42 Psyche [April 
mm. from the type of Scleroderma quadridentatum. Although I 
cannot make out any palpal combs, the animal is evidently not a 
Cheyletiella. 
DipTERA. 
Winnertziola burmitica sp. nov. (Cecidomyiide). 
Q. Piceous, including legs and antennze; wings clear, nervures — 
ferruginous; surface of wings not conspicuously hairy, margin with 
long hairs; thorax narrow; abdomen long and narrow, the caudal 
appendages long and slender; venation as usual in the genus, the 
cross-vein not very oblique; antennz apparently 11-jointed, but 
there is doubtless a second basal joint not seen, making 12 in all; 
antennal joints with long hairs, but no circumfili, whether with sur- 
face markings cannot 
be determined; the 
three joints before the 
last broader basally 
than apically; palpi 
large, apparently 3- 
jointed, but there is 
probably a small basal

before the last not ap- 
preciably shorter than 
the last; tarsi with 5 joints, basal joint very short, second long; 
claws small, apparently simple, emporium so small that it cannot 
be clearly made out; halteres very large, the large club dark brown. 
The following measurements are in microns: total length about 
1760; length of wing about 1120; length of antennz apparently 
about 400, but they are seen obliquely, and are probably about 
480; last joint of palpus 57; width of club of halter 64; length of 
hind femur 400; hind tarsal joints (1) 64, (2) 240, (3) 112, (4) 80, 
(5) 64. 
Burmese amber, from R. C. J. Swinhoe; in the same slab as the 
type of Enicocephalus swinhoei, and 10 mm. from it. This may pos- 
sibly be separable from Winnertziola on account of the long caudal 
appendages, the form of the palpi, the probably simple claws, etc., 
but some of these differences are doubtful, and the others are 
slight, so a separate genus hardly seems to be required. The allied 
genus Winnertzia is known from Baltic amber.
