Coloration completely destroyed by immersion in a liquid preservative, ex- 
cept for a short, velvety black line at the base of the anal vein, and several 
fuscous clouds on the stridulating field of the tegmina. 
Length of body, 20.3 mm.; length of pronotum, 5.2; caudal width of pro- 
notal disk, 3; length of tegmen, 2S.2; greatest width of tegmen, 7.8; length 
of caudal femur, 17. 
The type of this remarkable species is unique. 
Anaulacomera bovicula new species (Plate III, figs. 13 and 14.) 
The features separating this species from A. onbos, its only 
close relative, which is described in the preceding pages, are 
given in the diagnosis of the latter species. 
Type. — cf ; Ceara iMirim, State of Rio Grande do Norte, Brazil. 
(Stanford Expedition; W. M. Mann.) [Acad. Nat. Sci. Phila., 
Type no. 5326.] 
This species is in general such a duplicate of ovibos that the 
following descriptive features are solely those of difference from 
the description of ovibos. 
Size rather small. Fastigii of the face and vertex separated by a somewhat 
greater space than in ovibos. Tegmina surpassing the apices of the caudal 
femora by nearly twice the length of the pronotal disk, in length about three 
and one-third times as long as the greatest width. Disto-dorsal abdominal 
segment in its position and development as in ovibos, but the median section 
bears a squared (in section), elevated portion, which narrows in width distad, 
■with distinct lateral margins to the same area, which also bears a medio- 
longitudinal, shallow and relatively broad sulcus, strongl}' declivent lateral 
slopes and a truncate extremity; lateral portions of the segment as in ovibos; 
cerci of the general type found in ovibos, but the thickened proximal portion is 
less pronounced and more w'eakly carinate, while the attenuate portion is 
much less extensive, the tips reaching dorsad onh' to the cereal bases, sulcate 
as in ovibos: subgenital j^late as in ovibos. Cephalic femora with three spines 
on the ventro-cephalic margin; median femora with one to two spines on the 
ventro-cephalic margin. Caudal femora with two to three spines on the ven- 
tro-external margin, ventro-internal margin with two to three spines. 
Coloration destroyed by immersion in a liquid preservative, the same l)lack 
and fuscous markings indicated as found in ovibos. 
Length of body, 14 mm.; length of pronotum, 4.6; caudal width of prono- 
tum, 2.7; length of tegmen, 24.2; greatest width of tegmen, 6.8; length of 
caudal femur, 14. 
The type is unique. 
In addition to the species of Anaulacomera here recorded, we 
have in the present series females of three other very distinct 
species, which we are unable to place in any of the forms known
