ALETES. 147 



fovea; labrum and palpi fulvous; antennae half the length of the body, robust, the joints slightly 

 thickened at their apex and compressed, fulvous, last five joints piceous ; thorax transverse, moderately 

 convex, anterior margin straight, posterior one rounded and produced at the middle, sides rounded, 

 obsoletely three-sinuate, surface metallic bluish green, finely and rather closely punctured at the disk, a 

 little more strongly at the sides ; scutellum ovate ; elytra slightly depressed below the base, punctate- 

 striate near the suture, the interstices at the sides strongly transversely rugulose, the apex subcostate ; 

 underside black, last abdominal segment fulvous ; legs of the same colour, robust ; tibise dilated at the 

 apex, anterior first tarsal joint dilated, as well as the posterior one. 



Hab. Mexico, Jalapa {Edge). 



2. Aletes guatemalensis. 



Subelongate, greenish black below; antennae, legs, and abdomen fulvous; above metallic dark blue; thorax 

 strongly punctured; elytra regularly subgeminate punctate-striate, transversely rugose at the sides. 



Length 2| lines. 



Head with a central longitudinal groove, closely covered with oblong punctures, more crowded at the sides ; 

 clypeus strongly punctate, limited in front by two smooth raised spaces; labrum and palpi fulvous, jaws 

 black; antennas robust, entirely fulvous; thorax less transverse than in A. mexicanus, its sides very 

 obsoletely triangulate ; surface very irregularly impressed with smaller and larger punctures, the latter 

 predominating at the sides and the base ; elytra very regularly and rather strongly subgeminate punctate- 

 striate at the sutural half, transversely rugose and subfoveolate punctate at the sides, the interstices at the 

 apex distinctly costate, the latter itself rather pointed ; legs fulvous. 



Hab. Guatemala, Capetillo (Champion). 



Although only a single specimen of this species was obtained at Capetillo, I 

 believe it to be distinct from A. mexicanus, as well as from A. variabilis, on account of 

 the much more regular punctuation of the elytra, which in the latter species are 

 distinctly geminate punctate-striate and deeply depressed below the base, this depres- 

 sion being only slightly indicated in the present insect; the thorax is also much more 

 strongly punctured ; and the insect is of smaller size. 



3. Aletes variabilis. (Tab. IX. fig. l.) 



Subelongate, fulvous below; above metallic green or purplish; head strigose-punctate ; thorax minutely punc- 

 tured, its sides bisinuate; elytra subgeminate punctate-striate, sides transversely rugose. 

 2 . Elytra with a row of tubercles at the sides. 

 Var. a. Antennas and legs entirely fulvous. 

 Var. b. Underside, legs, and antennae black. 



Length 3-3| lines. . L L , 3 , 



Head longitudinally grooved in the centre, closely and strongly strigose-punctate ; clypeus deeply concave- 

 emarginate, its sides angulate ; labrum fulvous; antennae one third the length of the body, robust, either 

 entirely fulvous or with the terminal joints black; thorax not more than twice as broad as long, sides 

 rounded and- narrowly margined,' more or less distinctly bisinuate, surface moderately closely and very 

 finely punctured; scutellum subovate, metallic green or obscure fulvous; elytra elongate, pointed towards 

 the apex, deeply transversely depressed below the base, strongly geminate punctate-striate near the suture, 

 rest of the surface irregularly punctured and near the sides transversely rugose. 

 P . Elytra generally less strongly punctured on the disk, with one or two rows of tubercles of irregular shape 

 from the shoulder to more than two thirds the length of the elytra. 



Hab. Guatemala, Purula, Sabo, Sinanja (Champion). 



Of this species about thirty specimens were obtained, principally from Purula ; they
