The genus shows nearest relationship to Mareta,^'' Euthlastohlatta 

 and Dendroblatta,^^ the stouter limbs, however, show rather a devel- 

 opment toward the t\-pe found in Ceratinoptera.^'^ Though dis- 

 tinct, closer affinity with Dendroblatta is indicated. 



The genus is apparently confined in distribution to the south- 

 eastern Ignited States, the Bermudas, Bahamas and West Indies; 

 it includes two species, diaphana (Fabricius) and gemma here 

 described. 



Genotype: Aglaopteryx gemma new species. 



Generic Description. — The sexes show but little differences in 

 size and form. Size medium small, form rather broad, structure 

 very delicate for the group. Head broad, eyes widely separated, 

 face evenly and weakly convex, lateral margins from eyes to bases 

 of jaws decidedly convergent. IMaxillary palpi short for the group, 

 with last joint as long as, to longer than, penultimate joint. Devel- 

 opment of organs of flight of equal degree in both sexes. Teg- 

 mina moderately reduced'*^ or abruptly truncate, ^^ with discoidal 

 sectors, when present, oblique. Wings moderately reduced or 

 absent, when present with venation rather irregular, few costal 

 veins but little enlarged distad and intercalated triangle very small. 

 Dorsal surface of male abdomen not specialized; supra-anal plate 

 very sm.all, transverse, weakly produced; cerci rather short, 

 deplanate abo\-e, with about twelve joints. Cephalic femora 

 rather stout; ventro-cephalic margin of same with or without a 

 few long, stout spines proximad, distad always with a closely set 

 row of minute spines, terminated by two \ery elongate spines. 

 Ventro-caudal margin of cephalic femora unarmed, except for one 

 or two distal spines; ^"entral margins of median and caudal femora 

 supplied with elongate, moderately stout spines. Tarsal joints 

 appreciably more elongate than in Euthlastohlatta, not as decidedly 

 elongate as in Dendroblatta, pulvilli similar in these genera. Dis- 

 tinct but small arolia present.
