distinct and rounded, apical processes shortly acuminate in both 

 sexes ; just Avithin the apex of each elytron a very large pro- 

 minence formed by the agglomeration of about a dozen tubercles. 

 Upper surface convex, with rows of shallow and ill-defined 

 punctures separated by small granules ; interval 1 with a row of 

 granules disappearing behind middle ; intervals 2 and 3 with rows 

 of small closely-set subconical tubercles as far as the summit of 

 the declivity, beyond this with 3 or 4 much larger and sharper 

 tubercles, which are subcristate on interval 2 ; intervals 4 and 6 

 with only a very few small tubercles about middle ; 5 and 7 with 

 rows of small conical tubercles as far as declivity only ; tubercles 

 with depressed dark setfe ; colour black, bare, except for several 

 large irregular patches of round white scales. Abdomen with a 

 lateral row of rounded impressions on each segment ; $ with 

 two sharp processes on the posterior margin of the penultimate 

 segment — resembling those in ahruptecostatus Gyl. Legs with 

 dense white scaling and setse ; posterior tarsi Avith the three joints 

 subequal in leng-th and breadth.

Type in the Stockholm Museum. 



A very distinct species, and in spite of its wide range it appeara 

 to be very uncommon.

Long. 22, lat. 9 mm. 



Head convex, without any central fovea or carina, the punctua- 

 tion hidden by very dense brown scaling ; anteocular furrows 

 distinct. Bostrimi not incised at base, as long as head and 

 prothoi-ax, strongly curved and dilated apically ; at base a 

 large stout double horn the apices of which are obtuse and 

 divergent. Upper surface with a broad central furrow throughout 

 and thickly covered with large greyish scales ; lateral sulci not 

 uniting at base, of about equal length, bx'oad and distinct, coarsely 

 punctured and filled with scales, the interval between them 

 narrowly carinate ; scrobes directed beneath base of rostrum ; 

 inferior basal furrow very deep. Antennce with scape not reaching 

 eye ; first and second joints of funicle subequal. Prothorax as 

 long as broad, apex narrower than base, sides very little rounded, 

 broadest about middle, dorsal anterior margin convex, ocular 

 lobes very strongly developed. Upper surface convex, irregularly 

 set with conical tubercles, leaving a broad central furrow con- 

 taining a short but strong carina ; apices of tubercles bare and 

 with depressed dark setae, the interstices with dense variegated 

 scaling. Elytra oblongo- ovate, shoulders prominent, sides sub- 

 parallel for three- fourths of the length, apical processes very short 

 and obtuse in both sexes. Upper surface convex, with regular 

 rows of shallow foveolse ; interval 1 entirely devoid of granules 

 or tubercles ; interval 6 Avith a more or less abbreviated roAv of
