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 

 tibiae, tarsi of two segments, the basal one small, all the segments 

 with fine short hairs. 



Length. — 1*5 to 2*3 mm. 



Habitat. — Lambese, Batna, E. Algeria. 



Time of Capture. — Aipiil 5th, 1913. 



Notes. — A large number taken in ants' nests {Pheidole palli- 

 dula, Nyl.), under the same stone as a nest of the termite 

 {Leiicotermes lucifugus, Eoss), 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 antennae and proboscis also varies ; in 

 young forms they are about the same length, in older ones the 

 antennae are considerably shorter than the proboscis. With 

 regard to the connection with termites there is some doul)t, 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 viviparoiLs fe^nale. — Dull white above, much domed ; 

 flattened below, brown, the marked segments darkened apically. 



Antennae 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 coxae, dark at the tip, with two sub- 

 terminal setffi ; setaceous mandibles and maxillae 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 tibiae ; tarsi of two segments, the same 

 length in the first two pair of legs ; third pair of legs longer, just
