with which they are often intimately associated. A mass of congregated pupae 

 will frequently contain individuals of both species in about equal number and 

 the pupae of Myzomyia are only distinguishable by their lighter color and slightly 

 smaller size.

Description of adult female 4 ( PI. V, fig. 1 ) . — Palpi deep brown, the apex broadly 

 white-banded, another small band close to it and a third much lower down (PI. 

 VII, fig. 2) ; proboscis deep brown, with distinct, creamy-white tip. Thorax fawn- 

 colored in the middle, dark brown at the sides, with a median and lateral dark 

 lines and curved, hair-like, pale scales ; abdomen brown, with pale hairs. Legs 

 mottled and spotted with yellow; tarsi apically and basally pale, banded. Wings 

 with 4 large costal spots and one or two small basal ones, most of the veins of 

 wing area pale scaled. (PI. VII, fig. 3.) 



5 Head pale brown, with narrow, pale scales and pale and brown, upright, 

 forked ones, a pale, median tuft projecting forwards; antennae brown, basal joint 

 pale ferruginous: proboscis deep brown, apex creamy, palpi deep brown, with 

 a broad, creamy, apical band, and near it another narrow, pale band, the re- 

 mainder divided by another narrow, pale band, base densely dark scaled. 



Thorax fawn-colored in the middle, dark brown at the sides, with a median, 

 dark line and a narrow, dark line on each side of the pale area, with scanty, 

 hair-like, curved, pale scales and traces of a dark spot before the scutellum, which 

 is pale brown, with narrow hair-like scales; pleurae brown, mottled with gray. 



Abdomen brown, with narrow, curved, hair-like scales and pale posterior 

 border-bristles. 



Legs brown, the femora and tibiae and metatarsi, especially in the hind legs, 

 spotted with yellow : tarsi with broad, apical and basal, pale banding, especially 

 on the hind legs; ungues small, equal and simple. 



Wings with 4 large, dark, costal spots and two small,' basal ones, the apical 

 spot small, extending evenly on to the first long vein : this is followed by a pale 

 area nearly twice as long as the black apical spot. The second black spot is 

 about the same length as the preceding pale one, and spreads evenly on to the 

 first long vein; the next pale area is slightly longer. The third black spot is the 

 largest and spreads nearly evenly on to the subcostal vein, while beneath it on 

 the first longitudinal is a large, black line and then a small, pale area followed 

 by a small, black spot, the black line not beginning directly under the costal spot. 

 The fourth black spot is separated from the third by a very small, pale area, 

 and extends evenly on to the subcostal and first longitudinal ; at the base is 

 another small, black spot. The second long vein has dark scales on each side 

 of the cross-vein and a dark spot on the upper, branch of the fork-cell under 

 the apical costal spot, and another small one near its base; the lower branch has 

 an apical spot and a larger one near its base. The third long vein has a black, 

 apical spot and a dark patch on each side of the cross-veins; the fourth is mainly 

 dark on each side of the cross-veins, and has 2 dark spots on the upper branch, 

 one near the base and two on the lower branch; the fifth has a black spot at its 

 root, 3 on the upper branch and one at the apex of the lower branch; the sixth 

 has 2 dark spots. The first submarginal cell is a little longer and decidedly 

 narrower than the second posterior cell, its base slightly nearer the apex of the 

 wing than that of the second posterior cell, its stem as long as the cell; stem of 

 the second posterior considerably longer than the cell; supernumerary and mid

 Mono. Culic. (1903). 3, 42, while that of the male is prepared by myself, this 

 sex having never been described.
