the apex. Ante-apical striga semicircular, subinterrupted in the middle; 
the two dorsal impressions very shallow or rather null; ante-basal striga 
irregular, partly interrupted. Scutellum smooth. Elytra short, convex, 
subquadrate, subsemicircularly descending from above the middle; 
striate-punctate : strias sharp at the base, successively shallower towards 
the posterior part, especially the median oues ; interstices broad, flat, 
very slightly and finely transversely rugulose.

Almost the form of Attel. nitidus , F. Sch., though much smaller. 
Rostrum proportionally thin, at least as long as the head, moderately 
ampliate towards the apex, very slightly punctulate ; its base, the fore¬ 
head and head constructed as in the preceding species. Thorax shorter 
than broad ; sides obliquely roundly ampliate towards the base ; convex; 
punctures strong at the sides underneath, smaller and shallower—but 
evident—each side of the disk, more or less strigose at the base, almost 
null at the centre and anteriorly. Scutellum subquadrate, transverse; 
posterior angles rather acute; apex truncate, with the middle at the 
suture somewhat angulate. Elytra subparallel, convex, as in Attel. 
violaceus and Attel. nitidus.
