Unfortunately, I identified this species recently (Webster, I.e.) as a 

 new genus and species, giving it the MS. name Pediobioidea cya?iea^ 

 However, the mistake was discovered before publication of the descrip' 

 tion, so that the name is a iiomen nudum. The species is poorly described, 

 so that I redescribe it herewith and designate a type from the original 

 specimen. 



Normal position. Male. — Head triangular (cephalic aspect), 

 slightly wider than long and wider than the thorax, the face 

 reticulated, impressed along each side of the meson (the scrobes), 

 the malar space large, smooth. Eyes oval, on the lateral aspect ; 

 ocelli in a triangle on the vertex, the lateral ones about their width 

 from the eye-margin and near to the rounded or obtuse occipital 

 margin ; head (dorsal aspect) about 2}^ times wider than long ; 

 antennae inserted below the middle of the face, but above (dorsad) of an 

 imaginary line drawn between the ventral ends of the eyes, rather short, 

 in both sexes 8 jointed, with a ring-joint, the club single and acuminate at 

 extremity, the funicle 4-jointed, the apical three joints moniliform, and the 

 fiagellum (excluding pedicel) clothed with rather long, soft, dense, whitish 

 hairs. Head, pronotum and dorsum of the mesothorax delicately, 

 squamosely reticulated, the metathorax glabrous and prolonged caudad 

 into a short truncate neck (dorsal, lateral aspects) ; metathoracic spiracle 

 minute, margined and oval. Abdomen distinctly petiolate, smooth, oval, 

 the second segment occupying most of the dorsal surface, the others
