ZOOLOGY OF FERNANDO NORONRA.

in the large workers it is red. Dr. Mayr records this species 
from New Granada, and it is probably widely distributed in 
South America. 
Under the wood of a Burra tree in the Sapate. 
25. Pheidole omniyora, n. sp. 
Soldier 4| millim. ; worker 2|-3 millim. in length. 
Soldier red, shining (abdomen darker), sparingly covered with 
raised white hairs. Head, without the mandibles, about as 
broad as long, finely and sparingly longitudinally striated above 
and in the middle, where it is depressed, behind ; sides gradually 
rounded behind the eyes. Mandibles very broad, hardly punc- 
tured, blackish at the base and tips. Scape of the antenna 
straight, gradually thickened beyond the middle, nearly one 
third of the length of the antennae. Second joint about three 
times as long as broad, joints 3-9 very slightly longer than broad, 
joint 10 much thicker and twice as long as broad, joint 11 rather 
shorter and thicker, and joint 12 forming a long pointed cone; 
the hair on the antennae is thicker and closer than on any other 
part of the body. Mesonotum with a hump on each side above, 
and finely punctured above ; metauotum, which is armed with two 
strong spines, more closely ; first node of the petiole with the 
spine somewhat truncated at the extremity ; second node fully 
twice as broad as the first, and with strongly projecting lateral 
angles ; abdomen finely punctured at the base. 
Worker similar, but smaller and generally darker, the autenme 
lighter ; the scape nearly as long as the remainder of the antennte, 
slightly curved, but hardly thickened, and the terminal joint 
thicker in proportion and less pointed than in the soldier. The 
spines on the metanotimi and on the first node of the petiole are 
much shorter, and the projecting sides of the second node are 
rounded off. 
This species much resembles Pheidole pusilla, Heer, iu size 
and general appearance, but differs widely in structure. 
This was exceedingly abundant in the houses, making nests in 
the earth between the bricks of the floor. It is very destructive, 
devouring all kinds of food, and even ate up the insects we 
captured, in the chip-boxes.
