Nepltaris and other Ants' Nest Beetles. 375 



Hymenoptera. 



Forinicidae. 



Crematogaster laeviceps, Sm. 



(Plate XXVII., Fig. 2.) 



This is a small (3| mm. in length) reddish-brown ant, with a 

 black, heart-shaped abdomen, and the nietathorax with an acute 

 spine on each side. 



Iridomypmex nitidus, Mayr. 

 (Plate XXVIL, Figs. 1, I and 11.) 



This is a somewhat larger (5 inni. in length) ant, its meta- 

 thorax without spines and its abdomen oval. Mr. Goudie has 

 sent me winged forms of both the male and female, together with 

 some larvae and pupae. 



COLEOPTERA. 



Staphylinidae. 

 Dabra mypmecophila, Oil. 



A specimen from Mr. Goudie agrees very well with the de- 

 scription of this species, hitherto known only from Western 

 Australia, where it occurs also in ants' nests. 



Mr. Goudie has taken another and a very remarkable species 

 of Staphylinidae, apparently belonging to a new genus near 

 Bledius ; but as he has seen but one specimen, I prefer to leave 

 it undescribed at present. 



Pselaphidae. 



Articerus foptnumi, Hope. 



Readily distinguished by the antennae, which " are straight, 

 rather longer than the head, and somewhat narrowed in the 

 middle." It was originally described from Adelaide, but, be- 

 sides Birchip, occurs also in New South Wales.
