but like the others, nests in trees. The colonies must be very large, 
judging from the numbers of workers seen together. The workers 
are able to exude from the anal glands a large drop of a mustard-yellow 
secretion. This is not, so far as I could ascertain pungent, and it had 
no effect when applied to my skin. 
165. Dolichoderus (Hypoclinea) bidens (Linné). 
Taken at Parad, Porto Velho, and Abuna. 
166. Dolichoderus (Hypoclinea) bidens (Linné) var. inferior, var. nov. 
Taken at Itacoatiara and Abunda. This variety is somewhat 
smaller than typical D. bidens, and is light ferruginous in color. The 
punctation on the vertex is much finer. 
167. Dolichoderus (Hypoclinea) analis Emery. 
Several workers were taken at Paré and Abunda. It is less common 
than the preceding species. 
168. Dolichoderus (Hypoclinea) germaini Forel var. garbei Forel. 
Many workers from Ceara and Independencia agree with Forel’s 
description of this variety from Bahia. The head has the sides little 
convex and much longer than broad; the pronotum is as broad as long. 
In all of the series the legs are light fuscous and in some of the speci- 
mens the thorax is considerably lighter than the rest of the body. 
169. Dolichoderus (Hypoclinea) ghiliant Emery.
