whole anteniije appearing iu certain lights tinged with reddish 

 yellow. Proboscis shining reddish yellow, ^\•ith large oval grey 

 hairy labella placed at the base. Palpi long, slender, blackish, the 

 1st pint not much thickened. Thorax : dorsum ash-grey, with 

 scattered short bright yellow hairs, and three moderately narrow 

 black stripes beginning just behind the anterior margin but not 

 continued to the posterior one. Viewed from a lo\\- angle in 

 front the dorsum appears blackish, with foiu' ash-grey stripes of 

 which the two outer ones are constricted in the middle on their 

 outer edges. Sides of thorax blackish grey, with ash-grey reflec- 

 tions on the ])leurse. Abdomen dull black (apparently denuded 

 of pubescence). Legs: coxae and femora yellowish or brownish 

 yellow, the latter more or less brown towards the tips, especially 

 on the posterior legs. Pore tibiso dark brown ; posterior tibiae 

 pale yellowish on basal half, brownish or dark brown on apical 

 half, "the proportions being variable. Fore tarsi black, the meta- 

 tarsus, 2nd and 3rd joints large ; middle tarsi brownish yellow at 

 the base, the joints very narrowly black-tipped, the last t\\o or 

 three joints wholly black, with no undue dilatation of any of the 

 joints ; hind metatarsus considerably incrassated, pale whitish 

 yellow, with black tip, the next joint pale, narrowly black-tipped, 

 the remainder black, the joints, except the apical one, dilated. 

 Wings colourless, venation normal ; halteres lemon-yellow.

Described from five specimens taken by Mr. E. E. Green and 

 Mr. Gravely at Peradeniya, 1500-lGOO ft., Ceylon, vii. 1911 (type), 

 xii. 10 and 2. vi. 10.

In one specimen the frons is of equal width throughout, in the 

 others of triangular form, broad at the vertex and narroviing 

 gradually to just above the antennae. This is the case with the 

 other species previously described by me, and it may be a question 

 of shrinkage, the eyes inmost females being much sunken in dried 

 specimens. The striped thorax will distinguish this species at 

 once from all other Oriental ones.
