is especially striking. The clear cross lines which generally dis- 
tinguish the head of the Eutermes worker are with most of these 
females scarcely less distinct than with the workers. (Hagen 12, 
page 18 7 and at other places). The antennæ have fourteen joints, 
as those of the worker,-while the soldiers have but thirteen, and 
the winged animals have fifteen. The head could be taken for 
that of a worker if it were not for their little round faceted eyes, 
which, however, are scarcely raised above their surroundings, and 
are somewhat a slightly darker color. 
I have not observed ocelli. The prothorax resembles that of 
the worker—it has a saddle-formed depression, going cross-wise, 
which separates a forward flap, and this flap is very large with 
the worker, steep, turned upwards, and not deeply carved in the 
middle of its front edge. With the supplementary females it is 
only small, and was simply rounded off, and goes up slightly. The 
size of the forward lap changes, however, with some few samples, 
and it was reproduced by a small seam, and then the prothorax 
resembled that of the king. The wing beginnings take the whole 
lateral borders of the meso- and meta-thorax (Pl. XXXIV., A); 
mostly they are scarcely half so long as these body wings, 
broad and then triangular, horizontal to the outside directed 
projections of which the forward edge goes obliquely to the 
background; with very few samples (Pl. XXXIV., B) the wing 
beginnings are considerably longer; also the meso- and meta- 
thorax are in this case a great deal more strongly developed. The 
oblique to reverted wing beginnings cover the forward edge of the 
hinder ones. The belly shields are formed as with the winged 
females. The internal reproductive organs (Fig. 3) are nearly 
like those of the winged females, for the reason that they 
hold eggs. Every ovary seems to have about half a dozen, 
and the egg-tubes about a dozen, for every ovary (the number 
seems to be rather variable), and are placed in clusters, as with 
the winged females, on the end of a short oviduét, while with 
the full-grown queen every ovary forms a long tube, that in the 
whole length is covered thickly with extraordinary numbers of 
egg-tubes. The seed pocket and albumen glands have the usual
