Mandalotus mirabilis, n. sp. 



Male. Black ; antennae and tarsi reddish. Densely cloth- 

 ed with muddy-brown scales. With moderately dense but 

 rather short setae, which on the elytra are irregularly distri- 

 buted. Under surface, except on sides, with long, thin straw- 

 coloured hair. Front tibiae with dense and long cilia. 



Rostrum stout, carina distinct throughout. Antennae 

 rather thin. Prothorac decidedly transverse, sides very 

 strongly rounded, apex subtubular ; with numerous oblong or 

 elliptic granules, more or less transversely or obliquely ar- 

 ranged. Elytra somewhat sinuous at base, with a rather 

 large tubercular swelling just behind each shoulder on the 

 side, elsewhere (especially about and on posterior declivity) 

 with subtubercular elevations. Ahdome.n concave along mid- 

 dle. Legs strong; front coxae widely separated; tibiae wider 

 than usual, all more or less strongly curved, the hind pair 

 distorted at apex. Length, 9^ mm.

 leay Museum). 



Larger and probably more distinct than any other known 

 species. From the description of valgus, and all other spe- 

 cies, the long clothing of the under surface will readily dis- 

 tinguish it ; this clothing appears to be of three kinds — long 

 thin hair clothing most of the under surface, towards the 

 sides interspersed with stout setae, and at the sides scales. 

 The front tibiae have denser and perhaps longer ciliae than 

 any other species here noted ; the hind tibiae are rather sparse- 

 ly and the middle tibiae scarcely ciliated. The clothing is 

 so dense as almost to prevent the sculpture being traced 

 through it : on abrasion the prothorax is seen to have a dis- 

 tinct median line, and to be covered with numerous granules 

 appearing like interrupted carinae. The scutellum appears 

 to be of comparatively large size, although normally quite 

 concealed. The elytral punctures are often quite hidden, but 

 are large, round, and wider (except at the thickened parts) 

 than the interstices. Each of the middle coxae appears to 

 be concave internally, or to be supplied with an arcuate 

 carina, the convex side of which is towards the side. The 

 hind tibiae are very strongly and suddenly inflated and curved 

 at the apex (in addition to the ordinary curvature), this 

 portion being hisfhly polished internally : at its inner apex 

 it is terminated by three small spines or teeth ; the tarsi are 

 set on the inflated portion. The front tibiae appear to be 

 slightly twisted, with a carina or ridge marking the upper 

 side of each.
