Genus Theobaldia. . 151 
Cases have occurred, especially in women, where there have been four or 
five simultaneous but separate punctures, and the patient has suffered so 
much malaise as to retire to bed with fever ranging up to 101° F. 
(3) The hard swelling is slight or absent, but there is great and 
extensive cedema. A case occurred in the practice of a friend of mine in 
which there was a puncture on the mau’s hand; the whole arm inflamed, 
and was extremely painful, with oedematous swelling extending up to the 
shoulder joint. Our own cook had a puncture this autumn on the fore- 
arm, and developed a regular attack of ‘‘ water in the elbow joint,” so 
that the arm became almost immovable. 
This year I caught specimens of the ? of this species as late as 
Jan. 13 in a summer-house with glass windows, as well as in our own 
house. I saw no males after the second week in November, 1902, and at 
that time I: noticed on a sunny day, in a warm nook of our garden, 
numbers of this gnat—all 9—tying about and settling on the stems of 
plants and inserting their proboscides, apparently engaged in sucking. The 
two plants attacked were the periwinkle (V. major) and young wallflowers. 
Most people at Weston are well acquainted with this species owing to 
its speckled wings, and it is usually to be met with in autumn in the 
woods on Worlebury Hill behind Weston on the north. Indeed, it is 
sometimes spoken of as the ‘ Wood Gnat.” 
Larvae and pupae (Fig. 81).—The larvae are found in 
water-barrels, small pools, etc. They are quite large, when 
mature reaching nearly three-quarters of an inch in length. In 
colour they are pale greyish brown; the head is smaller than 
the thorax ; the antennae with terminal spines and a tuft on the 
inner side; the siphon is rather short and thick. The pupa 
(Fig. 81, b) has rather curved, truncated respiratory siphons 
and prominent anal fins, and a very distinct tree-like tuft on the 
first abdominal segment. The eggs are laid in large boat-shaped 
masses.
