Psyche 
[September 
a - d) of A. serratulus (F. Smith). His description is quoted and 
translated below and his figures are copied as Text fig. 2. 
“Sono . . . subcilindriche, coi segmenti tutti distinti: sono prive 
di tubercoli o altre appendici e fornite di peli numerosi, brevi e 
semplici; non esistono peli forcuti, ritorti o uncinati ... II capo, 
benche piu piccolo e meno convesso che nelle Ponerinae e ben stac- 
cato dal tronco, e le mandibole sono lunghe, strette, sporgenti in 
avanti, fuori del labbro superiore; il loro margine interno e dentel- 
lato e off re alia base una forte dilatazione. Nelle mascelle, il cono 
piu vicino all’apice e semplice e allungato; al posto del l’altro cono, 
si trova una sporgenza ottusa, fornita di due piccoli tubercoli.” 
[Translation: Subcylindrical, with all segments distinct; no tub- 
ercles or other appendages ; furnished with numerous short simple 
hairs; no forked, twisted or uncinate hairs. The head, although 
smaller and less convex than in the Ponerinae is quite distinct from 
the body and the mandibles are long and narrow and project for- 
ward beyond the labrum; their medial borders are denticulate and 
strongly dilated at the base. The subapical cone of the maxillae is 
simple and elongate ; in place of the other cone there is an obtuse 
projection furnished with two small tubercles.] 
Discussion 
The ant larvae of the Subfamily Cerapachyinae constitute a 
well defined group which may be distinguished from the larvae of 
other subfamilies by the elongate, very slender, subcylindrical 
body which is rather strongly curved ventrally; by the large and 
prominent mouth parts ; by the paucity and shortness of the head 
hairs ; bv the rather feebly sclerotized mandibles, which are typically 
elongate and slender and have the medial border denticulate in part ; 
by the inconspicuousness of the labial and maxillary palps ; and by 
the absence (or scant development) of a trophorhinium.
