The type of D. Juncea, Sauss. (Rev. Zool. 1864, p. 314:), 

 appears to represent a dark form of this species. 



Deropeltis similis.

 1, Zomba {Rendall). East London (Nat. Hist. Mus.). 



Tlie legs and pronotura vary somewhat in colour in different 

 specimens. The specimens from Barberton and one of those 

 from Pretoria represent a form of the insect which stands in 

 the same relation to typical D. similis that D. brevicollis 

 occupies towards D. jancea. D. foveolata is a dark form 

 with the pronotum alone uniform black. 



Deropeltis capensis.

1, Teafontein, Cape Colony ; Cape (Brunner) ; Natal, 

 Port Elizabeth (Nat. Hist. Mus.). 



A conspicuous species with a yellow border to the pronotum. 



Deropeltis Distanti, sp. n. 



Long. corp. 17 millim. 



Female. — Black, shining, especially the head ; lower 

 mouth-parts yellow ; a small yellow dot above the base of 

 each antenna; antennae dark chestnut-brown, shading into 

 rufo-testaceous beyond the middle ; pronotum finely cribratc- 

 punctate, the rest of the upper surface nearly smooth ; pro- 

 notum with rather broad lateral orange borders, not extending 

 to the hind border ; mesonotum with the lateral carina 

 reddish ; metanotum with a rufo-testaceous spot at the base, 

 on each lateral margin, and a similar spot on the sides of the 

 second abdominal segment (the tirst segment being covered 

 at the sides by the metanotum) ; cerci dark rufo-testaceous, 

 set with long fine hairs ; legs rufo-testaceous and middle of 

 abdomen beneath reddish. 



1, Pretoria {Distant). 



Allied to D. meridionalis^ Sauss., but larger and differently 

 coloured. 



Until the sexes oi Deropeltis are better known, it is almost 

 impossible to unite them in our collections with anything 

 approaching certainty.
