lovvish brown, and with three rather large whitish grey triangles on 

 the abdominal segments, as well as with five rather broad grey stripes 

 on the thorax. 



Female. Head broader than the thorax, and less than half the 

 length of the thorax, moderately arched. Frontal stripe broad, con- 

 tracting from the vertex to the eye-angles, and about four and a seven- 

 tenth times as long as its narrowest part or about three and a two-fifth 

 times as long as its broadest part, covered with pale yellowish tomen- 

 tum which becomes more whitish above, and clothed with numerous 

 short sloping blackish brown pubescence which becomes irregularity 

 suberect about the middle, and at the sides there are some pale 

 yellowish white hairs which grow up numerous and more conspicuous 

 down to the callus proper ; the surface of the frontal stripe very 

 inconspicuously elevated from the eye-level, with two rather distinct 

 but fine oblique depressed stripes, of which each extends from just 

 below the vertex to below the middle of the eye-margin but not united 

 with one another at the upper end, the space between these two stripes 

 being dark brown when seen from in the front owing to the numerous 

 irregularity directed blackish brown pubescence ; vertex rather well- 

 defined, covered with somewhat longer blackish brown pubescence and 

 without any trace of the ocelligerous tubercle ; frontal calius rather 

 large and moderately convex, reddish brown but darker brown at the 

 upper extension which is rather broad but still linear and pointed and 

 is a little longer than the lower broad part where it is oblong 

 gradually narrowed above, and about twice as long as its widest part, 

 this callus distinctly separated from the eye-margins by the narrow 

 yellowish grey dusted intervals but touching the frontal triangle; front- 

 al triangle clothed with pale yellowish grey tomentum which becomes 

 more yellowish on the double crescent just above the antennal fossae, 

 slightly elevated, apparently broader than the length, with a fine but 

 conspicuous median sulcus and with two broader but not well-defined 

 oblique furrows situated near the eye-margin and parallel with the
