 length of the head, ochraceous ; palpi and antennse dark brown, 

 the basal joints of the latter tinged with ochraceous, the flagellar 

 joints gradually diminishing in size, large and globose at the base, 

 becoming slender and oblong towards the tip. Thorax brownish- 

 ochraceous, shining, with three deep brown or black stripes ; 

 intermediate one beginning at collare ; lateral ones much broadened 

 anteriorly, completely interrupted at transverse suture, with a 

 yellow spot at their posteriorly extremity above the origin of the

 almost straight to the margin, the sixth longitudinal vein is a little 

 sinuated at the tip, and that of the seventh considerably arcuated.
