10 y\i. II. Scutt on Covy\oi)]i\i]io from the 



Colour : tliorax pitcliy blade, witli front margin rather 

 broadly recklisli testaceous ; elytra pitcliy blade, with two 

 l)road transverse redcli.sli-yellow fascite, the anterior or both 

 ot" which may be narrowly inlerrnpted by darker colour at 

 t!ie suture, thus almost foiniing tour scjKirate marks; in one 

 example the scutellum is included in the anterior pale fascia, 

 in another it is darker; metasterniiui and fiist abdominal 

 segment pitchy black, posterior segments paler; underside of 

 thorax, legs, and antennas reddish yellow, clubs of the an- 

 teinife not black, lliorax and ch/fra closely and veiy finely 

 })unetured, the punctures twice their own diameter, or rather 

 more, apart ; the thorax has no distinct b:\sal series, but au 

 impressed line immediately before the base ; sntural stria 

 present but vanishing in nearly the anterior \ ; lateral mar- 

 gins of elytra reflexed through about | the length from the 

 shoulder, visible from directly above. Wings apparently 

 ample, but not dissected out. Metasternum and abdomen 

 finely and closely punctured and pubescent. 



Frosternum (1^1. T. fig. G) much longer tlmii in Saciuvi 

 picaultiaiium, forming in front of eacli coxa a bridge about 

 lialf as broad in an antero-posterior direction as the dimen- 

 sions of the coxaj in the same direction, and having a 

 sharply elevated median longitudinal keel. A balsam- 

 ])reparation of the mouth-parts shows that the mentavi 

 (PI. I. fig. 5) is broader, not j)ointed in front, more like 

 ilatthews's figure (pi. i. DC). 



Several species resemble this in general scheme of colour, 

 but its pubescent surface distinguishes it in many cases, and 

 I have seen none veiy closely similar to it. Among the 

 other Seychelles si)ecies it is abundantly distinct from 

 b. ]>icaul(uinum by its pubescence, its narrower form, finer 

 ]>unctuation, longer prosternum, by the confluence of the 

 light U'arks on the elytra to form transverse fascial, &c.
