new A Ufa from Australia. 21 



occiput by nearly one-quarter its length, lunicular joints 

 shorter ; epinotal spines shorter, much shorter than their 

 distance apart at base, and directed more upward ; petiolar 

 node rising less abruptly from the peduncle. Colour usually 

 piiler and more y<'llowish than in loii(/ice/Js. 



The specimens in my collection from Mackay, Queensland, 

 named by Forel, agree in the main with the above, but the 

 head is as broad as long, very similar to that of poulton?, 

 but slightly narrower in front. The funicular joints are not 

 quite so long and thin as in the type of longiceps, but more 

 so than in jwulfoni The spines, besides being shorter than 

 in lonyicfjjs, are directed more upward and outward. The 

 sculpture, as Wheeler says, is less pronounced than in 

 longiceps. 



A. barbigu/a, Wheeler (/. c), is distinguished from longiceps 

 and pi/t/iia principally by the absence of spines, their place 

 being taken by small teeth, and by the shape of the head ; 

 from race poultoni by the shape of the head (which is of the 

 pijthia type) and the more scanty beard. 



Otherwise barbigula (according to the description and 

 figures) is very \\ke poultuni. 



An account of the appearance of the nests of poultoni is 

 given by Poulton in Ent. Mo. Mag. ? May, June 1922. 



Clark says that it nests mostly under stones, the actual 

 nest being underground with two or three small tunnels 

 leading downwards. 



Crematogaster perthensis, sp. n. 



^ . Length 3-3-1-0 mm. 



Varies in colour from dark castaneous brown, with the 

 thoiax less dark than head and gaster, and the apical half of 

 the latter nearly black, to castaneous, with the gaster dark 

 brown. The 5 major is the darkest in colour, and has a 

 black patch on the occiput. 



Head broader than long, as broad in front as behind, 

 sides feebly convex ; occipital border very feebly concave. 

 Mandibles with four teeth, clypeus depressed in front. 

 Eyes placed just behind middle of sides, scape barely extends 

 beyond occipital border. Antennal club 3-jointed, the 

 apical joint slightly longer than the two others together ; 

 joints 2-.^ of funiciilus as broad as long. 



Pronotum broad, the anterior angles rounded. Meso- 

 notum longer than wide, pro-mesonotal suture distinct, meso- 

 cpiuotal suture deep. 



Base of epinotum shorter than declivity, broader than
