tire head reddish yellow, with the exception of a median 
spot on the vertex. 
The single mermithergate of C. piperatus was taken De- 
cember 14, 1931, from a small colony at the Creel on Mt. 
Kosciusko on the same hillside as the eight consobrinus 
mermithergates described above. It measures 10.3 mm. 
and is therefore somewhat longer than the normal maxima. 
The head measures 1.6 mm., the gaster, containing a well- 
developed Mermis, 5.3 mm. The general aspect of the speci- 
men is that of a huge minima, but the head is distinctly 
broader in proportion to its length and the thorax and 
petiole are those of a maxima. The thorax has a distinct 
metathoracic sclerite and the epinotum is high, with a per- 
ceptible angle between the base and declivity. The petiolar 
node is robust, with a feebly notched superior border. The 
anterior portion of the head approaches that of the maxima 
in having a more uneven and more coarsely punctate sur- 
face than the minima. The color, too, is like that of the 
maxima, since the mesonotum and posterior portion of the 
epinotum are dark brown. The gaster is very pale even 
at the tip ; the brown spots are pronounced on the pronotum, 
but pale and scattered on the gaster. Except for the smaller 
and narrower head, the specimen might be said to resemble 
a media, but this subcaste, as previously stated, does not 
seem to exist in claripes. 
Camponotus ( Myrmothrix ) abdominalis Fabr. 
subsp. stercorarius Forel (Fig. 3) 
C. abdominalis is a common and very aggressive, neo- 
tropical ant, quite as variable and widely distributed as the 
two Australian species above noticed. It ranges from 
southern Florida and Texas to southern Brazil as a “For- 
menkreis” embracing no less than 13 subspecies and 5 va- 
rieties. Most of these forms nest in moderately large col- 
onies in dead branches or rotten wood, but some of them 
live, at least temporarily, in the ground under stones. This 
is true of the subspecies floridensis Buckley of Florida and 
the Central American and Mexican stercorarius. Forel 
(1884) long ago described the nesting habits of the latter
