DELIATHIS.—HAMMODERUS. . 99 
the eyes are straight instead of rounded and convex. From Teniotes they are further 
distinguished by the apical ventral segment being destitute of spiniform projection at 
the angles.

Lacordaire suggested that this might be a variety of D. buquett. It differs only in 
the grey and white vitte being absent, the glabrous black integument occupying their 
place. A Guatemala specimen in M. Sallé’s collection has traces of grey tomentum in 
the position of the vitte.

5. Deliathis pecilodryas. 
Tomento sordide albo passim vestita, tuberculis thoracis dorsalibus tribus spinaque laterali, elytrorum guttis 
numerosis discretis (juxta basin tubercula obtusa formantibus) nigris, nitidis; capite thoraceque quam in 
cateris speciebus latioribus, elytrisque versus apicem paullo minus attenuatis, apice ad suturam paullulum 
dehiscentibus et breviter acute spinosis ; mesosterno minus prominulo.

Hab. Mexico, Mirador, province Vera Cruz (Sa//é). 
One example of this distinct species is in M. Sallé’s collection. The spots on the 
elytra are innumerable and pretty equally sprinkled over the whole surface; they vary 
in size, but are never so large as the black spots of D. nivea.
