78 PHYTOPHAGA.—SUPPLEMENT. 
The close and irregular punctuation of the elytra and their fine pubescence at once 
separate this species from its allies. 
10. Euryscopa semistriata. (Tab. XXXVII. fig. 4.) 
Subcylindrical, black, finely pubescent; elytra closely and rather irregularly punctured, with longitudinal 
rows of larger punctures, finely pubescent, a subquadrate spot at the shoulders reddish-fulvous. 
Length 24 lines. 
Hab. Muxico, Durango city (Hége). 
Like Z, villosa, the present species (of which only a single example was obtained) 
has the elytra finely pubescent and the punctures closely and rather irregularly placed ; 
the punctuation is, however, finer than in Z. villosa, and interrupted by more regular 
rows of closely placed deeper punctures; the red shoulder-spot is very small, almost 
quadrate, and occupies the humeral callus. In all these details #. semistriata differs 
from Z. villosa. The size is also smaller ; the antenne do not extend to the base of 
the thorax, and have, as usual, the second and third joints fulvous; the thorax is twice 
as broad as long, finely punctured, and clothed with long white pubescence; and the 
legs are entirely black. The punctuation of 2. semistriata does not seem to me to be 
irregular enough to place the species in Coscinoptera. 
11. Euryscopa longicollis. (Tab. XX XVII. fig. 5.) 
Narrowly elongate, black ; head, thorax, scutellum, and underside densely pubescent; elytra each with a small 
red humeral spot, closely and strongly punctate-striate, the interstices longitudinally costate. 
Length 22 lines. 
Head elongate, closely and finely punctured, and clothed with long white pubescence; eyes moderately large ; 
the labrum and mandibles black; antenn# extending only to the middle of the thorax, black, the 
second and third joints fulvous; thorax elongate, about one half broader than long, subcylindrical, the 
sides strongly deflexed, the surface very closely and rather finely punctured, clothed (like the head) 
with long white pubescence ; scutellum pubescent; elytra narrowed posteriorly, with closely-arranged 
rows of transversely-shaped punctures, the interstices narrowly but distinctly costate (especially near 
the apex), the shoulder with a small subquadrate red spot; femora black, the apex of the tibie obscure 
fulvous. 
Hab, Mexico, Northern Sonora (Morrison). 
This species and /. parvula were both labelled #. lecontet by Morrison, although 
certainly quite distinct from each other as well as from Z. lecontei ; Crotch, in his short 
description of the latter, says that the thorax is coarsely punctured. In #. longicollis 
the thorax is decidedly elongate; the interstices of the elytra are costate, and the punc- 
tures transverse ; and the red shoulder-spot only extends to the third stria, and leaves the 
callus black: these characters, together with the narrowly elongate and comparatively 
large size, will assist in the recognition of the species. 
Only a single specimen was sent.
