Upper surface much covered with pearly scales. Rostrum short, with a well-marked 
punctiform fovea on the forehead, a channel along the middle reaching from the apex 
to near the fovea, but obsolete in its posterior part, and also with a rather small oblong 
depression on each side of the upper surface. ‘Thorax short, 24 millim. long, and 
about 32 millim. broad on the middle, with a broad depression along the centre, which 
sometimes has a few coarse punctures in it; the middle is dark in colour, except that 
there are usually some pearly scales along the depression ; on each side there is a rather 
vague vitta of similar scales; there are usually one or two vague depressions placed on 
each side at about half the length. Elytra short and broad, much covered with pearly 
scales, but with dark marks on the alternate interstices; these darker stripes have 
irregular edges—the inner stripe is elongate, extending beyond the middle, and the next 
one to it is still longer; on the outer interstices the dark marks are smaller; the 
punctures of the series are very definite, but not variolose; and the interstices are not 
at all convex. Under surface black, with some scanty pale scales. Legs short; 
anterior tibie not curvate externally. 
This species, on the upper surface, is entirely covered with scales: the dark marks 
that look like denuded spaces being actually covered with dark, very thin scales, that 
adhere very closely to the surface. It is possible, I think, that the pallid scales may 
change colour during the life of the insect, either by friction or staining or both; if 
this be the case, but little importance can be attached to the colour of this insect and 
its allies. 
Hoge has sent a series of nearly thirty specimens from Las Vigas; these appear to 
be in very fresh condition, and vary but little, even in colour. The examples from 
other localities are few, and none of them are so prettily and definitely coloured, the 
pale scales being deficient in quantity and irregularly distributed. This species may be 
known from its allies, however, independently of colour, by the short broad form, and 
the small size of the punctures on the elytra. JI can find no external sexual 
distinctions. 
I have examined an authentic example of the species from Schonherr’s collection.
