108 ON THE GENUS HELOTA. 



H e I o t a guineensis, nov. spec. Q. 



Closely allied to Helota africana Olliff l ) from Angola, 

 and strongly resembling it. The two specimens before me, 

 which come from Accra and Assinie (Guinea coast), show, 

 however, some differences which induce me to believe it a 

 distiuct species, but as the type-specimen of africana is 

 unknown to me, I can compare my specimens with the 

 description and figure only. In the new species the thorax 

 is shorter and broader and the sides are decidedly rounded ; 

 the punctures are widely and irregularly spread, and those 

 on the sides are as large as those on the middle; the black 

 median streak is laterally emarginate on its anterior half; 

 the base of the thorax as well as that of the elytra is very 

 narrowly edged with black. Of the elytra the smaller apical 

 half is black with a deep triangular notch at the suture , 

 the two elongate black spots on the fulvous basal half are 

 absent, and the apices are more acutely pointed. The legs 

 are black , with the exception of a broad fulvous ring at 

 the basal half of the femora , and a more or less distinct 

 spot on the middle of the under surface of the tibiae , which 

 is of the same colour. The last ventral segment shows an 

 ill-defined impression along the middle, and its apex is 

 indistinctly truncate. — Length 13 — 14 mm. 



Hah. West Africa : Accra and Assinie. — A single female 

 specimen in the collection of Mr. Neervoort van de Poll , 

 and another (that from Assinie) in the collection of the 

 Ley den Museum and presented by Mr. Ch. Alluaud.

 the Identification of Insects. PI. 153, fig. 3. — There is every probability that 

 this specimen is the one mentioned by Chapuis in the „Genera des Coléoptè- 

 res", vol. XII (1876) p. 18: «Nous avons vu, dans la Collection du célèbre 

 voyageur Welwitch, un type de l'Afrique occidentale."
