THE JANEIRENSIS GROUP OF THE GENUS EUBORELLIA, 
WITH THE DESCRIPTION OF A NEW SPECIES 
(DERMAPTERA) 
BY MORGAN HEBARI) 
While ill iMiaiiii, Florida, early in Uk* aulhor aj^aiii 
visited the nuui^rove swamp on the border of Briekell’s Ilani- 
nioek, for the i)iirpose of securing additional material of several 
int('r(\sting species of (trthoptera which, in 1!)15, had been found 
ilu'rein, — i. e. Hygvonemohim (lUcni (iMoi-se), Anaxipha .scia Ileb- 
ard and .1 naxipha itniintor (Saussure.)i While searcldng for s])ec- 
imens of the second species, about the mangrove shoots which 
projected from the muck and tidal litb'r, some of tlu' la.t(('r 
was overturned and a si)ecimen of EuborcUia i-(*vealed. This imli- 
vidual soon was seen to be different from aniiuUpcs (Lucas), 
the only species of the genus hitherto known from the Fnitc'd 
States, and vigorous efforts were vainly made to find oilu'iu'xam- 
ples. Several days later the spot was rc'visited and yai'ds of ( he 
litter carefully lifted and sifted. Hours of such work ix'sult- 
ed in our securing five males, three females and several imiuature 
specimens of the species. These were found under s('aw('('d and 
sea-grass, drifted in to the ('dge of the normal high tide, us- 
ually between the lower matted layers, neai' the w(d, mucky 
ground. The species was local, l)ut never in colonies, as is us- 
ual (ov Anisoldhis maritima ((lene), two sp(‘cimens of which w(‘re 
found in the same place. Tlu' arc'a in which the sp('ci('s occuri'c'd 
is shown in the accompanying illustrations (pi. Will, figs. I 
and 2). 
Comparison of this mab'rial with a temale of hiihorcUni 
ainbig'Ka (Boi'clli),” from Santa INfaria d(' Dota, ( osta Kica, 
shows full agreement. Further com])arison ol material con- 
vinces ns that the est Indian seric's, i'(*cord('d by Ib'hii and 
Ilebard as E. anibigiia, represeids a distinct, though very clost'ly 
related, species.
