Adult. — Body elongate and narrow witli lateral borders, straight 
or almost straight, parallel, contracted at the anterior extremity into- 
a rounded point, almost straight or slightly convex on the posterior 
border and joined to the lateral borders by rounded angles; dirty 
yellow when young, brownish to bluish black when replete. Dorsal 
surface (111 , a) margined by a wide raised border (not so prominent 
when fully engorged), similar to the rest of the integument, and 
forming on the anterior end a deep median Y-shaped fold; the 
remainder of the dorsal surface excavated or undulating, with usually 
an anterior elevation, corresponding to the rostrum ; on this elevation, 
four smooth symmetrical depressions, numerous depressions within 
the marginal border, surrounding this elevation in a circle. In the- 
posterior half a median line of smooth depressions extending from 
posterior border anteriorly about one-quarter of the length of the 
body. A short distance from the anterior end of this median line is a 
single large depression, with two large depressions on each side of it, 
near the lateral margins; extending posteriorly from the two posterior 
of these depressions is a line of nits, similar to the median, but curved 
inward, and clo > to and following the lateral margin. On the ventral 
surface (111, b) a pre-anal groove not very deep, almost straight, 
ceasing at the coxal folds ; a post-anal groove composed of a transverse 
fold, straight, or a little curved anteriorly or posteriorly, very near 
the posterior border, a large circular depression at each extremity; an 
anal groove, ceasing at the post-anal groove, its depth occupied by 
smooth depressions resembling those on the dorsal surface ; sub-coxal 
and coxal folds well marked, the sub-coxal ceasing at the coxal 
grooves which pass anteriorly between the coxae of the first and the 
second pair of legs, which they separate; posteriorly they extend 
behind coxae IY toward the lateral margin. Stigmata on the dorsal 
surface of the sub-coxal folds, the stigmal opening almost longi- 
tudinal, semi-lunate. Anal ring almost as wide as long, anal opening* 
provided with two or four spines on each valve. Genital pore opposite 
posterior margin of coxae I ; female pore long and narrow, that of 
male short and wide. No eyes, but two swellings on margin above 
legs I and II without any eye-like spots. Integument thin, with 
hemispherical granulations, shining, contiguous, almost equal in size, 
forming by their uniformity a network of meshes limited by folds, 
the centres of which bear one to four very short claviform hairs, with 
wide bases. Rostrum elongate lodged in a deep cavity, with lateral 
borders very well developed in the form of cheeks like an inverted 
Y-shaped hood, which can fall down and protect it ; base of rostrum 
wider than long, with sides convex, and several long hairs near “lateral 
margins ; set on a narrow base, the integument of which is finely 
honeycombed and wrinkled crosswise, this base allows the rostrum 
to be inclined forward and to be retracted ; mandibles (111 , e ) with 
digit large and thick, inner apophysis close to the base, as wide as 
long, provided with three equal teeth pointing backward, outer 
apophysis tridentate, with posterior tooth stronger, provided at its 
base with an additional denticle, anterior tooth very small;
