black colour. The terminal joints of the funiculus are 
distinctly shorter than in pilosula. 
Myrmecia chaset, For., var. LUDLOWI, nov. 
%. Agrees with Forel’s description of chasei with the 
following differences :—Some specimens slightly smaller. 
Mandibles 3°5 mm. long, somewhat longer than the head 
(as long as head intype). Shoulders of pronotum apparently 
not so pronounced. Clypeus widely but not deeply emar- 
ginate. First node once and a half as broad as long (almost 
twice as broad as long in type), second node twice as broad 
as long (two and a half times as broad as long in type). Head 
densely reticulate between the rug, but on the thorax and 
first node the space between the rugze is more or less smooth 
andshining. The neck of the pronotum is transversely striate, 
the rest longitudinally, the striz slightly diverging in the 
direction of the base of the segment ; the second node is 
irregularly longitudinally rugose. There is a prominent 
central ridge on the first node. 
Colour similar, but there is a black patch on the lower 
half of the mesosternum, and a small one on the meta- 
sternum. 
The mandibles in their complete form have the typical 
long curved apical tooth of Myrmecia, sensu stricto, but in 
all the series, except two specimens, this tooth is completely 
worn away, leaving the mandibles with an oblique point. 
Ludlow, W.A. (Clark, no. 12). 
Type W.C.C. coll. 
This ant builds a cone-shaped earth-mound about one 
foot in height, with an entrance on the top about two inches 
in diameter, but there are also other entrances in the 
ground beyond the mound. It is an active and fierce 
insect.

funiculus, and tarsi brown.

half as broad as the first. 
var, perthensis. 
Dark brown; mandibles, antenne 
and legs red-brown; thorax and 
first node sometimes red-brown ; 
second node red-brown.

second. 
Second node not quite twice as 
broad as first.
