68 Mr. W. F. Kivhj-'N'otes on Foraculidas. 



L. icterica, Serv., bj the second tooth of the forceps being 

 placed, not halfway between the first and the extremity, but 

 close to the extremity ; the female, however, is scarcely 

 distinguishable from that of L. icterica. 



Genus Demogorgon, Kirb. 



De Bormans regards the species of this genus as probably 

 mere varieties of his different subspecies of Labidura riparia ; 

 but they differ in the invariable absence of wing-scales, in the 

 form of the forceps, and in the peculiar sculpture of the abdo- 

 men, and are, to the best of my belief, confined to South 

 America. At present I recognize five species, which may 

 not all be truly distinct : — (1) lividus, Dubr. ; (2) Batesii, 

 Kirb.; (3) hicolor, Kirb.; (4) xanthojms, Stal { = adelj)hus, 

 Kirb.) ; (5) lyatagonliclus, Kirb. 



Genus Anisolabis, Fieb. 

 Anisolahis Duhronii, n. n. 

 A. IcBta, De Borm. (nee Gerst.). 



Gerstaecker's Brachylabis Iceta^ from Kiliraandjaro, has the 

 sides of segments 6 and 7 of the abdomen and nearly the 

 whole of segment 8 above strongly rugose, which is not the 

 case in De Bormans's supposed Anisolabis Iceta from Tenas- 

 serira. 



Genus Sparatta, Serv. 



Sparatta plana, Burm. 



S. apicalis, Kirb., is probably synonymous with this species. 



Sparatta Dohrni^ n. n. 

 Sparatta plana, Dohrn & De Borm. (nee Burm.), 



Genus Ancistrogaster, Stal. 



All cistTog aster luctuosa, Stal, Dohrn. 



A Brazilian insect. Forjicula petropolis, Wood, also from 

 Brazil, comes nearer to the description of this species than 

 to the next, but may be distinct. 



Ancistrogaster Biirrij n. n. 



Ancistrogaster luctuosa, De Bormans. 

 From Mexico and Central America.
