Nephelotus Aurivillii, n. sp. Q. 
Agreeing in general appearance with the type of the 
genus, N. licheneus Pasc. (? = Anhammus conspersus Thoms.), 
but easily distinguished by the different sculpture of the 
elytra. 
Length from the top of the antennary tubers to the 
end of the elytra 24 mm., breadth at the shoulders 8,5 
mm. — Derm black, apical half of elytra indistinctly 
variegated with pitchy red, epipleurae entirely of this 
colour, the 34 and following joints of the antennae, as far 
as they are present (5), and the legs reddish testaceous, 
the latter with the exception of the black apical half of 
the femora, the base of the tibiae and the apex of the 
3rd and 4th tarsal joints. The whole insect is covered with 
a dense pale ochreous pubescence, less dense however on 
the testaceous parts of the antennae and legs, and absent 
on the granules and punctures which cover the elytra in 
regular longitudinal oblique lines; at two thirds of the 
length of the elytra a curved irregular black band is present, 
formed by naked spots which are confluent towards the 
suture and transverse towards the sides. The scutellum has 
a glossy line along the middle. 
The antennary tubers are closer together and less di- 
vergent than in licheneus and have on the middle of the 
frontside a distinct keel, which reaches not quite to the
