$ Head black with a metallic violet reflection ; a pale 

 postocular spot, some marks along the hind margins of 

 the eyes and the labrum obscure yellowish. Eyes brown 

 above. Dorsum of thorax to first lateral suture very 

 dark metallic violet, mid-dorsal carina black, a narrow 

 yellowish-brown stripe, but veiy little antehumeral in 

 position (almost obliterated in dry specimens) ; sides pale 

 brownish, a black line on second lateral suture. Feet 

 dark brown, third femora with a superior yellowish streak. 

 Abdomen black, a narrow transverse basal blue ring on 

 3-7; 9 with an apical lilac (?) spot, variously trilobed 

 anteriorly, or its apical half with a median, and a lateral 

 lilac (?) spot each side. Superior appendages half as 

 long as 10, dark brown, excavated below, apical third 

 bifid, upper-outer branch larger, longer;* lower-inner 

 branch pointed. Inferior appendages pale, longer, apex 

 bilobed, apices of both lobes rounded, the lower-inner 

 lobe the more slender, the upper-outer lobe with a black 

 spot. 



? Similar to the 3 , black replacing metallic violet, pale 

 colors blue ; a transverse blue stripe across the frons 

 anteriorly; antehumeral stripe wider: a superior spot or 

 a short superior stripe, pale colored, on the humeral 

 suture ; a black superior spot or complete stripe on the 

 second lateral suture. Feet blue, an anterior and a supe- 

 rior femoral stripe, tibial anteriorly, and the tarsi black. 

 Abdominal dorsum black, 3-7 with a transverse interrupted 

 basal blue ring; 8 sometimes with a mid-dorsal, longitud- 

 inal, blue stripe dividing the black; 9 blue or green with 

 a black spot each side at base ; 8-9 with an inferior, 

 lateral, longitudinal, brown stripe; 10 blue, cleft dorsally 



*Fig. 12, pi. XV, apparently shows the reverse, as the enlargement of 

 the upper-outer branch is mainly horizontal.
