Chlamydopsis latipes, n. sp. 

 PI. xxv., fig. 14. 



Dark castaneous-brown, some parts (the metasternum and 

 abdonien quite) black. 



Head immersed in prothorax when at rest, face with 

 shallow reticulate punctures. Antennae moderately long ; 

 scape curved at base, greatly dilated towards apex, outer 

 portion with punctures as on face ; f unicle short, apparently 

 six-jointed ; club long and subcylindrical. Prothorax strongly 

 transverse, front margin lightly elevated behind head, then 

 with a strong oblique elevation to each side, sides scarcely 

 elevated and somewhat sinuous, with a subconical tubercle 

 in middle ; with dense reticulate punctures ; a narrow sub- 

 marginal line at base. Elytra about as wide as long; most of 

 surface shining and with minute (scarcely visible) punctures ; 

 epaulettes strongly raised and with punctures somewhat as 

 on prothorax, a strongly elevated process between each 

 epaulette and the suture, the process wide at the base, pointed 

 at the apex, and with a conspicuous fascicle of golden red 

 bristles, meeting a similar fascicle on a strong median 

 elevation, the fascicles crossing a deep transverse subbasal 

 impression, but between it and base a less depressed space with 

 rounded outlines; outer walls with strong striae. Prostemum 

 and mesosternum with punctures as on .pronotum ; metaster- 

 num shining, with a narrow median line; with small and not 

 very dense punctures. Abdomen with punctures as on 

 metasternum, pygidium and propygidium subopaque, and 

 with much denser punctures. Legs long ; femora densely 

 punctate, grooved on one side throughout their length ; tibiae 

 wide and compressed, grooved on lower edge to fit into femora, 

 with a shallow groove on inner side on the upper half for 

 reception of tarsi, the grooves with an irregular fringe of 

 setiferous granules, front ones dilating to about basal third, 

 where there is a small tooth, then slightly diminishing to 

 apex; the other tibiae wider and without the tooth, but 

 otherwise somewhat similar. Length, 3'6 mm.

 ants (Dolichoderes (Hypoclinea) scahridus, Mayr.t 6 )), J. S. 

 Clark. Type (unique),' I. 10675. 



With the reticulated pronotum and polished parts of 

 elytra as in the Tasmanian excavata, to which it is closer 

 than to any other known species, but much larger, and basal 

 parts of elytra, including the epaulettes and their clothing, 

 very different, tibiae even more dilated, etc. The tubercle on 

 the pronotum is quite distinct when viewed from the side,
