than in williamsi (Fig. 3). The tegminal pads in cribrosa are 
attingent and uniformly colored. The costal margins of the tegmina 
of williamsi are brownish yellow and the pads are distinctly separated 
from one another. The abdomens of both species are punctulate, but 
the punctulations are fine in cribrosa and coarse in williamsi. 
Measurements for both species are given in Table 1. 
Princis (1963) placed Galiblatta in the Laxtinae. McKittrick 
examined a male of G. williamsi and stated (personal communica- 
tion) that it belongs in the Epilamprinae of her classification (Mc- 
Kittrick, 1964). 
Type cT (No. 70220), allotype $, 4 male paratypes (type and 
paratypes reared from the allotype $) and one male nymph are 
deposited in the U. S. National Museum. 
Type locality: Taruma-Agu (along a secondary river leading into 
the Rio Negro) about 15 Km. northeast of Manaus, Amazonas, 
Brazil. 
The species is named after Dr. Carroll Williams, who headed 
Phase C of the Alpha Helix Expedition to the Amazon.
