Sp. 6. Eciton smillima , n. s.

Worker. - Length 2 lines. Reddish yellow ; the antennae short and clavate ; head elongate, emarginate behind, the lateral angles acute : the metathorax having two longitudinal carinae, not produced at their apex ; legs shorter than in any of the other species, except E. crcissicornis , the first node of the abdomen having a minute acute spine beneath, at its base ; the second also having a very minute tooth, or spine, directed forwards: the entire insect very thinly sprinkled with pale glittering hairs.

This species approaches nearest to E. crassicornis ; but its flagellum is much more slender at the base, the head is more elongate, and the metathorax differently formed. Sent from Para, by Mr. H. W. Bates.
