lime, which is said to destroy the larve of the pest”; but neither this

Cecidomyia muricate, Meade. 
This species was discovered by Mr. Inchbald, and described by 
Dr. Meade,* in 1886, the perfect insect not being known before. 
g.—Head black, covered by white hairs. Face brownish-yellow, 
inner margins of eyes bordered by a yellow line. Palpi light yellow. 
Antennz composed of seventeen joints, blackish-brown, nearly 
-as long as the body. Joints petiolate and verticillate, white hairs. 
Thorax blackish-brown, marked by three dark stripes, running 
longitudinally and gradually becoming less conspicuous as they pass 
backwards. Thorax covered by white and gray hairs, especially at 
the sides and in two lines on the dorsum. Roots of wings bright red. 
Shoulders marked with a yellow spot. Scutellum black at the base, 
reddish-yellow towards the end and sides. 
Metathorax black. Abdomen dark reddish-brown, the first 
segment almost black ; white hairs upon all the segments, especially 
at the sides, and a few at the borders of the segments. A brown 
band runs down the ventral surface on a flesh- coloured ground. 
Last two segments narrow and testaceous in colour, the male 
armature also testaceous. Halteres brown, knobs clothed with 
patches of white hairs. 
Wings covered with a dark pubescence, veins clothed with scales, 
having a reddish tinge. The second longitudinal vein is straight 
and joins the costal in front of the apex of the wing. The under 
surfaces of the brown legs are clothed with silvery hairs. The knees 
and ends of tarsi pink. 
? The female is distinguished from the male by the following 
points: 1. The antennze smaller than g—about half the length of 
the body. 2. Joints of antennz sessile ; they lessen gradually as they 
approach the apex, the last joint being half as long as the pre- 
ceding one. 3. Abdomen lighter than the ¢. 4. Zhe oviduct long 
and slender, basal joint round, yellow; second joint elongated and 
brownish-black ; the last joint being long and slender, yellow at base, 
brown in centre, and pink at the extremity. No terminal lamelle. 
The larve are found on Carex muricata, amongst the seeds and 
flower spikes. They feed “within the utricle on the embryo nucule, 
pupating in the spikelet.”+ In this position they pupate, forming a 
papery cocoon, towards the end of the autumn.
