patches of black bristles ; apices of femora and tibiae swollen. A band of 



lighter scales running along the under surfaces of all the legs (especially 



marked on the mid legs) to the tips. A yellow spot at the apex of hind 



tibije. Knee spots not defined. Ungues equal and simple. Wings, the 

 apical portions of the first four long veins densely scaled with broad fan- 

 shaped scales. The two median rows of broad scales are represented by 

 narrow elongated ones on the bases of the second and third, first part of 

 the base of the fourth and upper arm of the fifth. The remainder of the 

 base of the fourth and the lower arm of the fifth have long scales on one 

 side only. The base of the fifth has broad scales only throughout its 

 length. On the sixth long vein the scales are all slender and elongated. 

 First submarginal cell as wide as but much longer than the second 

 posterior, about four times as long as the stem ; second posterior with the 

 stem about half length of the cell. Posterior cross vein about twice its 

 own length distant from the mid cross vein. Halteres with pale stems and 

 knobs, the latter mottled with dark areas. Length, 2.5 mm. 



^ . — Palpi black, copiously speckled with yellowish scales, slender, 

 larger than the proboscis, the tip of the latter reaching to the middle of 

 the penultimate joint ; long hairs along the sides and under surfaces of 

 the first two joints and apex of the antepenultimate joint. Both terminal 

 joints and apex of antepenultimate joint slightly swollen. Abdomen 

 black, with scattered dull white scales : these form an ill-defined band 

 down the centre of the abdomen, lateral patches of silvery scales on the 

 fifth, sixth and seventh segments. Legs black, conspicuous lines of lighter 

 scales on the under surfaces of all the legs. Ungues of the fore and mid 

 tarsi unequal and uniserrate ; larger with one long median blunt tooth, 

 smaller with a small basal tooth. Ungues of the hind tarsus equal and 

 simple. Length, 2.5 mm. 



The following points were noted in the adult larva : Fully grown 

 larva about y^ inch long, with relatively large head and thorax. Antennae 

 large and prominent, larger than the head, slightly curved in lower third, 

 somewhat swollen in the basal half, only moderately infuscated, rather 

 more so above the lateral tuft and at the extreme base. Tuft a little above 

 the middle, of about twelve fine flattened hairs measuring about three- 

 quarters length of the antennal shaft. Apex with four large deeply 

 infuscated spines, the two longest about half the length of shaft. Surface 

 covered with many fine chitinous spines, especially along the outer aspect. 

 Mentum small, with about fifteen teeth, apical tooth prominent. Upper
