Herinannsbiirg ; and (2) from between tliese latter localities and the type 
regions of O. gurneyi snhclavata and O. gurneyi centralis respectively. Until 
some extra records arc obtained, it seems premature to name the Lalla Rookh 
example subspecifically. 
Family NOTOLIGOTOMIDAE Davis 1940b. 
Ann. Ent. Soc. America, 33, 4, p. 681. Type genus, Notoligotoma Davis 1936, 
op. cit., p. 244. 
Other genera included in this family are Metoligotoma Davis (Eastern 
Australia), Ptilocerernbia Fried. (Java and Sumatra), Ernbonycha Navas 
(Indo-China), and the fossil Burmitembia Ckll. (Burmese Amber. ? Miocene). 
The family is thus Indo-Malayan in distribution ; the feature common to all 
its members is the reduction of the second segment of the left cercus in the 
adult male, and its fusion, to a greater or a less degree, with the first segment. 
In all genera where the character has been studied, there is a medial bladder 
on the plantar surface of the hind tarsus : this is common to both sexes and 
all stages.

Loc. cit. Genotype, OUgotoma hardyi Friederichs 1914, Rec. W.A. Museum, 
1. 3, p. 241. 
Australian Notoligotomidae, males winged, or with winged and wingless 
forms in the same species ; M, and Cu;ia simple, the first two well- 
developed ; cross-veins relatively frequent ; tenth abdominal tergite com- 
pletely divided to hemiteigites, separated basally by a trapezoidal median 
sclerite. Right hemitergite with a postero-median process and an inner 
process, stout and echinulate, curving forward from the anterior end of its 
inner margin. Inner margin of left hemitergite produced back to a long thin 
subacute process. First segment of left cercus clavate and echinulate, second 
less than twice as long as its average thickness, firmly set on the outer and 
distal part of the first segment and not movably articulated thereto. Left 
cercus-basipodite fused to left-hand margin of hypandrium, terminally pro- 
duced to a subobtuse process. 
Both sexes with two bladders on plantar surface of first segment of hind 
tarsus, one medial, the other terminal. (The medial bladder possibly indicates 
the position of the end of one segment, the basal segment thus being formed of 
two segments of an ancestral condition closely fused ; this view is supported 
by the fact that the medial bladder is present in all those genera which on 
other characters are regarded as primitive.)
