Desceiption of Female, Male, and Labva or Aedeomyia squamipennis : 



Female. — Proboscis rather short, uniform, upcurved; vestiture of blackish 

 scales, a broad white ring before middle and another one at apex involving 

 labellae, at the base a dorsal patch of yellow scales. Palpi short, about one-fourth 

 the length of proboscis, rather stout; vestiture of coarse roughened scales, mostly 

 black, the apical ones white, at the middle a band of yellow scales and a sprin- 

 kling of yellow scales on the basal portion. Antenna short and rather stout; 

 segments short and thick, narrowed basally, deep brown, with a white basal 

 ring; pubescence abundant, silljy white; second segment apieally enlarged, 

 densely clothed with broad, coarse, suberect, yellow scales; hairs of whorls 

 short and rather sparse, black ; tori rather small, globose, yellow-brown, clothed 

 with broad yellowish-white scales. Clypeus large and prominent, conical, light 

 brown, clothed with broad suberect yellow-white scales. Eyes separated by a 

 crest of yellowish-white scales. Occiput covered with a dense mass of yellowish- 

 white and black semi-erect broadly ovate scales and on the nape with a dense 

 mass of partly black and partly dull whitish, broadly triangular, erect scales, 

 their broad apical margins finely serrate ; the black erect scales massed at back of 

 head and large sublateral patches of ovate black scales close to ocular margins ; 

 a quadrate white patch at vertex; sides of head behind eyes spotted black and 

 white ; bristles along margins of eyes fine, moderately long. 



Prothoracic lobes lateral, luteous brown, clothed with dull white scales and 

 with many coarse black bristles. Mesonotum dark brown, densely clothed with 

 small broadly ovate scales, on disk with ocher-yellow scales, becoming whitish 

 on anterior edge; lateral margins blackish-brown scaled, narrowly in front, 

 broadly along posterior two-thirds; on basal third two broad ill-defined sub- 

 median black stripes which become confluent with the lateral margins over roots 

 of wings ; basally there are also indications of a short submarginal white stripe ; 

 setse of mesonotum rather abundant, moderately coarse and not long. Scu- 

 tellum clothed with broad yellowish-white scales, a narrow line of black scales 

 on median lobe, the lateral lobes with apical patches of raised black scales; 

 setse in three groups, rather coarse and moderately long. Postnotum promi- 

 nent, the median ridge faintly indicated, luteous, dark at sides, nude. Pleurae 

 and coxaa luteous-brown with blackish spots, clothed with ovate white scales. 



Abdomen subcylindrical, somewhat depressed, compressed towards apex, 

 eighth segment subtruncate; eerci slender; dorsal vestiture of broadly ovate 

 dull brown scales, with oblique, lateral, segmental, ill-defined dirty-white stripes 

 which reach margins at hind angles ; the whitish scales predominate on seventh 

 and eighth segments and these bear a median patch of brilliant white scales at 

 hind margins; first segment dark scaled and with many fine pale hairs ; ventral 

 vestiture a mixture of white and black scales, the white scales predominating 

 at bases and apices of segments. 



Wings short and broad, hyaline ; vestiture along the veins so dense that very 

 little of the wing-surface remains exposed, the fringe very long; veins on 

 anterior part of wing well separated, so that the fourth vein crosses the wing 

 slightly behind the middle; second marginal cell very long, about one-third 

 the entire length of wing; base of second posterior cell nearer base of wing 

 than base of second marginal cell; basal cross- vein slightly more than its own 

 length from anterior cross-vein; vestiture predominatingly of dusky-brown 

 scales with a mixture of white and ocher-yellow ones, the yellow scales showing 

 a tendency to group in patches and densest on apical portion, basal third, and 

 along the margins ; the white scales form two slender irregular and wavy trans-
