Paratropus chelonitis^ sp. n. 



Brevitcr ovalis, nigro-piceus, supra impunctatus, vix nitidus ; elytris 

 striis dorsalibus 1-4 intcgris, 5 versus, suturali ultra medium 

 abbroviatis ; propygidio basi tcnuissime punctate.

In outline this species is much less oval than P. ovides, 

 Mars., from Senegal, of which there are three examples in 

 the Museum of Paris, but otherwise the excellent figures in 

 MarseuPs monograph well represent the sculpture both above 

 and below. I have seen specimens of P. chelonitis labelled 

 P. testudoj Gerst., but the elytral striaj differ from Gerstacker's 

 species in the first four being complete. Gerstiicker, in 

 counting the dorsal strise, called the sutural the first ; his 

 third and fifth stride correspond, therefore, with the fourth 

 and second of Marseul and other writers on tlie Histeridee. 

 Marseul (Ann. Soc. ent. France, Bull. p. Ixvi, 1871) recorded 

 this species, of which there is a single specimen in the 

 Museum of Paris, as referable to P. testudoy but the subjoined 

 diagnosis of Gerstacker^s will show he was mistaken. The 

 Pelorurus also noticed by Marseul (/. c.) from Abyssinia was 

 described by Schmidt in 1890 as P. formosus ; there are 

 specimens also of it in the Paris Museum. Pelorurus 

 glaucopterus, Mars., which I have lately received from Beira, 

 IS much larger than P. formosus and has a red pygidiam.

Above, this species is extremely similar to P. discisus, Er., 

 but it is narrower in form generally, the lateral margin of 

 the thorax is less wide and the punctuation of its surface is 

 finer and much more sparse, especially behind the transverse 

 sulcus, and the inner elytral oblique stria is well marked and 

 sulciform j in P. discisus the stria is obsolete. The elytral
