each three hands of elongate, somewhat hair-Uke, greyish-white or 

 sHghtly flavescent scales, often partly obliterated, hut with the 

 hroader juxta-sutural band always more distinct ; hind femora 

 simple but with the spine of the trochanters greatly developed ; 

 hind tibiae also as in D. clcntipes, but not at all grooved or concave 

 underneath, and therefore not carinate inwardly. The shape of the 

 tibia3 is nearly the same as that of D. acanthopus, from which 

 species it is at once distinguished by the more elongate facies ; the 

 female is like that of D. dentipes, and the pygidium has no denuded 

 patches.

DiCHELUS LUCTUosus, n. spec. 



Male : Black, shining, head and prothorax clothed with black 

 villose hairs, prothorax with an interrupted narrow band of white 

 scales ; scutellum scaly, elytra with a post-median juxta-sutural 

 narrow band of white scales, pygidium not scaly ; the two median 

 teeth of the clypeus are very small, yet distinct ; the elytra are a 

 little convex, not costulate, and are strongly callose at the apex, they 

 are sparsely punctate, the punctures of the sides and in the pos- 

 terior part bearing a somewhat thick short decumbent hair; hind 

 femora simple, but with the trochanters produced into a long, sub- 

 horizontal spine ; hind tibiae compressed, grooved underneath, but 

 with the edges of the groove simple and the inner apical parts 

 strongly mucronate ; under side briefly villose, the hairs black, 

 upper side of abdominal segments with a small patch of white 

 elongate scales. 



Female unknown.

This species seems to be very rare. It very much resembles 

 D. dcnticeps in general form, but is at once distinguished from it by 

 the long spine of the trochanters, which is absent in the latter, 

 and also by the colour of the elytra and the shape of the hind 

 tibitC.

Black, with the elytra chestnut-brown, and the legs chestnut-brown 



or chestnut-red ; head and prothorax sub-villose, but clothed also 



under the hairs with greyish or slightly flavescent scales which 



become much denser in the posterior part ; scutellum densely scaly ;
