Notes on Euponera gilva

very thick and obtusely rounded. The ventral surface of 
the node bears posteriorly a swollen lobe and anteriorly a 
thin, evenly convex lamella. Seen from above the node is 
transverse, the apex, which is broader than the more ven- 
tral portions, is approximately twice as wide as thick. 
Gaster elliptical, the constriction between the first and sec- 
ond segments rather feeble. 
Color ferrugineous, the head and mandibles somewhat 
darker, the thorax marked with irregular areas of yellow, 
particularly on the pronotum and scutum ; petiole and abdo- 
men of a somewhat clearer tint, the posterior borders of 
the gastric segments with broad piceous bands. Antennae 
and legs brownish yellow. Cephalic punctures so closely 
approximated that the head appears to be covered with 
minute coriaceous rugulae, giving it an opaque texture 
which shows a dull sheen in certain lights. Thorax more 
shining, the punctures not so closely approximated, the 
epinotum somewhat more shining than the rest of the 
thorax. Petiole and abdomen strongly shining, the punc- 
tures about as numerous as those on the epinotum but very 
small. Mandibles highly glabrous, the punctures very 
sparse and minute. Head covered with moderately abun- 
dant, appressed pubescence, which becomes much longer and 
coarser on the frontal lobes. Pubescence on the thorax and 
petiole somewhat finer and sparser. Abdominal pubescence 
very abundant, longer, coarser and more erect than else- 
where. Erect hairs on the head sparse and short with the 
exception of one or two very long ones which are inserted 
at either side of the medium lobe of the clypeus. Those on 
the thorax longer and more abundant. Erect hairs on the 
gaster numerous, particularly at the edges of the posterior 
segments. Tarsi and funicular joints with numerous, short, 
stout, erect hairs. Wings grizzled, the veins and stigma 
yellow, the entire wing covered with numerous, fine, short, 
suberect hairs. 
Male . — Length 3.9 mm. 
Head subtrapezoidal, much narrowed behind, its greatest 
width (measured through the eyes) slightly greater than 
its length, occiput narrow, scarcely wider than the distance
