PHYTOPHAGA. 



M. Lefevre in the Munich * Entomologische Mittheilungen.' Whether these latter 

 species belong, strictly speaking, to Chapuis's genus, seems somewhat doubtful to me, 

 as none of M. Lefevre's species are described as being pubescent on any part. In the 

 species described here the principal characters are present ; the general outlines of the 

 insects, however, are at variance with the type ; and they may possibly form another 

 genus. The species described up till now have been from South America. 



2. Agbalus quadriplagiatus. 



Oblong, slightly convex, black ; head and thorax finely pubescent ; elytra strongly punctate-striate, interstices 

 snbrugose, black, an elongate patch, covering the shoulder and the base, as well as a round small spot at 

 the apex light red. 



Length 3 lines. 



Head closely and distinctly punctured, sides of the vertex substrigose ; clypeus broad, limited in front by a 

 shallow depression and two elevated smooth spaces ; labrum square-shaped, fulvous, piceous at the middle ; 

 left mandible strongly developed ; antennae scarcely half the length of the body, robust, black, second and 

 third joint fulvous, apical joints much thickened, pubescent ; thorax transverse, rather convex, sides much 

 rounded, anterior angles produced into an acute tooth, surface very closely punctured, the sides covered 

 with thin but distinct pubescence ; scutellum as broad as long, punctured at the middle ; elytra about 

 three times as long as the thorax, but slightly convex, covered throughout with deep punctures, arranged 

 partly in regular lines, with the interstices transversely rugose ; a large bright red spot extends across the 

 base and shoulder to nearly the middle of the elytra and to the lateral margin, its inner margin being 

 very concave, another small elongate spot is situated at the extreme apex ; underside and legs black ; 

 anterior tibiae armed at their extreme apex with a short acute tooth. 



Hdb. Mexico, Oaxaca (Salle). 



2. Agbalus mexicanus. 



Oblong, greenish black ; head and thorax metallic green, finely pubescent ; elytra fulvous, semi-punctate-striate, 



and transversely rugose ; legs fulvous, tarsi black. 

 Length 2| lines. 



Hah. Mexico, Oaxaca (Salle). 



The present species so much resembles the preceding one in every respect, except in 

 its colour and size, that a detailed description of it is unnecessary. Whether it is but 

 a variety of A. quadriplagiatus I am not able to say, as of each I have unfortunately 

 but a single specimen for comparison. 



EUPHRYTUS. 



Elongate, convex, parallel; eyes sinuate, large; last joint of palpi ovate, its apex subtruncate; antennae 

 robust, the basal joints short, the terminal ones thickened ; thorax transversely convex, its sides rounded 

 and entire; elytra irregularly punctured; legs slender, the posterior femora incrassate and sometimes 

 toothed ; first tarsal joint as long as the two following united ; claws appendiculate ; prosternum greatly 

 narrowed between the thighs, its base truncate ; anterior thoracic episternum concave. 



I propose this genus for the reception of a few Mexican species having the general 

 appearance of certain members of the genera Chalcophana and Coytiera. From 

 the last of these the thickened antennae and dilated femora separate it, while it is
