98 MR. G. A. K. MAKSnALL OX COLEOPTERA [Jan. 1 9, 



Cape Coloxy : Craliamstown (coll. Pascoe). 



Type in the British MTiseum. 



Closely allied to the aberrant thoracicus Fahr., from which it 

 may be distinguished, among other points, by the dorsal angula- 

 tion of the rostrum, the inferior direction of the scrobe, the more 

 deeply excavate head, the more declivous and less strongly costate 

 elytra, and the shorter tarsi.

Long. 13, lat. 6 mm. 



Head very sti'ongly flattened, or even shallowly excavate, in 

 front, with a short but deep central stria neai- base of rostrum ; 

 punctuation close bvit faint, usually hidden by dense brown 

 scaling ; anteocular furrows distinct. Rostrum comparatively 

 slender, rather longer than head and prothorax, not incised trans- 

 versely at base, distinctly curved. Upper surface with a con- 

 tinuous central furrow containing a fine smooth carina, which, 

 however, is variable, being sometimes almost obsolete, the edges 

 of the furrow ai-e obtusely costate and set with distant granules ; 

 lateral sulci deep, the upper pair rather longer and uniting at 

 base, which is slightly raised, the lower pair cui"ved strongly 

 upwards at base ; scrobes directed beneath base of rostrum ; in- 

 ferior basal furrow distinct. Antennce with scape scarcely reaching 

 eye ; the two basal joints of funicle subequal. Prothorax trans- 

 verse, apex a little narrower than base, sides moderately rounded, 

 broadest about middle, anterior margin truncate and distinctly 

 reflexed, ocular lobes not very prominent. Upper surface rather 

 convex, with six regular rows of four to six long cylindrical 

 spiniform tubercles and usually a smaller and abbreviated lateral 

 row ; central furrow distinct, but shallow and without a carina ; 

 tubercles bare, each with a pale depressed seta, interstices with 

 sparse scaling ; sides of prosternum set with low granules. Elytra 

 oblongo-ovate, shoulders rounded, sides subparallel to beyond 

 middle, apical processes short, sharp, and widely separated. Upper 

 surface rather convex, with rows of large but shallow punctures, 

 often separated by intervening gianules ; interval 1 with a row of 

 scattered granules ; interval 2 with a short apical row of small, 

 but more or less strongly cristate, tubercles ; intervals 3, 5, and 7 

 with rows of small closely-set subconical tubercles, those on the 

 two former vanishing behind middle ; 4 with a few scattered 

 tubercles and a very short subcristate row on the declivity ; 6 with 

 a row of rather distant conical tubercles, abbi'eviated in the basal 

 half ; apices of tubercles bare, each with a depressed pale seta ; 

 scaling dense, earth-brown. Legs with dense brown scaling and 

 scattered pale setfe ; posterior tarsi rather narrow, the 2nd joint a 

 trifle narrower than the others, 2nd and 3rd subequal in length, 

 1st a little longer.
