Aastrdlid II and Tasmaniav Colfoptera. 161 



loiiirer than wide, sides moderately rounded and widest almost 

 in exact middle ; with three subbasal foveae, of which the lateral 

 ones are rather large, and the median one rather s.mall, but 

 still conspicuous j punctures almost as on head. Elytra lightly 

 transverse, shoulders strongly the sides moderately rounded ; 

 dorsal striae deep and wide on basal half, subsutural striae 

 wide at base ; with small dense j»unctures. Abdomen scarcely 

 wider but considerably longer than elytra : second segment 

 with three strong ridges, of which the median one is somewhat 

 shorter and less pronounced than the others, third segment 

 wuth a fairly strong ridge towards each side, but scarcely ridged 

 along middle ; lower surface flattened along middle. M eta- 

 sternum flattened in middle, but excavated posteriorly. Legs 

 moderately long : four front tibiae obtusely spurred at apex. 

 Length 2| mm. 



Hah. — C^Hieensland : Townsville, from a nest of white ants 

 (H. J. Carter from F. P. Dodd). 



The dorsal ridges of abdomen and post ocular spines asso- 

 ciate this species with tertnitophila, which, however, is a much 

 larger and shining species, with very different antennae, etc. 

 In size and general appearance it is like i>onerae, but the head 

 antennae and abdomen are different. 



The space between the dorsal and subsutural striae on the 

 basal half of each elytron appears to be obtusely ridged. The 

 second and third ventral segments appear somewhat flattened 

 but not foveate, and as I can see no distinctly masculine features 

 the type is probably a female. 



Trne^i p]ioru>< fnrmirinus. Macl. 



I have seen specimens of this species from the nests of Ponera 

 lutea, from New South Wales, Victoria and West Australia. 

 ,It Avas described by Macleay as from the nests of Ectatomma 

 socialis, but his description of that ant reads as if it was 

 founded on P. hi tea, instead of on an Ectatonwia. 



Tniesipliorus terniitopliihis, Raffr. 

 Occurs in nests of Coptoterines raffrayi.
