1897.] PHTTOPSAGOtrS COLBOPTEH.A. OF AFRICA. 251 



with three longitudinal black bands; this design is peculiar to 

 many species and subject to great variation ; all the tibiae in this 

 variety are likewise fulvous, and the locality is a different one, the 

 elytral punctuation also differs : in spite of all this, the differences 

 are so entirely those of degree, and the elytral pattern and 

 direction of the bands are so similar, that I believe to be right in 

 looking upon this form as a local vai'iety only, more especially as the 

 wide distribution of African insects is well known. 



Peploptbka lateralis, n. sp. 



Black ; thorax impunctate, rufous with a central black spot ; 

 elytra finely and semiregularly punctured, flavous, a sutural and 

 sublateral stripe, as well as the lateral margins, black ; tibiae 

 fulvous. 



Length 3| lines. 



Head and antennae as in the preceding species ; thorax rufous, 

 very narrowly edged with black, the sides slightly rounded, straight 

 at the base, the surface entirely impunctate, the space in front of 

 the seutellum depressed, with a few punctures, the middle with a 

 narrow black stripe not extending to the apex ; seutellum black, 

 small ; elytra flavous, with rows of small punctures rather regu- 

 larly placed, which nearly disappear near the apex ; the suture to 

 the whole extent narrowly black, forming a baud which is slightly 

 widened near the apex and angulate below the base, another 

 narrow and regular band, slightly narrowed at its middle, extends 

 from the shoulder nearly to the apex, the lateral margin from the 

 middle downwards is likewise narrowly edged with black ; under- 

 side clothed with silvery pubescence ; tibiae fulvous ; tarsi very 

 broad. 



Hah. Tabora, Ounyamyembe. 



In this species the lateral black stripe of the elytra is placed not 

 at, but before the margin, leaving a space as broad as the band itself 

 between the latter and the lateral edge ; in this resjiect the species 

 differs from any of its allies. A single specimen is contained in 

 my collection. 



Laohw^a marshalli, n. sp. (Plate XVII. fig. 4.) 



Black; the head and thorax finely pubescent, the anterior 

 margin and the sides of the latter flavous ; elytra very finely 

 punctured, fulvous, each with four small black spots placed trans- 

 versely (2. 2). 



Length 4 lines. 



Head closely rugose and sparingly pubescent, the vertex fiuely 

 punctured, the front with a longitudinal central groove, anterior 

 margin of the clypeus triangularly emarginate, mandibles large ; 

 antennae extending to the base of the thorax, black, the apex of 

 the first, and the second and the third joint entirely, fulvous, 

 third joint very short, fourth triangularly elongate, the following 

 joints very strongly transversely widened ; thorax more than twice 

 as broad as long, the sides strongly rounded, as well as the posterior
