126 PHTTGPHAGA. 



Head extremely finely punctured; eyes very prominent; labrum fulvous ; antennae more than half the length 

 of the body, the third and fourth joints of equal length and double as long as the second, the terminal 

 joints gradually widened ; thorax about twice as broad as long, slightly narrowed towards the apex, and 

 anteriorly deflexed, the anterior angles slightly thickened, posterior margin very little widened at the 

 middle, surface of a subopaque silky appearance, impunctate ; elytra more shining, very finely and rather 

 obsoletely punctured at the disk, more distinctly towards the sides, the puncturing arranged in indistinct 

 striae, extreme apex with a short costa ; legs and tarsi fulvous ; femora slightly widened, but not dilated ; 

 claws appenfliculate. 



Var. Above metallic blue. 



Hab. Mexico, Yolos, Juquila (Boucard, coll. Salle), Guanajuato (Duges, coll. SalU). 



In this species the femora are not dilated ; and this almost necessitated the erection 

 of another genus ; but as the thickened antennse and narrow truncate prosternum 

 agree with the other generic characters, I have, for the present, included this small 

 species, which may be recognized by its opaque thorax, in the present genus. 



4. Euphrytus Mvicollis. (Tab. VIII. fig. 19.) 



Elongate, convex, fulvous ; last four joints of the antennas black ; elytra greenish aeneous, finely subpunctate- 

 striate, the interstices extremely finely granulate. 



Length 2| lines. 



Head convex, extremely finely punctured, fulvous ; elypeus triangular, its anterior margin slightly concave ; 

 antennae two thirds the length of the body, filiform, the last joints widened, somewhat hatchet-shaped, 

 fulvous, last four joints black ; thorax very transverse, the sides widened towards the base, then subangulate 

 to the latter, surface subopaque, fulvous, covered with minute punctures, which are only visible under a 

 strong lens ; scutellum fulvous ; elytra not wider at the base than the thorax, rather convex, finely but 

 much more distinctly punctured than the other parts, the punctuation arranged in subregular close 

 lines, the minutely granulate interstices giving the whole a silky-like appearance ; underside (with the 

 exception of the middle of the abdomen, which is piceous) and the legs fulvous ; posterior femora trian- 

 gularly dilated ; anterior tarsal joint in the male widened. 



Hob. Mexico, Cuernavaca, Capulalpam, Puebla (Salle), Juquila, Oaxaca (Boucard, 

 coll. Salle). 



The fulvous head and thorax, together with the silky-like appearance of the elytra 

 and its fine punctuation, distinguish this species at first sight ; the terminal joint of 

 the palpi is obliquely truncate, as in the other species. 



COYTIEEA. 



Coytiera, Lefevre, Rev. et Mag. de Zool. 1875, p. 116. 



A single species served M. Lefevre for the erection of this genus, which greatly 

 resembles again Chalcophana and Euphrytus. With the latter genus it has the truncate 

 base of the prosternum in common, but differs in the more rounded shape of the sides 

 of the thorax, the simple femora, and the more slender antennae. 



The type is from Cayenne. 



1. Coytiera Mvipes. (Tab. VIII. fig. 15.) 



Oblong, greenish black below, aeneous above ; antennae filiform, fulvous ; thorax finely, elytra strongly punctate- 

 striate ; legs fulvous.
