separated by deep grooves, punctuations unequal, the large ones very large 
and deep, in the marginal grooves they may be contiguous or almost so,, 
they prolong the marginal groove anteriorly beyond the eyes by two lines of 
punctures, the remainder are arranged in four more or less regular, longi- 
tudinal lines in the middle area of the shield, the small punctures are evenly 
distributed over the shield, but distant from each other, and usually so fine- 
and shallow as to be almost invisible ; three posterior longitudinal grooves,, 
very superficial ; dorsal porose areas present at anterior quarter of length 
of shield. Ventral surface yellowish or brownish in colour ; a few 
punctures ; glabrous or with thinly scattered hairs ; sexual orifice opposite 
the anterior edge of coxae II, sexual grooves diverging behind; anus 
chestnut brown in colour, opposite the middle of the anal plates, which are- 
triangular, with the inner edge concave, outer edge convex, and posterior 
edge convex {IX, f) ; a chitinous point forms the accessory anal 
plates ; eleven festoons present, the median one often prolonged in 
rectangular appendage ; stigmatic plates elongate, comma-shaped. 
Rostrum with base wider than long ; depressed in middle, the 
posterior angles*, prominent, lateral angles prominent at the 
anterior third of the length ; mandibles {X, i) with process of 
inner apophysis transverse and bidentate, outer apophysis bidentate, the 
anterior tooth small ; hypostome with six rows of teeth ; palpi longer than 
wide, article II longer than article III, its inner dorsal margin longer than 
the outer ; seven to nine hairs on the inner ventral margin ; article I also- 
with a ventral projection; article III wider than long. Legs reddish 
brown in colour, strong ; articles somewhat flattened dorso-ventrally ; 
tarsi short. 
Female. — -Body oval,, a little wider behind than in front, may reach a 
length of 12 mm. by 8..0 mm. wide ; colour brownish, with lighter colour 
marking the furrows and festoons. Shield (X, f) scarcely or not longer than, 
wide ; very dark, almost black in colour ; shining ; sides rounded or only 
slightly angular ; punctuations numerous, unequal, large punctuations in 
middle and marginal areas ; marginal grooves formed of a row of large pits, 
small pits evenly distributed,- but usually so small and superficial as 
to be almost invisible ; cervical grooves almost reach the posterior margin 
where they nearly join the marginal grooves ; eyes shiny, flat, pale yellow,, 
or often reddish in preserved specimens, a little behind the middle of the- 
length of the shield. Dorsal surface of the abdomen lightly shagreened, 
in young individuals, punctuations large and occupied by whitish hairs ;: 
dorsal porose areas just posterior of the shield ; marginal grooves at some 
distance from the margin, occupied by punctuations and hairs ; four 
anterior grooves, the outer ones close to the corresponding marginal grooves 
and very long ; three posterior grooves, the median longer ; festoons well 
marked, elongate ; when fully engorged the grooves and festoons are still 
faintly marked, usually by lines of a grey colour. Ventral surface of a 
uniform greyish or brownish colour, lighter than the dorsal surface ; 
glabrous or with a few hairs ; punctuations few and scattered ; posterior 
festoons very apparent' ; sexual orifice opposite first inter-coxal space, 
sexual grooves diverging very rapidly behind coxae IY ; anal groove well 
marked ; ano-marginal groove present ; stigmatic plates short, comma- 
shaped, with prolongations very short. Rostrum with base shorter than in 
male ; mandibles (X, i) with process of inner apophysis bearing four teeth, 
outer apophysis tridentate ; hypostome as in male, but longer ; palpi similar 
to those of the male, only longer. Legs similar to those of the male, except 
that they are longer and more slender ; tarsi relatively long.
