Mr. M. Burr — Notes on the Forficularia. 255 



Pygidium $ short and square, slightly narrower at the 

 apex than at the base and sharply truncate, black. 



Forceps ^ with the branches red, varied with black, some- 

 what dilated at the base, with a small tooth on the inside at 

 the end of the dilated part, then straight and smooth, the 

 apices meeting. ? with the branches red, varied with black, 

 straight, conical, smooth, contiguous. 



Patria. Ecuador, camp above Chimbo, 3000', VIII. '97, 



This little species is somewhat like L. mucronata. Its 

 most noticeable points are its brilliant sliining appearance and 

 the form of the pygidium and forceps of the male. 



Spongophora croceipennis (Serv.). 

 Paramba, 3500', IV. '97 (dry season), \ S- 



Spongophora remota (Burr). 



Chimbo, 1000', VII. '97, 1 S (type) ; Cachab^, low, 

 I. '97, 1 c?, 1 larva; Cachab^, low, XII. '96, ? (type); 

 Cachab^ to Paramba, II. '97, 2 mutilated specimens. 



Spongophora dhergens (Burr). 



Cachabe, low, XI. '96, 1 c?, 1 ? (type) ; Paramba, 3500' 

 (dry season) , 1 cJ . 



The above two species were described by me in this Maga- 

 zine * as Forfimla ? ; but a lurther examination reveals a 

 deep and long transverse depression on the occiput, showing 

 close relationship with S. frontalis^ Dohrn, to which M. de 

 Bormans called my attention. They must therefore be in- 

 cluded in the genus Spongophora. 



Opisthocosmia amazonensis, Borm. 

 Paramba, 3500', V. '97, 1 ? (type). 



II. — Aptebtoiba or SpSINaOLABIS? 



The name Apterygida has been generally rejected by ento- 

 mologists, while Sphingolahis has been universally accepted. 

 The cause of this was Scudder (5), who wrote in 1875 that 

 " Apterygida has no raison d^^tre, and therefore must fall." 

 Now Apterygida has a raison d'etre, and, as I will endeavour 

 to show, must stand at the expense of Sphingolahis.
