of this species, which is often found associated with Creinastogaster 

 rufotesiacea and Iridoinyrmex detectus, especially in inhabited or de- 

 serted nests of the latter species, is "followed by a slightly painful 

 and persistent itch." 



3. Myrmecia nigriceps Mayr. 



Four typical workers. 



4. Myrmecia pyriformis F. Smith. 



Seven workers and two large larvae. This is the " black bull-ant " 

 and, according to Mr. Rawsey, is much less abundant in the mountains 

 of Victoria than the preceding species, "the red bull-ant." The 

 larvae resemble those of M. gulosa in ray collection and are shaped like 

 the larvae of Stigmatomma pallipes. They are fully 2 cm. long, non- 

 tuberculate and covered with short, sparse hairs.

5. Cremastogaster sordidula dispar Forel. 



Five workers, two females and three males which agree perfectly 

 with Forel's description. There is no trace of a longitudinal furrow 

 in the postpetiole of the worker. The specimens were " turned up 

 accidentally in a spadeful of earth. ' '

6. Tapinoma minutum Mayr. 



Several workers and two dealated females. The latter measure 

 4.5 mm. and are very slender. "Obtained from a mound i ft. by 

 1 14 ft- in diameter, at foot of gum-tree." 



7. Iridomyrmex detectus F. Smith. 



Six workers and two males. This beautifully iridescent species 

 seems to be common in all parts of Australia and does not vary to any 

 considerable extent. It builds large, sandy mounds, sometimes several 

 feet in diameter. Mr. Rawsey "^ counted 17 such mounds connected 

 on a hot day by one stream of ants," indicating that a single colony 

 extends over several nests. He states that the workers are harmless, 

 /. e., do not sting and that their bite is a " mere pinch." 



8. Iridomyrmex bicknelli Emery. 



Nine workers without noticeable differences from the typical form 

 of the species. Taken from nests "at roots of ' tussock ' (a poor, but 

 clumpy grass)."
