 wider at apex than the base of the first, ovate, fringed with a narrow 

 band of yellowish hairs, and with the apical and lateral part having 

 the appearance of being infuscate owing to the denser black hairs,

 .17". liecuba, which has a similar yellow pubescence on prothorax and 

 scutellum, has the third and fourth abdominal segments banded with
