Comments. — One specimen from Assam (Ledo vicinity, 22-mile mark on Stilwell Road), 
ex Suncus , agrees fully with the above description. It was collected from the type host and 
locality of G. liota n. sp. above, a species which is close to G. helata n. sp. as noted in the 
diagnosis. However, such a geographic distribution is not unique in this genus. According to 
our current concepts, the differences in the proportions of the scutum indicate we are dealing 
with full species, but the possibility of extreme variations within one species must be borne 
in mind. 
Gahrliepia (Schongastiella) birella n. sp. (figs. 26-34). 
Diagnosis of Larva. — Readily separable from all species of Schongastiella known to date 
by the conspicuous straight row of greatly enlarged dorsal bristles w T hich extend on each side 
in an oblique sublateral line from level of anterior margin of scutum to lateroposterior margin 
of body, and by the well-developed anal plate (which is even more specialised in a new species 
described below). Agrees with G. erula n. sp. in coxa III being unisetose and in possessing a 
scutum which is broadly ovate posteriorly and with PW about 66-70^. Further separable 
from erula by PSB being below 86, not above 100. 
Description of Larva. — Body: ovate, about 325(1. X 250^ when engorged. Eye apparently single, but 
indistinct in specimens extant. Gnathosome: of type characteristic of subgenus, but palpal coxae and 
femora scarcely punctate. Scutum: definitely punctate; about three-fourths as broad as long (about 
75 x 103(1. in holotype); broad throughout, but slightly angled at level of PL; between AL and PL lateral 
margins somewhat oblique, diverging towards rear; these margins straight between AL and PPL but 
becoming convex at PPL so that scutum is somewhat constricted above these bristles; caudal margin 
evenly rounded. Sensillae absent in known specimens. Body Setae: Bases of dorsal and ventral setae

* Dorsal setae in 
prominent row become progressively larger proceeding caudad. 
somewhat enlarged, prominent. Dorsal setae of two types : a thin, sparsely plumed form, only about 200. 
in length, about ten in number, all posterior to scutum and subdorsal in position; a second type, much 
stouter, ranging 32-50 (x in length, the longer ones more posterior in position, about eight on each side, 
forming a well-developed sublateral vertical row. Ventral setae about 36 in number, about I2(x in length. 
Anal opening surrounded by an ovate bivalvular sclerotization, the structure lying on a distinct slightly 
crenulate, punctate plate about 30 x 45(1. (fig. 28). 
Type Material. — Holotype (U.S.N.M. 2070, Colonial Office Research Unit 25369) ex Rattus bowersi 
(Anderson), Malaya, Selangor, Ulu Langat, 4. iii. 1952. (jf. R. Audy ) ; deposited in U.S. National Museum. 
A paratype (C.O.R.U. 25263) ex Rattus , Malaya, Selangor, Kepong, ibid; in collection of senior author. 
Gahrliepia (Schongastiella) arona n. sp. (figs. 35-43, p. 97). 
Diagnosis of Larva. — Agrees with G. (S.) birella n. sp. in possessing a sclerotized anal plate 
(the only two species in the genus so characterized). Readily separated from birella by the 
absence of a row of enlarged dorsal bristles on each side of the scutum; by possessing longer 
AL (29!^ versus 19-21) by the greater degree of sclerotization of the anal valvular sclerite and 
anal plate; the anal plate 3/4 as broad as long instead of virtually as broad as long; anal plate 
smooth, not punctate ; and by the scutum being evenly rounded laterally.
