132 PHYTOPHAGA.—SUPPLEMENT. 
This very small species seems to be somewhat allied to S. memnonius, Suffr., but to 
differ from it in several particulars. S. minutus is apparently subject to a good deal of 
variation, not one of the five specimens obtained agreeing perfectly with each other; in 
one the pale lateral margin to the thorax is almost entirely absent and the fulvous colour 
of the elytra extends to two-thirds their length, and-in the variety noticed above the black 
colour of the elytra has entirely disappeared. The small pale spot below the eyes is 
present in all the specimens, and the strong punctuation at the sides of the thorax only 
is also constant. The prosternum is strongly punctured and its apex is subtriangular. 
25. Scolochyus cordovensis. (‘lab. XX XVIII. fig. 17.) 
Fulvous, the antenne “he basal joints excepted) black; thorax sparingly punctured; elytra moderately 
strongly puncta3s-striate, two spots at the base, placed transversely, and a narrow band below the middle 
of irregular shape, black. 
Length 12-2 lines. 
Head fulvous, impunctate, the eyes almost contiguous in the male, more distant in the female, the intermediate 
space impressed with a narrow central longitudinal groove; labrum flavous; antenne black, the two or 
three basal joints fulvous; thorax about two and a half times as broad as long, the sides rounded and 
widened at the middle, the surface very finely and rather closely punctured, the lateral portion more 
strongly punctate and with a rather deep transverse oblique depression; scutellum flavous; elytra with 
rows of rather deep punctures, the punctures at the sides and near the suture more irregularly and closely 
placed, the extreme apex impunctate, each elytron with a spot on the shoulder, a rather larger spot near 
the scutellum, a transverse band below the middle (not touching either margin and widened towards the 
suture), and the lateral margin very narrowly, black; underside entirely fulvous, clothed with very short 
yellowish pubescence. 
Hab. Mexico, Cordova (Sal/é). 
S. cordovensis differs in its elytral design from any other species of our region; 
specimens of both sexes of it are before me. 
26. Scolochrus gamma. (Tab. XX XVIII. fig. 18.) 
Flavous, the breast piceous; thorax closely punctured and finely rugose, with a Y-shaped central brown mark ; 
elytra opaque, distinctly punctured, the interstices finely wrinkled, a spot at the shoulder, two others 
below the middle, placed transversely, and a semicircular band surrounding the scutellum, piceous. _ 
Var. The elytral spot fulvous, divided, and small. 
Length 2-23 lines. 
3. Head closely and rather strongly punctured, the entire sides occupied by the large and contiguous eyes ; 
labrum bright flavous; antenne entirely flavous, extending beyond the middle of the elytra, the basal five 
joints shining, the following joints finely pubescent, opaque, and slightly widened; thorax about two and 
a half times as broad as long, rather suddenly narrowed from the middle to the apex, the dise with the 
usual oblique depression on each side, closely and strongly punctured, the interspaces finely rugose and 
aciculate, flavous, with a piceous spot placed within the lateral depression and a similarly-coloured very 
distinct Y-shaped central mark; scutellum flavous; elytra regularly and rather strongly punctate-striate, 
the space surrounding the scutellum with a few punctures only placed near the suture, and bounded 
laterally by the short first row of punctures, the following four rows placed at nearly equal distances 
from each other, but followed by a wider space, the eighth and ninth rows closely approached, the colour 
similar to that of the thorax, the interstices closely and finely wrinkled and opaque, the pattern in the 
plainly-marked specimens consisting of a semicircular narrow dark band extending across the suture 
below the base and another band below the middle, the latter being nearly semicircular in shape, but
