222 Mr. G. R. Waterhouse's Monograph on 



Long. Corp. 34- lin. 



Obs. The character from which I have named this species (viz, 

 the elytra being furnished with pubescence arranged in longitudinal 

 striae), and the red colour of the legs, at once distinguish it from 

 either of the others. The clypeus of the male is not very deeply 

 emarginate; the lateral processes are wide apart and diverging ; the 

 head is thickly punctured and transversly indented posteriorly. The 

 thorax is coarsely punctured, but the punctures are not thickly dis- 

 posed ; the dorsal channel is broad and shallow ; the two foveae, 

 which in most of the foregoing species is confined to the lateral mar- 

 gins of the thorax, are in this extended from thence to the dorsal 

 channel, and form a transverse indentation, which becomes deeper 

 and broader as it approaches the margins, which are toothed. Scu- 

 tellum short; anterior tibiae distinctly bidentate externally; the inner 

 tooth acute ; the outer one (which forms the apex of the tibia) is 

 recurved. 



I have examined four specimens of this species; they are in the 

 collections of the Rev. F. W. Hope, Mr. Spence, and the Entomo- 

 logical Society. I have also one in my own cabinet, which was 

 o-iven me by Sir Patrick Walker, who informs me there are speci- 

 mens in some of the collections in Edinburgh.

Obs. In this species the clypeus of the male is not deeply emar- 

 ginate ; the head is rugosely punctured anteriorly, less so posteriorly; 

 thorax distinctly punctured, the punctures confluent in the dorsal 

 channel, which is shallow and very broad ; the lateral fovese are very 

 large and shallow, and occupy nearly the whole portion of the thorax 

 from the dorsal channel to the lateral margins, which are distinctly 

 toothed ; anterior tibiae bidentate externally : these processes are 

 very distinct, and in their form and position nearly resemble D.^^zYz- 

 striata.
