of varying size and, on either side, an orange spot of varying size, 

 in some cases large and conspicuous, and in some cases entirely want- 

 ing; the difference between extreme cases, as in the case of the head 

 markings, is striking; hind lobe largely orange or this reduced to the ex- 

 treme posterior edge and divided in the median line by black. Pro- 

 pleuron black above, yellow below, less variable than the median lobe. 



Thorax above orange or reddish brown ; on either side a straight 

 black stripe, about two-fifths the width of the mesepisternum, sep- 

 arated by a pale median stripe starting at the antealar sinus and 

 widening uniformly below, variable, scarcely more than a line in some 

 cases and, in others, at about its mid length, almost half the width of 

 the adjacent black stripes. A posthumeral stripe, slightly wider than 

 the black stripe on the mesepisternum, entirely black in the brightest 

 colored specimens, in others fading out along its posterior border, the 

 black above and below being most persistent with the intermediate 

 black reduced to the anterior line at some points ; this posthumeral 

 stripe continued across the mesinfraepisternum which is yellow in 

 about its lower half. A black spot on the second lateral suture above, 

 continued below in most cases as a black or brownish stripe lying on 

 the anterior side of the suture, this stripe varying in width from the 

 merest line to about one-half the width of the dorsal black stripe, and, 

 in its extreme length, almost or quite reaching the metastigma. Mete- 

 pisternum pale yellow and dull orange or orange brown in irregular 

 pattern, in some cases the darker color is almost exclusively present, 

 in others it is confined to the median and posterior portions of the 

 sclerite. Metepimeron with a wide stripe of pale yellow parallel to the 

 second lateral suture, the posterior triangular area dull orange. Metin- 

 fraepisternum pale dull yellow, narrowly black above. Beneath pos- 

 terior to coxae dark colored or black, early becoming pruinose, orange 

 brown adjoining the abdomen. 



Abdomen above black, i and 2 usually with purplish reflections, the 

 others with greenish reflections; apical integument of i pale blue; 

 3-8 with small basal, pale blue or green spots or rings ; on 8 these 

 spots are small, bright blue, and widely separated by the median black, 

 not always present or, at least, not evident, in dried material; apical 

 fourth to three-fifths of 8 and all of 9 bright blue, the blue on 8 in- 

 denting the black in the middorsal line in a more or less triangular 

 area, the apex directed anteriorly ; 10 black. Sides of abdomen pale, 

 in the brightest-colored specimens bluish or greenish yellow on I and 

 2, and the base of 3, then yellow on 3-7, 8-10 bright blue ; apical edge 

 of 1-6 narrowly dark or black ringed; pale sides of 2-7 continuous 

 with the basal rings or spots, apically on each segment the dorsal 

 black widens and, with the apical black ring, separates the pale area
