102 MOSQUITOES OF NORTH AMERICA 



Obiginal Descbiption of Wyeomtia codiocampa: 



5- — Proboscis rather short and stout, thickened towards the apex, black scaled; 

 clypeus large, globose, brown with minute gray pubescence; palpi very short, black 

 scaled; eyes divided by a narrow white-scaled strip; occiput clothed with brownish 

 iridescent scales, the ocular margin narrowly white and forming a triangular patch 

 between the eyes; prothoracic lobes large, prominent, well separated, the basal por- 

 tion silvery white, tip also white, the central portion blackish brown; mesonotum 

 short, convex, clothed with bronzy brown scales; setae of the scutellum ferruginous 

 yellow; metanotum pitchy black with a group of setae towards the apex; abdomen 

 rather stout, compressed, truncate at the tip with numerous terminal coarse bristles, 

 black scaled above, creamy white beneath, the white forming deep lateral incisions 

 at the apices of the segments; legs dark, with bronzy luster, the fore legs pale 

 brassy beneath throughout their length, mid legs with the apical portion of the 

 second, the third and fourth joints silvery white beneath, hind legs with the second 

 and third joints silvery white beneath, the- fourth and fifth bronzy brown. Length, 

 4 mm. 



S- — Antennae shorter than in the female, the hairs of the whorls more numerous; 

 palpi very short, white scaled; abdomen strongly compressed along the anterior two- 

 thirds, the apex dilated, with lateral and ventral groups of coarse bristles; front legs 

 with the third and fourth joints silvery white beneath, the middle and hind legs 

 light brassy beneath, on the mid legs becoming silvery white on the third and fourth 

 joints, on the hind legs the apical half of the first, the second, third and basal part 

 of the fourth joints silvery white beneath. Length, 4.5 mm. 



Eleven specimens, Tabernilla, Canal Zone, Panama (August Busck, collector), part 

 of the specimens bred from larvae in bamboo joints, the others caught In a bamboo 

 woods.

Descbiption of Female, Male, and Lasva of Wyeomtia codiocampa: 



Female. — Proboscis rather short and stout, enlarged apically, labellse small, 

 rounded, with fine outstanding setae ; vestiture bronzy black. Palpi short, flat- 

 tened, one-sixth as long as proboscis, bronzy black. Antennae moderate, the 

 joints slender, subequal, rugose, coarsely pilose, black; tori subspherical, with 

 a cup-shaped apical excavation, luteous brown, with a silvery-white pruinosity; 

 hairs of whorls long, rather sparse, black. Clypeus broadly rounded, convex, 

 dark brown, pruinose. Eyes separated at the vertex by a narrow wedge, 

 bluish black. Occiput clothed with flat brown scales with a metallic reflection, 

 a small white spot at the vertex and a narrow border along the lower half of the 

 eye, widening to a patch below; two long setae at the vertex and short ones 

 along the margin of the eyes. 



I*rothoracic lobes elliptical, distinctly separated, clothed with flat scales, brown 

 in the middle, silvery white at tip and base; a row of setae along anterior 

 margin. Mesonotum clothed with elliptical, flat brown scales, with bronzy 

 and blue reflection ; scales on anterior margin and below lateral angles whitish ; 

 bristles over roots of wings brown. Scutellum trilobate, with the vestiture 

 similar to and continuous with that of the mesonotum, each lobe with a small 

 tuft of black bristles. Postnotum elliptical, prominent, with a low, broad 

 median carina, dark brown, a group of small setae near posterior margin. Pleurae 

 dark brown, the coxae luteous, clothed with elliptical, flat silvery-white scales. 



Abdomen subcyUndrical, strongly compressed, truncate at tip, with many 

 long, dark-brown terminal setae; dorsal vestiture black, with a slight metallic 

 reflection ; venter yellowish white, the color continued on the sides as triangular 

 lateral patches along the posterior margins of the segments ; the scales raised 

 along the mid- ventral line. 



Wings moderate, hyaline; petiole of second marginal cell less than one-half 

 as long as its cell ; that of second posterior cell shorter than its cell ; basal cross- 

 vein distant less than its own length from anterior cross-vein ; scales of veins 

 small, appressed, narrowly triangular, black, with bronzy reflection on the 

 costa, broader and denser on second to fourth vein apically. Halteres whitish 

 with black knobs.
