208 Arthur M. Lea : 



T'rOG08ITIDAE. 



A specimen of this family, regarded by Mr. Blackburn as 

 probably belonging to a new genus near Trogosita, was taken 

 in a nest of Pheidole bos at Mount Barker (W. Australia). 

 Having but the one specimen and the cephalic appendages being 

 very small I have not considered it advisable to deal with it at 

 length. It is, however, a curious insect, with an outline and 

 general appearance much as in some of the narrow black species 

 of Adelotopus. 



COLYDIIDAE. 



Nepharis alata, Cast. 



{Hihetes thoracicus, King). 



Recorded by King from specimens " found in the nest of a 

 large Ijlack ant, under a stone at King G-eorge's Sound. Messrs. 

 Goudie and Davey have taken it in Victoria from nests of 

 1 7- idoniyrmex nitidus. 



Nepharis cost at a. King. 



Recorded by King as being '' found in the nest of a small red 

 ant living in wood and under bark of dead trees on the ground." 

 Messrs. Goudie and Davey have taken it in abundance from nests 

 of Iridomyrmev nitidus. 



Nepharis goudiei, Lea. 



Occurs in nests of Crematog aster laeviceps. 



Originally referred with some doubt to Nepharis. M. Grou- 

 velle, to whom a specimen was sent, wrote to me that he con- 

 sidered it generically distinct, but I will leave to him the task 

 of proposing a new genus for its reception. 



Nepharis serraticollis, n.sp. (Fig. 22.) 



Reddish-brown, margins and legs somewhat paler. Without 

 pubescence. 



Head flattened, somewhat dilated between antennae, apex 

 notched, a dentiform projection behind each eye, which is suuill 

 and lateral, with dense and coarse ^junctures, becoming smaller
