MANN: THE ANTS OF BRAZIL. 481 



Many workers were taken at Ceara-Mirim,' Natal, and Maranhao, 

 from nests beneath stones. 



211. Camponotus (Myrmobrachys) crassus Mayr. 



This was the commonest of the genus on the east coast, where many 

 workers, females, and males were taken at Natal, Ceara-Mirim, 

 Baturite Mountains, and Maranhao. 



212. Camponotus {Mynnomalis) depressus (Fabricius). 



Plate 5, fig. 42. 



Taken at Abuna, Bolivia and Madeira-Mamore Camp 39. This 

 is one of the most singular ants, on account of its very elongate, flat 

 body and the extremely long legs. The few workers which I ob- 

 served were running about on leaves. 



213. Camponotus (Myrmepomis) sericeiventris (Guerin). 



Abundant on the Rio Madeira at Abuna and Camps 39 and 41. 



Some years ago Mr. E. J. Newcomer gave me a live worker major 

 of this species which was found in a restaurant at Palo Alto, Cali- 

 fornia, having no doubt been imported with bananas from Central 

 America. 



214. Camponotus (Myrmorhachis) latangulus Emery. 



Workers from Para, ]\Ianaos, and Madeira-Mamore Camp 39 are 

 a trifle lighter in color than a series from Peru, but are otherwise 

 identical. 



215. Camponotus (Myrnieurynota) heathi, sp. nov. 

 Plate 5, fig. 40, 41. 



Worker major. (Plate 5, fig. 41). Length 5.5 mm. 



Head nearly as broad as long; sides straight from occipital corners 

 to three fourths the distance to anterior border, then concave; rounded 

 anteriorly. Occipital corners broadly rounded, the margin nearly 

 straight. Frontal carinae narrow, not much elevated. Frontal area 

 broad, slightly convex, anteriorly as broad as the base of clypeus,
