MONOCHELUS SIMPLICIPES, n. sp. 



Male : Black, with the elytra testaceous red, antennge rufescent 

 with the clul) black ; head very rugose, clypeus slightly attenuatea 

 laterally with the outer angles moderately rounded, and the margins 

 somewhat reflexed ; prothorax having instead of a median groove a 

 longitudinal, not much raised and rounded costate carina and a 

 shallow, l)ut somewhat broad furrow on each side, which, like the 

 two median furrows are iilled with yellow scales, the median carina is 

 impunctate ; and there is also an impunctate longitudinal space 

 on each side of the disk ; scutellum rugulose ; elytra deeply and 

 irregularly punctate and rugose laterally, and having a distinct costa 

 in the discoidal part, the intervals on each side of the costa are 

 somewhat deep and broad, humei-al callus well developed, the juxta- 

 humeral interval is partially filled at the base with greyish-white 

 scales, a few of which are very sparsely sprinkled here and there ; 

 pygidium l^lack, glabrous ; abdominal segments also glabrous ; pectus 

 scaly ; anterior tibias bi-dentate outwardly but incised above the 

 second tooth, the incision sharply angular; anterior and interme- 

 diate claws somewhat thick, posterior ones with a short, lamellate 

 inner one reaching only to one-fourth of the length of the outer one, 

 both claws are simple ; hind femora robust, simple, trochanters not 

 spinose ; hind tibitfi elongated and moderately dilated at the apex, 

 somewhat compressed outwardly, slightly concave inwardly but 

 more deeply scooped at the tip, the apices of the groove are very 

 sharply angular, the inner one being sub-mucronate, and there is 

 a small apical spur. 



I have seen one male example only, and it is quite possible that 

 this specimen had partly lost his scaly covering. 



This is the only Monochelus in which the median part of the pro- 

 thorax is bluntly carinate. 



Length 7^ mm. ; width 4 mm. 



Hah. Natal (Karkloof). 



Monochelus jucundus, n, spec. 



Male : This species is very closely allied to M. iMrtitus, the facies 

 and sculpture are identical, but the elytra are piceous red, and more 

 distinctly costate, the scales are whiter and similarly arranged, but 

 the hind legs are differently shaped ; the trochanters of the hind 

 femora are not produced into a spine, and the hind tibiae are gradually
