I have not seen this species, which from the above characters 

 can scarcely belong to the genus Staccia. In fact, Stal himself, 

 who at the time of writing his fourth instalment of his ' Enume- 

 ratio Hemipterorum ' had not the type before him, placed it in 

 his ' Species Stenopidinoi"um iucerti generis.' I have thought it 

 best, however, to record the species in this place. 



Genus DIADITUS. 



Diaditus, Stal, Ofv. Vet.-Ak. Fork. 1859, p. 383; id. Hem. Afi: iii, 

 p. 150 (18(jo) ; id. En. Hem. ii, p. 124 (1872; ; Chcwip. Biol. 

 Centr.-Am., H/ujnch. ii, p. 188 (1898). 



Type, D. semicolon, Stal, a Neotropical species. 



Distrihution. Neotropical and Oriental Kegions. 



Body oblong, narrowed anteriorly ; head cylindrical, anteocular 

 portion a little longer than the postocular, antenniferous tubercles 

 prominently subspinously produced, with two porrect spines 

 between them ; antennae with the first joint shorter than the 

 head ; rostrum with the first joint about as long as the two apical 

 joints togetlier ; legs slender, anterior femora a little incrassated, 

 posterior femora not or nearly reaching abdominal apex ; scutellum 

 with a horizontal a])ical spiniform process. 



In the Ceylonese species here included, the antennae are peculiar 

 in liaving the third joint very shoi't and subnodulose, a character 

 not exhibited in the American species as at present known.
