462 Descriptive Catalogue [1896. 



Stenolophus alacee. 



Palpi, legs, the two basal joints of antennae flavescent, the other 

 joints slightly infuscate, labrum, clypeus and prothorax dark-red ; 

 head black, smooth, shining; prothorax with a broad lateral de- 

 pression on each side of the base ; elytra oblong, black, iridescent, 

 suture and outer margin narrowly edged with red ; under side flaves- 

 cent, abdomen infuscate. Length 4 mm. ; width If mm. 



Hah. Natal (Frere) Zambezia (Salisbury). 



In some examples from Zambezia, the sutural reddish band is 

 a little broader than in the Natal ones. 



Stenolophus simplex. 



Palpi, labrum, and legs, the two basal joints of the antennae flaves- 

 cent, the other joints slightly fuscous ; prothorax light piceous 

 with the sides rufescent, smooth, shining, with neither the posterior 

 depressions nor the base aciculate ; elytra oblong, black, iridescent, 

 with the suture and the edge of the outer inargins very narrowly 

 rufescent ; under side fuscous. 



Closely allied to S. alacer, but the colour of the prothorax is 

 different, and the sutural and marginal bands narrower and not so 

 red. Length 4-4f mm. ; width 1|~2 mm. 



Hab. Natal (Escourt, Tugela Eiver). 



Gen. ACUPALPUS, Latreille, 

 Eegn. An., ed. 2, iv., 1829, p. 391. 



The generic characters are almost entirely like those of Stenoloi^lius. 

 The difference is found in the shape of the ligula, which is more 

 triangular at the apex, but it is doubtful if this character would hold 

 good in all the species, and also in the shape of the joints of the 

 intermediate tarsi, for, although in some species the fourth joint of 

 the anterior tarsi of the inale may be as lobate, in the intermediate 

 ones this fourth joint is only incised ; the terminal joint of the labial 

 palpi is fusiform, much inflated in the centre, and very sharp at the 

 tip ; the last joint of the labial palpi of the male often shows a very 

 peculiar depression, but I cannot say that I have found this a 

 permanent character in the South African species. 



The species contained in Acupalpus are found in Europe, Northern 

 and Southern America, India and Africa. 



Synopsis of Species.
