254 MR. MARTIN JACOBY OX [Feb. 16, 



thorax finely and moderately punctured ; elytra distantly punc- 

 tate-striate. 



Length 2-2j millini. 



Ovate, very convex, pointed posteriorly ; the head finely and 

 rather obscurely punctured, with a short central obsolete groove ; 

 labrum fulvous ; antennje widely separated at the base, long and 

 slender, the lower six joints fulvous, the rest black, second joint 

 nearly as long as the third, but thicker ; thorax transverse, of 

 nearly equal width, the lateral mai'gins straight, the surface finely, 

 remotely, and irregularly punctured, the sides nearly impunctate 

 near the margins ; scutellum blackish, trigonate ; elytra Avidened 

 at the middle, very convex, pointed at the apex, finely punctured 

 in distantly placed rows, with other punctures here and there on 

 the interstices ; femora thickened, unarmed, dark blue, the apex 

 fulvous ; anterior tibife entirely fulvous, the others of this colour 

 at the base only, the apex obscure teneous ; tarsi fulvous. 



Hah. Upper Tongaat, Katal (C Barker). 



This is the third known species of the genus (Proc. Zool. Soc. 

 1897, p. 546, 1898, p. 228). It difi'ers from F. natalensis Jac. in 

 the colour of the antennse and legs, and in the much more finely 

 punctured thorax and elytra ; from P. ceneios Jac. in having the 

 basal six, instead of four, joints of the antennae fulvous, and in the 

 much more slender and elongate legs. In regard to P. natalensis 

 in which the elytra have two short humeral costas, this character 

 is only peculiar to the female sex ; of the insect described here 

 Mr. Barker has sent two specimens, evidently also females, in 

 which the first joint of the tarsi is rather elongate. All the 

 species of the genus are of somewhat spider-like appearance and 

 resemble the genus Pallena, which, however, belongs to the first 

 division of the Eumolpidte, with a concave, not convex, anterior 

 thoracic episternum. 



LiNISCUS IXTERSTITIALIS, Sp. n. 



Piceous witli reneous gloss ; antenna; and legs dark fulvous ; 

 thoi'ax very closely punctui-ed ; elytra, obscure aeneous, regularly 

 punctate-striate, the interstices with a fine row of punctui'es. 



Length 3 millim. 



Nai-rowly subcylindrical, the head very closely and strongly 

 punctured, the clypeus feebly separated from the face, eyes oblong, 

 slightly sinuate ; antennae dark fulvoiis, the terminal five joints 

 strongly widened, third joint one-half longer than the second, 

 basal joint subquadrately widened; thorax scarcely one -half 

 broader than long, the sides rounded, rather strongly widened at 

 the middle, the disc punctured like the head ; elytra of slightly 

 paler colour than the thoi'ax, with more or less aeneous gloss, 

 rather strongly punctate-sti'iate anteiiorly, the intei'stices with a 

 single row of very fine punctures ; legs robust, obscure piceous or 

 dark fulvous ; femora unarmed ; claws very finely bifid at the 

 base only. 



Hah. Beira, E. Africa [A. SJieppard). 



Beadily distinguished from the other species of this genus by 

 the punctured elyti'al interstices.
