Ptychoptera tibialis, Brun. 



p. alrltarsis, Hnin.. Rer. Iiul. Mus., VI, p. 234 $ (1911). 



My atritarsis is only the 9 of tibialis. I took a long series of this 

 species at Darjiling in June, 1917 and it shows some variation in the 

 coloration of the legs. In the (^ the anterior tibiae are mainly black, 

 the apical half of the middle pair being more or less yellowish ; in the 9. 

 the anterior tibiae are wholly yellow, at most the basal part of the 

 middle pair a little blackish. As regards the hind femora in the $, all 

 grades are present from a distinct black basal half to wholly orange 

 yellow. The antennae are certainly only IS-jointed but the last joint, 

 though attenuated, is only from slightly longer than to one and a half 

 times as long as the penultimate, and not twice as long as stated in 

 my description. 



Ptychoptera annandalei, sp. nov. 



^. Southsm Shan States. Long. 6 mm. 



Head and palpi pale brownish-yellow ; frons, vertex and upper part 

 of occiput brilhantly shining dark blue ; antennae about as long as 

 abdomxcn ; scape bright yellow, about basal half of first flagellar joint 

 yellowish, rest of antennae black with microscopic greyish pubescence 

 and a few longer hairs. 



Thorax. — Dorsum brilliantly shining dark blue, the colour extending 

 posteriorly over the whole of the metanotum except for a large oblong 

 yellow spot in the centre, the blue colour everywhere very sharply 

 delineated from the pale yellow sides of the thorax and the very small 

 bright yellow scutellum. 



Abdomen brownish-yellow, hind margins of segments with more 

 or less narrow black bands, broadest on last segment, very narrow on 

 penultimate segment. Genitalia large, conspicuous and complex, 

 consisting apparently of two pairs of large cl&spers, the second joint 

 of the upper pair provided on the upper side with a comb-like organ 

 of stiff black bristles. A small ventral plate, produced into two 

 long style-like hairy fingers, curved upwards and ending in sharp 

 points. 



Legs yellowish, femora and tibiae narrowly black towards tips ; tarsi 

 black. 



Wings pale grey, costal cell yellowish ; two narrow pale blackish 

 transverse bands of varying intensity (as in the second specimen they 

 are much paler) ; the first across the middle of the wing, over the " cross 

 veins," the second from the rather small black o^'al stigma, across the 

 bases of the " forked cells." Halteres black, extreme base of stems 

 yellowish. 



Described from two (^ ^ in the Indian Museum from Kalaw, 4,000— 

 4,500 ft.. Southern Shan States, Burma lO-iii-1917 (Gravely). Not 

 uncommon at the roots of grass at dusk, but difficult to capture.
