Characters of Genus. 
Cephalothorax longer than wide, high * sides and posterior angle 
sharply declivous. Pars cephalica sloping sharply forward, 
broad, square in front, and truncated. Clypeus hairy. Pars 
thoracica high, sides declivous, and deeply indented laterally. 
Eyes small ; posterior row less recurved than the anterior ; of 
the four comprising the anterior row, the median pair is smallest 
and much the closest together, whilst the series constituting the 
posterior row, are widely separated from each other, and equi- 
distant. 
Legs long, hairy. Relative lengths 1 = 2, 4, 3. 
Palpi short, hairy. 
Falces robust, hairy. 
Maxillce moderately long, outer angles constricted near their 
centre ; apices inclining inwards, obtuse, and not divergent. 
Labium coniform. 
Sternum oval, convex, truncated in front, obtuse behind. 
Abdomen oval. 
Saccodomus formivorus, sp. nov . 
(Plate xxx., figs. 2, 2a, 2b, 2c, 2d, 2c.) 
$ . Cephalothorax 2*7 mm. long, 2*2 mm. wide ; abdomen, 
4 mm. long, 3*7 mm. wide. 
Cephalothorax longer than wide, high, sparingly clothed with 
fine, hoary pubescence, dark brown, encircled with exception of 
clypeus, by a deep cream-coloured band. Pars cephalica dark 
brown, sloping forward, truncated in front, sides declivous. 
Clypeus dark brown, hairy. Pars thoracica dark brown, high, 
sloping forward, sides and posterior angle sharply declivous; 
there is also on each side and near the junction of the cephalic 
and thoracic segments, a long, deep depression. Marginal band 
broad, cream-coloured. 
Eyes small, black, arranged in two recurved rows of four each ; 
second row less recurved than the anterior; of the four comprising 
the anterior series, the median pair is the smallest, much the 
closest together and separated from each other by a space equal 
to about four times their individual diameter, but each lateral 
eye is removed from its neighbour by many times its individual 
diameter; the posterior series are slightly larger than their anterior 
lateral neighbours, widely separated from each other, but equi- 
distant or nearly so. 
Legs robust, hairy; anterior pairs dark brown, joints annulated 
white, but, judging from the specimens before me, these limbs are
