that the two together form a rough triangle. The colour is 
usually light greenish-brown, the head being darker. 
“These larvae are very alert, diving on the least alarm and 
lying motionless on the bottom. Jf any mud is taken up with 
the water, it is most ditticult to detect them, so patiently do they 
sham death. They do not seem to feed on confervae at all. Ii 
anything of the kind is put into the water with them, they are 
apt to entangle themselves and die, by drowning, I suppose. 
They feed either at the surface or at the bottom ; for this reason, 
perhaps, they affect shallow, clear water. I found them in rice- 
fields and small rocky streams, but most abundantly in boggy 
cround adjoining rice-fields.”

The following is D6nitz’s description, translated for me by 
Miss Falcke :-— 
“ Diagnosis.—Superior fork almost double the length of the inferior 
fork. Four typical spots on the anterior margin at equal distances one 
from the other; beneath the terminal half of the second spot there is a 
dark streak on the first longitudinal vein. There is no spot at the com- 
mencement of the third vein. Vein six has three spots, the central one, 
very long, is frequently amalgamated with the small radical spot. 
The ciliated margin is parti-coloured. Legs equally dark, tarsal 
articulations, slightly lighter. 
Ends of the palpi white, with a dark ring on the other side of the 
centre of the fourth palpal joint.

Flead.—Tuft on vertex white. Palpi dark, with light terminations. 
The first jomt has broad light markings, the end of the second joint, as 
also the terminal joints, light, the last but: one has a fairly narrow ring 
about the middle. The terminal half-of the proboscis is light. Length 
of jeints of palpi, 0°5—0°5—0°3—0°13 mm. . 
Thorax (yellew in the alcohol) with a dark central streak right 
through. The grey field lying near is divided from the front to the 
middle on each side by an ochre-yelluw longitudinal stripe. There is an 
olive-brown spot behind the sutura transversalis, while a stripe of the 
same tone, but somewhat lighter, goes over the roots of the wings in a 
backward direction. The side-fields thus ensuing are again divided 
longitudinally by a narrow darker stripe, which commences next to the 
above-mentioned longitudinal stripes of the anterior half of the thorax. 
Metanotum ochre-yellow. 
Wings——The fork-cell of the second longitudinal vein lies perpen-
