width of the capitulum, but in some of the other characters 

 mentioned by Pilsbry it seems to be quite distinct. 'The 

 basal width of the capitulum is relatively greater, the basal 

 margin of the scutum appears to be at right angles to the 

 chord of the occludent margin, the carina is straighter, and 

 the width of its upper part is about one-sixth of its length. 

 No details are given as to the appendages.

$ . Ferruginea ; vertice fascia transversa nigra ; valvulis terebrae 

 nigris, tertio apicali flavidulis ; alis hyalinis, venis fuscis, stig- 

 mate ferrugineo. 



Long. 14-16 mm. ; terebraa long. 6 mm. 



c? . Feminae similis, vertice fronteque nigris. 



Long. 16-17 mm. 



¥ . Head fairly large, broader than the thorax; the poste- 

 rior margin distinctly raised and broadly emarginate, sepa- 

 rated from the eyes by a distance equal to about one-third of 

 their length. Vertex and front coarsely punctured-rugose; 

 the face below the antennae less coarsely punctured-rugose, 

 punctured in the middle ; a triangular tubercle between the 

 antennas. Clypeus somewhat shining, microscopically punc- 

 tured, with sparse larger punctures intermingled, the apical 

 margin almost straight. Second joint of the flagellum a 

 little longer than the third, more than four times as long as 

 the first ; posterior ocelli separated from each other by a 

 distance equal to two-thiids of the length of the second joint 

 of the flagellum, a little nearer to the eyes than to each other. 

 Neck short ; pronotum not produced at the angles ; thorax 

 coarsely rugose; the mesonotum distinctly margined both 

 anteriorly and laterally, the anterior margin straight ; pleurae 

 less coarsely rugose ; median segment rugose-reticulate
