1904.] OP THE GEXUS HIPPORRHINUS. 93 



intei'vals 3, 5, and 7 with complete rows of small, closely-set, 

 conical tubei'cles, which become lai'ger and sharper behind ; apices 

 of tubercles not bare, each with a depressed pale seta, the whole 

 surface fairly densely covered with brown or grey scaling. Legs 

 coarsely punctured and with sparse pale scaling ; posterior tai'si 

 broad, setose, the joints of the same width, 2nd and 3rd subequal 

 in length, 1st longer. 



Cape Colony. 



Type in the British Museum (coll. Banks). 



Fabricius' type is lai-ger than any other specimen which I have 

 seen and has the I'ows of, tubercles on the intervals 2, 4, and 6 

 unusually well developed. Schonherr was vmable to recognise 

 this species, but I found three examples of it in the Stockholm 

 Museu.m. It appears, however, to be a rare insect.

Long. 12-20, lat. 6-9 mm. 



Head convex, with scattered coarse punctures and pale scales 

 forehead with a broad and deep centi^al furrow ; anteocular 

 furrows shallow. Rostrum not incised at base, scarcely as long- 

 as prothorax, distinctly angulated beyond middle. Upper surface 

 plane near apex, but with a broad shallow central furrow in the 

 basal half, sometimes containing a faint cai-ina, with shallow 

 punctuation and sparse pale scaling ; upper lateral sulci very deep 

 and meeting at base, thus throwing into prominence the edges of 

 the central furrow, lower sulci curved and longer but veiy 

 shallow ; scrobes lateral but oblique ; inferior basal furrow absent. 

 Antennce with scape scarcely reaching eye ; the two basal joints 

 of funicle subequal. Prothorax longer than broad, apex narrower 

 than base, sides not much rounded, broadest about middle, 

 antei'ior margin convex, ocular lobes well developed. Upper 

 surface with a strong but abbi-eviated central carina contained in 

 a broad and deep furrow, the sides of which are formed by a row 

 of more or less agglomerated tubercles ; the lateral poitions set 

 with low rounded tubercles arranged in three irregular rows 

 leaving smooth narrow interspaces ; tubercles bare and with 

 short depressed dark setse, the interstices with dense brown 

 scaling. Elytra broadly ovate, shoulders sloping, sides not much 

 rounded, broadest about middle, apical processes very short and 

 •obtuse in both sexes, basal margin deeply sinuate, scutellum very 

 distinct and covered with pale scaling. Upper surface convex, 

 with regular rows of shallow punctures separated by large 

 granules ; interval 1 costate and with a row of small very de- 

 pressed and elongate tubercles ceasing behind middle ; intervals 

 2, 4, and 6 plane and without tubercles ; 3, 5, and 7 costate and 

 with complete rows of tubercles, those in the basal part of 3 and 

 5 more or less strongly depressed and elongate, the rest conical; 

 tubercles bare and usually with very short depressed dark seta?
