252 PHYTOPHAGA.—SUPPLEMENT. 
36. Zygogramma thoracica. (Tab. XLI. fig. 12.) 
Black; the thorax pale fulvous, the basal margin broadly marked with black, the dise impunctate ; elytra 
flavous, a sutural stripe (divided anteriorly), two stripes on the disc, and the posterior portion of the 
lateral margin, black. 
Length 33 lines. 
Head black, closely punctured near the eyes ; palpi black, the terminal joint not longer than the preceding 
one; antennee black, the terminal five joints pubescent, thickened, the others shining, the four or five 
basal joints obscure fulvous ; thorax about twice as broad as long, rather strongly widened at the middle, 
the sides straight at the base, rounded in front, but scarcely produced at the apex, the disc with a few 
minute punctures, the lateral portion and base more closely and strongly punctured, pale fualvous, the 
lateral and apical margins very narrowly, the basal margin broadly black; scutellum black; elytra 
punctate-striate along the inner and outer margins of the dark stripes only, for the rest irregularly 
punctured, flavous, a narrow sutural stripe (divided below the base), two broader stripes on the disc 
(the inner one the shortest, the outer one not extending to the apex), and the lateral margin from the 
middle to the apex, black ; underside and legs black with a bluish gloss, strongly punctured. 
Hab. Mexico, Durango city (Hége). 
A single specimen. Evidently allied to Z. rustica (Stal), but differing in the black 
palpi, the divided sutural stripe, and the colour of the lateral margin of the elytra; 
the basal black band of the thorax is strongly concave on its anterior edge. 
STILODES (p. 221). 
— Stilodes ceelebs (p. 223). 
To the localities given, add :—-Mexico, Ventanas, Acapulco (Hége). 
14, Stilodes quadristriata. (Tab. XLI. fig. 13.) 
Black ; head flavous ; thorax sparingly punctured, the sides flavous ; elytra distantly striate-punctate, flavous, 
each with a black subsutural and a submarginal stripe. 
Var. One of the elytral stripes obsolete or entirely absent. 
Length 34—4 lines. 
Head with a few fine punctures, flavous; the terminal joint of the palpi scarcely shorter than the preceding 
one; antenne rather slender, the terminal joints but slightly thickened, black, the basal joints stained 
with flavous beneath ; thorax about twice as broad as long, the sides nearly straight, the anterior angles 
not very prominent and rather blunt, the disc with some scattered punctures, black, the sides flavous ; 
scutellum black ; elytra wider at the base than the thorax, parallel, each with about seven rows of fine 
punctures, the fourth and fifth rows much more widely separated than the others, the disc flavous, a 
narrow black slightly curved stripe placed close to the suture (not extending to the apex) and a similar 
stripe occupying the space between the fifth and sixth rows of punctures, the outer stripe extending nearly 
to the suture ; underside and legs black. 
Hab. Panama, Volcan de Chiriqui 4000 feet ( (Champion). 
More than a dozen specimens were obtained by Mr. Champion, who states that the 
species inhabits the dense forest only. When the insect is alive the elytra are of a 
brilliant metallic golden colour, resembling in this respect many of the Cassidide. 
LEPTINOTARSA (p. 227). 
Leptinotarsa chalcospila (p. 227). 
To the locality Mexico, add :—Tacambaro in Michoacan (Hége), Huetamo (Flohr).
