This species is certainly nearly related to C. brevicornis 

 Frogg., and it is only with hesitation that I have described 

 it as new. If, however, Froggatt's description is correct, 

 it cannot be identical with his species. But unfortunately 

 the illustration given by Froggatt contradiots in some 

 points his description. Thus, according to the description 

 of G. brevicornis Frogg., the wings are »slender, twice as long 

 as broad», but according to the fig. (6) Pl. XXXVI the wings 

 are more tan twice as long as broad. And the head of 

 the soldier is according to the text »twice as long as broad», 

 but according to the figure Pl. XXXVI, 6 a not so long. 

 The peculiar nervature of the wings makes it, however, very 

 probable that the two species are distinct. Also the colour 

 and other caracters differ. According to Froggatt, the tibise 

 in the imago of his species are »armed with five stout spines 

 at the apex». In my species I have not found more than 

 three. 



The species seems to be limited in its distribution to 

 the southern rain-forests. It lives in rotten logs, where I 

 found irregular ducts and galleries. The winged insect appear 

 in October. — Mt. Tambourine, S. Queensland.
