it might be I have allowed myself the liberty of giving a detailed 

 account of the species as it is found here: 



C?- Length of body 13 mm., of anterior wings 8 mm. Black, with 

 yellow markings; clypeus, small dot above, sides efface to emargination, 

 large mark above base of antennae, prothorax, tegulae, small dot below, 

 large band slightly interrupted before and after near center first segment, 

 uninterrupted narrow bands on segments 2-5, knees, tibiae and tarsi, all 

 yellow. Head subquadrate, a little broader than high, closely and finely 

 punctate, cheeks and face covered with a fulvous pubescence, which also 

 appears on vertex; eyez emarginate, parallel up to emargination, then 

 inclined inwardly, olive-green; ocelli in a triangle, the foremost larger and 

 set in a cavity ( a groove extending from cavity runs down face almost to 

 base of antennae) nearer to last two than last two are to each other; cly- 

 peus slightly carinate at edge, truncate, sides beyond truncation curved 

 inwardly; mandibles black, mustache slender, fulvous: thorax with a ful- 

 vous pubescence above, posteriorly at sides and below; mesothorax closely 

 and finely punctate, metathorax a little more coarsely but closely punctate, 

 a central groove above and cavity on posterior side punctate throughout; 

 first segment abdomen more coarsely punctate than rest of body, slightly 

 pubescent, but slightly constricted at tip and as wide as second is at base, 

 remaining segments very finely and closely punctate, smooth and shining 

 band on posterior edge of each segment, last two segments immaculate, 

 tip obtuse, slightly emarginate, venter immaculate with a few hairs, 

 smooth. Legs black (except knees and outwards) with a few scattered 

 hairs; stigma and nervures fulvous; wings pale fulvous, first submarginal 

 cell longer than second and third combined, second submarginal receiv- 

 ing recurrent at end of first two-fifths, third submarginal receiving recur- 

 rent near base; submedian cell posterior wings longer than median on 

 externo-medial nervure by more than twice the difference between base 

 of third submarginal of anterior wings and point of receiving the recurrent. 



9- Similar, length of body 16 mm. of anterior wings 9 mm., yellow 

 on face a little more extended, mandibles at base yellow, no yellow dot 

 below tegulae and black, shiny, impunctate bands on abdomen do not 

 appear until second or third segment.
