COLASPOIDES. 187 



The original description gives the head as deeply punctured, which is a mistake ; it 

 ought to be distinctly hut finely punctate. The species is of a uniform dark violaceous 

 blue colour ; but the labrum and the legs, especially the anterior ones, are more or less 

 distinctly metallic green ; the thorax is also very finely punctured, sometimes almost 

 impunctate, at the disk ; and the elytra, although very closely, are also rather finely 

 punctate. The species (of which specimens showing no difference have been lately 

 received from Chiriqui) seems very closely allied to C. viridicomis, Lef., from Colombia, 

 but differs in the fine punctuation of the head and the uniformly fulvous basal joints of 

 the antennae. 



4. Colaspoides quadriplagiatus. 



Ovate, moderately convex, below black ; antennae and legs testaceous ; thorax metallic green or aeneous, closely 

 punctured ; elytra violaceous, a square-shaped spot at the shoulder and another at the apex of each 

 elytron fulvous. 



Length 1-1 1 line. 



Head metallic green, deeply longitudinally grooved in the centre, strongly but not very closely punctured ; 

 clypeus triangular; antennae entirely testaceous, about half the length of the body ; thorax about three 

 times as broad as long, the anterior margin distinctly sinuate behind the eyes and produced at the middle, 

 posterior margin distinctly produced or widened ; surface closely and rather strongly punctured ; scutellum 

 broadly ovate, minutely punctured ; elytra rather regularly and closely punctate-striate at their anterior 

 portion, the striae towards the apex finer and much wider apart, dark violaceous blue, each elytron with 

 a rather large generally square-shaped spot at the shoulder, and another rounded one near the apex, 

 fulvous : these spots do not extend to the sutural margin. Legs and tarsi testaceous. 



Hab. Guatemala, San Geronimo, El Jicaro {Champion). 



This little species, of which but four specimens were obtained, resembles somewhat 

 in size and markings C. dorsata, Baly, from which it differs sufficiently in the arrange- 

 ment of the elytral spots and the colour of the thorax. 



5. Colaspoides marginatus. 



Ovate, black ; antennae and legs light fulvous ; head and thorax metallic green, finely punctured ; elytra more 

 strongly punctate-striate, black, the lateral margins metallic green. 



Length 1 line. 



Head with a distinct central longitudinal groove, remotely but distinctly punctured ; clypeus triangular, sepa- 

 rated from the face by finely impressed lateral grooves, strongly punctured ; antennae entirely fulvous, the 

 last five joints distinctly thicker than the rest ; thorax narrowly transverse, the sides moderately deflexed, 

 lateral margins rounded and narrowed towards the apex, surface rather remotely and finely punctured ; 

 scutellum ovate, impunctate, metallic green ; elytra slightly narrowed towards the apex, much more 

 strongly punctured than the thorax, and the punctuation arranged in rather regular and close lines ; the 

 interstices near the lateral margins slightly costate; surface black, the extreme base and the lateral 

 margin narrowly metallic green. Legs and tarsi fulvous ; anterior thoracic episternum convex at the 

 middle. 



Hab. Guatemala, San Geronimo (Champion).
