1923] Ants of the Genera Myopias and Acanthoponera 
185 
follows; Body ferruginous red; mandibles, clypeus, mesonotum 
and gaster brownish yellow; dorsal siudace of epinotum, the 
petiole and posterior borders of postpetiole and gastric segments 
dark brown; coxse and legs pale yellow, knees and tarsi reddish. 
Female. Length 3.2 mm. 
Wingless and ergatomorphic, differing from the worker only 
in its slightly larger size, in possessing small ocelli, in having the 
marginations of the epinotal declivity more rounded and less 
dentate above and in the larger abdomen, the postpetiole and 
first gastric segment especially being more Amluminous. The 
color of the body is also different, the pronotum being darker 
then the meso- and epinotum, the petiole, postpetiole and gaster 
reddish brown like the pronotum, with the posterior borders of 
the segments brownish yellow. The anterior is somewhat paler 
than the posterior half ot the head. 
Described from numerous workers and a single female which 
I took Sept. 5, 1914 from a single colony, comprising about 100 
individuals in the Waitakari Forest, near Auckland, New Zealand. 
The ants were nesting under a dead branch of one of the huge 
kaori trees {Agathis australis), which was lying on an exposed 
root of the tree from which it had fallen. When first disturbed 
the workers were quite active but on being touched curled up 
and “feigned death”. Similar behavior was observed by Hets- 
chko in the Brazilian A. dentinodis, according to Mayr. 
The single female, described above, was evidently the mother 
queen of the colony, which had a number of small larvae. These 
resembled the larvae of Ectatomma in being smooth, that is 
nontuberculate, and in being covered with dense, soft hairs. 
The subspecies is dedicated to Prof. H. B. Kirk of Victoria 
University, Wellington, the memory of whose kindness during 
my sojourn in New Zealand I shall always cherish. 
The occurence of a single ergatomorphic female as the mother 
queen of kirki is of interest, because so few females of Acantho- 
ponera have been taken, and because in the Neotropical denti- 
nodis, dolo and mucronata all the recorded individuals were of 
the typical winged type. But Emery in 1906 found two in- 
dividuals like the workers but with more voluminous abdomens 
among specimens of the Chilean carinifrons. One of these,.
