Colony. Captured by Eev. G. Eogers in the papyraceous nest 

 of the ant Crematog aster peringueyi. 



This species is much larger, shorter, and thicker than A. syriacus, 

 Saulc, which is met from Bokhara, Mesopotamia, and Palestine as 

 far as Abyssinia. It would resemble more A. A-scoptdatics, Schf., 

 from Sumatra, but it is much less elongated and less parallel, the 

 punctuation on the head and prothorax is stronger, the antennse are 

 plainly longer, the fascicle of hairs on the hind margin of the elytra 

 is much less thick, and finally the tooth of the intermediate tibiae is 

 at least three times smaller. 



Gen. FUSTIGEEODES. 



fustigerodes gibbiventris, n. sp. 



Eobust and short, chestnut reddish lighter on the elytra ; head 

 and prothorax opaque, covei'ed with large ocellate punctures bearing 

 a short glandular seta, remainder of the body smooth and shiny ; 

 elytra with short squamose setae, abdomen glabrous. Head longer 

 than broad, sub-cylindrical, frons declivous and acuminate, epi- 

 stome dilated, large, straight on the sides, almost quadrately truncate 

 in front, tempora somewhat angular. Antennae longer than the 

 head and the prothorax taken together, joints 2 and 3 hardly longer 

 than wide, 2 quadrate, 3 slightly obconical, 4 large, slightly more 

 slender at the base, almost cylindrical, very slightly sinuate, truncate 

 at apex. Prothorax transverse, rounded on the sides, base slightly 

 angular, and having a weak furrow ending behind in a large fossa. 

 Elytra longer than broad, but little narrowed at the base with 

 shoulders i-ounded, and having 5 low, short carinules bearing each a 

 series of glandular squamae ; posterior external angle broadly truncate, 

 strongly reflexed and fasciculate opposite the abdominal prominence ; 

 posterior margm declivous, slightly arcuate. Abdomen as long as 

 but broader than the elyti-a, rounded on the sides and behind, very 

 strongly convex, almost gibbose, depressed on the sides with the 

 lateral margin narrow but projecting as a rounded fold and bearing 

 no fascicle of hairs ; at the base there is a very large and deep cavity 

 edged on each side near the lateral margin by a very strong, almost 

 quadrangular excrescence obliquely truncate at the tip, and bearing 

 along the elytra a brush of golden hairs, and a few setae above them. 

 Metasternum large, convex. Legs robust, short, little compressed ; 

 tibise thickening towards the apex, intermediate ones very slightly 

 arcuate and provided beneath, before the apex, with a small and 

 short spine. ^ .
