174 SCAPHIDIIDA. 
base, moderately and distinctly punctured, with the interstices smooth and shining; sides moderately 
rounded and margined ; basal margin not sinuated, produced towards the scutellum, with the angles acute. 
Scutellum covered by the thorax. lytra rufo-testaceous, with the disc more or less dusky, rather longer 
but scarcely broader than the head and thorax, widest near the shoulders, rather deeply and very closely 
punctured; almost asperated, sides margined, but scarcely rounded; extremities rather broad and mode- 
rately rounded. Abdomen moderate, rufescent. Leys very long, yellow. Underparts testaceous, with 
the pectus dusky. 
Hab. Guatemata, Zapote, Capetillo (Champion). 
Differs from S. dunatum in its less convex form, much deeper sculpture, dusky pectus, 
and generally in the dusky disc of the elytra. 
5. Scaphisoma luteipes. 
Scaphisoma luteipes, Oberthiir, Col. Nov. i. p. 15 (1883) °. 
“ Ovale, sat latum, convexum, nitidum, piceum, apice tenuiter luteo-marginatum, pedibus antennisque flavidis 
vel testaceis, subtiliter punctulatum. Elytra validius cribrata, stria suturali minuta basi subarcuata. 
Long. 13 millim. ; lat. 11 millim.” 
Hab. Panama, Matachin (Zhiéme 1). 
“ Ovale, convexe, assez élargi, luisant, noir avec l’extrémité inférieure des élytres finement rebordée de jaune, 
les pattes et les antennes de cette méme couleur. Corps trés-finement ponctué en dessus ; élytres pour- 
vues d’une ponctuation plus forte, avec une fine strie suturale 4 peine visible légérement arquée a la base. 
“Nous possédons deux exemplaires de cette espéce, qui sont en entier d’une couleur testacée ; probablement 
ces exemplaires sont immatures. 
** Voisin de S. terminatum, mais plus petit.” 
The coarse punctuation of the elytra separates S. /utetpes from the other species here 
enumerated. ‘The diagnosis gives ‘ piceous’ as the colour, though the two examples 
are subsequently stated to be entirely testaceous.
