THE KNTOMOLOGTST. 335 



Genus Crematogaster. 



25. Cremntogaster pallidas^ Lowne. — Female less than a 

 line long, pale testaceous. Head and mesolhorax stuoolh. 

 Eyes large, ovate and black. Metathorax punctured, flattened 

 above, and armed with two short acute spines. First node of 

 the peduncle punctured and elongate ; second node globose 

 and smooth. Abdomen heart-shaped, with a iiiw pale stiff" 

 hairs scattered over it. Worker like the female, except that 

 the meso-, metathorax and peduncle are rugose, instead of 

 punctured. 



These ants excavate the earth under large stones. I found 

 two species of Pselaphus in one nest of this ant ; I gave them 

 to my friend Mr. Ramsey, of Ashfield, N.S. Wales, who was 

 engaged at the time in a Monograph on Australian Pselajjhida). 



26. C. picexis, Lowne. — Worker 1|- line long. Piceous. 

 Head nearly twice as broad as the thorax, almost globose 

 above, and slightly flattened posteriorly. Mesothorax ru- 

 gose, rounded and broad in front, narrowed behind, with its 

 disk concave. Metathorax narrowed in front, concave above, 

 flattened laterally, and armed with two stout acute spines. 

 First node of the peduncle, viewed in front, broad and 

 rounded at the base, and narrowed upwards, its apex obtuse. 

 Second node subglobose, with a deep longitudinal cleft above. 

 Abdomen heart-shaped, with pale stiff hairs scattered over it. 



I never found the nest of this insect. 



27. C. laviceps, Sm. — In small colonies under loose bark, 

 apparently making no nest, at least in spring. 



Genus Myemecia. 



28. Myrmecia gulosa, Fabr. — These ants throw up a large 

 conical dome of earth or sand, often a foot high, in light 

 soils, with the opening to the nest in the centre. 1 have ob- 

 served that they close the entrances in wet weather with 

 leaves. The pupa) are enclosed in cocoons, thus forming a 

 remarkable exception to the general character of the Myrmi- 

 cidae, which have usually naked pupae. The chambers in 

 which the pupae are placed are most often nearly two feet 

 below the surface of the ground. These ants are amongst 

 the most rapacious and numerous of Australian species: they 

 cliiub trees in vast numbers to attack the great Anajjlognathi, 

 which they pull down and bury alive in the earth, although 

 in point of bulk the beetles bear very much the same relation
