Surface of body, especially of the gaster, shining. Man- 

 dibles coarsely and rather obliquely rugose, and coarsely 

 punctate along their borders. Head very finely and densely 

 longitudinally striate and sparsely punctate, posterior corners 

 a little smoother and more shining. Thorax, petiole, and post- 

 petiole very finely and densely punctate and feebly rugulos© 

 on the epinotum ; pronotum somewhat smoother and more 

 shining on the middle above. Gaster and legs glabrous, 

 shining, with fine, scattered, piligerous punctures.' Hairs 

 yellowish, coarse, bristly, rather long, erect, and moderately 

 abundant on the body ; shorter, oblique, and more numerous 

 on the legs. Gula without a psammophore. Ferruginous-red; 

 clypeus, frontal area, extreme anterior corners of the head, 

 and the mandibular teeth black : gaster and legs paler than the 

 remainder of the body, yellowish-red. 



Described from four specimens taken at Flat Rock Hole 

 in the Musgrave Ranges. 



This species is very peculiar in having large eyes and 

 two pairs of powerful teeth on the clypeus. The subgenus. 

 Jiolcomyrmex was supposed to be confined to North Africa, 

 Asia Minor, and the Indian Region till Viehmeyer recently 

 described from a worker minor a species (H. foreli) from 

 Killalpaninna, South Australia. Although I have seen only 

 major workers of H . whitei, I do not believe that they can be 

 co-specific with foreli, for this form has no teeth on the clypeus, 

 the gula bears a psammophore, the head is not sculptured 

 above and behind, and the colour is very different, being 

 described as chestnut-brown, with the head and gaster darker, 

 the segments of the latter bordered with yellow, etc. 77. 

 whitei is undoubtedly a harvesting ant, like its North African 

 and Indian congeners. The nests, of v/hich Captain White 

 secured an interesting photograph, are craters of a very pecu- 

 liar, chimney-like form. 



10. Crematogaster whitei, n. sp. 



Worker. — Length, 2 mm. 



Head slightly broader than long, convex above, sub- 

 rectangular, as broad in front as behind, with rather convex 

 sides, rounded posterior corners, and feebly excised posterior 

 border. Mandibles narrow, apparently 4-toothed. Clypeus 

 very convex, with nearly straight anterior margin. Frontal 

 area and groove absent ; frontal carinae very short. Eyes 

 moderately convex, their anterior orbits at the middle of the 

 sides of the head. Antennae 11-jointed; scapes reaching 

 a little beyond the posterior orbits ; funicular joints 2-7 small, 

 as broad as long ; club 2-jointed, its basal about half as long
