306 .PHYTOPHAGA.—SUPPLEMENT. 
Blepharida may prove to be varieties of one or other of these; but till further material 
is obtained, it is impossible to speak with any certainty. I have already stated my 
opinion (huj. op. p. 384) that W. sparsa ought to be placed in Blepharida. 
BLEPHARIDA (p. 385). 
12. Blepharida alternata. (Tab. XLII. fig. 18.) 
Fulvous, the apical joints of the antenne fuscous ; thorax very finely punctured, with several depressions ; 
elytra geminate-punctate-striate, pale flavous, the dise Jongitudin ally striped with fulvous, the shoulders 
with an oblong darker spot. 
Length 3 lines. 
Head nearly impunctate, with a transverse groove between the eyes, the latter elongate ; antenne inserted at 
some distance from the inner margin of the eyes, less than half the length of the body, fulvous, the last 
three or four joints fuscous, the third and fourth joints equal, the fifth the longest, the following joints 
shorter; thorax nearly three times as broad as long, the sides almost straight, the anterior margin 
concave, the surface with a few punctures at the sides only and two fovee at the same place; elytra 
convex, deeply and closely gemminate-punctate-striate, the disc fulvous, this colour divided by very narrow 
longitudinal pale flavous stripes, the sutural and lateral margins more broadly of that colour, the shoulders 
with an oblong obscure fulvous spot. 
Hab. Mexico, Xucumanatlan in Guerrero (H. H. Smith). 
A single specimen. 
CYRSYLUS. (To follow the genus Pseudogona, p. 391.) 
Ovately-subquadrate ; antenne filiform, the terminal joints slightly thickened ; palpi slender; eyes large ; 
thorax transversely subquadrate, without transverse sulcus; elytra punctate-striate ; tibie simple, the 
posterior pair mucronate ; prosternum rather broad, flattened, longer than broad ; anterior coxal cavities 
closed ; claws appendiculate. 
This genus is proposed for several small species which agree in some respects with 
Systena, but differ from it by the thorax being without trace of a transverse sulcus, and 
by the elytra being punctate-striate; the eyes are also larger than in Systena, and the 
thorax is scarcely broader than long and of different shape. C. recticollis appears to be 
one of the commonest and most widely distributed species of Halticine in Central 
America. 
1. Cyrsylus recticollis. (Tab. XLII. fig. 16.) 
Black or piceous ; the antenne and the four anterior legs more or less fulvons ; ; the head impunctate ; the 
thorax extremely finely punctured, subquadrate; elytra finely and regularly punctate-striate. 
Var. a. Thorax fulvous, the elytra more or less piceous. 
Var. b. Entirely fulvous or testaceous. 
Length 13-14 line. 
Head impunctate, the frontal elevations in the shape of narrow oblique ridges, the carina very short; antenne 
ratber short, not extending to the middle of the elytra, fulvous, the terminal joints more or less fuscous, 
the second joint as stout as but only half the length of the first, the third and fourth equal, the following 
joints gradually thickened; thorax one half broader than long, the sides perfectly straight, the anterior 
angles oblique, the surface without depression, with a few minute punctures at the sides and near the 
base, for the rest impunctate, the base distinctly margined ; scutellum small, triangular ; elytra broader at
