Communicated by Herr von Winthem. This species resembles 

 closely D. holosericetis, but it is a little larger, everywhere punctate, 

 and more densely hairy ; the distinctive character is the much more 

 depressed elytra, in every other respect it is similar, but the hairs 

 and the scales are yellow instead of white, and the whole pygidium 

 is covered with scales ; the anterior legs are light red ; in the male 

 the hind thighs have the trochanter spinose, but are otherwise simple, 

 but the articulation of the knee is aculeate on each side, the hind 

 tibiae are curved and have a basal tooth underneath near the knee,, 

 there is no apical spur. "

This species is closely allied to the preceding one {D. dcnticcps), 

 but the extremely conspicuous sheen makes it resemble more closely 

 still D. hivittatus. Head, anterior part of the prothorax, and 

 body black, the apical margin of the clypeus is quadi'i-dentate, but 

 the two median teeth are very feeble and set close to each other ; 

 the anterior part of the prothorax is shining, somewhat thickly 

 punctulate as on the vertex of the head, and each puncture bears 

 a hair, all of them being somewhat scattered ; there is in the 

 posterior part a furrow set with yellow scales which are also 

 spread on the posterior part. Similar scales are to be seen on the 

 scutellum, the scapula?, the sides of the pectus, the propygidium and 

 pygidium, the latter having two black patches ; the elytra are very 

 shiny and have some short, bristly hairs only on the sides and at the 

 apex, they are entirely red, as are also the legs, the antenna?, and the 

 palpi ; in the male the long hind legs have the trochanters strongly 

 spinose, and the thighs wnth a spine in the inner part of the 

 articulation of the knee ; the hind tibiiB are curved and simple but 

 mucronate at the apex, and without apical spur ; the hind tarsi are 

 setose with the setae long, and have two unequal claws, one of which 

 is simple, long and thick, and a shorter cleft one ; the claws of the
