Cornops'-' politum (Brunei)

 [Rio de Janeiro, Brazil.] 



Ypiranga, State of Sao Paulo. April, 1910. (Lliderwaldt; at 

 electric light.) One female. 



This specimen is provisionally assigned here, as it has the teg- 

 mina longer in proportion than described, but our material of 

 other species shows considerable individual variation occurs in 

 this feature. When compared with C. aquaticum, with which 

 Bruner compared this species, it is seen to be closely related, in 

 fact politum may be merely a geographic race of aquaticum. 



This specimen measures as follows: length of body, 27 mm.; 

 length of pronotum, 5.6; greatest caudal width of pronotal disk, 

 3.9; length of tegmen, 26.2; length of caudal femur, 16.6.

Geer)), Proc. U. S. Nat. Mus., x.\x, p. 662. [Sao Paulo, Brazil.] 

 1908. Pnracornops longipenne Rehn (not Paracornops longipenne (DeGeer)), 



Proc. Acad. Nat. Sci. Phila., 1908, p. 16. [Sao Paulo, Brazil] 



As we have shown elsewhere'^ DeGeer's lo7igipenne, from Suri- 

 nam, is a species quite distinct from this, in fact nearest to C. 

 longicorne (Bruner). The present author followed Bruner in 

 using the DeGeerian name for this species. As we have not seen 

 the allied C. paraguayense (Bruner), we are unable to say how 

 this species differs from that form, but the difference between 

 this species (as longipenne) and C. dorsatum (Bruner) has been 

 mentioned in the description of the latter. 



Type. — cf ; Sao Paulo, State of Sao Paulo, Brazil. September 

 14, 1900. [Acad. Nat. Sci. Phila., Type no. 5283.] 



Size slightly above the average for the genus; form as usual in the genus: 

 surface of face, ventro-cephalic section of genae, pronotum and pleura rather 

 thickly and regularly impresso-punctate. Head with normally exposed dorsal 

 section but slightly more than two-thirds of the dorsal length of the pronotum; 

 occiput and fastigium nearly flat when seen from the lateral aspect: interocular 

 space no wider than broadest section of frontal costa; fastigium rectangulate 

 when seen from the dorsum, finely but distinctly medio-longitudinally sulcate, 

 margins slightly elevated; fastigio -facial angle when seen from the lateral as- 

 pect slightly rounded subacute, facial line from interantennal region very 



'- We have elsewhere (Trans. Amer. Entom. Soc, xlii, pp. 285, 286, (1916) 

 shown that Paracornops GigHo-Tos equals Cornops Scudder.
