 essentials: 



Gcrial plates (plate T. D) at tlieir inner cephalic aimle evenly 

 rdimded. not jiroiliiced into a prominent lolie. The hihrum 

 (plate T, r.) is much more produced, conical. Iieai-ini;- a little 

 tuft of hairs at the tip a.nd a small, cylindrical, chitinized 

 tuliercle on either side of tlie tip; the lateral lohes are very 

 prominent, cylindrical, densely clothed with lon<>' short hairs, 

 tlie Idhes heiit jjroniinently inward. Aiitouur (plate I, C, a) 

 niore cluh-shaped, the distal end being larg-er than the base; 

 hairs at the apex short. Mandibles (plate I, G) with a promi- 

 nent conical tooth at mid-length, this tooth squarely trnncated 

 at apex and hearing a smaller tooth at its side. Size of the 

 head-capsule, 2.7 by 1.2 mm., across the genal plates. 



Stigmal field (plate I, J) with the spiracles ronnded-oval to 

 rounded, j^laced obliquely, very widely separated from one 

 another. Four conspicuous lohes surrounding the stigiual iield, 

 (if which one pair are lateral and the other ventral. Each 

 lateral lobe slender, with a narrow straight black mark on its 

 iimei- face, at its inner end, this mark scarcely if at all enlarged; 

 the lobe bears a dense fringe of long, delicate, pale brown hairs 

 along its dorsal face, these liairs quite inconspicuous due to their 

 pale cojoi-. l']ach venti-al lolie very long and slender, the inner 

 face witli a narrow, straight lilack line which is expanded out 

 at the base into a dark brown triangular mark which meets its 

 fellow of the o])posite side on the median line, the two enclosing 

 a ])ale, oval area l)etween them; a fringe of rather long pale 

 hairs on the apical third of this lobe. A pale lirown mark runs 

 from eacli stigma dorsad. Stigmal field almost destitute of 

 dark spots or marks.
