about two and one-fourth times its length, its length a little 

 more than four times that of the vertex, the hind margin slightly 

 incurved; surface thickly, evenly shagreened. Scutellum longer 

 than head and thorax together ; basal field, except lateral margin, 

 shagreened; apical field, except calloused lateral margins, trans- 

 versely wrinkled, as are also the submargins of basal field; 

 transverse impressed line strongly, angularly bent, open at apex 

 of angle, the lateral limbs arcuate, the space between them 

 transversely wrinkled. Last ventral segment of female very 

 short, its hind margin subtruncate to slightly sinuate. Hind

This variety differs from var. philippinensis as follows: Dis- 

 tance between ocelli one half of width of front ; clypeus somewhat 

 shorter and broader; lorse longer than clypeus, but not twice 

 its breadth at middle; scutellum with transverse impressed line 

 very obtuse-angularly bent, the lateral limbs scarcely arcuate. 

 Hind margin of anal segment of female more strongly sinuate, 

 medially strongly notched.

This variety differs from var. philippinensis as follows : Length 



' of vertex at middle into width between eyes less than six times ; 



distance between ocelli about half the width of front; lorae less 



than twice the width of clypeus ; hind margin of anal segment of 



female truncate.
