282 PHYTOPHAGA.—SUPPLEMENT. 
posteriorly, depressed, closely and distinctly punctured throughout, the disc testaceous, the suture and 
lateral margin rather broadly greenish, this colour diminishing in extent posteriorly ; underside and legs 
black, shining. 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith). 
A single example. Of comparatively large size, and distinct from any other species 
from our region by the colour of the elytra and the close punctuation. 
38. Systena(?) minuta. 
Black, above metallic blue or greenish; the antenne (entirely or partly) and legs (the posterior femora 
excepted) flavous ; thorax and elytra very minutely punctured, and finely wrinkled or granulate. . 
Length ? line. 
Head finely granulate, without punctures, the frontal tubercles very small; antenne extending beyond the 
middle of the elytra in the male, flavous, the terminal two joints often fuscous, the third joint thinner and 
slightly shorter than the second, the following joints equal and rather stout, gradually thickened towards 
the apex; thorax nearly twice as broad as long, the sides rounded, the angles scarcely distinct, the base 
with a more or less well marked transverse groove not extending to the sides, the surface finely granulate 
and scarcely perceptibly punctured ; scutellum black; elytra parallel, not very convex, and scarcely more 
distinctly punctured than the thorax; legs flavous, the posterior femora piceous ; the first joint of the 
posterior tarsi as long as the following three joints together ; anterior coxal cavities closed. 
Hab. Brrvish Honpuras, R. Hondo (Blancaneaux); GuatemMaLa, Zapote (Champion) ; 
Panama, Bugaba, Volcan de Chiriqui (Champion). . 
This very small species agrees in most of its characters with Systena, but differs 
from it by the short joints of the antennz and the more transversely-shaped thorax. 
Some specimens have a nearly black thorax and dark blue elytra; those from British 
Honduras are entirely dark blue above, with an almost smooth head and thorax. Many 
examples were obtained by Mr. Champion in Chiriqui. | 
39. Systena robusta. | 
Entirely testaceous ; the antenne stout; thorax finely punctured, the basal sulcus distinct and sinuate ; elytra 
very closely and finely punctured. ; 
Length 4 lines. 
Hab. Mexico (coll. Jacoby). 
This is a large and comparatively robust species. It differs from. most of its con- 
geners by the long and stout antenne, the basal joints of which are thickened, the 
third longer than any of the following ones. The head is impunctate, broad, not 
constricted behind the eyes; the thorax is closely and finely punctured, of the usual 
shape, but with the basal groove sinuate at the middle and very distinctly marked ; the 
elytra are depressed, with the basal portion somewhat swollen, extremely closely and 
finely punctured throughout ; the underside and legs are testaceous. 
A single specimen sent me by Dr. Pipitz of Graz, without nearer indication of 
locality. |
