band : scutellnm fnlvons, the apex pointed and slightly thickened : elytra distantly 

 and very finely punctured, the suture and the sides black, these two bauds joined by 

 a broad transverse black band near the apex, or if the black is taken for the ground 

 colour, each elytron may be described as having a longitudinal fnlvons stripe from 

 the base to below tlie middle, and a round fnlvons spot at the a])ex ; the femora, 

 the apex of the tibiae, a sj)ot on each side of the breast, the last abdominal segment 

 and the pygidimn black, the rest of the underside .ind legs, fulvous. 



Hab. Gaboon. 



The coloration of this species is different to any which has been described to 

 my knowledge, the central black band of the thorax is, I believe, only jiresent in 

 G. incerta, Leffev., but that sjiecies differs totally in the markings of the elytra and 

 in the entirely black legs. I have only seen two specimens of the present insect, 

 one is contained in this collection and the other in that of my own. 



Gynandrophthalma metallica sp. nov. 



Narrowly elongate, metallic blue, antennae black, the basal joints fnlvons ; 

 thorax impunctate, with an anterior and jinsteriur depression, elytra strongly 

 punctured, the interstices at the sides slightly rugose. 



Length 2i lines. 



Head impunctate at the vertex, the lower jiortion distinctly punctured, with an 

 irregular semicircular depression between the eyes, the anterior margin of the 

 clypeus but slightly concave, the left mandible very large, longitudinally concave 

 above and ending in a long point, antennae very short, the lower three Joints fnlvous, 

 the others black ; thorax strongly transverse, the sides rounded, the posterior 

 margin nearly straight with a very slightly i)roduced median lobe, the surface 

 entirely imimnctate, with a more or less distinct transverse depression at the sides 

 near the anterior and posterior margin ; elytra narrowly elongate, finely and closely 

 punctured, the interstices at the sides very slightly rugose, underside and legs blnish, 

 <dothed with whitish pubescence, legs slender and elongate, the first and second 

 joints of the tarsi elongate, those of the anterior legs especially so. 



Hab. Sierra Leone. 



Somewhat resembling ("optocrphala coendans Fabr., but <if half the size and 

 "width of that species and with elongate tarsi. 



Gynandrophthalma placida Lac. 



Dark blue, closely pubescent, above metallic blue, the antennae black, tlun-ax 

 transverse, nearly impunctate, elytra very strongly and closely punctured. 



Length 2 lines. 



Of elongate, convex ami snbcylindrical shajie, the vertex impunctate, the sjjace 

 between the eyes finely strigose, the clypeus broad, finely punctured, bounded at the 

 sides by an oblique row of punctures, its anterior margin semicircularly concave, 

 labrum and mandibles black, antennae scarcely extending to half the length of 

 the thorax, black, the third joint very thin, obscure piceous, the following joints 

 transverse ; thorax nearly three times broader than long, the sides very slightly 

 rounded, narrowed towards the apex, the angles rather obtuse, the ilisc transversely 

 -convex with an obsolete oblique depression near the posterior angles, the surface 

 iraimnctate with tlie exception of a few fine imnctures near the base, the median 

 lobe of the iiosterior margin sligiitly ]irodnccd and nearly straight ; scutellnm 

 purplish, very broad, its apex slightly thi(!kened and raised, truncate ; elytra sub-
