species is very characteristic. The basal striga is confined to an elongate point; the 
first fascia seldom unites with it (but does so in the specimen figured). ‘The elytra are 
smooth, without striee. | 
Only five specimens have been sent.

The basal striga is sometimes raised, as in C. bicarinatus ; in the Mexican examples 
it is nearly lost in the pale subscutellar line which unites with the first oblique fascia. 
16. Clerus tubercularis, (Tab. VIII. fig. 20.) 
Piceus, nitidus, elytrorum basi femoribusque rufis, illis tuberculo basali nigro bene elevato, apice pube grisea 
micante vestito. 
Var. elytris totis piceis, vel capite et prothorace toto rufis, vel pedibus piceis fere nigris. Long. 43-5 millim. 
Hab. Mexico, Cordova (Sal/é); Guatemata, Cerro Zunil, Capetillo, Aceituno 
(Champion). 
A Cerro-Zunil specimen is figured. 
This little species is very distinct, belonging to a section of the genus which have 
the elytra a little depressed behind the scutellar region ; in the present species the legs 
are very long, but the body rather short, very much more so than in the following 
species. The head and thorax are rather rough, and clothed with scanty pile of 
irregular length, the legs being also pilose. The basal tubercle is very conspicuous, 
the humerus being also a little raised. ‘The elytra are flattened below this part, yet 
the suture isa little elevated, and there is an obsolete costa running from the humerus, 
in a sinuate manner, along the side of each elytron, as far as the commencement of the 
grey apical pubescence. ‘he basal half of the elytra, with the exception of the 
tubercle, is usually rufous, and the apical half is always pitchy. Viewed from behind, 
the shining pubescence of the apex is only visible on each side; but this only depends 
on the way the light falls, for the whole apex is clothed with a similar hair. Several 
examples occurred at Cerro Zunil, a few only at Capetillo. There are three in Sallé’s 
collection of the variety with the head and thorax red, to which variety a single speci- 
men from Aceituno belongs.
