298 PHYTOPHAGA.—SUPPLEMENT. 
rounded, the surface very finely and closely punctured, not very shining, greenish; elytra not more 
strongly punctured than the thorax, the punctures arranged in very close rows, a sutural band (gradually 
narrowed towards the base and apex), and the lateral and apical margins narrowly, greenish. 
Hab. Mexico, near the city (H. H. Smith), Guanajuato (Sallé). 
In this species the elytral vitta occupies almost the entire disc, leaving the margins 
only greenish ; the male has the fourth joint of the antenne dilated. 
10. Phyllotreta subrugosa. 
Elongate, black, the basal joints of the antenne and the base of the tibie fulvous; head and thorax eneous, 
closely punctured; elytra metallic greenish-blue, closely punctured, the interstices finely rugose. . 
Length 1 line. . 
Head greenish-eneous, very minutely punctured, the space between the antennz swollen, longitudinally grooved ; 
antenne more than half the length of the body, the basal five joints fulvous, the first stained with piceous 
above, the apex of the fifth and of the following two joints fuscous, the rest entirely of that colour, the fifth 
joint slighter longer than either the preceding or following one; thorax about one half broader than long, 
the sides rounded, the surface greenish-sneous, finely and rather closely punctured; elytra slightly 
widened towards the middle, very closely punctured, the punctures partly arranged in double rows which 
are separated by very faint longitudinal grooves, the interspaces very finely rugose when viewed laterally ; 
the base of the tibie and the tarsi fulvous. 
Hab. Mexico, near the city (H. H. Smith). 
A single specimen. Evidently allied to P. eneicollis, Crotch, but with the elytra 
differently sculptured and the legs (the tarsi and the base of the tibisee excepted) black. 
11. Phyllotreta ——? 
Hab. Mexico, Guanajuato (Sallé), Teapa in Tabasco (H. H. Smith). 
Some specimens of a Phyllotreta from these localities are perhaps referable to 
P. albionica, Lec., or P. pusilla, Horn. They are of elongate, depressed shape, and 
of a uniform brownish-sneous colour. 
_~LONGITARSUS (p. 372). 
Longitarsus subcinctus (p. 373). 
To the Mexican localities given, add:—Atoyac in Vera Cruz (H. H. Smith). 
L. heliophyti, Horn, according to the description, seems to me not to-differ from 
LL, subcinctus. Its food-plant Helotropium (Heliophytum) indicum, Linn., occurs in 
Mexico and Central America (cf. Biol. Centr.-Amer., Bot. ii. p. 375). 
3 (a). Longitarsus ovipennis. 
Ovate, apterous, above dark piceous; the antenne fuscous, with the three or four basal joints fulvous ; thorax 
impunctate ; elytra ovate, very finely punctured in rather distantly placed rows ; legs fulvous, the posterior 
femora piceous. 
Length 3-1 line. 
Hab. Mexico, Chilpancingo and Omilteme, both in Guerrero (H. H. Smith).
