32 Mr. M. Jacoby's Descriptions of New Genera and 



Lwperus tliomsoni, sp. n. 



Fulvous, the intermediate joints of the antennte black, thorax 

 obsoletely sulcate, impunctate, elytra very finely punctured, elongate. 

 Length 5| millim. 



Of elongate, parallel shape, entirely fulvous, the head impunctate, 

 eyes very large, frontal elevations transverse, strongly marked, eyes 

 large, antennaa extending beyond the middle of the elytra fulvous, 

 the fourth to the eighth joint black, basal joint elongate and rather 

 slender, second one about one-third shorter than the third joint, 

 fourth and following joints elongate, nearly equal ; thorax trans- 

 versely subquadrate, the lateral margins feebly rounded and slightly 

 constricted at the base, the surface with a broad transverse depression, 

 more deeply marked at the sides than at the middle, entirely 

 impunctate, scutellum smooth, triangular ; elytra wider at the base 

 than the thorax, the surface very finely and closely punctured, their 

 epipleurre rather br(jad at the base, gradually greatly narrowed 

 towards the apex, legs slender, the metatarsus of the posterior ones 

 very elongate ; all the tibiiTO mucronate, the anterior coxal cavities 

 open. 



Hah. Sierra Leone. 



Tiie colour of the anteoDse and the entirely impunctate 

 and sulcate thorax characterise this species, which has also 

 the metatarsus more than usually elongate, resembling the 

 genus Monolepta, from which the open anterior coxal 

 cavities and prolonged elytra epij)leura3 separate it. 



Luperus semifoveolatus, sp. n. 



Below black, above testaceous, head dark fulvous, antennro long, 

 fulvous, thorax subquadrate, narrowed at base, obsoletely bifoveolate, 

 impunctate, elytra not perceptibly punctured. Length 3h millim. 



Elongate, the head impunctate, dark fulvous, frontal elevations 

 broadly trigonate, clypeus rather wide and broad between the 

 antenniT3, eyes large, labrum at the apex and the palpi piceous, 

 antennpc slender, the second joint one-half shorter than the third, the 

 fourth and fijUowing joints elongate and cylindrical, the apical joint 

 extending to about half the length of the elytra ; thorax subquadrate, 

 distinctly constricted at the base, the lateral margins rounded before 

 the middle, the disc with an obsolete transverse depression, sub- 

 foveolate at the sides, impunctate, testaceoits ; elytra wider at the 

 base than the thorax, extremely finely wrinkled, nearly imjDunctate, 

 some extremely fine pu.nctures visible only near the base when seen 

 under a powerful lens, legs slender, testaceous, the tibiae finely
