These specimens apparently represent the previously undescribed 

 male of the species. As far as can be determined from the ambi- 

 sexual characters given in the original description, our individuals 

 are conspecific with the female described by Brunner. The stridu- 

 lating field of the male tegmina is elongate and relatively narrow, 

 bearing two very conspicuous, ivory-white, subcircular areas, sur- 

 rounded and separated by a border of ox-blood red. The margin of 

 the disto-dorsal abdominal segment is faintly arcuato-emarginate 

 distad, while the supra-anal plate is of uncertain form, being buried 

 by the flexed cerci; the latter are simple, tapering, deplanate distad, 

 .straight in the proximal two-thirds, then moderately arcuate in- 

 wards, the apex blunt; subgenital plate rather short, narrowing dis- 

 tad, with a distinct median carina, the distal margin truncate with 

 the lateral angle produced into distinct, acute, substyliform pro- 

 cesses. A representative specimen measures as follows: length of 

 body, 14 mm.; length of pronotum, 4.3; length of tegmen, 25.5; 

 greatest width of tegmen, 5.6; length of caudal femur, 17.5 . 



The localities given above are apparently the only ones from 

 which the species has been reported, Bruner having already re- 

 corded it from Chapada.^" 



Anaulacomera bellator new specie.s. (Plate X, figs. 21 and 22.) 



Closely related to A. intermedia Brunner (plate X, fig. 23), with 

 .a male of which we have compared the new species, but differing 

 in the more roundly deflected lateral lobes of the pronotum, the 

 more narrowly rounded tegminal apices, somewhat longer limbs and 

 more strongly divergent sections of the male cerci, these divided 

 more proximad and the ventral section of which also carries on it 

 ■dorsal surface a short supplementary spine. 



^^ We find that the species described by us as Hjiperophrona signata (Peoc. 

 Acad. Nat. Sci. Phila., 1907. p. 382, figs^ 14, 1.5 and l«i, (1907)), from Sapucay, 

 Paraguay, is not a member of that genus, but instead an aberrant Anaulacomera, 

 more nearly related to A. brevicauda. From the latter species signata differs in 

 the proportionately broader tegmina, which are regularly elongate ovate, in the 

 less slender limbs, the more sharply hooked cereal apices and the distinctly 

 broader tymi:)anal field of the male tegmen.
