Head yellowish ; front broad, carrying two groups of bristles.

Antennae short, reaching about half way down the back ; basal part concolorous 
with head, the distal part from fifth joint onwards black; sparingly hairy ; last joint 
slightly curved.

Actual lengths .. 0'26 O’I4 0'I2 0'08+0'20 mm. 
No sensoria are present except the normal primary ones. 
Prothorax as broad as head ; on the lateral sides of the groove behind is a small 
tubercle. 
Mesothorax large, with an irregular green black blotch, broad in front and nar- 
row behind and meeting with a smaller spot on the metathorax. Near the lateral 
edges there is another small faint dot. | 
Abdomen very bristly ; on the first abdominal segment there are two flattened 
latero-dorsal green spots and another in their middle with which they are often con- 
fluent. Another pair of broad crescentic bands passes internal to and around the 
bases of the cornicles, leaving large circular areas around them and extending up to 
the last segment but one. The seventh annulus also bears two greenish spots. The 
pattern is shown i in the figure. 
The cornicles in surface-view appear ring-like, very little above the body level, 
brown. A clear circular space of a light greenish colour brings them into relief. 
Undera high power, in lateral view, they are truncate, with a wide base and nar- 
rower somewhat flanged tip. There are circular lines over the basal part and a 
network of them on the distal part (see figure). 
The cauda projects beyond the body as a spherical knob, between which and the 
broad base there is a narrow constriction. Knob yellow-coloured; there are a few 
curved hairs over it ; length about double the cornicles. 
The anal plate can be seen from above; it is almost rectangular, with a shallow 
but a very distinct notch or depression in the middle of the posterior border. Its 
bilobed character is just indicated and is not at all so well marked as in Callipterina. 
The genital plate is not well seen; the colour, like the anal plate, is greenish- 
yellow, but the vulva between is quite large. 
Rudimentary gonapophyses four ?.! 
Legs normal, hairy ; of the same colour as the body throughout except the dusky 
tarsi; the ‘‘ sole-pustules” are indistinct above them. 
Rostrum very light greenish, almost hyaline, showing a clear narrow brown groove 
in its middle running up to the slightly darker extreme tip. It reaches up to the third 
coxae. 
1 [The number of rudimentary gonapophysae was not filled in in the original manuscript; very 
likely the number is 4, as in other Chaithophorinae. P. v. d. G.].
