ing sensilla or a short obtuse projection bearing sensilla; galea a 
slender conical projection bearing a single apical sensillum. Labium 
large and prominent; palp a cluster of three to five sensilla, some- 
times slightly elevated. Opening of sericteries mostly well de- 
veloped. Trophorhinium poorly developed or absent. 
Emery (1911) describes the larvae (under Section Prodorylinae 
of the Subfamily Ponerinae) as “uniformement poilues, sans tuber- 
cules piligeres” (p. 4) and “a peu pres cylindrique (comme la larve 
d’ Eciton) revetue de poils courts et san tubercules piligeres” (p. 5). 
Wheeler, 1903, pp. 208-209: “What light do these few observa- 
tions, together with those recorded in my previous paper, shed on 
the affinities of the Cerapachyi to the Ponerinae on the one hand and 
the Dorylinae on the other? . . . The following characters [of Cera- 
pachys augustae ] are common to both Dorylinae and Ponerinae: — 
1. The method of carrying the larvae is common to forms like Eciton 
and Leptogenys. 2. The larva is intermediate between that of Eciton 
and Stigmatomma. It is covered with shorter, less flexuous, and less 
abundant hairs than the latter and in these particulars resembles the 
larvae of Eciton.” 
Wheeler, 1920: “During the past year a study of ant-larvae, 
representing more than a hundred genera and many subgenera of all 
five subfamilies, has convinced me that Emery was right in 1899, 
when he regarded the Pseudomyrminae as constituting an indepen- 
dent subfamily. I am also of the opinion that the Cerapachyini 
should be removed from the Ponerinae and raised to the rank of 
an independent subfamily, between the Dorylinae and the Poner- 
inae” (p. 46). “A study of the larvae of the Cerapachyini shows 
that they are extremely like the larvae of the Dorylinae. This was 
noticed by Emery in his observations on the larva of Acanthostichus 
serratulus (1899). The mandibles are small, narrow, pointed and 
rather feebly chitinized, and I have failed to find a trophorhinium 
in either group. Apparently the young are fed only on soft food” 
(p. 50). On page 48 he states that the larvae of the Cerapachyinae 
are exceptional in not having a beautifully developed trophorhinium. 
Wheeler, 1922, p. 52: “The larvae are extremely like those of the 
Dorylinae; they are elongate and almost cylindrical, uniformly 
covered with short hairs, and without piliferous tubercles. The 
mandibles are small, narrow, pointed, and rather feebly chitinized, 
and I have failed to find a trophorhinium, or triturating organ in 
the mouth. Apparently the young are fed only on soft food.”
