DiCHELUS LATICOLLIS, BuriU., 



Plate XLII., fig. 32. 

 Handb. cl. Entomol., iv., 1, p. 111. 



Black, opaque, with the anterior tibiae and the antennae except the 

 club reddish, the propygidium and pygidium are nude, and the 

 abdominal segments have an upper patch of similar scales ; head 

 briefly bristly, the two median teeth of the clypeus are set close to 

 one another, the prothorax is almost glabrous on the upper side but 

 bristly laterally, hardly punctate in the posterior part, not densely so 

 in the anterior, and it is less narrowed laterally in the anterior part 

 than the other species of the genus ; scutellum not scaly ; elytra not 

 conspicuously narrowed laterally towards the apex owing to their not 

 being strongly sinuate below the humeral part, somewhat convex, and 

 callose at the apex, deeply but not closely seriate, punctate and 

 glabrous ; the three outer teeth of the anterior tibiae are less connate 

 at the base than in the other species of the genus, and the two upper 

 ones are a little more oblique ; the hind femora are very robust, 

 simple, with a distinct spine to the trochanters, the hind tibiae are 

 deeply emarginate at the base for one-third of the length and 

 developed from there into a broad lamina, dentate on each side 

 at the base and produced at apex into a very long, sub-transverse 

 inner mucro. 



Female : Like the male but still more glabrous on the prothorax ; 

 hind tibiae with a very distinct apical spur. 



Length 5^-7 mm. ; width 3^-4 mm. 



Hab. Cape Colony (Cape Town, Stellenbosch, Caledon, Heidel- 

 berg, Malmesbury, Clanwilliam).

Germ. Magaz., iv., 142. 



Black, with the elytra and legs brick-red, scaleless except on the 

 scutellum, and having a narrow band of yellowish scales on the edge 

 of the propygidium and on the sides of the abdomen ; head very 

 rugose and clothed with fulvous hairs somewhat bristly and not 

 dense, the two median teeth of the clypeus are nearly obliterated, 

 and the outer angles are proportionately sharper and more recurved ; 

 prothorax only slightly narrowed laterally towards the anterior part, 

 scabroso-punctate but not along the base, the punctures bear each a 

 flavescent, erect hair but are not very dense ; scutellum somewhat 

 ogival ; elytra a little convex, normally attenuate laterally below the
