3-i8 AXNALS OF THE CaRNEGIE MuSEUM. 



mm., width of tegmina, l6 mm., length of hind femora, 40 mm., of 

 ovipositor ^2 mm., width of o\ipositor, 6 mm. 



Habitat. — The type, a beautiful female specimen, was taken at 

 Quatro Ojos, in the Department of Santa Cruz, Bolivia, during the 

 month of November at an elevation of 300 meters above sea-level. 

 (J. Steinbach.) It is the property of the Carnegie Museum. 



82. Acanthodis tenebrosa (Brunner). 

 Brisilis tenebrosa Bruxner, Mon. Pseudophyll., pp. 132, 134 (1895). 

 Acanthodis tenebrosa Kirby Syn. Cat. Orth., II, p. 319 (1906). 



A single female of this species is contained in the collection made 

 at Puerto Suarez, Bolivia. It was also taken by J. Steinbach during 

 the period November to January inclusive. It is quite typical. 



Genus Pristes Brunner. 

 Pristes Brunner, Mon. Pseudophj^ll., pp. 16, 135 (1895); Saussure & Pictet, Biol. 

 Cent.-Amer., Orth., I, p. 411 (1898). 



This small genus of the Pseudophyllida^ seems to be confined to 

 northern South America and Central America. It is represented by 

 two female specimens which appear to belong to a new species inter- 

 mediate between the two described forms. The species of Pristes, 

 including the present, may be recognized as follows: 



Synopsis of the Species of Pristes. 

 A. Pronctum between the tubercles granular. 



b. Sternum black. Size larger tiiherosus Stal. 



bb. Sternum brcwn. Size smaller colombicB sp. nov. 



AA. Pronotum between the tubercles almost smooth. Sternum concolorous. 



minor Brunner. 

 S3. Pristes colombiae sp. nov. 



As indicated by the above table, this insect is intermediate between 

 tuberosns Stal and minor Brunner. It is rather dark fusco-testa- 

 ceous, varied with green on the tegmina along the costal field near the 

 base and the median veins, and marked with dark fusco-cinereous on 

 the legs. On the tegmina near the base of the disc is located a patch 

 of ochraceous blotches, while the outer side of the hind femora are 

 also rather largely testaceous on their middle one-third. Front, 

 including the clypeus, brunneo-piceous, bordered with testaceous; 

 cheeks and occiput longitudinally alternately pale and dark banded. 



Length of body, 9 , 49 mm., of pronotum, 11 mm., of tegmina, 56 

 mm., width of tegmina about 13 mm.; length of hind femora, 33 mm., 

 of ovipositor, 30 mm.
