linging thereto until it succumbs. Larvae of Hemerobius and 
Shrysopa, and larvae and adults of Coccinellids and the nymphs of 
ertain Reduviidae occur on the pines and probably assist in checking 
his insect. The ruby-crowned kinglet has been observed eating 
he midges.

This species produces a rather common gall on Cypress, Ta x- 
odium distichum. The galls appear to originate as small, 
globose or oval, densely pruinose swellings with rudimentary leaves 
and located near the tips of the smaller, tender shoots. They vary 
in length from 5 to 8 mm, are spongy, and the green interior contains 
2 variable number of pale yellowish larvae grouped about the central 
axis of the shoot. At the same time we find more matured galls 
containing reddish or deep orange larvae, which would seem to 
indicate an extended period of flight and a prolonged oviposition. 
Transformations occur within the gall, exuviae being left protruding. 
From 3 to 8 larvae may occur in each swelling. Polygenotus 
proximusAshm. MS. (Insect Life, 4:125) was reared from the 
gall produced by this midge. 
Gall. Developing galls are globose or oval, densely pruinose, 
bear rudimentary leaves and are from 5 to 8 mm long. The fully 
developed gall may be 1.25 cm long, brown, and appears much as a 
small pineapple, owing to the numerous transverse elevations. The 
larvae in either type occur in oval cells grouped irregularly about 
the central axis. 
Larva. The small larvae are pale yellowish, scarcely .5 mm long. 
The full-grown larvae have a length about 1.75 mm, are reddish 
orange or deep orange and possess a clove-shaped, dark-brown or 
black breastbone. 
Doctor Riley described the living specimens as of a bright-red 
color, the head black and the thorax dusky above. The following 
was drafted from pinned specimens in the United States National 
Museum. 
Male. Length 1.25 mm. Antennae one-fourth longer than the 
body, thickly haired, yellowish brown; 14 segments, the fifth with 
stems one-half and one and one-half times their diameters; terminal 
segment, distal enlargement fusiform, strongly constricted basally
