Allied to A', latipes and A'^. tenuiscapa, most so to the 

 latter species ; the females present no striking specific 

 difference ; the species was established upon the differences 

 observable in the males ; the anterior tarsi are dilated as in 

 A'. tenuiscapa,\)\\t they are fringed Avitli black pubescence, 

 and the second, third and fourth joints of the tarsi are of 

 equal length. I have only seen three males ; they agree in 

 these particulars, but may ])ossibly prove to be a variety of 

 X. tenuiscapa. Length of female fourteen lines ; of the 

 male twelve. 



Hah. — Ternate.

The female is black ; the thorax above and at the sides 

 with bright yellow pubescence ; on the face and thorax 

 beneath it is sooty-black ; there is also a little yellow on 

 the hinder margin of the vertex ; the abdomen shining, 

 and covered with shallow punctures ; the sides and apex 

 fringed with black pid^escence. The male is similarly 

 coloured ; it differs in having the yellow ]nibescence con- 

 tinued on to the basal segment of the abdomen ; the cly- 

 peus or spot at the base of the mandibles, the scape of the 

 antenna in front, and the flagellum beyond the second 

 joint beneath, yellowish-white ; the eyes are large and 

 approximating ; the anterior and intermediate tarsi with 

 rufo-fulvous pubescence ; the posterior tibite have at their 

 apex a projecting somewhat quadrate appendage ; the 

 wings in both sexes are fuscous, not dark, and^ have a 

 pur|3le and coppery iridescence. Length nine to ten lines.

This species closely resembles A", clreumvolans of Ja- 

 pan, of which it may be a variety ; it differs from it in 

 havmg pale pubescence on its tarsi, and in not having any 

 yellow pubescence on the abdomen.
