171. Dolichoderus (Hypoclinea) lutosus (F. Smith). 
Plate 3, fig. 20. 
Several colonies, nesting beneath stones were found at Natal and 
Baixa Verde. Those from the latter locality are small in size (length 
3.5 mm.) and are evidently from an incipient colony. A figure of the 
worker is given in Plate 3, fig. 20. 
Female. Length 6 mm. 
Ocelli very small, arranged in an equilateral triangle. Base of 
epinotum shorter than declivity. 
Color similar to that of worker but more iradbrineddt First three 
gastric segments with a median longitudinal fuscous line; apex of 
first segment with a narrow transverse fuscous band; apical two thirds 
of the second and border of the third segments fuscous. Wings 
hyaline; veins and stigma brown. 
Male. Length 3.75 mm. 
Head, excluding the mandibles, as long as broad, convex behind 
and at sides, with large, moderately convex eyes, which occupy 
about half the sides. Frontal area distinct, triangular; carinae fine. 
Clypeus convex at middle, broadly concave at middle of anterior 
border. Mandibles well developed, stout, as long as the distance 
from their base to the eye, blade with several fine teeth anteriorly. 
Vertex elevated into a broad tubercle on which the large ocelli are 
located; in front of this, beneath the median ocellus the front has a 
deep, triangular impression. Antennae short, extending to base of 
gaster; first funicular joint a third the length of the second. Thorax 
robust, mesonotum evenly rounded above, with feeble Mayrian fur- 
rows. Epinotum short, base rounded, declivity flat, the two surfaces 
separated by an obtuse angle. Petiole twice as high as thick, anterior 
surface rounded, posteriorly nearly flat, the apex narrowly, thickly 
margined. Gaster similar to that of worker, but flattened above. 
Genitalia small. Hypopygium small, broadly triangular. Cerci 
very small. Legs slender. Wings long and narrow. 
Body shining, very minutely punctate. Mandibles punctate, with 
several long hairs. Body without long hairs. Thorax and abdomen 
with sparse, regular, very minute scale-like white hairs. Funiculus 
densely pubescent. 
Color dark fuscous, gastric segments at base lighter.
