54 Mr. F. P. Pascoe on some new or little-known 



many among the Heteromera ; in its habit it resembles Scraptia ; but 

 as the more important characters are those of Melandryidae, and that 

 family is also one which contains several anomalous forms, it seems 

 less objectionable to place it in that group than in any other. 



Biophida unicolor. (PL III. fig. 4.) 

 B. fulvo-testacea, pube pallidiori vestita ; prothorace bifoveolato ; oculis 



fere concoloribus. 

 Hab. Natal. 



Entirely of a light-brownish testaceous colour, rather closely covered 

 with short stiffish paler hairs ; a large fovea on each side of the pro- 

 thorax near the posterior angle ; scutellum transverse, rounded behind ; 

 eyes a little darker. Length 4 lines. 



Ischalia [Pedilidae ?]. 



Head small, contracted behind, and narrowed anteriorly below the eyes. 

 Antennae shorter than the body, linear, 11-jointed; second joint smallest, 

 the rest subequal. Eyes reniform. Epistome and labruni large, covering 

 the mandibles. Maxillary palpi robust, the last joint securiform ; labial 

 much shorter, terminating in a broad triangular joint. Maxillae short, 

 obtuse. Prothorax narrowed anteriorly, irregular above, its posterior 

 angles produced, the epipleurae confounded with the pronotum. Elytra 

 broader than the prothorax, subparallel, bent at the side, and concave 

 on the disc, the epipleural plait narrow. Legs moderate, anterior 

 acetabula open behind; all the coxae approximate, the anterior and 

 intermediate conical; tibiae unarmed; tarsi short, first joint longer 

 than the rest together, the penultimate bilobed ; claws simple. 



I refer this genus doubtfully to Pcdilidae, notwithstanding that it 

 agrees in two characters which M. Lacordaire considers of high im- 

 portance, viz. the anterior acetabula largely open behind, and the 

 complete contiguity of the posterior coxse. The family, however, as 

 it stands at present, is not a satisfactory one, and its learned pro- 

 poser will probably see reasons for modifying it eventually. 



Ischalia indigacea. (PI. III. fig. 6.) 

 J. cyaneo-violacea; an tennis pedibusque nigris, illis articulis tribus ultimis 



albis. 

 Hab. Borneo. 



Deep violet-blue ; head and prothorax very minutely punctured 



(scarcely visible under a strong lens), the latter more or less irregular ; 



scutellum small, triangular ; elytra coarsely punctured, rich violet-blue ; 



antennae black, with the last three joints white ; legs black ; body beneath 



black, with a slight bluish tinge on the breast. Length 3-4 lines. 



The irregularity of the surface of the prothorax varies ; in extreme
