Matthews enumerated thirteen species of this well-known 
genus from Central America. The following new form was 
subsequently received from the Guerrero mountains. 
*Scaphisoma occidentale, n. sp. 
Oblong-elliptic, very shining, pitchy-black, the labrum, palpi, 
and antennae, the tip of the pygidium, the ventral segments in 
part, and the tarsi testaceous or rufo-testaceous, the outer five 
joints of the antennae slightly infuscate, the femora and tibiae rufo- 
piceous; the punctures of the upper surface each bearing a rather 
long, fine, adpressed, blackish hair. Head and thorax very sparsely, 
minutely punctulate, the elytra with a much more distinct scattered 
punctuation; antennae sparsely setose, joints 3-6 very slender, 
3 and 4 short, 4 longer than 3, 5 as long as 3 and 4 united, 
6 elongate, equalling 3-5 united, 7-11 long, subequal, arcuately 
widened within; thorax (as seen from above) arcuately narrowed 
from the base; elytra rounded at the sides anteriorly, abruptly 
truncate at the apex, obliquely depressed just before the tip, the 
sutural stria deep; legs very elongate. 
Length 3, breadth 14 mm. 
Hab. Mexico, Omilteme in Guerrero, 8,000 feet (H. H. 
Smith). 
One specimen. Narrower and smoother than S. thoraci- 
cum, Matth., the elytra more distinctly punctate, the femora 
and tibiae rufescent. The minute black, adpressed hairs, 
which are only visible under the microscope, and soon 
abraded, make the elytral interstices appear obliquely or 
longitudinally strigose. They are probably also present 
in S. thoracicum. The N. American S. castaneum, Motsch., 
seems to be another allied less elongate form, with more 
closely punctured upper surface.
