kennedii, except in younger individuals which are as blue as "gracile." 

 Posterior triangular portion of the metepimeron heavily pigmented 

 yellow except in younger individuals where it is blue, similar to adja- 

 cent areas. In Trinidad specimens of ascendens the humeral stripe is 

 often less intense black than the dorsal stripe, tending to a reddish 

 tinge; rarely the humeral stripe is entirely dark reddish brown, the 

 margins, especially the posterior, not sharply defined and with black 

 confined to the extreme upper end and a trace, if any, near the mesin- 

 fraepisternum. Such differences are not due solely to age; a pruinose 

 male from St. Ann River, Trinidad, is the palest individual I have 

 seen; in this specimen, head, prothorax, thorax, abdomen and legs all 

 have the black reduced, not as readily noticed in the case of the abdo- 

 men ; the legs are especially pale, the last legs with only a trace of 

 color near the apex of the femora, the first femora with a little more 

 than the apical half of the anterior dorsal surface dark, and the mid- 

 dle legs intermediate in color. 



Abdomen similar to kennedii, but the dorsal black on i is narrower 

 than on 2, and greatly constricted subapically to a varying extent, 

 rarely reduced to a line, but usually this apical black is a stripe about 

 one-third as wide as the basal black area anterior to it. Segment 7 

 black to apex with integument brown, or apex with a large semicircular 

 blue spot which, in the midline, reaches anterior to the apical row of 

 spines a distance equal to three to five times the length of the integu- 

 ment posterior to the row of spines. In brightly colored specimens 

 the pale colors on the first six segments are all yellow or yellowish, 

 blue first appearing on the basal ring of 7, which segment, like the 

 preceding segments, has the sides below yellow ; in duller specimens 

 the basal rings on 4-6 are obscurely colored. Sides similar to kennedii, 

 with blue more extensive on i (see description above of dorsal view) ; 

 segments 8 and 9 blue, unmarked except for a shining black spot in the 

 apical integument just below midheight, conspicuous only by reason of 

 the clear blue surrounding it, or the entire lower border of 8 and 9 

 may be black, except the base of 8, this black broadest on 9 and, on 

 both segments, produced dorsally in the apical integument to join the 

 shining black spot described above ; between these two extremes all 

 intermediate stages exist; 10 black, dull orange or reddish brown be- 

 neath, in one Georgetown specimen a small round median blue spot 

 on the side. Superior appendages black or dark brown; inferior ap- 

 pendages dull orange or reddish brown, darker at apex. 



Legs light brown or cream-colored, paler than in kennedii and with 

 more restricted dark markings ; the first femora the darkest, the last 

 the palest, dark markings confined to the dorsal surface of the femora, 

 darkest apically, and greatly reduced or almost wanting on the last 

 femora, some of the Trinidad specimens the palest of the series.
