deep chrome, not orange. It was taken by Mr. H. L. Andrewes, 

 September 1910, in the Nilgiri Hills (3500 ft.). 



" The yellow marks on the wing in both forms are so exactly 

 like those in the typical form that they cannot be regarded but as 

 varieties." (Bruiietti, 1. c., p. 241).

c? $ . Head yellow, often lemon-yellow, a dark brown spot or 

 pair of spots on back of occiput, a small elongate mark over base 

 of each antenna or at its side. Proboscis yellow or brownish 

 yellow, often with a brown streak on each side above, brown 

 below ; palpi with 1st joint brown, the remainder yellow, wholly 

 pubescent. Antennae much as in P. Iceta, except that the scape 

 is more black (probably sometimes wholly so). The whole 

 antenna in female black, shaped mainly as in fata, but the joints 

 more flattened, not at all annular. Thorax yellow, sometimes 

 tinged with a little orange, sometimes lemon-yellow. Three 

 dorsal brown stripes of the usual pattern in TIPULIDJE, the 

 median one beginning on the anterior margin, generally narrowly 

 divided in the middle ; the outer ones consist of an oval spot in 

 front of the suture, joined to one, sometimes two, contig'uous 

 spots behind the suture ; the three (or two) form a stripe from 

 well behind the shoulder to the posterior margin of the dorsuin ; 

 a brown streak at base of collare, carried on each side right down 

 at the sides and continued on to the fore coxae. Scutellum and 

 metanotum concolorous with thoracic dorsum ; a brown spot on 

 each side of the scutellutn, like a continuation of the outer 

 thoracic dorsal stripes. The metanotum with a brown mark 

 (sometimes divided) on hinder side. Sternopleurae with a broad 

 dark brown horizontal stripe on upper part and another on lower 

 part, sometimes indistinct (possibly occasionally absent) ; a brown 

 mark here and there on the rest of the pleurae. Abdomen yellow 

 or orange-yellow ; bases of segments more or less dark brown or 

 blackish, the extent of the colour variable, and apparently more 

 extensive in the female. The basal segment generally wholly 

 yellow, the apical one or two segments generally black. Genitalia 

 of male shining brownish yellow, with blackish marks and 

 pubescence. Ovipositor of female shining black. Legs: coxae 

 yellow or brownish yellow, often with dark brown streaks ; 

 femora dirty brownish yellow ; tibiae and tarsi similarly coloured 

 but darker, the former with a moderately narrow whitish ring at 

 base. Wings moderately deep brown, with yellow marks that 

 are variable, usually four in number and of considerable size. 

 Normally, two rather large round or oblong spots just below the 

 costa, the first placed clear of the base of the wing, its distal side
