surface often swollen, greenish grey, with, the marginal chitinons, reinforce- 
ments brownish, separated by grooves and corresponding to the dorsal 
festoons ; sexual orifice opposite coxae II, wide, anterior valve chitinons, 
.sexual grooves at first almost parallel, then very divergent between coxae 
IV and the anus ; anus near the posterior quarter ; hairs very short on all 
the ventral surface ; stigmatic plates white, with chestnut margins tri- 
angular with rounded angles, the poster o- lateral angles well marked. 
Rostrum (A III, a) 2 mm. long ; base concave on its posterior margin, lateral 
margin convex ; mandibles {XII, h) with inner apophysis sub-terminal, 
transverse, festooned in three points, one median, and two lateral, of which 
the inner is elongate transversely outer apophysis with two teeth, the 
terminal small, the other very strong ; hypostome a little spatulate, numerous 
denticles on the tip, followed by three then by four rows of teeth on each 
half, which gradually diminish and become squamiform on the basilar half 
of the organ ; palpi 1.4 mm. long • article I with its ventral surface twice 
as long as the dorsal and prolonged on the inner edge by an obtuse point 
over article II ; article II twice as long as article III, and prolonged on its 
extero-dorsal base into a flat point over the first ; hairs rather long on the 
two edges of the convex surface of articles II and III. Legs thick, reddish 
brown ; coxae contiguous {XII, l) ; coxae I divided into two blunt spines ; 
the outer longer ; coxae IV with a single strong spine ; coxae II and III 
unarmed ; the other articles, save the tarsi, ringed with whitish colour on 
their distal extremities ; tarsi I at least four . times as long as wide, 
.suddenly attenuated near the extremity ; tarsi II, III, and IV at least three 
times as long as wide, with two strong consecutive spines ; caruncle reach- 
ing scarcely to the middle of the length of the claws ; short hairs on all the 
articles. 
Female. — Body almost the same form as in the male, relatively 
narrower, dimensions ordinarily a little larger, even when young ; colour 
generally deep greenish brown, except the shield, the rostrum, and the 
legs, which are deep reddish brown. Shield triangular in its posterior 
two thirds, with posterior angle rounded, a little wider (3 mm.) than long, 
deep brown, sometimes with a reflection or spot of greenish metallic red in 
the centre or near the posterior angle and the origin of the cervical 
grooves ; cervical grooves deep in front, prolonged almost to the. posterior 
margin ; punctuations deep, large, unequal, very numerous, often con- 
tiguous ; eyes near the anterior quarter, similar to those of the male. 
Dorsal surface unicoloured, deep green, a marginal groove situated ai: a 
nearly uniform distance from the margin, forming the anterior margin of 
the eleven posterior festoons, which are scarcely longer than wide. A 
median groove, extending from the median festoon to a certain distance 
from the shield ; two lateral grooves, concave outward, beginning at the 
space between the penultimate and antepenultimate festoons ; punctuations 
deep, equal, scattered over all the surface. Ventral surface deep green, 
similar to that of the male ; sexual orifice narrower ; marginal festoons 
not chitinous ; an ano-marginal groove ; stigmatic plates larger. Rostrum 
■{XII, lb) 2.6 mm. long, similar to that of the male, except in the following 
particulars : porose areas present and large, oval digit of mandibles with 
inner apophysis bicuspid, base swollen ; outer apophysis with three teeth, 
the two posterior strong. Legs rather longer, hairs rather long ; spine of 
coxae IV reduced to a flat tuberosity ; the penultimate tarsal spine 
attenuated, often almost effaced. 
The fecundated and engorged female can reach the largest dimensions 
of the family (24 mm. long by 15 mm. wide, and almost as thick). At first
