Head with a few minute punctures, deeply triangularly depressed 

 Ijetween the eyes, black as well as the labrum, antennas black, the 

 l(jwer three joints more or less fulvous Ijelow (the terminal three 

 joints wanting) ; thorax strongly transverse, more than twice as broad 

 as long, the sides obliquely narrowed anteriorly, subangulate near 

 the base, with a distinct reflexed margin, the anterior angles produced 

 outwards, the surface with a few very minute punctures, fulvous, 

 scutellum black ; elytra irregularly and very closely punctured, with- 

 out basal depression, fulvous, the shoulders with a black spot, ending 

 in two elongate stripes, which run parallel to below the middle, the

 deeply concave at the suture and including a small fulvous spot of 

 the ground colour, elytral epipleuras fulvous anteriorly, black below

Hob. Upper Amazons. 



I only know a single female specimen of this rather 

 aberrantly formed and marked species, which probably 

 varies a good deal in the design of the elytra ; these differ 

 from those of any other species of the genus, and the 

 angulation of the thorax and its greatly transverse shape 

 is likewise strange to the majority of its aUies, but not 

 important enough to separate the species generically; it 

 was on a somewhat similarly shaped species — G. histrio, 

 Baly — that Baly founded his genus Gychrea, which cannot 

 rightly be separated from Ghalcoj^ihaMt. 



PSEUDOCOLASPINiE. 



All the genera inchided in tliis section are Eastern, the 

 only exception is Splixroins, which inhabits the southern 

 and central portion of America. The species of this genus 

 are all pubescent and of small size ; not more than 6 or 8 

 species are at present known, to which I add anotlier one 

 here. 



Bphcvropisfrvhstoo'feri, sp. n. 



Obscure aeneous, clothed with silvery puln'scence, the basal joints 

 of the antenufu and ihe tiliiie and tarsi, more or less, fulvous, thorax 

 closely and strongly punctured, elytra more finely but as closely 

 punctured, the shoulders raised in shape of a short ridge.
