MONOCHELUS CALCARATUS, Burm., 



Handb. d. Entomol., iv., 1, p. 160. 



Male : Black, with the elytra red and the legs piceous red ; pro- 

 thorax with five bands of flavescent scales, scutellum scaly, elytra 

 with rows of scale ; apical part of the propygidium, the whole 

 of the pygidium and the sides of abdomen and of pectus scaly ; 

 head scaly; clypeus sub-obliquely attenuate, distinctly emarginate at 

 tip and with the outer angles moderately rounded, margins slightly 

 reflexed ; prothorax ampliate laterally in the median part, punctulate 

 laterally, but less so in the discoidal part, the median part of which 

 is grooved longitudinally, the scales of the marginal and sub-lateral 

 bands are set in the punctures, between the scaly groove and the 

 sub-lateral band there are also a few scales, and the anterior and 

 lateral margins are fringed with long yellow bristles ; elytra elongate, 

 distinctly attenuate laterally towards the apex, although not so much 

 ampliated at the base as in M. natalensis, and having equi-distant 

 elongate whitish scales disposed in one scale rows, and set in dis- 

 tinct seriate punctures ; the scales on the pygidium are not closely 

 set, and the hind legs are also scaly ; the hind femora are much 

 thickened, and the trochanters are produced into a long slightly 

 curved spine which is detached from the thigh at a short distance 

 from the apex, and projects much beyond the knee, the tibiae are 

 somewhat impressed inwardly but not grooved, the two edges are 

 very sharp, and the inner one is produced into a very long, curved 

 apical mucro with two short bristles at the tip ; claws of hind legs 

 single, not cleft, and having underneath a very distinct sub-horizontal 

 tooth. 



Female : The female is similar to the male in colour, sculpture, 

 and vestiture, but the punctures on the elytra are seldom filled with 

 scales ; the hind claws are a little ampliate underneath but not 

 dentate, and the hind tibiae have an apical spur. 



Length 7-8 mm. ; width 3|— 4-| mm.

MONOCHELUS PRINCEPS, U. SpeC. 



Male : Similar in general appearance to M. Icetus ; the shape and 

 vestiture of the head are similar ; the prothorax has the median 

 groove filled with flavescent scales, the outer margins, including the 

 basal one, have a broad band of similar scales, and on each side of 

 the groove there is a short band reaching from the apex to about the 

 median discoidal part ; the scutellum is scaly and on each elytron
