Brachyunguis harmalae, sp. nov. 
Vern. ‘ Harmal ka Tela.’’ 
Host.—Harmal (Peganum harmala). 
MORPHOLOGICAL DESCRIPTION. 
Apterous viviparous female. Body medium sized, about a millimetre and a half 
in length, oval or egg-round ; fairly thickly covered with white powder. 
Colour green, like that of the leaves of its host ; deep green from the prothorax 
to the first two or three abdominal segments ; afterwards it becomes gradually lighter, 
and about the cornicles and behind them it is almost yellowish, with a very slight tinge 
of green on the last abdominal rings. There is frequently a light yellow coloured band 
stretching across the abdomen at the cornicular area. Beginning at the level of the 
cornicles eight conspicuous green spots on either side in the lateral grooves extend up 
to the head ; on the thoracic segments the spots are larger and look like depressions. 
Head brown, well rounded, about as long as broad with a median longitudinal 
line on the top, without any trace of frontal tubercles. 
Eyes shining red, rather well developed, with ocular tubercles. 
Antennae small, light green; distal part of fifth and whole of sixth joint black; 
hardly reaching up to the second abdominal spot; spur of the_sixth much shorter 
than the base, an important feature of its anatomy.

The thoracic segments are well marked off; the prothorax bears the lateral 
tubercles. Just below the carina or lateral edges there is a row of dark dots, seen 
when the insect is examined under a strong binocular lens. 
Cornicles very small, greenish, cylindrical, but with a clearly noticeable rim, 
much shorter than the cauda. 
Cauda somewhat long conical, with one or two indentations on either side from 
which bristles originate; a little less than double the cornicles. Colour greenish, but 
the edge is black reaching up to the broad base. 
Anal plate brown, in front of it is the somewhat crescentic, brown genital plate. 
Legs green up to the coxae, only the tarsi and a small part of the knee black; 
the tibiae in old specimens show a fuscous line-on the outer surface. | 
Ventral surface well segmented, with two lateral rows of green dots and very fine 
hairs across the rings; deeper green on the sternum. 
Rostrum rather long, greenish, last two joints dusky, reaching up to the third 
coxae. 
Face brownish, from where the rostrum arises outlined with black. 
Measurements.— The average of early-season specimens is given below; late in 
the season, about the middle of November, they are smaller in size.
