PROSTEMMIULUS NESIDES, new species. 



Plate 1, figs. 1-3. 



Blackish excepting head and first four tergites, which are of a 

 chestnut cast. A median dorsal pale line. Lower part of sides and 

 the venter paler, more brownisli. Legs dusky flavous. Antennae 

 black. 



Head with the usual two oceli on each side of which the inferior 

 one is minute in comparison with the upper one. Antennae slender; 

 sixth article clavate, about twice as long as thick at distal end. 



Collum with one deeper sulcus margining it in front and continu- 

 ing back to caudal margin; below it and on the inflexed portion of 

 the plate are three finer striae parallel with it, these not visible in 

 lateral view. 



Second tergite striate only beneath. Striae on succeeding tergites 

 rising progressively higher and first reaching middorsal region on 

 the ninth segment. Setiferous papillae of last tergite as usual. 



Sternites of tenth segment as shown in plate 1, figures 2 and 3. 



Length. — 14.5 mm. ; width, 1.3 mm. 



Locality. — Isla de Pinos: Bibijagua. One female (Barbour and 

 Brooks, June, 1918). 



Type.— Cd^t. No. 5030, M. C. Z. 



EPINANNOLENOIDEA, new suborder. 



Includes the Epinannolenidae, new family, and the Pseudonan- 

 nolenidae. 



EPINANNOLENIDAE, new family. 



The genus Ephumnolene has heretofore been included in a family 

 Nannolenidae on the assumption of a close relationship to Nannolene. 

 However, an examination of the copulatory organs of the male of 

 Nannolene hurkel Bollman, the genotype, shows this genus clearly 

 to be a cambaloid form close to Dimerogonvs of Attems and related 

 genera having flagella on the anterior gonopods (pi. 1, figs. 4-10). 

 Thus the name Nannolenidae falls as a synonym of Cambalidae or 

 Cambalinae in the strict sense, for which Attems proposed Mastigo- 

 cambalinae, a name untenable both because not based upon an in- 

 cluded genus and also because it includes the type genus of the 

 family which must accordingly be the basis of the name. Attems's 

 name Glyphiocambalinae for the subbranch including genera not hav- 

 ing flagella on the anterior gonopods is also not tenable because not 

 based upon an included genus. It may be replaced by Glyphiulinae, 

 new name. 



For Epinannolene a new family name must be given; and Epinan- 

 nolenidae is accordingly here proposed.
