WYEOMYIA SMITHn 95 



Obiginal Description op Abdks smithii: 



Black, the pleura largely, venter, bases of halteres, coxae, and bases of femora 

 yellow, scales of upper sides of body dark brown, some on the abdomen having a 

 violaceous reflection, scales of the femora black, those on the under side light yellow, 

 scales of bind tibis9 black, those on the inner side and on the front and middle tibiae 

 and their tarsi light yellow, tarsal claws simple; wings hyaline, first submarginal 

 cell nearly twice as long as its petiole; length 3 mm. Two males and three females 

 bred from material received from Prof. J. B. Smith, after whom the species is named. 

 Type No. 5799, U. S. National Museum. 



Habitat. — Lahaway, New Jersey. 



At the suggestion of the writer. Prof. Smith submitted specimens of this species 

 to Mr. Samuel Henshaw, of the Museum of Comp. Zoology at Cambridge, Mass., for 

 comparison with the type of Aedes fuscus, and Mr. Henshaw replied that the two 

 forms are very distinct. The new species will readily be recognized by the absence 

 of cross-bands of yellowish scales at the bases of the abdominal segments. 



Descbdption or Fbmaie, Male, Laeva, and Pupa op Wteomtia smithh: 



Female. — Proboscis moderate, swollen apically ; vestiture black, with a bronzy- 

 blue reflection, brighter bronzy beneath ; labellse small, rounded, with fine out- 

 standing setse. Palpi short, flattened, one sixth as long as the proboscis, bronzy 

 black. Antennae moderate, the joints slender, subequal, rugose, coarsely pilose, 

 black; tori subspherical, with a cup-shaped apical excavation, black, with a 

 whitish pruinosity; hairs of the whorls long, rather sparse, black. Clypeus 

 rounded, convex, black, pruinose. Byes separated at the vertex by a narrow 

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

 reflection, a small silvery spot at the vertex, a white patch below running up a 

 short distance on the eye margin; two long setse at the vertex and a row of 

 shorter ones along margins of eyes. 



Prothoracic lobes elliptical, distinctly separated, clothed with flat violet-blue 

 scales with metallic reflection ; a row of setae on anterior margin. Mesonotum 

 clothed with elliptical, flat dark-brown scales with a pale bronzy reflection; 

 scales below anterior angles yellowish silvery ; bristles over roots of wings black. 

 Scutellum trilobate, with vestiture similar to and continuous with that of the 

 mesonotum, each lobe with a small tuft of black bristles. Postnotum elliptical, 

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

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



Abdomen subcylindrical, compressed, truncate apically and with many coarse, 

 long, dark-brown terminal setae ; dorsal vestiture black with a strong bronzy and 

 blue reflection ; venter silvery white, colors separated at sides in a straight line. 



Wings moderate, hyaline; petiole of second marginal cell one-third as long 

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

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

 ligulate, black, with bronzy reflection on eosta, broader and denser on forks of 

 second and fourth veins and outwardly on third vein. Halteres whitish with 

 black knobs. 



Legs moderately long and slender ; vestiture black with bronzy and blue reflec- 

 tion, all the legs pale bronzy beneath throughout, the femora whitish towards 

 base ; mid tarsi with the apical portion of the second joint and all of the third 

 and fourth joints white on the outer side. Claw formula, 0.0-0.0-0.0. 



Male. — Proboscis as in the female, the pale shade beneath becoming silvery 

 towards the base ; antennae similar to those of the female, the hairs of the whorls 

 longer and more abundant. Coloration as in the female. Tip of abdomen 

 expanded, with numerous coarse bristles ; ventrally the scales are raised along 

 the median line. Wings slightly narrower than in the female, the venation and 

 vestiture about the same. Middle legs slightly shorter than the anterior ones, 

 the last tarsal joint armed with a single, large, simple claw; femora nearly 

 silvery white beneath; tibiae and tarsi with a brilliant, pale-brassy luster be-
