410 PHYTOPHAGA. 



6. (Edionychis frontalis. (Tab. XXIII. fig. 14.) 



Oblong, parallel, fulvous ; antennae black, short ; vertex of the head metallic green ; thorax impunctate ; elytra 

 metallic green, extremely finely and closely punctured. 



Length 2|-3 lines. 



Head closely and distinctly punctured near the inner margin of the eyes, metallic dark green, the frontal 

 tubercles and the clypeus fulvous ; antennae not extending much further than the base of the thorax, all 

 the joints short and subtriangular ; thorax transverse, dark fulvous, the sides slightly rounded, the anterior 

 angles acute, but not mucronate, the surface impunctate, the sides slightly swollen before the margin ; scu- 

 tellum black ; elytra dark green, very minutely and closely punctured ; underside fulvous, the anterior legs 

 sometimes piceous, the metasternum black. 



Hab. Guatemala, near the city (Champion), Yzabal (SallS). 



Three specimens. This species is not difficult to recognize, on account of the short 

 antennae, the colour of the clypeus and tubercles in connection with the almost rugosely 

 punctured sides of the head, and the finely punctured elytra. 



7. (Edionychis forreri. 



Oblong, black ; thorax, femora, and the two last abdominal segments, fulvous ; anterior angles of the thorax not 

 produced ; elytra green, subopaque, semirugose-punctate. 



Length 3| lines. 



Head entirely black, impunctate, with the exception of a few punctures near the eyes ; palpi and antennae 

 black, the fourth joint of the latter longer than the preceding joint ; thorax impunctate, fulvou3, not more 

 than two and a half times broader than long, the sides very narrowly flattened, the anterior angles blunt 

 and not produced ; scutellum piceous ; elytra not much widened behind, closely semirugose-punctate ; 

 underside, the tibiae and tarsi, black ; the femora and the last two abdominal segments, fulvous. 



Hab. Mexico, Ciudad in Durango 8100 feet (Forrer). 



A single specimen, distinguished by the shape of the thorax in connection with the 

 general coloration. This species may be known from (E. mexicana by the rugosely 

 punctured elytra and generally more elongate shape. 



8. (Edionychis modesta. 



Oblong-ovate, subdepressed, black ; above dark blue, green, or brownish, subopaque, or moderately shining, 

 scarcely visibly punctured. 



Length 2-2| lines. 



Head strongly and rugosely punctured between the eyes, without any frontal elevations, but with a short 

 central groove ; antennae black, short, the joints rather broader than long ; thorax with the sides nearly 

 straight, narrowly margined but not flattened, the posterior margin distinctly oblique at the sides, the 

 disc very minutely punctured when examined under a strong lens ; scutellum broader than long, its apex 

 rounded ; elytra very slightly convex, scarcely visibly punctured ; underside and legs black, with a slight 

 metallic tint ; posterior claw-joint very strongly swollen. 



Hab. Mexico, Hacienda de Bleados, San Luis Potosi (Br. Palmer), Pinos Altos in 

 Chihuahua (Buchan-Hepbum), Jalapa (Edge), Silao, Puebla, La Parada, Tepansacualco 

 (Salle). 



It is possible that this species is but a variety of (E. lug ens, Leconte, from New Mexico ; 

 but this author speaks of pale abdominal segments, and a not sinuate posterior thoracic 

 margin. In (E. modesta the thorax is very distinctly obliquely shaped on each side
