CRYPTOCEPHALUS. . 115 
seventh rows only indicated by a few punctures, the interstices between the eighth and following rows 
convex; underside black; the anterior legs, the base of the posterior femora, and the tibie and tarsi, flavous. 
Hab. Panama, Volcan de Chiriqui (Champion). 
The bright metallic blue colour, the finely punctured thorax, and the colour of the 
legs distinguish C. celestinus from several small metallic species inhabiting South 
America. 
46. Oryptocephalus sculptilis. 
Flavous; thorax closely punctured, the disc obscure piceous; elytra very closely and deeply punctured, the 
interstices convex, the space between the fifth and eighth rows also deeply and irregularly punctured, all 
the punctures piceous. 
Length 2} lines. 
Head closely and strongly punctured, with a central darker mark; antenna two-thirds the length of the body, 
entirely fulvous; thorax at the base twice as broad as long, of half the width anteriorly, the posterior 
margin finely serrate and very narrowly black on the extreme edge, the surface closely and finely, but 
somewhat irregularly, punctured, piceous, the margins flavous; scutellum flavous, margined with black ; 
elytra flavous, the punctures very deep and closely placed, piceous, the first row joined to the second 
below the middle, the third and fourth rows united at the apex, the fifth row curved outwards near the 
apex and there joined to the eighth, the intervening space impressed with transversely placed and other 
deep punctures and above the middle by another transverse row of punctures which interrupts the short 
sixth row below the shoulder, the seventh row entirely absent, the interstices longitudinally costate ; 
underside finely pubescent, flavous, the breast darker; the legs fulvous, the femora with a flavous spot at 
the apex. 
Hab. Mexico, Ventanas in Durango (Hége). A single specimen. 
From the large-sized pallid unicolorous species inhabiting our region C. sculptilis 
differs in the sculpture of the elytra, the punctures being deep, closely placed, and of 
rather transverse shape, and the interstices longitudinally convex; the space between 
the fifth and eighth striz is also closely punctate. 
In the last-mentioned character C. sculptilis differs from all other species of the 
genus known to me. 
47. Cryptocephalus graphipterus. 
Piceous; thorax fulvous, the margins and two spots at the base pale yellow; elytra flavous, strongly punctate- 
striate, a sutural stripe, narrowed posteriorly, piceous, 
Var. Elytral stripe dark metallic green. 
Length # line. 
Head flavous, a central stripe between the eyes and the parts of the mouth brown; antenney black, the basal 
four joints flavous, the terminal joints slightly thickened ; thorax twice as broad as long, the surface finely 
punctured, fulvous, the margins narrowly and two small oblique spots at the base flavous; scutellum 
elongate, raised ; elytra with uninterrupted and strong rows of punctures, the sixth row consisting of a 
few punctures only ; the seventh row entirely absent, the interstices at the sides convex, the surface 
flavous, a small spot at the shoulders, a stripe along the suture (pointed at the apex) and the lateral 
margins, piceous ; underside fulvous, i one example stained with piceous ; legs fulvous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith).
