A BEAUTIFUL CRANE-FLY FROM SIAM 
By T. D. A. Cockerell 
I have lately received from Dr. and Mrs. James W. 
McKean along with many other insects, an extremely hand- 
some Tipula collected at Chiengmai, Siam, June 28, 1928. 
The insect was so remarkable that I looked it up in the 
literature, and decided that it was allied to T. pedata Wied., 
but new. 
Tipula (Tipulodina) mckeani n. sp. 
$ . Length 28 mm., wing 18 mm. ; hind tibia 20.2, hind 
tarsus 21.5, hind femur 19, ovipositor 1, antennae about 3, 
proboscis 1.5 mm. 
Antennal scape white at base, more than apical half 
brown; flagellar joints brown, with somewhat swollen black 
base, which carries rather long hairs. Facial and frontal 
regions whitish, with a dusky stripe in middle of front; 
sides of snout ochreous, posterior part of head dark brown. 
Thorax dorsally pale brownish grey, a narrow dark brown 
stripe anteriorly, and the lateral areas broadly pallid, the 
pleural region whitish; halteres light brown. Wings clear 
hyaline, marked with dark brown in the manner of T. pedata 
Wied, except that there is no clear costoapical spot, though 
the color in this region is paler, and the cell R5 is clear 
except at extreme base; there is a small suffused brown 
spot on the lower margin of cell M, just about the middle. 
Abdomen dark brown above, beneath pale and flavescent, 
segments more or less pallid along apical margins. Femora 
broad, with blackened apex, the anterior pair broadly dull 
luteous subapically. Anterior and middle tibiae black, with 
a portion 4.5 mm. long and about 3 mm. from apex, creamy 
white ; their tarsi with about the basal 7 mm. black and the 
rest creamy white ; hind tibiae with an additional white ring,
