pubescence. The head, coxae, and gaster with a few long hairs, other 
parts of body without them. 
Color black, apical four joints of antennae brown, tarsi brown. 
Described from one worker taken at Madeira-Mamoré R. R. Camp

The elongate pronotum which is only faintly depressed anteriorly, 
the shining black color throughout, the brown tarsi and tips of the 
antennae and the nearly entire absence of pilosity, distinguish D. 
apicalis from the other species of the genus. It approaches most 
-closely D. madeirensis from the same region, but differs from this in 
the shape of the head, the rounded sides of pronotum, the structure 
of the petiolar node, and in the extremely sparse pubescence and 
pilosity. 
223. Dendromyrmex branneri, sp. nov. 
Plate 6, fig. 47. 
Worker. Wength 8 mm. 
Head about one and one half times as long as broad, sides in front 
of eyes slightly convex, slightly broader at base of clypeus than in 
front of eyes, anterior corners angulate; occiput strongly contracted, 
seen from above with almost straight margin to a point a little over 
half the distance from eye to apex, then contracted into a narrow neck 
which is longer than broad, and has the posterior edge strongly re- 
flexed. _Clypeus slightly broader than long; sides straight, with a 
strong carina for entire length; anterior border truncate. Frontal 
area suboval in shape, with a longitudinal carina. Frontal laminae 
moderately elevated, approximating anteriorly. Mandibles rather 
slender, blade with five teeth. Antennae long and slender, scape 
extending a little beyond the mesoépinotal impression, joints of 
flagellum subequal in length, all longer than broad, the anterior ones 
somewhat the thickest. Eye small, very convex, situated at posterior 
fourth of head. Thorax long and slender, the width contained four 
times in the length. Prothorax broadest at anterior third, constricted 
in front, sides evenly rounded; in profile very slightly convex. Pro- 
mesonotal impression not deep. Mesonotum evenly rounded to near 
apex, where there is a strong transverse constriction; the sides from 
above strongly concave. Epinotum slightly over twice as long as 
broad, divided at anterior third by a broad transverse impression, 
which gives the profile the shape of a saddle; the declivity short,
