EHABDOPHOETJS. 149 



Head rather closely covered with larger and smaller punctures ; clypeus indistinctly separated from the face, 

 its apes deeply concave-emarginate j antennae two thirds the length of the body, fulvous, the three or four 

 last joints piceous ; thorax nearly as wide as the elytra, very moderately deflexed anteriorly, the anterior 

 angles acute, its sides rounded and narrowly margined, surface more or less distinctly but remotely punc- 

 tured at the disk, more closely at the sides, entirely fulvous ; scutellum of the same colour ; elytra metallic 

 green, their apex rather pointed and narrowed, surface with three double rows of punctures, which unite, 

 however, into single lines towards the apex, near the suture, the rest of the disk deeply and closely 

 punctate-striate, the interstices towards the sides closely and strongly transversely wrinkled and rugose ; 

 underside and legs entirely fulvous. 



Edb. Mexico, Oaxaca (Boucard, coll. Salle) ; Guatemala, near the city (Salvin). 



The fulvous colour of the legs, head, and thorax, and the metallic-green elytra, 

 make this species recognizable at first sight; the punctuation of the thorax seems 

 subject to variation, being much finer in some specimens than in others ; and the head 

 is sometimes of a distinct metallic-green colour, this latter being entirely absent in 

 others. The species does not seem to be an abundant one, as only five specimens are 

 before me from Mexico and Guatemala. One from the latter country is figured. 



3. Rhabdophorus perplexus. 



Oblong, light fulvous ; seventh and two last joints of the antennae black ; above fulvous with a metallic-green 

 gloss ; thorax closely and finely punctured ; elytra geminate punctate-striate, the interstices co state. 



Length 3 lines. 



Head with a few deep punctures, impressed between the eyes ; clypeus separated from the face by two fine 

 lateral grooves, punctured, its apex deeply concave-emarginate ; terminal joint of palpi piceous ; elytra 

 two thirds the length of the body ; thorax distinctly narrowed in front, transverse, its sides rounded or 

 obsoletely sinuate, its surface irregularly and closely covered with larger and smaller punctures ; scutellum 

 subpentagonal ; elytra very strongly geminate punctate-striate anteriorly and near the suture, simply 

 punctate-striate towards the apex, rest of the disk more irregularly punctured and transversely rugose; 

 the interstices at the apex strongly costate, those of the other parts subcostate ; underside and legs light 

 fulvous ; prosternum broad. 



Hob. Guatemala, Purula {Champion). 



Of this species about fifty specimens were sent by Mr. Champion. The shape of the 

 thorax is much more that of a true Colaspis than it is generally in the genus before 

 us ; but the broad prosternum shows its affinity to Rhabdophorus. In colour the species 

 much resembles Colaspis submetallica ; but the absence of the teeth at the sides of the 

 thorax in the present insect will at once distinguish it. 



4. Rhabdophorus jansoni. 



Oblong-ovate, piceous below ; above metallic dark green ; thorax finely and remotely punctured ; elytra very 

 strongly punctate-striate, the apex longitudinally costate, the sides subrugose. 



Length 3-3| lines. . . 



Head closely punctured ; clypeus rugose-punctate ; antennas fulvous, the seventh joint piceous, the rest wanting ; 

 thorax transverse, the sides evenly rounded and narrowed towards the apex ; surface finely and remotely 

 punctured on the disk, more closely towards the side ; scutellum distinctly broader than long ; elytra of a 

 dark metallic green colour, very obsoletely depressed below the base, the punctures arranged in rather
