It is not necessary to repeat here the description of the 
worker of gilva since a very satisfactory account of this 
caste has already been given by WheeTer and Gaige (’20). 
It may be well, however, to mention in passing certain 
features which were not noted in their description. The 
greatest width of the head, which occurs approximately at 
the posterior third, is to the length as 3.7 : 4. The eyes 
consist of eight or nine poorly defined ommatidia which are 
partially obscured by overlying pubescence. The penulti- 
mate and antepenultimate joints of the funiculus are very 
slightly longer than broad and not, as has been stated, 
broader than long. Their true proportions are obscured 
in dry specimens by the erect hairs which they bear, but 
become apparent when the specimen is examined in a liquid 
mount. The ventral surface of the node of the petiole 
bears a rounded anterior lamella and a somewhat more flat- 
tened posterior lobe. 
Female . — Length 4.7-5. 2 mm. 
Head relatively broader than in the worker, its greatest 
width approximately equal to the length, the sides less 
evenly convex than in the worker, much narrower in the 
anterior half than in the posterior, the occipital angles 
well-marked, the occiput straight or at most very feebly 
concave. Mandibles large, their external border almost 
straight, except at the apical third, where it is feebly
