1897.] PHTTOPHAGOTJS COLEOPTEKA OF AFRICA. 243 



Length 2| lines. 



Head impunctate at the vertex, the space round the eyes finely 

 punctured and pubescent, with a short central groove ; antennas 

 very short and robust, black, the basal two joints fulvous ; thorax 

 subcyHndrical, but slightly constricted at the base ; the sulcus 

 indistinct and placed close to the base, the disc with two rows of 

 rather deep punctures at the middle and a few others near the 

 anterior angles ; elytra with deep round punctures, placed in 

 closely approached rows, the punctuation getting finer towards 

 the apex, the interstices sparingly impressed with minute pvnic- 

 tures, convex near the apex, there are some slight transverse wrinkles 

 to be seen below the base ; underside and the femora fulvous, 

 clothed with extremely short yellow pubescence, tibiae and tarsi 

 piceous or black. 



Hah. Madagascar, Diego-Suarez (C. Alluaud). 



Smaller than G. livida, Dahlm. ; the thorax more cylindrical and 

 with two rows of punctures only ; the antennsB also differently 

 coloured. 



Cbioceeis madagascabiensis, n. sp. 



Dark fulvous ; antennae short, the last four joints black ; thorax 

 flat, strongly and closely punctured ; elytra finely punctate-striate, 

 the interstices sparingly and finely punctured. 



Length 3 lines. 



Head deeply constricted at the base, with a short central and 

 deep lateral grooves ; eyes deeply notched ; clypeus finely punc- 

 tured ; palpi filiform ; antennae extending to the base of the 

 thorax only, the second joint moniliform, third and fourth short, 

 equal, the following joints triangularly widened, the terminal ones 

 strongly transverse, the lower seven joints fulvous, the others 

 black ; thorax subquadrate, slightly longer than broad, but mode- 

 rately constricted at the middle, the anterior angles rounded, the 

 surface rather flattened, strongly, irregularly, and closely punctured, 

 the space near the base nearly impunctate, with a very feeble 

 transverse sulcation ; scutellum narrowly elongate ; elytra not 

 depressed below the base, nor raised near the scutellum, with very 

 regular rows of punctures, which are larger anteriorly on the 

 inner disc, the interstices fiat, with a single row of fine punctures 

 which are more or less interrupted, lateral margin strongly thick- 

 ened ; underside nearly smooth and impunctate ; tarsi blackish. 



Hab. Madagascar, Diego-Suarez (Alluaud). 



Closely allied to C, antennalis, Lac, also from Madagascar ; but 

 smaller, the last four, not five joints of the antennae black, the 

 thorax much more strongly and closely punctured, and the elytral 

 interstices likewise finely punctulate. C. dimidiaticornis, Lac, is 

 described as having the antennae one-third the length of the body, 

 the interstices of the el)'tra finely alutaceous and convex posteriorly, 

 and the apex of the tibiae black as well as the tarsi. M. Alluaud 

 has sent me three specimens of the present species which show no 

 differences in any way.
