COLASPIS. 145 



21. Colaspis impressa. (Tab. vm. fig. 23.) 



Colaspis impressa, Lefev. Ann. Soc. Ent. France, 1876, p. 139 1 . 

 Hab. Mexico, Cuernavaca {Salle) ; Guatemala. — Brazil, Rio Janeiro 1 . 



Three specimens from M. Salle's collection agree sufficiently with the author's 

 description to enable me to place them with that species ; but an examination of the 

 type is necessary to be certain on this point. The species before me has the thorax 

 crowded with oblong punctures; the antennae are nearly black (in which respect they 

 do not agree with the description) ; the elytra are finely punctate-striate, depressed 

 below the base, and of a dark metallic-blue colour. The crowded punctuation of the 

 thorax will separate this species from C. laticollis. 



22. Colapsis jansoni. 



Oblong-ovate, black ; above metallic green ; thorax very finely punctured ; elytra depressed below the base, 

 geminate punctate-striate near the suture, strongly and irregularly punctured at the sides. 



Length 2 lines. 



Head with a more or less distinct purplish tint, rather strongly but not very closely punctured, the space 

 between the eyes impressed by a small fovea ; clypeus finely punctured, not separated from the face ; 

 labrum obscure fulvous or piceous ; antennae black, the basal joints obscurely fulvous at the apex ; thorax 

 transverse, the sides angulate at the middle, the anterior angles produced into a distinct tooth ; surface 

 very finely and closely punctured; elytra distinctly depressed below the base, much more strongly 

 puncttired than tbe thorax, the punctures arranged near the suture in double lines at the base, but singly 

 towards the apex, sides much more strongly and irregularly punctured, the interstices obsoletely trans- 

 versely rugose ; entire underside and legs black. 



Hab. Nicaragua, Chontales (Janson, Belt). 



The small size, black underside and legs, in connexion with the fine punctuation of 

 the thorax, will distinguish the present species, of which but two specimens were 

 obtained by Janson and one by Belt. 



23. Colaspis godmani. 



Oblong, subovate, convex, fulvous ; legs and base of the antennae flavous ; above metallic green ; a basal round 

 spot and a sutural and lateral longitudinal band, from below the base to the apex, obscure cupreous. 



Length 1J line. 



Head strongly but not very closely punctured, deeply transversely grooved between the eyes ; spaces in front 

 of the antennae raised, smooth ; labrum and palpi fulvous ; antennae piceous, the first five or six joints 

 light fulvous; thorax distinctly angulate at the middle; surface strongly and closely punctate; elytra 

 deeply transversely depressed below the base, subgeminate punctate-striate near the suture, deeply punc- 

 tured and transversely rugose near the sides, the latter from below the base to the apex narrowly 

 cupreous, a broader band of the same colour running parallel with the suture, and a round cupreous spot 

 occupying the base of each elytron ; underside fulvous ; legs flavous. 



Hab. British Honduras, river Sarstoon, river Hondo (Blancaneaux) ; Guatemala, 

 Zapote, Cahabon, San Juan, Cubilguitz (Champion) ; Nicaragua, Chontales (Janson). 



This pretty little species seems to be very closely allied to C. jpulchella, Lefev., from 

 which it differs in the fulvous underside, the uniform flavous legs and tarsi, and in the 

 biol. centr.-amer., Coleopt., Vol. VI. Pt. 1, February 1882. u
