with a band of dense brown scaling ; foiebead bare, impunctate, 

 broadly and deeply impressed ; anteocular furrows deep, but 

 invisible from above. Rostvam continuous in the same plane as 

 forehead, as long as head and prothorax ; in profile, the upper 

 edge is straight to beyond middle and then sharply declivous. 

 Upper su.rface with a bi'oad but shallow centi-al furrow thi-oughout 

 (almost obliterated about middle), faintly punctui-ed and with 

 short setiform scaling ; uppei- lateral sulci faint, but evidently 

 uniting at base, lowei- pair rather shoi'tei- but much deeper; 

 scrobes directed beneath base of rostrum ; infei'ior basal furrow 

 absent. Antennce with scape not nearly reaching eye ; the two 

 basal joints of funicle subequal. Prothorax as long as broad, 

 apex a little nai-rower than base, sides rounded, broadest rathei- 

 behind middle, apical margin truncate, ocvilai- lobes well deve- 

 loped. Upper surface almost plane, with a broad discal, and 

 nariower lateral, low of low rounded tubercles on each side of 

 central furrow, which latter contains a distinct carina ; tubei'cles 

 bare, each with a veiy short seta ; among the tubeicles the scaling- 

 is brown, but greyish white in the smooth spaces. Elytra ovate, 

 shoulders sloping, sides gently rounded, broadest about middle, 

 apical processes in $ long, thick, and subcontiguovis. Uppei- 

 surface convex, with regular rows of very small punctui-es ; 

 intervals 1, 4, and 6 devoid of tubercles ; 3, 5, and 7 with complete 

 rows of very small, closely placed tvibei-cles, sometimes duplicated 

 and subcatenulate towards base ; interval 2 with only a short sub- 

 cristate row of similar tubercles on the declivity ; intervals 1 to 3 

 and the upper part of inflexed margin with thin brown scaling ; 

 intervals 4 and 6 and the edge of inflexed margin with broad 

 stripes of dense greyish- white scaling ; the brown scales distinctly 

 narrower than the white. Legs with sparse pale setse. forming a. 

 denser ring near apex of femoiu ; posterior tarsi with the joints 

 of about the same width, 2nd and 3rd subequal in length, 1st 

 rather longer.

Type in South -African Museum. 



An apparently i-ai-e species, representing in the Transvaal the- 

 Western sexvittattcs F. ; but the latter is a much narrower and 

 more parallel-sided insect, and its very prominent eyes, with the 

 correlated feeble development of the ocular lobes, constitute a very 

 distinctive character.
