Gnathos typically paired, directed ventrocaudad, lateral margins 

 very heavily sclerotized; arms subparallel, approximate, weakly scobin- 

 ate entad, with apices narrowly but evenly rounded. 



Anellus rather large, ventral portion membranous and unarmed ; juxta 

 absent but dorsal portion noticeably thickened and darkened by in- 

 creased sclerotization, with distinct longitudinal ridges, and concave 

 beneath. 



Aedeagus rather elongate and slender, approximately five-sixths as 

 long as harpe, cylindrical, asymmetrical, sublinear in dorsal and ventral 

 aspect, small basal portion and approximate apical two-fifths curving 

 markedly ventrad in lateral aspect, base moderately expanded ventrad, 

 central portion commonly armed ventrolaterad with scattering of 

 minute spinelike processes, approximate apical third gradually and 

 increasingly opening dextrad toward apex, apical quarter slightly 

 expanded, apex very narrowly but evenly rounded 



Vesica of medium size, bulbous, membranous, unarmed.

Remarks. — This old species, although widely distributed, is appar- 

 ently only locally common. Its considerable variation in size and 

 color pattern undoubtedly accounts for its two synonyms. The 

 material representing texanellus was received on loan from ten sources, 

 with Cornell University furnishing about one-third of the specimens in 

 a series of 11 cf cf and 4 99. 



A. texanellus is related to those acrolophids having elongated labial 

 palpi and setose eyes, from which species it may be separated by its 

 distinctive unipectinate antennae, each segment of which is completely
