The intensity of colour, especially of the legs, varies, and 

 one specimen is almost entirely red. The mottling of the 

 scales consists of feeble dark spots on the elytra, and feeble, 

 short, lateral stripes on the prothorax, but in only two out of 

 five specimens are the markings at all distinct, whilst in one 

 they are entirely absent. The scape is remarkably stout, at 

 its widest being fully as wide as the space between the scrobes 

 at the apex of rostrum, and much wider than the club ; the 

 femora are also much stouter than usual. The sexual differ- 

 ences are but slight. 



Mandalotus Fergusoni, n. sp. 



Male. Black ; appendages somewhat paler, tarsi dis- 

 tinctly paler. Densely covered with muddy-brown scales, 

 variegated with small sooty spots. With short, stout, semi- 

 erect setae ; under-surface with fine setae in addition to scales. 

 Front and hind tibiae finely ciliated. 



Eostruni with carina quite concealed. Antennae mode- 

 rately stout. Prothorax moderately transverse, sides strongly 

 rounded : median line deeply impressed ; with minute scattered 

 granules entirely concealed by clothing. Elytra subtrisinuate 

 at base; with large round punctures, much wider than inter- 

 stices, but appearing much narrower through clothing ; alter- 

 nate interstices feebly raised. Basal segment of abdomen 

 feebly concave in middle. Legs, stout ; front coxae moderately 

 separated ; four front tibiae rather strongly bisinuate, the hind 

 pair strongly but obtusely bidentate internally. Length, 

 5 mm,.

The posterior tooth of the hind tibiae is just beyond the 

 middle, is more obtuse than the other, and has a peculiarly- 

 granulated appearance. Mr. Ferguson has sent three speci- 

 mens as belonging to this species, the male described above 

 and two females ; the male is perhaps partially abraded of 

 setae, as on the females they are much more numerous, and 

 being frequently white, both on the prothorax and elytra, 

 they give the upper surface a peculiarly-speckled appearance. 

 On the under surface of the females also the scales are denser 

 and paler, and the setae sparser and stouter, these, however, 

 being common sexual variations. The females (which measure 

 but 4 mm.) also have the basal segment of abdomen flat, the 

 hind tibiae edentate, and are more robust. 



Mandalotus seticollis, n. sp. 

 Male. Blackish : appendages dull-red. Upper surface 

 (except pronotum) densely covered with sooty-brown scales.
