 (Type in my collection.) 



'Ihis is an aberrant form, Avhich I have ranged in Lahia 

 on account of its cylindrical second tarsal segment ; the 

 form of the forceps is curious, and rather recalls that of 

 some Anechura or Ghelidura. 



Platylalia gcstroi, Bormans. 



The Paris collection contains a female from Diego 

 Suarez (Alluaud, 4-96), that I consider to be of this 

 species ; it is recorded from Fly River, New Guinea, and 

 only the male lias been described, the so-called female 

 of Dubrony (Ann. Mus. Civ. Gen., xiv, 1879, p. 372) 

 being the nymph. 



If this is the true female, it hardly differs from the 

 male ; the pygidium has the same shape, but the branches 

 of the forceps are simpler, not being dilated nor depressed 

 on the inner margin. The colour is very dark, but the 

 members of this genus and the allied genera Sparatta and 

 Chmtosimnia often darken after death.
