 the body, rather stout, and slightly enlarged towards the apex. Clypeus prominent, 

 luteous brown, with a row of fine hairs along each side, none in front nor on the

 boscis ; tori yellow-brown ; antennae with whorls of long hairs ; occiput clothed with 

 flat irridescent blue and green scales, brilliant silvery in some lights ; hind margin 

 with a row of erect dark scales ; prothoracic lobes large and prominent, well sepa- 

 rated, clothed with brilliant silvery scales ; mesothorax somewhat compressed, clothed 

 with dusky scales, pleura ochreous yellow, with patches of silvery scales ; scutellum 

 clothed with broad flat metallic blue-green scales ; metanotum with three longitudinal 

 impressions, a group of coarse terminal hairs ; abdomen obliquely truncate at the tip, 

 clothed above with dusky scales, which show raetallic-green and steel-blue reflec- 

 tions ; beneath silvery white, encroaching on the lateral area as rounded segmentary 

 incisions. Wings long and narrow, hyaline, the scales of the veins dusky. Legs 

 long, slender, without raised scales, black, with metallic violet and blue reflections, 

 the tarsi of the middle legs with the last four joints brilliant white, the hind legs 

 with the outer half of the third and the last two joints white. Claws simple.

$ . — Proboscis shorter than in the female, more distinctly swollen at the tip ; 

 palpi long, nearly as long as the proboscis, very slender; antennae rather sparsely 

 plumose ; abdomen much compressed ; claspers stout, rather small ; no lateral fringe. 

 Length, 5-5 nim. 



Thirty-six specimens, Tabernilla, Canal Zone, Panama (August 

 Busck, collector), bred from larvse in bamboo joints. The larva re- 

 sembles that oi Joblotia digitatus Rondani, but has the mandibles long 

 and slender. In some of the adults there is a little of black on the 

 last joint of the middle legs.
