rostrum, to the caudal' extremity of the prolongation) 3.9 mm. to 4.3 mm. ; 
width 1.9 mm. to 2.3 mm. bmetd (Vii, b) a little convex, narrow, dark 
brown, brilliant, not covering all the dorsal surface, heaving free a narrow 
margin on each side, which is finety striated, and is prolonged behind the 
regularly rounded .border of the shield, by the caudal appendix ; in front 
a deep emargination to receive the contraction of the rostrum • a few 
very short hairs behind the surface corresponding to a female shield ; 
punctuations very rare, small, unequal ; cervical grooves superficial, 
reaching almost to the anterior third , of the length of the shield no 
marginal groove and no posterior festoons ; three posterior longitudinal 
grooves, the median one a little shorter than the other two, which 
extend almost half the length of the shield ; eyes very small, depressed, 
scarcely visible, marginal, behind the emergence of legs I * marginal 
border clothed, especially in the posterior half, with long hairs joined by 
six to ten into transverse bands ; caudal appendage bearing on each side, 
at its base, a hemispherical projection, and clothed with a bunch of long 
hairs, behind and on each side a loose dorsal bunch of hairs, 
which join a ventral and longitudinal band of hairs, the two ventral 
bands unite in front of another sub-caudal appendage, which is chitinous, 
blackish, blunt and twice as long as wide. Ventral surface (VII, a) 
reddish brown, almost flat, with punctuations shallow, scattered, clothed 
with short hairs. Genital pore covered with a retrograde valve, situated 
•opposite the first inter-coxal space ; anus at the anterior summit of a 
•deep, median fossa, limited on each side, by an adanal shield, in the form 
of a sharp spine, long, chitinous, free in its whole extent ; the two spines 
unite on the median line at the . anterior edge of the anus, forming thus 
a fork with two teeth, which is prolonged in front by an irregular, 
smooth plate to the level of the last inter-coxal space ; stigmatic plates 
short, oval, edges brownish, stigmatic orifice nearly central, the whitish 
background is formed of numerous granulations hemispherical and shining. 
Rostrum (VII, c ), with dorsal base, wider than long, without lateral projec- 
tions, wider in front than behind, the posterior angles indicated by two 
small conical projections ; mandibles (VII, d) with inner apophysis conical, 
sub-terminal, transverse, with base large, tip bifid ; outer apophysis with 
two teeth, the terminal one small ; hypostome wide, a little longer than 
the palpi with eight rows of six to seven teeth, preceded by a surface 
covered with very numerous and very small denticles ; palpi very short, 
thick, the first article only visible on the ventral surface, in the form of 
a transverse band, the second at least as wide as long, rounded on the 
exterior, wider on the dorsal - face, narrower at its base, provided with 
hairs on its external dorsal edge ; the third almost twice as wide as long, 
forming exteriorly toward the middle of its exterior border a short point ; 
the fourth small, short, cylindro-conical, sub-terminal. Legs strong, 
thick, increasing from the first to the fourth, coxae contiguous, sub- 
triangular ; coxae I, II, and III provided with a very small spine near 
the internal angle of coxae I ; tarsi sub-conical, similar, increasing a little 
from I to IY, a false articulation, distal in I, proximal in II, III, and IY ; 
a strong terminal spur, long, preceded by a spine on the ventral side, and 
bearing at its base, on the dorsal border, an ambulacre with a disc as 
long a.s the spur, and terminated by two weak claws ; all the articles very 
chitinous, dark brown on their distal and ventral border ; with the 
fourth pair the second article is sub-cylindrical, the third strongly 
dilated exteriorly, is thus rendered rectangular, Avider than long, flattened
