture behind branching 

 across towards the eyes; eyes oval, small, facets coarse, not pro- 

 jecting on the sides of the head; ocelli wanting : clypeus short, 

 convex; labrum small, shell-shaped; antennae a little longer than 

 the head, 21-27-jointed; jaws short, powerful, toothed. Pro- 

 thorax small, as large as the head, broader than long, saddle- 

 shaped. Wings small, four times as long as broad, twice the 

 length of the body. Tibite with five spines. Venation of the 

 wings similar to that of Calotermes, broad from the base. 

 Abdomen somewhat broader than the thorax, flattened on the 

 dorsal surface; anal appendages cone-shaped. 



In their habits the species resemble Calotermes. Seven species 

 have been described from Africa; four fossil species from Europe 

 and one from America. As yet I have found no Australian 

 species of this genus. 



The soldiers are remarkable for having true faceted eyes. Dr. 

 Sharp has figured the soldiers of a remarkable species, H. havi- 

 landi, from Africa, which move about in the sun without any 

 protection. 



Genus Porotermes, Hagen. 



Mon. Linn. Ent. xii. 1858. 



Head smaller than that of Ilodotermes; eyes small, facets fine; no 

 ocelli; venation of the wings similar but much finer. 



This is one of Hagen's subgenera, and was formed for three 

 species from Chili, S. America.
