Lahiduridae, a family of the Bermmptcra. 169 
Wales. Perhaps we may later be able to discriminate two 
species. 
Genus 2.— Gonolabis, Burr. 
The genus Gonolalm has been subject to two distinct 
sources of confusion. 
First Verboeff's characterisation of his sub-family Gono- 
laMdae, with G. lativentris as type, excluding by this very 
characterisation G. javana, which liad been originally 
chosen as type. 
Secondly the doubt as to the identity of the true 
G. javana, under which name no less than three species 
have been confused in collections. 
The first confusion has been cleared up by the separation 
of Verhoeff’s '' Gonolahidae” into a separate sub-family, the 
Esplialmcninac. (See Burr, 1909^.) 
The second confusion is now cleared up, thanks to the 
courtesy of Dr. Gestro of Genova and Dr. Holdhaus of 
Vienna, who have kindly communicated the respective 
types of G. sumatrana, Borm., and G. javana, Borm. 
Thus I have been able to examine authentic specimens 
of every known species of the genus, the catalogue ot 
which now stands as follows:— 
1. G. Idrhyi, Burr, Java. Type examined. 
2. G. electa, sp. n., Java-Ceylon. Type examined. 
3. G. sumatrana, Bonn., Java and Sumatra. Type 
examined. 
4. G. ohlita, sp. n., Java. Type examined. 
o. G. javana, Bonn., Java. Type examined. 
6. G. michaelscni, Burr, Australia. Type examined. 
7. G-incea, Borelli, E. Africa. Syntype examined. 
8. G. moodwardi. Burr, Australia. Type examined. 
9. G. verhopffi., Burr, Australia. Type examined. 
From this list will be observed that I have been able 
to examine and compare the types of every known species, 
except G. picea, and of that authentic syntypes kindly 
given me by Dr. Borelli, which is almost the same thing. 
It will also be noticed from the above list that the 
genus is chiefly characteristic of the Oriental and Aus¬ 
tralian regions, a single species occurring in the Etliiopian 
region.* 
* Since writing the above I have seen the type of Anisolabis 
azteca, Dobrn, from Mexico : it is a female, but evidently a Gonolabis. 
It will be discussed in a later paper.
