114 PHYTOPHAGA.—SUPPLEMENT. 
of the specimens vary to any perceptible degree ; the regularity of the elytral strie, 
with only an indication of the seventh row at the shoulder, the raised interstices, and 
ihe absence of any markings (a small brown spot at the shoulder excepted), as well as 
the uniformly flavous or pale fulvous colour, will help to distinguish C. inconspicuus. 
Cryptocephalus zapotensis (p. 56). 
To the localities given, add:—Mexico, Tapachula in Chiapas (Hoge); GUATEMALA, 
San Isidro, Chacoj (Champion). 
Cryptocephalus auratus (p. 57). 
To the localities given, add:—Mexico, Saltillo in Coahuila (Dr. Palmer), Xucuma- 
natlan and Chilpancingo in Guerrero (H. H. Smith), Orizaba (Sallé); Panama, Volcan 
de Chiriqui, Pefia Blanca (Champion). 
42 (a). Cryptocephalus amulensis. 
Black, above dark metallic blue, the basal joints of the antenne and the tibiee and tarsi obscure fulvous ; thorax 
impunctate ; elytra finely punctate-striate, with two tubercles below the shoulders, the interstices convex 
at the sides. 
Length 1 line. 
Head with its lower portion rather deflexed, obscure piceous, the space near the eyes marked with flavous, the 
intraocular space impressed with a distinct longitudinal groove; antenns with the three or four basal 
joints flavous beneath, piceous above (the last five joints wanting); thorax twice as broad as long, convex, 
the sides rounded, the surface entirely impunctate ; scutellum slightly longer than broad, without basal 
fovea ; elytra cylindrical, of a lighter blue tint than the thorax, finely and regularly punctate-striate on 
the disc, the rows of punctures interrupted below the shoulders by a short transverse tubercle, the latter 
followed by a short, oblong, strongly raised ridge, the outer interstices also longitudinally costate ; 
prosternum longer than broad, its posterior margin produced at each angle into a point. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
Although only a single female specimen of this insect was obtained, the curious and 
almost unique sculpture of the elytra will readily distinguish C. amulensis; the punc- 
tures are plainly visible on the middle of the disc, but very obscure at the sides, and 
the short and more elongate tubercles are isolated and strongly marked. 
45. Cryptocephalus ccelestinus. 
Below black, above metallic blue, the base of the antennz, the anterior tibia, and the base of the femora 
flavous; thorax extremely finely punctured; elytra finely punctate-striate, the sixth and seventh strie 
obsolete. 
Length 2 line. 
Head depressed between the eyes, dark blue, the labrum fulvous, the clypeus much broader than long ; antenne 
scarcely half the length of the body, the lower five joints fulvous, the others black, the terminal joints 
distinctly widened ; thorax twice as broad as long, the sides nearly straight, narrowed in front, the poste- 
rior angles acutely produced, the surface extremely minutely punctured (the punctures only visible under 
a strong lens) and with a narrow and obsolete transverse groove in front of the basal lobe; scutellum 
not raised, as broad as long, dark blue; elytra finely and rather regularly punctured, the sixth and
