ON SOME NEW SPECIES OF PHYTOPHAGOUS 

 COLEOPTERA FEOM VARIOUS REGIONS. 



By Martin Jacoby, F.E.S. 

 Gynandkophthalma apicalis, n. sp. 



Elongate, fulvous ; the antennae (the basal joints excepted) black; thorax 

 impunctate ; elytra extremely finely punctured in double rows, violaceous 

 blue, their apex fulvous. Length, 2 — 3^ lines. 



Head with a shallow depression between the eyes, this space finely punc- 

 tured ; eyes triangularly notched, the anterior margin of the epistome very 

 deeply emarginate-concave, the sides also emarginate to a less extent ; 

 antennae not quite extending to the base of the thorax, black, the lower four 

 joints fulvous ; thorax transverse, the sides slightly rounded, the posterior 

 margin broadly but slightly lobed at the middle, the surface impmictate or 

 with a few minute punctures, obsoletely transversely depressed in front of 

 the scutellum ; the latter fulvous, its apex rounded ; elytra dark violaceous 

 blue, shining, with double rows of very fine punctures, the apex impunctate, 

 fulvous ; underside and legs entirely of that colour. 



Hah. South Africa, Ehobomp, Sierra Leone. (Coll. Jacoby.) 

 This species, of which the female insect is nearly twice the 



size of the male, seems to be closely allied to G. terminata, Lac, 



but differs in the entirely fulvous underside, and in the colour of 



the elytra and their fine punctuation. 



A specimen of this and the following species were kindly given 



to me by M. Deyrolle. 



Gynandkophthalma seminigba, n. sp. 



Black ; the thorax strongly but sparingly punctured ; elytra deeply and 

 closely punctured, the anterior half fulvous ; a spot near the middle, and the 

 posterior portion, black. Length, 3 lines. 



Head finely rugosely punctured between the eyes, the vertex smooth ; 

 antennae extending to the base of the thorax, black, the basal three joints 

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

 slightly rounded, with a narrow margin, the surface remotely and strongly 

 punctured, black, shining ; scutellum black, with a few punctures ; elytra 

 subcylindrical, slightly constricted at the sides near the middle, closely and 

 strongly punctured, the punctures arranged in ill-defined strias near the apex, 

 the posterior portion black, its anterior edge deeply concave, the anterior 

 portion fulvous and including a subquadrate black spot near the suture 

 before the middle ; imderside and legs black, clothed with greyish pu- 

 bescence. 



Hah. Ehobomp, Sierra Leone. (Coll. Jacoby.) 

 Colasposoma thibettanum, n. sp. 



Metallic violaceous blue ; the antennae and tarsi black ; the head and 

 thorax closely and strongly punctured ; elytra bright metallic cupreous, the 

 lateral margin violaceous, the surface closely semipunctate- striate ; the femora 

 with a small tooth. Length, 5 lines. 



Of robust and subquadrate shape ; the head closely and strongly punc- 

 tured, the interstices at the sides longitudinally strigose, the middle with a
