vitta, and a submarginal vitta on each elytron reaching from the 

 middle to the apex, where it joins the sutural vitta, cinnamon- 

 coloured ; a small punctiform spot at the extreme base, two spots 

 in front of the middle and two behind the middle of each elytron, 

 snow-white ; the inner spot of the anterior pair larger than the 

 outer, elongate-oval in shape, and marked in the middle with a 

 narrow brown spot ; the outer spot of the same pair emarginate 

 in front ; the two spots of the posterior pair elongate, with the' 

 inner one commencing before the outer and coalescing with it 

 behind. Body underneath with au ashy-grey pubescence along 

 the middle, fulvous brown towards the sides ; legs brown, more or 

 less suffused with grey at the base and on the ventral side. Inter- 

 coxal process of the mesosternum very feebly tubercled in the 

 middle. Last abdominal segment feebly and sinuately emarginate 

 at the apex. 



Antennae, longer (by the last three or four joints) than the body, 

 third joint half as long again as the fourth. 



Ceroplesis revoili Fairm. 



West (April 16 to Aug. 7, 1895) and North-west Somaliland, 

 Galadi (Oct. 4, 1897). Three examples, two from the latter locality. 



Ceratites jaspideus Serv. 



Somaliland (1S95 or 1897). Ten specimens. This species occurs 

 also in West and East Africa and in Abyssinia. 



Calothyrza pauli (Fairm.). 



Ano-plosUtha pauli Fairm. C. E. Soc. Ent. Belg. 1881, p. 121 ; 

 Ann. Soc. Ent. Fr. 1887, p. 338. 



West Somaliland, Bularli (May 24, 1895). One specimen. 



In this species and in the closely allied South-African^., jardvnei 

 White the claws of the tarsi are divaricate, and the scape of the 

 antennas is entirely devoid of a cicatrix. Both species are out of 

 place in Anoplostetha and should be referred to the genus Calothyrza 

 Thorns., with which they agree in all essential points of structure. 

 A third African species of Calothyrza has been described by 

 Dr. Gestro (Ann. Mus. Civ. Gen. (2) xv. p. 423), the remaining 

 species of this genus being the two Indian forms — C. sehestedi 

 Fabr. Ent. Syst. Stippl. p. 146 ( = C. margaritifera Thorns.) and 

 C. margaritifera Westw. 



Crossotus pluhicornis Serv. 



North-west Somaliland, Hargaisa (April 25 to 28, 1895)._ Oue 

 example. This species is found in Senegambia, in East Africa and 

 Natal, an example from the last-mentioned locality forming the 

 type of White's C. natalensis. 



Crossotus sp. 



Central or East Somaliland (1897). One somewhat rubbed 

 female specimen.
