wings. The scales of the wings are black and white and give 

 to the wings a distinctively grayish appearance. The base of 

 the third longitudinal vein, where it meets the cross- veins, has 

 a small but distinct black patch of scales (Fig. 1, d). 



The legs are banded and speckled with yellowish white scales, 

 giving the mosquito a distinctive appearance. The femora of 

 all the legs have a pale band near the apex of each (Fig. I, /), 

 and the knees are white. The tibiae are strikingly speckled 

 with patches of white scales on a background of black scales. 

 The metatarsi have a pale ring at the base of each and a pale 

 band in the middle (Fig. I, e'). The first two tarsi of the front 

 legs are banded at the bases with white (Fig. I). The others 

 are black. All the tarsi of the hind legs are banded with 

 white. 



The abdomen (Fig. I, m), also has very characteristic mark- 

 ings. A few yellow scales and long hairs are found on the first 

 segment. Each of the next three segments has a triangular 

 patch of creamy scales on the apical border, those of the third 

 and fourth segments being broken in the middle. The patches 

 on the fifth and sixth segments are divided in the middle thus 

 forming distinct lateral spots. 



As Mr. Theobald says, "it is a very distinct species, easily 

 recognized by the black speck on the wing, the curious banding 

 and mottling of the legs and the adornment of the abdomen."

Anthidium jugatorium Say. — A study of the description of this bee 

 shows that it is a Dianthidium , very close to D. petpictum (Ckll.). It 

 will therefore stand as Dianthidium jugatorium. — T. D. A. Cockerell.
