Newportia Gervais. 



Insect. Apteres, 1847, 4, p. 298; Kraepelin, Revis. Scolop., 1903, p. 76; Ver- 



hoeff, Bronn's Thierreich, 1907, 5, p. 251. 

 Newportia + Scolopendrides, Saussure, Rev. mag. zool. 1869, ser. 2, 21, p. 158. 



This genus, peculiar to tropical and subtropical America, is repre- 

 sented in Brazil by seven known species, of which four have been 

 previously recorded. Of the three here first listed from Brazil, two- 

 are described as new. In addition, Scolopocryptops aurantiaca and S. 

 viridis Gervais (Insect. Apteres, 4) are probably based upon members 

 of the present genus; but there is nothing in the original descriptions 

 to make precise identification possible, and the names must be dropped 

 until the t^^jes are examined, if they now be in existence.

 with a fine and distinct transverse sulcus; sulci of second 

 dorsal plate evident from anterior margin caudad to or 



past the middle of plate A'', ernsti Pocock. 



cc. Paired longitudinal sulci of head not crossed near base by 

 any such transverse sulcus; sulci of second dorsal plate 

 not evident on anterior half, being present only as short 

 lines at caudal border which bifurcate into a very short
