A local race of Deinocerites cancer Theobald, differing by its very ,, 

 dark, almost black color ; the clypeus and tori, which in the type forml 

 are yellow or yellowish brown, are here dark brown ; the mesonotum 

 is pitchy brown, the scales black with brownish luster, the metanotum 

 is pitchy brown, nearly black ; the abdomen is black-scaled above and 

 beneath ; in the male with blue and green iridescence. The legs are 

 black. 



Nine specimens. Colon, Canal Zone, Panama (August Busck, col- 

 lector), from larvae in crab-holes near the ocean. 



Type. —No. 10865, U. S. National Museum. 



Uranotaenia calosomata, new species. 



Proboscis moderately long and slender, slightly enlarged apically ; clypeus and 

 tori dull brown ; occiput brown scaled with two oblique lines of white scales, which 

 converge upon the vertex and terminate in a white tuft ; thorax deep brown, on the 

 lateral margin a line of white scales to the base of the wing ; pleura brown with a 

 longitudinal stripe of white scales extending forward over the prothoracic lobe and 

 joining the stripe on the head ; metanotum brown. Abdomen black scaled at the sides, 

 above clothed with ochreous yellow dull metallic scales, leaving a narrow black line 

 at the base of each segment, becoming broader on the terminal segments, and a sub- 

 basal median black spot ; beneath with black vestiture and apical white bands, which 

 are broadest on the centers of the segments. Legs black with bronzy and brassy 

 luster, the apices of the femora white ; on the hind legs the dilated apices of the 

 tibiae have a patch of white scales ; hind tarsi with the third, fourth and fifth joints 

 white with metallic luster. Wings heavily dark-brown scaled on the costa, the basal 

 third of the first vein white scaled, the two forked cells small but broad, the second 

 posterior cell slightly longer than the second marginal cell. Length, 2.5 mm. 



Five specimens, Tabernilla, Canal Zone, Panama (August Busck, 

 collector), bred from larvae in prints of horses' feet containing water. 

 Type. — No. 10866, U. S. National Museum. 



Uranotaenia typhlosomata, new species. 



$. — Proboscis long and slender, much swollen at the apex, black scaled; 

 antenna; amply plumose ; palpi very short, black scaled ; occiput black scaled, the

 dark-brown scales ; scutellum with metallic-blue scales, the setae long, black ; in 

 front of the roots of the wings is a short stripe of silvery-blue scales and a similar blue 

 stripe extending over the anterior half of the pleura and over the prothoracic lobes ; 

 metanotum dark brown ; abdomen depressed, black scaled above and at the sides ; 

 legs black with bronzy luster, the knees with a minute silvery spot and at the apices 

 of the hind tibiae another ;,on the hind tarsi the apical three fifths of the third and all 

 of the fourth and fifth joints silvery white ; wings black scaled along the costa, 

 brown scaled on the veins, the base of the first vein with a patch of silvery scales, 

 the fifth vein with a line of silvery scales close to the base. Length, 2 mm.
