EUPHRYTUS. 211 
body, black, the lower three joints testaceous at the apex, the first joint short and thick, black above, the 
terminal joints elongate, but slightly thickened ; thorax transverse, the sides nearly straight, narrowed in 
front, with a narrow greenish margin, the disc finely and closely punctured, black; elytra black, with a 
large subquadrate rufous spot surrounding the shoulders, slightly depressed below the base, the disc closely 
geminate-punctate-striate, the interstices forming narrow longitudinal spaces, which become costate near 
the apex; legs and underside black ; femora unarmed. 
Hab. Mexico, Chilpancingo (H. H. Smith). A single specimen. 
13. Euphrytus (?) semirugosus. 
Elongate, dark xneous; antenne short, the apical joints thickened; thorax very closely and rather strongly 
punctured ; elytra as closely and more strongly punctured, the interstices at the sides semirugose. 
Length 2 lines. 
Head not closely but distinctly punctured on the vertex; the eyes widely separated, sinuate at the inner 
margin; labrum fulvous; terminal joint of the palpi thickened, its apex subtruncate, piceous; antenne 
(2) only extending a little beyond the base of the elytra, black, the basal joints testaceous at their apex, 
the terminal five joints thickened ; thorax twice as broad as long, the sides rather strongly rounded, the 
anterior angles slightly thickened and produced, the surface very closely punctured (especially near the 
sides), and with a more or less distinct lateral depression; elytra narrowly parallel, more strongly punc- 
tured than the thorax, the punctures arranged in very close, somewhat geminate, rows near the suture, 
but becoming irregular at the sides, the sutural interstices slightly raised in lines, the lateral inter- 
stices obscurely wrinkled; legs piceous or black; femora unarmed, their base sometimes paler; the first 
joint of the posterior tarsi as long as the following two joints together ; prosternum comparatively broad, 
not much narrowed between the coxe. 
Hab. Mexico, Refugio in Durango (Hége). 
I place this comparatively small species, of which only female specimens seem to 
have been obtained, in Kuphrytus, as it agrees with the members of that genus in its 
general shape; it differs, however, from the allied forms in the short and thickened 
antenne, the short metatarsus of the posterior legs, and the broader prosternum. 
E. semirugosus may be known by its small size, short antenne, and semirugose lateral 
interstices of the elytra. 
14. Euphrytus apicicornis. (Tab. XL. fig. 16.) 
Greenish-zneous, the antennae (the apical three joints excepted), elytra, and legs fulvous; head and thorax 
finely and closely punctured; elytra rather regularly punctate-striate; femora unarmed. 
Length 3 lines. 
Head finely and rather remotely punctured on the vertex, the lower portion and the clypeus more strongly and 
closely punctured ; the latter wedge-shaped, bounded on each side by a smooth triangular space; labrum 
and mandibles fulvous; antenns two-thirds the length of the body, fulvous, the basal joints very slender, 
the apical three joints fuscous ; thorax about one half broader than long, the sides very slightly rounded, the 
anterior angles thickened, the surface closely and finely punctured, greenish-zeneous, somewhat depressed 
near the posterior angles; scutellum metallic swneous; elytra nearly parallel, slightly transversely 
depressed below the base, reddish-fulvous, the punctuation stronger than that of the thorax, and arranged 
in close and rather regular rows, the interstices forming narrow, somewhat raised, smooth longitudinal 
spaces; underside dark wneous, the last abdominal segment obscure fulvous; legs fulvous; the first joint 
of the posterior tarsi as long as the following three joints together ; prosternum narrowly elongate. 
Hab. Mexico, Ciudad in Durango (Forrer). 
Of this distinct species only one specimen was obtained ; the colour of the antenne,
