and extending across the mesinfracpistcrnum ; mesepimeron 

 with a wide black bar on its upper two-thirds, not reaching 

 the wing base; remainder of sclerite a livid purplish of vary- 

 ing intensity, often yellowish above, and always darker below, 

 where it is usually a purplish brown, extended across the 

 mesinfraepisternum; remainder of side of thorax varying 

 from purplish flesh to pale dingy yellow ; metepisternum with 

 a black bar from the stigma up aljout half the distance to the 

 wing base; from the stigma a more or less distinct stippled 

 line runs down between the second and third coxae ; a more 

 or less distinct line above on the metepimeron. Beneath, 

 coxae and wing bases and immediately adjacent areas lemon 

 yellowy the wing bases wnth black markings. 



Abdomen brown or black marked with dingy white or 

 lemon yellow ; segment i yellow, the merest trace of a dorsal 

 median dusky spot, lower posterior border black ; 2 brown or 

 black above, a pale longitudinal median dorsal line ; 3-6 each 

 with a narrow basal pale ring, followed by an extensive dark 

 area, with a more or less distinct pale narrow median longi- 

 tudinal dorsal stripe, which originates in the pale basal ring 

 and is best developed on the proximal segments ; the extensive 

 dark area followed by a reduced pale area, which in turn is 

 followed by an apical black area which is more extensive than 

 the pale area proximal to it, the two apical areas equalling 

 about one-third the length of each segment ; 7 is more or less 

 definitely patterned like 6, but the extensive subbasal black 

 area usually shades out indefinitely posteriorly so the apical 

 pattern is lost, that part of the segment. being like the follow- 

 ing segments; 8-10 dull reddish or yellowish brown, usually 

 progressively darkening posteriorly. Seen from the side. 2

 border dark; 3 similar to dorsal view but the basal and sub-
