tegmen, 38.8; greatest width of tegmen, 8.5; length of caudal 
femur, 28.2; length of ovipositor, 9.6. 
The species was previously known only from the type locality. 
Euthyrrhachis gracilis Brunner 
1878. E[uthyrrhachis\ gracilis Brunner, Monogr. der Phaneropt., p.331, pi. vii, 
fig. 95. [Paraniaril)o, Surinam.] 
Porto \'elho, Rio Madeira. (IVI. Bolton.) One female. 
Igarape-assii, Pard. (H. S. Parish.) One male. 
In the original description Brunner states that the cephalic 
and median femora are unspined ventrad, but later he modifies 
this to “submutica” and “raro-spinulosa. In both of the 
present specimens the ventro-cephalic margins of the cephalic 
femora have two to four, and of the median femora, four spines. 
The ventro-external margins of the caudal femora bear six spines 
in the female and six to seven in the male; the ventro-internal 
margins of the caudal femora bear seven to nine spines in the 
female, six to seven in the male. 
The species has been previously recorded from Paramaribo, 
Surinam and Fonteboa, upper Amazonia. 
Scaphura nigra (Thunberg)

Baturite Mountains, Ceara. (W. M. Mann.) One female. 
This specimen is similar to that described by Perty as ferru- 
ginea,^ except for the restriction of chaljdjeous on the abdomen 
to mere edgings on the proximal segments and its complete 
absence from the limbs, while the ochraceous patch on the ventral 
section of the lateral lobes of the pronotum, mentioned by Perty, 
is well marked. It is somewhat smaller than the average from 
southern Brazil and Paraguay, but tloes not appear separable from 
those from more austral localities.
