162 SCAPHIDIID. 
Jalapa, Chilpancingo (Hége); British Honpuras, R. Sarstoon, Belize (Llancaneauz) ; 
GuaTEMALA, Zapote, San Gerdnimo, Chacoj (Champion). 
This variable species was at first mistaken by me for the Colombian S. rubicundum, 
Reitt., and is so named on our Plate. It is distinguished by its very convex and 
shining surface, deeply depressed at the suture, no basal row of punctures on the 
thorax, deep and abbreviated humeral row on the elytra, and bright red colour. The 
legs vary in colour, the tibie and sometimes the femora also being often black. The 
different forms were collected together at Jalapa and Cordova; and with the long series 
of specimens before me I am unable to distinguish more than one species. ‘The authors 
cited above give the femora and tibiz as black, and the tarsi red. An example from 
Belize with entirely red legs is figured.

Body ovate, slightly depressed, very shining, remotely and indistinctly punctured, with the whole surface 
alutaceous, entirely flavescent. Head moderate, moderately punctured; eyes very large and rather 
prominent ; antenn moderate, dusky yellow, with the club large and black. Thorax large, widest at the 
base, indistinctly and remotely punctured; basal row of punctures wanting; sides slightly margined and a 
little rounded ; basal margin sinuated, produced towards the scutellum, with the angles acute. Scutellum 
very small, subtriangular. Hlytra rather broader but not longer than the head and thorax, widest before 
the middle, rather closely but indistinctly punctured; humeral row of punctures deep and close, joined to 
the suture by an impressed line; sutural stria deep and distinctly punctured ; sides slightly margined ; 
extremities moderately rounded. Abdomen acuminate, flavescent. Legs very long and slender, flavescent, 
with the apex of the femora and whole of the tibiew black. Underparts entirely yellow. 
Hab. Nicaracua, Chontales (Janson); Panama, Matachin (Thieme '). 
Differs from S. mexicanum and S. unicolor in its large size, absence of the basal row of 
punctures from the thorax, very long legs with black tibiz, yellow colour, and alutaceous 
sculpture.
