Vol. xxvii] ENTOMOLOGICAL NEWS. Sits 
Dorsum of thorax black, a pale yellow or yellowish blue ante- 
humeral stripe, expanded above at the antealar sinus, then gradually 
constricted to about one-half the maximum width above, then gradu- 
ally widening till, at its extreme lower end at the end of the sclerite, 
it is about three times its width at the narrowest place above; the 
stripe slightly variable in width in different individuals. A black hu- 
meral stripe, wider than one-half the dorsal black, occupying much of 
the mesepimeron and extended across the mesinfraepisternum, leav- 
ing only the lower posterior border of the latter pale; this humeral 
stripe above notched with pale on its posterior border, and joined along 
the wing base with a more or less distinct short black spur on the first 
lateral suture; sometimes this short spur is joined to the humeral su- 
ture also across the pale notch in the latter, in which case a pale iso- 
lated spot is enclosed. Remainder of sides of thorax pale yellowish 
or greenish, a black spot above on the second lateral suture which is 
usually produced as a narrow, sometimes indistinct, stripe on the 
metepisternum along the second lateral suture, in its maximum de- 
velopment scarcely reaching the level of the mesostigma. A more or 
less distinct broad greenish or bluish band across the metepimeron 
parallel and adjacent to the second lateral suture, the posterior tri- 
angular area thus marked off being more heavily pigmented and more 
distinctly yellow than the area anterior to it. Beneath flesh-colored. 
Abdomen above black, 1 with apical integument blue; black on 2 
more or less narrowed subbasally, at the extreme base expanded later- 
ally as a mere line, widened subapically over an extensive rounded 
area, in general about as wide as the pale sides and as the black on 
I; 3-7 with narrow basal pale rings or spots; 7 apically blue beyond 
the row of spines in every case and in many cases an equal area basal 
to the spines also blue; 8-9 blue; 10 black. Sides of 1 and 2 with 
lower two-thirds greenish, posterior border of 1 black; base of 3 
greenish, fading out posteriorly into yellowish which reaches about 
mid-height, expanded basally to form the basal ring, and constricted 
apically by the expanded dorsal black which, at the extreme apex, 
reaches the lower edge; 4-7 similar but yellowish, with little or no 
bluish or greenish, at the base of each, and with the paler lateral area 
progressively narrowed by the widened dorsal black which reaches a 
maximum on 7; 8-9 blue; 10 black, beneath yellowish brown. Append- 
ages black, inferiors yellowish brown at base. 
Legs yellowish brown, femora black on the superior surface, in- 
creasing apically where the black surrounds the femur, more extensive 
and intense in some individuals than in others but in all darkest on the 
first femora and palest on the last; first tibiae, and second more or 
less, black-lined on anterior face, the line tending to break into a series 
of connected spots; tarsi varying from brown, with apices of joints 
dark, to largely dark; tooth on tarsal claw similar to gracile.
