430 PHYTOPHAGA. 



Head with a few distinct punctures near the eyes, black or piceous, the lower part fulvous ; antennae very Bhort, 

 black, the three lower joints generally fulvous and shining, the fourth joint scarcely longer than the third ; 

 thorax with the sides narrowly flattened, the lateral margin straight at the base, rounded towards the 

 apex, the anterior angles with a short tooth, the surface impunctate ; scutellum black ; elytra finely but 

 distinctly punctured, dark blue or blackish aeneous, the first spot transverse, not touching the margins, 

 and widened towards the suture, the two posterior ones near the apex and the apical spot placed at the 

 extremity of the elytron ; the anterior legs and the tibiae more or less dark coloured, the others and the 

 underside fulvous. 



Hab. Mexico, Vera Cruz, Oaxaca (Salle), Jalapa (Hoge) ; Guatemala, Chiacam, 

 Tamahu (Champion). 



This species is principally distinguished by the short antennae ; the design of the 

 elytra is also different from any allied species, there being no spot near the scutellum ; 

 in the variety the elytra have two transverse sinuate bands touching the lateral margin 

 besides the apical spot ; it is probable that specimens occur in which the anterior band 

 is equally divided into two spots. The Guatemalan specimens seem to me to be 

 immature as the elytra are fulvous instead of blue, but the position of the spots and 

 the short antennse are similar. 



56. (Edionychis atroguttata. 



Subdepressed, pale testaceous ; four terminal joints of the antennae black ; thorax impunctate ; elytra very 

 finely punctured, the basal margin, two sutural and five spots on each elytron, black. 



Length 2| lines. 



Head impunctate, deeply transversely grooved between the eyes, the latter large, and the space between them 

 not wider than their diameter ; antennae slender, testaceous, the last four joints black ; thorax narrowly 

 transverse, the sides flattened and rounded, the anterior angles not produced, the surface impunctate ; 

 elytra with the following black markings, a narrow transverse band at the basal margin extending to the 

 shoulders, a spot below the latter and one near the scutellum, a spot at the suture before and a similar 

 one (sometimes wanting) below the middle, a transversely shaped spot at the middle of the disc, and close 

 behind it another one at the lateral margin. 



Hab. Mexico, Presidio, Ventanas (Forrer). 



The narrow black basal band of the elytra seems to be a constant character in this 

 species; in some specimens a more or less distinct costa runs from the shoulder nearly 

 to the apex. 



(E. 6-maculata, lllig., seems to be closely allied ; that species, however, is without a 

 basal black band, and has not so many spots.

Hab. Mexico l 2 , Juquila, Cuernavaca (Salle), Cordova {Edge) ; Guatemala, Capetillo,

The description of this species by Von Harold requires some additional remarks; in 

 the typical form, a specimen of which, named by Sturm himself, I have before me, the 

 thorax has the posterior margin narrowly piceous, and the elytra have two transverse
