any further discussion of the nomenclature of the itch-mite. 
TROMBIDIIDAE 
Trombicula centropodis Hwing 
Trombicula centropodis Ewing, 1928, Proc. Ent. Soc. Washington, XXX, p. 78 (larva). 
Liperta.— Gbanga, September 26, 1926. Several larvae agglomerated 
within small, open, cup-shaped tumors of the skin on the thigh of a coucal 
Centropus senegalensis senegalensis (Linnaeus). 
The following is a copy of the original description: 
“Palpi not angulate laterally on the margins of large second segments; first palpal seta with 
several barbs; second palpal seta also with barbs. Palpal claw trifurcate, the accessory prongs 
arising from near the middle; inner accessory prong longer than the outer and reaching almost 
to the tip of claw proper. Chelicera with stout fang, only slightly curved. Dorsal plate as long as 
broad, front margin slightly incurved, posterior margin strongly arched outwardly and forming 
an angle at the median line. Pseudostigmata situated near the middle of dorsal plate; pseudostig- 
matic organs very long, setiform, basal half simple, distal half with barbs. Eyes situated about one- 
half the width of the dorsal plate laterally from the margins of the same; front eyes almost twice 
the diameter of the hind ones. Dorsal abdominal setae twenty in number, medium in length and 
tapering toward their tips. Front pair of legs longer than the second pair and about equal in length 
to the body of the unengorged larva. 
“Length of unengorged larva, 0.834 mm.; width, 0.23 mm. 
“The dorsal shield of this species is of an unusual shape, being similar to that of 7. ardeae 
(Trigardh). T. centropodis differs from this species in having much shorter body setae.” 
Leeuwenhoekia sp. 
Liperta.— Du River (Camp No. 3), larvae on a small bat, Petaha arge 
(Thomas), August 1926. (Identified by Dr. H. E. Ewing.) 
ANALGESIDAE 
Falculifer sp. 
BELGIAN Conco.— Western slopes of Mt. Ruwenzori, at about 7000 ft., 
numerous specimens of the hypopial stage in the connective tissue of the ab- 
domen of a wild pigeon, Columba arquatrix Temminck, December 19, 1926 
(J. P. Chapin). According to Dr. Chapin, a similar parasite was found in the 
same locality in the connective tissue of a plantain-eater, Ruwenzorornis john- 
stont (Sharpe). 
The adult mites of the genus Falculifer Railliet live freely on birds, feeding 
upon the feathers and epidermal scales. They probably do very little or no 
damage to the birds in that stage, but may be rather of service in keeping the 
skin and feathers clean. It is impossible to identify or describe the species of 
Ruwenzori from the hypopial stage. 
N. Banks (1915. ‘The Acarina or mites.’ U. 8. Dept. Agric. Rept. No. 108, 
pp. 123-125) gives the following interesting résumé of the life history of 
Falculifer rostratus (Buchholz), the common species of domestic pigeons: 1
