MADARUWUS. 379 
) 
Very like WM. vorticosus, but less elongate and almost glabrous above (the oblong 
ochreous patch at the base of the third elytral interstice and a few scattered sete 
excepted) ; the prosternum tumid between the cox anteriorly in the male, deeply 
bifoveate at the apex; the rostrum very similarly formed, and the antenn inserted 
at about the middle, in the two sexes, the anterior femora obsoletely dentate. Varies 
from 4—64 millim. in length.

¢. Anterior tarsi hairy, the anterior tibie also with a few hairs along their inner edge at the apex; rostrum 
with the narrower apical portion about as long as the basal portion ; first ventral segment flattened down 
the middle. 
@. Rostrum with the apical portion a little smoother, otherwise as in the 3.

Smaller than MW. distigma ; the prothorax shorter, more rounded at the sides, abruptly 
constricted in front, and much smoother; the elytral interstices very finely uniseriate- 
punctate, the oblong, ochreous or white patch at the base of the third sometimes 
reduced to a narrow streak; the prosternum not tumid in the male, deeply foveate 
as in M. distigma; the anterior femora distinctly dentate. The length varies from 
4-5 millim. Dr, Sjostedt informs me that this species is not represented in the 
Stockholm Museum. 
18. Madarus bisignatus, sp. n. (Tab. XIX. figg. 4, 4a, 3.) 
Elliptic, shining, black, with a slight brassy lustre; the elytra each with a dense oval patch of yellowish- 
white scales at the base of the third interstice and often a small spot at the base of the second also; the 
punctures of the under surface and legs each bearing a minute whitish scale. Head closely, minutely 
punctate, transversely depressed between the eyes; rostrum arcuate, moderately stout, longer than 
the head and prothorax, finely punctate, the antenne inserted behind the middle, the antennal club 
ovate. Prothorax transverse, rounded at the sides (conspicuously so in the ¢), constricted and much 
narrowed in front; closely, rather coarsely punctate, rugose on the flanks. Scutellum small. Elytra 
rounded-triangular, comparatively short, sharply striate, the strie feebly punctate, the interstices faintly, 
asperately, uniseriate-punctate. Pygidium transverse, densely punctate. Beneath closely and very 
coarsely, a broad space down the middle of the metasternum and abdomen finely and sparsely, punctate, 
the anterior half of the prosternum rugose. Prosternum bifoveate or finely sulcate in front, in the ¢ 
transversely tumid or sublamellate between the widely-separated coxe anteriorly, the basal process 
broadly truncate behind. Femora shallowly sulcate, the anterior and intermediate pairs feebly dentate, 
Anterior tibiee with a few hairs at the apex within, and the anterior tarsi slightly dilated and hairy, 
in the 3. 
Length 2-31, breadth 15-14 millim. (¢ 2.)
