crana Serv. , and the genera which I have separated from Pygidi- 

 erana, namely Dicrana, Cranopygia, Picrania and Pyge and also tlie 

 apterous Dacnodes Burr. 



It is represented in all tropical regions and species are 

 fairly numerous. 



The three genera Pyragra, Echinopsalis and Echinosoma which 

 were placed by Verhoeff in the Pygidicranidae , I prefer to place 

 in the Lahiduridae. 



Family 3. Labiidae. 



The revision of this family is not yet complete and so I 

 hesiatate to offer a premature System. 



It is allied to the Forficididae , differing in the simple form 

 of the second tarsal segment (see fig. 4). It will include the 

 Nesogastrinae^ revised recently (Ann. Mag. N. H. [8] i. p. 42 [1908]), 

 with the Single genus Nesogaster^ including eight species, most of 

 which were formerly included in Labia. Nesogastrella of Verhoeff 

 falls, being founded on an imperfeet female of Labia amoena Stäl., 

 which is a true Nesogaster. 



It will also include Strongylopsalis Burr , with two known 

 species (v. Burr 1. c. p. 49). 



A new genus and subfamily must be erected here for the 

 anomalous from Labia tenuipes Burr, from Peru (Ann. Mag. N. H. 

 [7] XVI, p. 487 [1905]). 



Spongiphora and Labia will together form another subfamily; 

 both these extensive genera include heterogeneous material and 

 several new genera must be formed , for the following species 

 must probably be separated into new genera : Spongiphora frontalis 

 Dohrn, remota Burr and divergens Burr, Spongiphora decipiens Kirby 

 and sphinx Burr, Spongiphora rogersi Borm. and geayi Burr, Labia 

 canaca Burr, with several of the old species of Spongiphora, Labia 

 Paraguay ensis Caudell, arachidis Yers. and rotundata Scudd., Mecomera 

 kervillei Burr and loeissi Burr. 



The depressed forms Sparatta, Platylabia, Chaetospania and Me- 

 comera, will probably require a new subfamily. 



The old genus SpMngolabis Borm. , with S. semifidva Borm. 

 (= furcAfera Borm.) as type , including S. hawaiiensis Borm. will 

 probably be placed near here. 



This affinity was unconsciously recognised by the Bormans, 

 when he described „Sparatta semifidva" and „SpMngolabis furcifera", 

 which are the two sexes of one species ; also his „SpMngolabis 

 borneensis" is a Chaetospania. 



The affinities of the Labiidae are with the Forficulidae , the 

 essential distinction being the structure of the tarsi.
