HELOTA SJÖSTEDTI. 1G5 



faintly emarginate in the middle ; in front of the trunca- 

 tion a large semi-ovate smooth impression, the top of which 

 touches the apical margin of the preceding segment. Elytra 

 conjointly though rather narrowly rounded at the apex, 

 slightly dehiscent at the suture, the posterior margin rather 

 irregularly sinuated, the sutural interstice terminating in 

 a very minute tooth, the 7 th insterstice more distinctly 

 raised than in the female. 



9- Legs simple. Abdominal segments with a single hair- 

 bearing puncture on both sides of the middle, the basal 

 segment neither impressed nor tufted in the middle, the 

 apical segment broadly rounded posteriorly and provided 

 at the apex with a smooth impression which is less deep 

 and smaller than that of the male. Apices of the elytra 

 acutely prolonged, dehiscent at the suture. 



Hab. Cameroon (West- Africa). — The specimens of this 

 species which I have before me (a cf and a 9 from the 

 Stockholm Museum of Natural History, a cT in the Ley- 

 den Museum, and a ditto from the collection of Mr. E. 

 Schenkliug at Berlin) are brought home by Prof. Dr. Yngve 

 Sjöstedt, to whom I have dedicated the species. 



Besides with the four above mentioned specimens I am 

 acquainted with three others, likewise originating from 

 Cameroon 2 ), which agree with them in almost every respect. 

 They are, however, proportionately shorter and broader, 

 and the black spot in the fulvous basal portion of the elytra 

 (which latter is somewhat shorter than the black apical 

 portion, whereas the contrary is to be observed in Prof. 

 Sjöstedt's specimens) is very distinct and well-defined. But 

 I believe these differences to be of no specific value and 

 I am inclined to regard these specimens as a mere variety 

 of Sjöstedti.
