the lateral margins. Abdominal pile entirely black ex-

front entirely light reddish chestnut brown divided down 
the middle with faint linear impressions. The pile of 
the eyes is more sparse but is of the same color as in the 
male. Third antennal segment slightly concave in the

Male. Head : the face, cheeks and front are light yel-

light brownish to reddish yellow and quite thick upon the 
upper half. Thorax: mesonotum with opalescent strong 
greenish reflections and a coppery reflection where the
