250 MR. MARTIN JACOBY ON [Feb. 16, 



thorax strongly and ii'regulai'ly punctured; elytra deeply punctate- 

 striate, the interstices longitudinally costate. 



Length 6 millim. 



Head i-emotely but strongly punctured, the clypeus distinctly 

 separated, punctured; eyes large, oblong, i-ather closely approached ; 

 antennae long and slender, black, the lower three joints fulvous ; 

 thorax rather long, distinctly narrowed anteriorly, the lateral 

 margins subangulate near the base, nearly straight anteriorly, 

 the disc strongly and irregularly punctured, with a narrow smooth 

 central space ; scutellum longitudinally depressed ; elytra wider 

 at the base than the thorax, veiy strongly and closely punctate- 

 striate, the punctures transverse in shape, the interstices strongly 

 longitudinally costate, eighth and ninth row of punctures ab- 

 breviated and joined before and below the middle ; underside 

 and legs black ; femora with a small tooth. 



Hah. Benito, Fr. Congo. 



Allied to E. holuhi Jac, but with differently coloured antennae 

 and legs and a strongly punctured thorax. 



EURYDEMUS QUADRIMACULATUS, Sp. n. 



Fulvous ; thorax strongly punctured ; elytra deeply punctate- 

 striate, the interstices longitudinally costate, the fourth intei'space 

 with a black spot before and another below the middle ; femora 

 dentate. 



Length 5| millim. 



Head closely punctured, the epistome well separated, trans- 

 verse, closely punctured ; eyes large, closely approached ; antennae 

 entirely fulvous ; thorax but slightly broader than long, nari-owed 

 anteriorly, the disc strongly and rather closely punctured (in one 

 specimen much more finely so) ; elytra with a distinct basal 

 depression, sculptured as in E. nigriceps, immediately below the 

 depression a small black spot is placed and another below the 

 middle, all the femiora with a small tooth. 



Hah. Zambesi. 



Of this species I possess two apparently female specimens ; it 

 is evidently closely allied to E. raffrayi Lef. in coloiution, as there 

 are likewise two small black elytra! spots in that species ; but 

 Lefevre describes the thorax as " much broader than long," which 

 is certainly not the case in the present insect, and says nothing 

 about the sculpturing of the thoi-ax, nor does he mention any 

 elytral costse. 



EURYDEMUS GENICULATUS, sp. n. (Plate XYII. fig. 11.) 



Above pale fulvous ; thorax closely punctured, with two large 

 black spots ; elytra strongly punctate-striate, the suture and a 

 discoidal stripe, abbreviated posteriorly, black ; knees, base of 

 tibia3 and tarsi, as well as underside black. 



Length 5 millim. 



Head coai-sely punctured, with a central narrow ridge ; clypeus 

 very closely rugose-punctate, intraocular space narroAv ; eyes very
