242 ME. M. JACOBY ON PHXPOPHAGOUS COLEOPTEEA [Mar. 6, 



Length 8 millim. 



Head very finely and sparingly punctured, flavous ; autennae 

 black, the lower tour joints flavous, terminal joints strongly di- 

 lated ; thorax rather more than twice as broad as long, strongly 

 narrowed in front, the lateral margins very feebly, the posterior 

 one very strongly rounded, the disc transversely convex, extremely 

 minutely and rather sparingly punctured, the punctures more 

 distinct at the sides and more closely placed ; scutellum flavous, 

 impunctate ; elytra not wider at the base than the thorax, but 

 slightly widened posteriorly, very closely and much more strongly 

 punctured than the thorax, the punctures evenly distributed and 

 the interstices aciculate, black, shining, the extreme apex flavous ; 

 below black, the prosternum, part of the metasternum, and the last 

 abdominal segment flavous. 



Hah. Cameroons. 



Distinct in coloration from any of its allies. 



Ceralces ornata Baly ; Ceralces spilota Baly ; Ceralces walleri 

 Baly. — These three species, of which Mr. Gahan and I have 

 examined the types in the British Museum, have bifid claws and 

 closed anterior cavities, and must find their places in Lygaria. L. 

 mutdbilis Kolbe is identical with L. spilota and his variety bvmacu- 

 lata with L. ornata Baly ; Lygaria rohusta Weise is probably 

 identical with Baly's L. walleri. 



Plagiodera congoensis, sp. n. 



Fulvous below, the antennae and the legs black, above flavous ; 

 thorax with three longitudinal stripes and a spot at the sides 

 piceous, closely punctured ; elytra closely and strongly punctured, 

 a transverse angular and interrupted band before and another one 

 below the middle, as well as a spot near the apex, blackish. 



Length 7 millim. 



Evenly rounded and moderately convex, the head strongly 

 punctured, fulvous at the vertex, with a flavous subquadrate spot 

 between the eyes, the latter distinctly notched, the clypeus raised 

 into a transverse ridge anteriorly: antennas extending to the 

 base of the thorax, black, the lower four joints more or less 

 flavous below, terminal joints strongly transversely widened ; 

 thorax more than twice as broad as long, the anterior and posterior 

 margins parallel, strongly curved, the sides nearly straight, narrowed 

 towards the apex, the angles not produced but distinct, the surface 

 irregularly and rather finely punctured, the punctures of different 

 sizes, more closely placed and larger at the sides than on the disc, 

 the ground-colour flavous, a mediall) strongly dilated or diamond 

 shaped band at the middle, from base to apex, another narrower 

 band at the sides, interrupted anteriorly, and a small spot near the 

 anterior angles, piceous ; scutellum broad, black ; elytra evenly, 

 strongly, and closely punctured, flavous, each elytron with an 

 oblique stripe from the middle of the base towards the suture, of 

 greatly angulate shape and connected with a spot at the sides, 

 a somewhat similar band, strong! v annulate or dentafp. below the
