6o SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 28 



Diagnosis of larva. — A nonscrobiculate species with 2 pairs of sub- 

 marginal or submedial usurped setae on the scutum. Palpal setal for- 

 mula B/N{b)/NNF. Palpal claw 3-pronged. Two pairs of eyes but 

 these somewhat reduced. PPL-i almost midway between PL and 

 PPL-2 but nearer PLs. PPL-2 midway between posterior margin 

 of scutum and PPL-i. PPlV-i is 53 microns (±3); PPW-2, 41 

 ( ±8) ; PPP-i, 109 ( ±7) ; PPP-2, 59 ( ±4). Scutum about one and 

 nine-tenths times as long as broad at maximum. With two types of 

 pits on scutum : one slightly smaller than setal bases, evenly distrib- 

 uted beyond sensillary bases ; and the second type consisting of scat- 

 tered minute punctae. With about 32 dorsal setae (excluding usurped 

 setae) usually arranged 2.4.4.6.6.4.4.2. With about 50 to 60 ven- 

 tral abdominal setae, including approximately 20 postanals. Coxae 

 i-setose. The ratio of length to breadth of coxa III is 1.42.

Type material. — Holotype and 12 paratypes ex "Rattus edwardsi 

 ciliatus Bonhote," Malaya, Pahang, Fraser's Hill, elevation 4,500 feet. 

 According to Fuller (1952), "Holotype No. 1932-7-18-19 and two 

 paratypes, Nos. 1932-7-18-20 and 21, in British Museum (Natural 

 Flistory). Paratypes . . . also in . . , U. S. National Museum; the 

 Molteno Institute, Cambridge, England; King Edward VII College 

 of Medicine, Singapore; and the Rijksmuseum van Natuurlijke 

 Historic, Leiden." 



Records and comment. — One specimen ex Rattus edwardsi, Malaya, 

 Pahang, Fraser's Hill, elevation 4,500 feet (R. Traub, for U. S. Army 

 Medical Research Unit), January 3, 1950. Five ex RattKS sabanus, 

 Malaya, Selangor, Ulu Langat, in primary forest at approximately 

 2,500 feet elevation; Colonial Office Medical Research Unit, Janu- 

 ary 15, 1952. One ex Rattus miilleri, ibid., but August 5, 1952. 



These are the first records since the original description. As can 

 be seen from the records, this sf)ecies seems to be a characteristic 

 inhabitant of the mountain forests of Malaya. Despite intensive col- 

 lecting by the Colonial Office Medical Research Unit and the U. S. 

 Army Medical Research Units in the vicinity of Kuala Lumpur, this 

 species has not been encountered in scrub terrain.
