.the outline; covers all of the dorsal surface smooth with no punctua- 
tions ; no marginal grooves ; no eyes ; no cervical grooves ; cervical 
•emargination deep ; festoons very short and poorly defined ; dorsal porose 
.areas just posterior of level of coxae IV, small, and widely separated. 
Ventral surface yellowish white, with alimentary canal sometimes showing 
through as white ; numerous tine punctuations and many short whitish 
hairs ; festoons much larger than on dorsal surface, and more sharply 
defined ; sexual orifice opposite coxae II ; sexual grooves very divergent 
behind coxae IV ; anus at the posterior quarter of the length ; anal groove 
.semi-circular, opening in front ; ano-marginal groove very faint ; stigmatic 
plates large, sub-triangular, a narrow postero-lateral prolongation. 
Rostrum colour of shield, long and slender ; base almost triangular on the 
'dorsal surface, sides rounded, rectangular on the ventral surface, wider than 
long ; hypostome spatulate, small denticles on the tip, then eight trans- 
verse rows, three teeth each on each half, the two outer teeth on each row 
very large and sharp, below these, and extending to the base, are indications 
of denticles, but represented only by crenulate creases ; mandibles 
(XT 7 , h) with inner apophysis of digit very thick and stout, recurved at 
the tip and bearing below the tip a paired or double transverse process with 
teeth projecting outward, outer apophysis with one large strong tooth 
bearing two very small teeth on its anterior edge- ; palpi elongate, more 
slender than in exornatum, excavated on inner edge ; article I very short ; 
article II constricted at its base, and twice as long as article III ; article IV 
papilliform, and in a pit on the antero-ventral part of article III. Legs 
short, but not so thick as in exornatum ; coxae rather short, almost con- 
tiguous,, each with a long sharp spine on the median part of the posterior 
•edge (XV, d) ; tarsi long and slender, sharply- attenuated at extremity, a 
single spur on the ventral surface. 
Female. — Body in a short, wide oval ; convex on the dorsal surface ; 
nnengorged 3 mm. long (without rostrum) by 2.5 mm. wide. Shield 
.reddish mahogany brown, clear, cordiform, the lateral angles at the anterior 
third of the length, the two postero-lateral margins concave, posterior angle 
Founded ; cervical grooves lacking ; cervical emargination deep ; punctua- 
tions very small, superficial, and few in number, located mostly in 
the anterior angles. Dorsal surface reddish yellow, grooves very 
superficial ; eleven marginal posterior festoons, very short ; dorsal 
porose areas very small, immediately posterior of shield. Ventral 
surface of same colour ; a few scattered white hairs ; sexual orifice 
opposite the interval between coxae II and III ; anus rather posterior ; 
anal groove in a wide semi-circle ; ano-marginal groove short ; posterior 
margin festooned as on the upper surface, only more strongly marked, 
stigmatic plates large, pale, comma-shaped. Rostrum narrow, long, base 
with sides rounded, fitted into emargination of shield ; porose areas 
elliptical longitudinally, small and far apart ; digit of mandibles with inner 
■apophysis rather anterior, transverse ; outer apophysis with three teeth 
progressively increasing ; hypostome wide, with three rows of teeth on 
•each half, six to seven teeth in each row, many small denticles on tip, and 
below them the large teeth, then crenulate to base ; palpi narrow. Legs 
of medium length, thick hairs rare and short ; coxae large, narrow, dark 
coloured, two long sharp spines on the posterior margin of coxae I, a single 
long, spine on median posterior margin of coxae IT, III, and IV ; tarsi 
three times as long as wide, those of first pair longer, and swollen at level
