extreme base; metasternum shorter than the mid-soxe, 
with a distinct antecoxal fold, the episternnm produced 
inwards at the base, the episternal suture visible only in the 
basal half, the hind cox meeting the elytra. Venter with 
the intercoxal process angulated and narrower than the hind 
coxe, the hind margin of segment 1 sinuate, and segment 2 
longer than 3 and 4 together. Legs with the femora mode- 
rately clavate; tibiz straight and cylindrical, not mucronate 
at the apex, the hind corbels open and bare ; ; tarsi broad, 
the claws connate. 
3d unknown. 
Genotype, Synechops irregularis, sp. n. 
A rather isolated genus, readily distinguished by the 
following combination “of characters : the complete absence 
of any dividing-line between the rostrum and forehead, the 
open corbels of the hind tibiz, and the simple mandi ibles. 
Synechops irregularis, sp.n. (PI. I. fig. 8.) 
@. Black, with uniform, dense, sand-coloured scaling. 
Head yather strongly convex transversely, shallowly im- 
pressed on each side behind the eyes, the long scale-like 
sete quite recumbent; eyes nearly ‘circular and hemi- 
spherical. Rostrum stout, parallel-sided, almost flat above, 
but with the dorsal edges eae rounded away, with 
coarse confluent punctation (mostly hidden by scaling) and 
with a central furrow (continuous with that on the head) 
from the base to the middle. Antenne with joints 3-7 of 
almost equal length, but 7 distinctly broader “ the 
others, trapezoidal. Prothorax broader than long (23 x 2), 
the sides moderately rounded, broadest a little before the 
middle, with a very shallow transverse impression at about 
one-fourth from the apex, the basal margin very gently 
arcuate and not raised, the apex truncate ; the upper surface 
with coarse confluent punctation (mostly hidden by the 
scaling and stout recumbent sete) and no central furrow or 
carina, but with some irregular impressions on each side 
behind the middie ; the dorsal outline almost level, forming 
a continuous curve with that of the rostrum and head. 
Elytra oblong-ovate, rather broadly rounded behind (as seen 
directly from. above), the basal margin gently sinuite ; the 
dorsal outline rising from the scutellum, then almost. flat, 
and sloping steeply behind, the apical part quite vertical ; 
the punctation coarse and quite irregular, except for a row
