towards the median part than the anterior, which is nearly straight, the 
supra- marginal patch is, however, broader than the uninterrupted part of 
the band ; the posterior band which does not begin at the very suture is 
still narrower than the anterior, and more broadly interrupted past the 
centre.

Black, covered with a dense sub-flavescent pubescence ; the five basal 
antennal joints are black, the others yellow ; on the elytra the lunules and 
bands are yellow; head and prothorax closely, and only moderately, 
unevenly punctured ; frontal part without any distinct longitudinal smooth 
line ; elytra very closely punctate, sub-shagreened ; they have on each 
side an elongated arcuate lunule beginning in the basal dorsal part, but 
with the curved part not quite connected with the suture, an elongated 
lateral patch, a very narrow sub-median transverse band deeply and 
broadly bi-sinuated on either border, and occasionally slightly interrupted 
in the centre, and a somewhat broader post-median band also broadly 
sinuated on either border, but with the part extending from the suture to 
the median dorsal part broader than in the anterior ; the flavescent 
pubescent patch on the hind part of the elytra is also fairly distinct. 
Length 9 mm. ; width 3|- mm.

Black, with the head, prothorax, scutellum, abdomen, pectus, and legs 
clothed with a very dense, silky, yellowish pubescence ; antennae black 
with the exception of the 3-5 joints which are red or reddish flavescent ; 
head somewhat broadly and deeply punctate, and with a faint, short, 
smooth line abutting on the transverse impression of the epistome ; pro- 
thorax of the normal shape, covered with contiguous, deep, not broad, but 
slightly scrobiculate punctures, and having a very slight median impres- 
sion ; scutellum closely punctate ; elytra sub-cylindrical, hardly wider 
across the posterior part than at the base, finely shagreened, bi-costulate 
on each side in the dorsal part, clothed with an appressed, brief, slightly 
flavescent pubescence, pale yellow, somewhat straw-colour with a narrow 
basal and lateral fulvous margin which disappears, however, when the 
colour turns to reddish fulvous, which is occasionally the case, and having
