The white scales in places (but especially on the under 
surface) are slightly tinged with green, but they are nowhere 
shining ; they clothe the head (on one specimen there is a 
broad median patch of brown scales extending from the base 
to between the antennae), rostrum, scutellum, under surface, 
and legs ; form four lines on the prothorax (two median and 
two lateral), and are distributed in irregular patches on the 
elytra ; on the latter they cover from one-fourth to one-half 
of the surface, on the prothorax they cover less than half. Tbp 
setse are rather numerous on the legs and antennae, rather 
sparse on the prothorax, and very sparse on the elytra : they 
are nowhere dark in colour. The elytra to the eve appear 
almost seriate-punctate, the punctures being partially visible,"^ 
but the striae verv indistinct. 
SyNOMUS -^RUGINOSUS, n. sp. 
Black, appendages reaaish. Densely clothed with golden- 
green scaies : abdomen and appendages with white scales (with 
an occasioiial golden gleam) and with white setae. Elytra with 
long, stiff, upright, whitish bristles, prothorax with similar 
but shorter bristles, and still shorter ones on head- 
Utad large and very feebly convex. Eyes almost round. 
Rostrum slightly diminishing in width from base to apex, 
with a narrow, impressed line, which terminates posteriorly 
in a narrow, ocular fovea. First joint of funicle distinctly 
longer than second. Protli<jr(ir strongly transverse, base 
strongly bisinuate, sides lightly rounded. ScuttLiu7n minute. 
Wyfra ovate, widest at about the middle, at base closely ap- 
plied to and no wider than prothorax : striate punctate- Ft- 
innra minutely dentate. Length, 4| mm.

On both specimens before me several obscure patches of 
greyish scales are to be seen on the prothorax and elytra, but 
these may be due to an oily exudation. The elytra appear to 
be rather finely striate only, but on abrasion fairly large 
punctures are exposed. The green scales will readily dis- 
tinguish it from rephaloffs. 
The elytra at the base no wider than the prothorax f is 
practically the only character Pascoe gave as distinguishing 
Sijiiowii--< from Mi/llort^riix, but it appears to be a very good 
* Thaso are the only ones that are even partially vi.sible, all 
the punctures on the prothorax and els;ewhere being quite con- 
cealed. 
+ This i.s due to the naTi'owiug of the elytra to the base, the 
prothorax being normal : in several species of .l/»/?/or^ru.s the 
elytra at the ba.se are no wider (in one .species they are narrower) 
ttinn tlip prothorax. but this i.s due tf> the hind margins of the 
prothorax being widened out to the base.
