250 Mr, ^f. Burr — Notes on the Forficularia. 



The second important feature is that the pygidiuin is fused 

 with the last dorsal segment. 



Now the latter character is not peculiar to this <2;roup ; it 

 marks also the fullowing genera : — Pi/rnjira, Echiriopsjlisy 

 Echinosoma, Forcipula, AllosfefhuSj Labidara^ Psali'i, Lahi- 

 darodes, Card nop kora, Anisolalns, and the six genera of tlie 

 Brachylabiiiai referred to in these pages (' Annals,' vol. ii. 

 p. 247, 1908). It is, in fact, the distinguishing feature of the 

 family Labiduridie, which includes all the genera mentioned 

 above, and falls naturally into several subfamilies. 



In an earlier note on the Gonolabidye ( Tr. Ent. Soc. 

 London, 1904, p. 293) I have pointed out that tliis narrowing 

 of the prosteriium occurs in G. peirintjuey'i^ G. sllvestrli, 

 G. lativentris, but not in G. kirhyi nor in G.javana ; conse- 

 quently, by his characterization of the Gonolabid^e, VerhoefF 

 excludes the latter species. Tiiis is unfortunate, because 

 when I erected the genus Gonolahis (Ann. Soc. Ent. Belg. 

 xliv. p. 48, 1900), I specially mentioned G. Javana as the 

 type of this genus. 



VerhoefF was evidently unfamiliar with the literature of 

 the subject, relying almost, if not quite, entirely on de Bor- 

 mans's monograph. Consequently he falls into the curious 

 error of quoting (/. c. p. 7) ''Gonoluiis {Burr) et mihi" and 

 on the next page " Typus : G. lativentris Pliil." We must 

 now se[)arate " Gonolahis Burr " from " Gonolahis niihi " ; 

 the former has a parallel prosternum and the type is G.ja- 

 vana, the latter has a narrow prosternum and the type is 

 G. lativentris. 



A new name is required for " Gonolahis mihi,^^ for which I 

 propose Esphalmenus*, with G. lativentris as type. 



The Gonolabidai of VerhoefF, therefore, does not include 

 the genus Gonolahis, and must be replaced by the name 

 Esphalmenin^e, reducing the rank to that of a subfamily. 

 There is a second genus in this subfamily, namely Gonolabina, 

 Verb. Like most of that author's names, there is a lack of 

 originality in it ; this is more unfortunate since this genus 

 really belongs to the Esphahneniiife, and has no connexion 

 with GonoLhis, which genus does not require a separate 

 subfamily, but falls into the Anisolabinae. 



Subfamily Espsalmenixjs, nov. 



Gonolabidce, Verhoeff, SB. Ges. naturf. Fr. no. 1, p. 7 (1901); Burr, 

 Tr. Ent. Soc. Loudon, p. 293 (1904). 



Apterous; antenna?, feet, and pygidiura as in Labiduridse 

 generally ; prosternum strongly narrowed posteriorly. 



* Fast. part. Greek : a-fpciWo), to make a mistake.
