Jn specimens of group 2 the colors are as follows : face 

 markings dark brown, conspicuous and well defined ; pale dor- 

 sal thoracic stripes very slightly narrower than in group i, 

 widely separated from the pale mesothoracic collar, which is 

 more w-idely divided in the median line than it is in group i ; 

 pale antehumeral narrowly to widely separated above to form 

 a superior spot and an inferior stripe ; pale stripe on mese- 

 pimeron narrower than in group i, and separated to form a 

 superior and inferior spot; pale stripe on metepisternum nar-

 form a superior spot and an inferior stripe ; metepimeron large-

 segment i narrowly pale below on the sides ; 2 with a median 

 dorsal spot, the auricle, and the inferior posterior margin of 

 the segment narrowly pale ; 3 with a narrow dorsal stripe from 

 the base to three-fourths the length of the segment, and with 

 the inferior lateral margin very narrowly pale ; on 4-6 the pale 

 area is restricted to a small dorsal basal spot on each seg-
