have on each side two faintly raised costae covered by a series of 

 sHghtly Hghter yehow scales ; liind femora very robust and having a 

 very small tooth at the apex, underneath close to the knee the 

 trochanters are produced into a sharp spine ; the hind tibiae are 

 broadly but not very deeply scooped inwardly, and the edges are 

 sharply carinate, the outer one is very shai'ply angular near the knee 

 and the inner is produced at a short distance from the apex into a 

 conspicuous mucro-like tooth, there is a small apical spur, and the 

 angles of the tibia are not mucronate on either side ; basal tooth of 

 the anterior tibiaa obliterated in both sexes ; hind claws single, 

 simple. 



Female : Like the male, but the prothorax is covered with appressed 

 squamose hairs instead of scales, and the apical spur is more 

 developed. 



Length 7-S mm. ; width 3^-4 nun.

 more or less regular marginal one ; elytra irregularly bespi-inkled 

 with ovate white scales ; scutellum, propygidium, pygidium, and

 little more obliquely attenuate latei^ally towards the apex than the 

 other species of MonocJtclns, and sub-incised at the tip ; prothorax 

 rugose, very briefly setulose, with an apical and lateral series 

 of stiff, long, black bristles, and in the median part a narrow, 

 median furrow ; elytra with a faint, discoidal costule, very closely 

 punctate, each puncture bearing a very short, fuscous seta ; pygi- 

 dium with a narrow denuded median longitudinal line reaching from 

 the base to two-thirds of the length ; anterior tibiae tri-dentate 

 outwardly, but with the basal tooth very small and inconspicuous ; 

 hind femora robust, moderately thickened, simple, trochanters non-

 and very angular there, lower apical angle sharp and slightly pro- 

 duced, but not mucronate ; claw of the intermediate legs with a

Female : Like the male, but the scales are a little wider on the 

 upper side and golden-yellow ; the denuded band on the pygidium 

 is very well defined, and the hind tiliiie have a distinct apical spur.
