(forward) from the mid-dorsal carina, from which it is distant by about 

 its own width. No second pale antehumeral or pale humeral stripe. 

 A pale green stripe about mid- way between the humeral and obsolete 

 first lateral sutures, narrower than the brown areas, which precede or 

 follow it. A green stripe, narrowing upward and interrupted before 

 it reaches the superior metapleural margin, just in front of the second 

 lateral suture. The larger (posterior) part of the metepimeron and 

 all of the pectus greenish-yellow. 



Abdominal segment i greenish-yellow, dorsum brownish; 2 greenish- 

 yellow below, and, including the auricles, brown above, with a narrow 

 median yellow stripe ; 3-10 blackish ; the following yellow : basal fourth 

 and a confluent mid-dorsal stripe, narrowing posteriorly and reaching 

 to the posterior transverse row of denticles of 3 ; basal eighth of 4-6 ; 

 basal two-fifths of 7 ; an indistinct basal mid-dorsal spot on 8 ; inter- 

 articular membrane between 9 and 10. Inferior lateral margins of 8 

 and 9 enlarged, that of 9 strongly convex, the maximum of the en- 

 largement at five-sixth of the segment's length and equal to half of the 

 height of the segment at base ; that of 9 regularly convex and most 

 enlarged at mid-length of the segment. Segment 10 in dorsal view 

 slightly constricted in the middle, its entire and almost straight pos- 

 terior margin a little wider than its anterior; in profile view its hind 

 end longer (higher) than its front end, its lower surface three-fifths 

 as long as its dorsal surface. 



Superior appendages 2.5 mm. long, more than twice as long as 10, 

 longer than 9, subequal to 8, blackish at base, yellow at apex, curved 

 toward each other in the distal third, decreasing in width and thick- 

 ness from base to apex, armed with teeth and spines as follows : a 

 small acute inferior tooth at one-sixth length, a long strong acute in- 

 ferior spine directed downward, caudad, and inward at two-fifths length, 

 a stout rather obtuse superior tooth or tubercle directed upward and 

 inward at two-thirds length ; the extreme acute apex is bent upward 

 almost at right angles, the angle coinciding with the end of an inner 

 thickening of the appendage homologous to the finger-like process of 

 other species. 



Inferior appendage black, divided shortly beyond its base into two 

 slender branches, which are as distant from each other as are the two 

 superior appendages at their bases, each branch curved upward and 

 slightly outward, and reaching caudad as far as the level of the base of 

 the stout inferior spine of the superiors. 



Coxae and femora greenish, tibiae and tarsi black.
