HENRY J. FRANKLIN. Ill 



this species or not. Handlirsch's types of carbonarhis are in 

 the collection of the k. k. Hofmuseum at Vienna, Austria. 



Pile of medium length a7td texture. Black. Wittgs dark, zvith vio- 

 laceous reflections. Malar space long. 



Queen. Head. — Rather elongate and black. Mandibles as in the 

 Pratoruvi group. Malar space distinctly longer than its width at apex, 

 about two-fifths as long as eye. Clypeus moderately punctate with 

 rather coarse punctures. Third antennal segment somewhat longer 

 than fifth, the fifth somewhat longer than the fourth. 



Thorax. — Clothed with black pile ; the very center of the dorsal disc 

 naked and smooth. 



Abdomen. — Both dorsum and venter black. Hypopygium without 

 median carina. Epipygium with a low, but distinct, longitudinal me- 

 dian carina on its apical two-thirds. 



Wings. — Very dark and with violaceous reflections. 



Legs. — Dark and with black clothing. 



Worker. — Like the queen, but without median carina on epipygium. 



Male. — Like the females in coloration. Mandibles with black beard. 

 Antennae very long, their segments feebly arcuate ; third segment very 

 short, cone-shaped, nearly three-fourths as long as the fourth, the 

 fourth three-fourths as long as the fifth. Hind tibiae flat on their outer 

 sides and almost entirely naked in the middle of those sides ; metatarsi 

 of the hind legs short haired. Hypopygium slightly bent up at the 

 end and fringed with light, moderately long hairs. 



Genitalia.— Branch long ; squama divided into two lobes and con- 

 siderably reached by the volsella drawn out into three nearly equal pro- 

 cesses ; sagittse bent outward and hook-shaped at end. 



Dimensions .—Length : queen, about 21 mm. ; worker, 14 mm. to 18 

 mm. Spread of wings: queen, about 50 mm.; worker, 32 mm. to 

 40 mm. Width of abdomen at second segment : queen, about lOj 

 mm. ; worker, about 7 mm. 



I have here redescribed the queen from a single specimen 

 and the worker from three specimens. I have not seen the 

 male, but have made up the description of that sex, here 

 given, from a translation of Handlirsch's description. 



Habitat. — I have apparently certain records for this species 

 as follows: Brazil (Rio de Janeiro, Rio Grande, Ypanema, 

 Sao Paulo) ; Paraguay (Sapucay, Asuncion, Trinidad, Villa 

 Encarnacion); Argentina (Tapia — 600 meters altitude); Peru 

 (Callanga); Ecuador (Santa Inez) and Venezuela. Ducke 

 has recorded it from Macapa, Brazil.
