30 THE ENTOMOLOGIST. 
Pronotum constricted from the rest of the body, which is oval. 
Abdomen with short hairs on the anterior three-fourths, longer 
ones behind with shorter ones between. Cauda rounded to cone- 
shaped, very hirsute, hairs long. Pore-like, oval, flat tubercles at 
the sides. 
Legs rather long and thin, projecting; femora wider than the 
tibiz, tarsi of two segments, the basal one small, all the segments 
with fine short hairs. 
Length.—1°5 to 2°3 mm. 
Habitat.—Lambése, Batna, EK. Algeria. 
Time of Capture.— April 5th, 1918. 
Notes.—A large number taken in ants’ nests (Pherdole palli- 
dula, Nyl.), under the same stone as a nest of the termite 
(Leucotermes lucifugus, Ross), and three specimens from nest of 
Bothryomyrmex meridionalis by Mr. R. Gurney at the same time. 
The head varies somewhat in form; in some it is convex in 
front, in others flat, and some appear to have a median sulcus. 
The relative length of the antenne and proboscis also varies; in 
young forms they are about the same length, in older ones the 
antenne are considerably shorter than the proboscis. With 
regard to the connection with termites there is some doubt, for Mr. 
Buxton sends the following from his notebook :—‘‘ Ant, Aphis and 
Termite all under the same stone. The termites probably not 
in association, but ants and aphides actually in the same nest.”’ 
The termite has been determined by Holmgren as Leuco- 
termes lucifugus, Ross. 
Forda rotunda, nov. sp. 
Apterous viviparous female-——Dull white above, much domed ; 
flattened below, brown, the marked segments darkened apically. 
Antenne less than one-fourth the length of the body, thin, of five 
segments, the two basal ones short, about the same length, the basal 
one wider than the second, third segment the longest, slightly narrower 
than the second, about as long as the fourth and fifth together, the last 
two equal, a single round sensorium near the apex of the fourth and 
one large one and one or two small round ones at the base of the very 
short, blunt nail on the fifth, the last two segments brown, the rest 
yellowish, all the segments with fine short hairs. 
Eyes small and black, projecting from the side of the head. 
Vertex rounded or curved, nude. Proboscis short and _ thick, 
reaching just past the second cox, dark at the tip, with two sub- 
terminal sete; setaceous mandibles and maxill# rather short, the 
former spirally curled; proboscis bent under the body and more or 
less closely applied to it. A few hairs on the posterior of the body ; 
cauda very hirsute, hairs curved apically; no trace of segmentation 
on the white domed dorsum which has the appearance of white kid ; 
markedly segmented on the brown venter. 
Legs brown, first and second pairs very short, the femora thick 
and nearly as long as the tibie; tarsi of two segments, the same 
length in the first two pair of legs; third pair of legs longer, just
