specimens befoi-e me and no intermediate forms. *S'. rugicejjs 

 Lef . is described as having the head and thorax confluently rugose- 

 punctate ; in the present species these parts are very closely 

 impressed with round, shallow punctures. 



Syagrus insignitus Jac. (suh Rhembastus). 



This species, described by me in the Ann. k Mag. ISTat. Hist. 

 1898, voL i. p. 353, must find its place in tiyagrus as at present 

 understood ; it is closely allied to S. alluaudi Lef ev., but in that 

 species the head and the clyjDeus are entirely impunctate, the 

 elytra have a deep basal depression and their interstices are 

 rather convex. Typical specimens named by Lef^vre are in my 

 collection, i. insignitus seems, however, a rather variable species, 

 of which the type was probably a unicolorous form. In other 

 specimens which I have received since from the Transvaal the 

 thorax has a central black mark, the elytra have the suture 

 bla,ck at the base and a central spot near the middle of each ; in 

 structural characters I cannot find any difi:erences. 



NODOSTOMA CAMERUNENSE,.sp. n. 



Black or fulvous ; the thorax very strongly and remotely 

 punctured, subangulate at the sides ; elytra deeply punctate- 

 striate anteriorly, the punctures diminishing towards the apex ; 

 legs fulvous. 



Length 2 millim. 



Head remotely but distinctly punctured, the clypeus obsoletely 

 separated ; antennas rather slender, piceous, the basal joints more 

 or less flavous ; thorax scarcely one-half broader than long, the 

 sides angulate below the middle, the surface very strongly and 

 remotely punctured, black ; elytra with a distinct transverse 

 depression below the base, deeply and strongly punctate-striate, 

 the punctures diminishing in size posteriorly, the rows widely 

 separated and the interstices flat, piceous, the base more or less 

 fulvous ; femoia with a minute tooth, the intermediate and 

 posterior tibise emarginate at the apex, claws appendiculate ; 

 presternum broad, only slightly nai'rowed between the coxte, 

 strongly punctured. 



Hah. Cameroons (my collection). 



This is the first species of the genus from Africa and entirely 

 typical. Weise has described another closely allied African genus 

 Aphthonestis, but states that the prosternum is greatly narrowed, 

 which is not the case in the present species. The two specimens 

 before me difi"er greatly in coloration, one being nearly black, 

 stained with fulvous on the elytra, and the other entirely of the 

 latter colour. The angulate thoi-ax and the strong punctuation 

 will assist in the recognition of the species. 



PSEUDIVOXGIUS APICICORNIS, Sp. n. 



Nearly black below, above dark metallic blue ; the basal six 

 joints of the antennse, the base of the tibise, and the tarsi fulvous ;
