Occurrence. -1 have a series of the females and two males all taken at 
“ The Gap all in the immediate neighbourhood of jungle streams. 
Remarks.—I have no absolute surety that the male here described is 
really the same species as the female but it closely resembles the female. 
It is possible that Topomyia Tipuliformis is the male. The vertical spot in 
T minor is much larger relatively and absolutely than in T. Argentoventralis 
there are large triangular lateral spots on the first three segments of the 
former as well as the three bands on segments four to six present on 
t e abdomen of both. The central line in minor is much broader bein^ 
composed of four or five rows of scales and does not cover the first or last 
quarter of the middle line of the mesonotum. From T. Argyropalpis it is 
distinguished by the absence of white scales on the proboscis and palpi. 
And a slight difference in the position of the cross vein on the win 0- but 
the two species resemble one another very closely. 
Topomyia Argyropalpis. n. sp. 
Thorax with bronzy narrow scales and a central line of pearly-white 
round flat scales. Head with a large pearly-white patch on the vertex. 
Palpi pearly-white above. A white spot on the scutellum and large 
triangular peaily-vhite basal patches on the abdomen. Legs unbanded. 
Female Head. A patch of almost circular pearly-white scales on the 
\ ertex, the lest of the head being entirely covered with broad racquet-shaped 
scales purpie-bronze in colour; no upright scales; vertical bristles long, 
black in colour. Basal joint of antenna without scales, remaining 
joints blackish-brown with dark browm verticils. Palpi dark brown at 
the base silvery-white for the apical two-thirds, about one-fifth the length 
of the proboscis. Proboscis about as long as the abdomen rather slender, 
clad with dark brown scales. 
Thorax. Prothoracic lobes black, entirely covered with pearly-white 
circular scales. Mesonotum black with a line of pearly-white circular scales 
running down the centre the parts on either side thickly clad with bronze 
narrow-curved scales. Scutellum black with broad almost circular scales, 
pearly-white on the middle lobe, dark purple-brown on the lateral lobes. 
Pleurae dark brown with patches of elliptical silvery scales. Wings brown 
with dark brown scales, median scales narrow spatulate, lateral longer but 
similar in shape; fork cells long, first twice as long as its stem, much longer 
than the second, breadth of two cells equal; posterior cross vein about its own 
length from median. Coxae light yellowish-brown with silvery scales. 
Hind legs with pale ochraceous scales on the basal third and beneath for the 
whole distance, the rest of the leg with dark brown scales with coppery and 
bronzy reflections, mid leg with brown scales, fore legs damaged; mid 
ungues equal and simple. About the middle on either side of the 
metanotum there seems to be one small scale inserted but it is difficult in 
the type to be sure it is inserted and not merely lying on the metanotum. 
Having only one female I cannot confirm this. 
Abdomen. Above clad with dark purple scales, below with metallic- 
silvery scales which in a dried specimen take on a yellowish tinge the 
colour of the background; laterally there is a large pearly-white spot
