nal spine moderately robust, pyramidal, directed gently to the rear. 

 Valves of the ovipositor very unequal, the upper ones nearly twice as 

 long- as the lower, straight, and provided with several small saw-like 

 teeth along their outer edge on apical half; lower valves weak and 

 hooked at apex and furnished below with a single additional subapical 

 tooth. 



Length of body, female, 26; of pronotum, 6; of tegmina, 19; of 

 hind femora, 13.5; of upper valves of ovipositor, 4 mm. 



Ti/pe.— Cat. No. 9750, U.S.N.M. 



Habitat. — A single female specimen from Sapucay, Paraguay. 



The character of the ovipositor would indicate an abnormal egg- 

 laying habit for this and allied species. Three such are known to me. 

 They may be separated by the annexed 



TABLE FOR DETERMINATION OF 8PECIES. 



a. Hind tibise green or glaucous. Valves of ovipositor tapering, scarcely toothed. 



impudica Giglio-Tos 

 act. Hind tibiae coral-red. Valves of ovipositor of nearly equal size throughout, 

 plainly serrate. 

 6. Smaller (female, 26 mm.). Spines in outer row of hind tibiae 8. ■ (Sapucay, 



Paraguay) mbripes, new species 



bb. Larger (female, 31; male, 18 mm.). Spines in outer row of hind tibiae 9.

PARASCOPAS, new name. 



PARASCOPAS OBESUS (Giglio-Tos). 



Scopas obesus Giglio-Tos, Boll. Mus. Zool. Anat. Comp. Torino, IX, 1894, No. 

 184, p. 29. 



Giglio-Tos proposed Scopas as the generic name for this insect. 

 As it had been preoccupied by Bonapart for a fish genus I suggest 

 that Parascopas be used for the locust, and that the species obesus 

 Giglio-Tos be made the type of the genus. 



The collection contains 5 specimens, 2 males and 3 females, from 

 Sapucay (Coll. U. S. Nat. Mus.). There are also a pair, male and 

 female, in the collection of L. Bruner. These latter bear the same 

 label. 



« Some time ago a considerable number of Orthoptera, from southern Brazil was 

 submitted to the writer for determination. Among these were 8 specimens of the 

 insect here tabulated. Aside from being larger and more robust than S. rubripes, 

 which is herewith described rather fully, this Brazilian species has the tegmina 

 more densely veined and the pronotum somewhat expanding posteriorly through- 

 out, as indicated by the diverging pale vittae of the disk. The lower sulcus and 

 inner face of hind femora are deep red, whereas in rubripes they are simply tinged 

 with orange. As compared with S. impudica Giglio-Tos, brasiliensis has the two 

 sexes greatly unequal in size, as will be seen by the following measurements: 



Length of body, male, 18-20, female, 31; of pronotum, male, 4.75, female, 6.8; of 

 tegmina, male, 16, female, 22; of hind femora, male, 11.5, female, 16 mm. Eight 

 specimens, 4 males and 4 females.
