MANN: THE ANTS OF BRAZIL. 481 
Many workers were taken at Ceard-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, Ceard4-Mirim, 
Baturité Mountains, and Maranhao. 
212. Camponotus (Myrmomalis) depressus (Fabricius). 
Plate 5, fig. 42. 
Taken at Abund, Bolivia and Madeira-Mamoré 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) sericetventris (Guérin). 
Abundant on the Rio Madeira at Abuné 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 Parad, Manaos, and Madeira-Mamoré Camp 39 are 
a trifle lighter in color than a series from Peru, but are otherwise 
identical. 
215. Camponotus (Myrmeurynota) 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,
