A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 137 
Female. Length 16°5 mm. 
_ Colour as on worker. Sculpture coarser, more rugose and the ground reticula- 
tion more conspicuous. Hair longer and more abundant. Pubescence brass yellow, 
oo very dense on gaster, finer and greyish-yellow on posterior half of post- 
petiole. 
Head slightly broader than long, External border of mandible concave, inner 
border convex, furnished with twelve sharp erect teeth, the second, fourth, sixth, 
eighth and tenth much longer and broader than the others. Scapes not extending 
to occipital border by fully their thickness. Parapsidal and mayrian furrows feebly 
indicated. Node one-fifth broader than long, very slightly broader behind than in 
front, broader than long, broadest at middle. Postpetiole one-fourth broader than 
long. First segment of gaster one-eighth broader than long. 
T have not seen the male but the following description by the 
late Dr. W. M. Wheeler is quoted for the sake of completeness : 
“The male (undescribed) measures about 11:5 mm. and is more opaque than 
the male of piliventris, with much more finely rugose head, thorax and petiole. The 
head is proportionally smaller than in piliventris or fulviculis, the thorax, petiole 
and postpetiole distinctly narrower and less robust, the postpetiole as long as broad 
and gradually narrowed anteriorly. The pubescence on the gaster is like that of 
the worker ; the wings are slightly smoky as in the males of piliventris and fulvicults, 
with yellowish-brown veins and darker brown pterostigma.” 
Habitat—Queensland : Mackay (type locality, G. Turner) ; Townsville (F. P. 
Dodd, G. F. Hill) ; Koah (W. M. Wheeler) ; Nanango (F. A. Cudmore) ; Burleigh 
Heads (Dr. C. P. Ledward) ; Brisbane (H. Hacker) ; Bribie Island (H. Hacker) ; 
Rockhampton (Godeffroy Museum). 
This species is variable in the formation of the teeth on the 
mandibles. At first sight it appears to belong to the mandibularis 
group; actually, however, it belongs to the teppert group and 
almost forms a connection between michaelseni and clarkt.
