ANECHURA. 



This generic name (^w^iyo), oopd) is proposed for the single Pa- 

 brician species, bipunctata. It approaches the gerontogeic Opistho- 

 cosmia, and is remarkable for the great breadth of its thoracic sterna, 

 and especially of the metasternum, which is broader than long. The 

 antennse are 11-12 jointed. The legs are long, the middle pair 

 especially approacliing the hind legs in length, at least in the female; 

 these legs are also inserted almost, or quite as near the hind legs as 

 the fore legs, as in certain species of Forficula proper. The abdomen 

 is plump and dilated, and has a small tubercle on the sides of the 

 fourth and fifth ventral segments of the male; the forceps are simple 

 in the female, but strangely contorted' in the male, bearing a superior 

 basal tooth or angulated shoulder, beyond which the arms are curved 

 strongly downward, and then bent backward. It belongs to Europe. 



ANISOLABIS. 



1853. Fieber, Lotos, ill, 257: proposes this name for two European 



species — marilima and moasia, which are strictly congeneric. 



Maiitima may be considered as the type, since it it the best 



known and older of these two, and on account of its being 



absolutely apterous, like most of the other sjjecies which must 



be added to the group. 



No reference is made to this naine in Marschall's Komenclator 



Zoologicus. The genus is widespread, occurring in both hemispheres, 



and in Australasia. See also Forcinella and Brachylabis. 



APACHYS. 



1831. Serv., Ann. Sc. Nat., xxii, 35 [Apachyus]: depressus Pal.- 



Beauv. (sp.) is the only species, and therefore type. 

 1839. Serv., Orth., 54 [Apachya]: the same. 

 1846. Agass., Nom. Zool. Ind., 27: corrects the spelling as above. 



Two species have since been added by Dohrn. The genus belongs 

 to the tropics of the Old World. 



APTERYGIDA.* 



1839. "Westw., Class. Ins., i, 406: proposes this name for Gene's 

 section b, of Division ii of P^orficula,^ including the species
