210 PHYTOPHAGA.—SUPPLEMENT. 
Head closely and distinctly punctured; eyes large and prominent, sinuate; antenne two-thirds the length of 
the body, flavous, the third and fourth joints equal; thorax about one half broader than long, the sides 
rounded and slightly sinuate, the surface extremely minutely and closely punctured, flavous ; scutellum 
with a few fine punctures; elytra rather strongly and closely punctured, the punctures arranged almost 
in double rows, the interstices transversely rugose at the sides, slightly raised in narrow lines on the disc, 
these lines being more strongly raised and broader at the apex ; femora unarmed ; the first joint of the 
posterior tarsi as long as the following three joints united; prosternum narrowly elongate. 
Hab. Muxico, Iguala in Guerrero (Hége). 
A typical species, recognizable at once by the entirely flavous colour. 
10. Euphrytus nigritarsis. 
Fulvous, the antenne (the three basal joints excepted), the apices of the tibie, and the tarsi black; thorax 
extremely closely and finely punctured; elytra metallic green, subgeminate-punctate-striate, the inter- 
stices slightly raised. 
Length 3 lines.

. Head finely and rather closely punctured; antenne black, the lower three joints fulvous, the terminal 
joints gradually thickened ; thorax scarcely twice as broad as long, the sides slightly sinuate, narrowed in 
front, with a narrow flattened margin, the surface extremely finely and closely punctured throughout ; 
scutellum fulvous; elytra with closely arranged double rows of strong punctures, separated by narrow 
longitudinal smooth spaces, metallic green; underside and legs fulvous, the apices of the tibis and the 
tarsi black; femora unarmed. 
Hab. Mexico, Chilpancingo in Guerrero (Hége). 
11. Euphrytus elongatus. (Tab. XL. fig. 14.) 
Elongate, blackish or purplish-sneous ; thorax closely and finely rugose; elytra strongly and closely geminate- 
punctate-striate, the interstices longitudinally raised. 
3. Antenne robust, the terminal joints gradually widened and flattened; the posterior femora obsoletely

angulate. 
. Antenne much shorter, the joints scarcely widened ; the posterior femora simple. 
Length 3 lines. 
dé. 
Head rugosely punctured; the antenne robust, two-thirds the length of the body, the first joint short, 
nearly subquadrate, piceous above, the second joint very short, the third and fourth joints fulvous, the 
third widened at its apex and much shorter than the fourth, the following joints subtriangularly widened, 
black, the apical one concave and sinuate at its apex; thorax about one half broader than long, the sides 
rounded, narrowed in front, the surface very closely punctured and finely rugose throughout ; elytra with 
strong double rows of punctures, divided by longitudinal narrow raised lines; the first joint of the posterior 
tarsi as long as the following two joints united, the claw-joint very long and slender. 
Hab. Mexico, Durango city (Hoge). 
The colour of this very elongate and narrow species is dull black, purplish, or eeneous ; 
the general shape, the structure of the antenne in the male, the rugosely sculptured 
thorax, and the semicostate elytra separate E. elongatus from any of its allies. 
12. Euphrytus humeralis. (Tab. XL. fig. 15.) 
Elongate, black, the basal joints of the antenne testaceous; thorax closely and finely punctured; elytra 
subgeminate-punctate-striate, black, a large subquadrate spot at the shoulders rufous. 
Length 3 lines.
