Cockingsia tenuipes n. sp. (figs. 5 G-K). 
Description of Larvae . — Shape oval but with sides somewhat flattened and when fully engorged with 
a slight medial constriction. Length (unfed) 26o[jl, width 1 56(x ; fully engorged, to 715(1, and 480(1 
respectively. Scutum roughly triangular with apex directed forward as an anterior median process 
bearing the 2 AM setae; sensillae filamentous and nude, their bases large, widely separated and in line of 
PL; scutal setae stiff and rod-like with indistinct serrations. Eyes 2-|-2, large, on ocular shields and closely 
adjacent to postero-lateral corners of scutum. Chclicerac small, non-serrate, and with only the apical 
cap. Galeal setae short, fine and nude. Palpi as figured, femur outwardly slightly rounded with a long 
shortly ciliated seta; genu cylindrical with a nude seta, tibia short with all 3 setae nude, and a bifurcate 
strong slightly curved claw; tarsus small with fine non-specialiscd setae. Dorsal setae short from 32U 
anteriorly to 42 [jl posteriorly, rod-like with indistinct serrations, 20 in number, and arranged 2.4.44.4.2. 
Vcntrally, no setae could be observed on the maxillae; coxae I with 2 long fine setae, II and III with 1 such 
seta; a pair between coxae III and then 4. 2. 2. 2., the median two the first four being close to the anus, and 
varying in length from i6;jl anteriorly to 39(jl posteriorly. Legs long and unusually slender, I (to tip of 
claw) 3I2(ji, II 312 (jl. III 338(jl ; tarsi I and II with sensory rod, III without any long nude seta; claws long, 
curved and single. Empodium absent. Spiracle between gnathosoma and coxae I present, but only 
beginning of tracheae observed.

Loc. and Host . — This genus and species is described from specimens taken from the wings of a giant 
longicorn beetle from Sungei Buloh, Selangor, Malaya, 17. viii. 1948. ( J . R. Audy). 
Remarks . — The affinities of this species are discussed under the generic description. 
Family Trombidiidae Leach, 1815 
Subfamily Trombellinae Thor, 1935 
Genus Audyana nov. 
Scutum somewhat rectangular, with 2 AM, 2 AL, and 2 PL setae, of which the AM and 
AL setae are modified to form short claviform organs, the AL being situated in line with 
sensillae bases and lateral to these, but nearer than to the lateral margins; PL setae long and 
normal but mid-shaft very slightly thickened; sensillae long and narrowly lanceolate with fine 
indistinct ciliations; anterior scutal margin concave, without median process, but extending 
in front and the whole way across is a wide more or less hyaline part with its anterior margin 
flattened (whether this is the anterior part of the scutum is uncertain). Legs: I 7-, II and III 
6- segmented, tarsi furnished with only a single claw, and no empodium; coxae I with 2 fine, 
ciliated normal setae, II and III with 1 short claviform setae as in AM and AL; palpi stout, 
tibial claws short, equal, stumpy; maxillae and femora with a stout short claviform seta, genu 
with a long straight nude seta; tibia with 3 setae nude and straight; tarsus conical over-reaching 
claws, and apically with 2 long strong spines and with 4 to 5 nude setae. Chelicerae strongly 
curved, in addition to a minute apical cap, with two small subapical dorsal teeth. Galeal setae 
Pabsent. Eyes apparently absent. No stigmata and tracheae observed. Dorsal and ventral 
setae tapering, short and indistinctly ciliated.
