disk slightly, transversely wrinkled, impunctate. Elytra 
relatively a little shorter than in jordani ; each with outer 
apical angle spined, sutural angle not distinctly toothed, 
humeral prominence present but less developed and less 
acute than in jordani; surface moderately punctate, the 
punctures usually separated from each other by more 
than their own diameters. Male genitalia as figured. 
Length 10-11 ; width between 3 and 3^ mm. 
Holotype and one paratype both from north side 
of Milne Bay, eastern tip of New Guinea, December 1943, 
taken by myself. Types in the Museum of Comparative 
Zoology: Type No. 27734. 
This new species is slightly smaller and less elongate 
than Caledonomorpha jordani W. Horn, differs in ground 
color of the upper surface, lacks a distinct tooth at the 
apical sutural angle of the elytron, has less prominent 
and less acute humeral prominences, and differs slightly 
in other ways. 
Caledonomorpha is the only genus of tiger beetles 
peculiar to New Guinea. C. jordani , the only previously 
known species, is apparently confined to eastern New 
Guinea and adjacent small islands. It was described 
from Fergusson (Island) and the Astrolabe Mts., and in 
the M.C.Z. we have a series of 8 specimens from Mt. 
Lamington and Dobodura. It is rather surprising to 
find a second eastern New Guinea species at Milne Bay. 
In case Horn’s original series may have been mixed, I 
here designate the form figured in Genera Insectorum 
( W . Horn 1910 , t. 11 , /. 12 ) as typical jordani. Possibly 
additional species remain to be discovered in western 
New Guinea. 
I collected C. jordani, in northern foothills of the Owen 
Stanley Range near Dobodura, on stones and shrubs 
along small, very rapid brooks in heavy forest. Probably 
C. milneana lives in a similar habitat, although I do not 
remember the circumstances under which the types were 
collected.
