Pig. 4 Tromhicula subintermo-dia, n. sp. 
barbs. Dorsal setae formula: 2-8-6-6-6-4-4. 
Sternal setae 2-2. About 44 small setae ven- 
trally, behind coxae III. 
TYPE DATA: Holotype from Apodemus agra- 
rius, 2 miles southeast of Yonchon, Novem- 
ber 27, 1951. Deposited in the U. S. National 
Museum. 
COMMENTS: T. subintermedia can be sep- 
arated from T. intermedia by the dorsal setal 
formulae: in T. intermedia this is 2-10-8-8- 
6-4-2, considerably more setae than in sub- 
intermedia; from lanceolata the new species 
differs in the sensillae being nude or almost 
so, whereas the original illustration of lanceo- 
lata shows numerous rather long sensillae, 
and the scutal measurements of lanceolata and 
subintermedia differ appreciably.
