Coxa III (fig. 85) relatively broad, four-fifths (or greater) as broad 

 as long; with a prominent lobe at posterolateral angle (ratio of length 

 to breadth, 50: 45 = i.i ) ; the single seta submedial in insertion. With 

 sternal setae and sensory setae essentially as in G. exills, new species. 



Type material. — Holotype (U.S.A.T.C. No. 561-1) ex Rattus sp., 

 North Burma, 20 miles northwest of Myitkyina on Mogaung Road, 

 January 24, 1945 (U. S. A. Typhus Commission). Three paratypes 

 as follows: i, ibid., but ex another Raitiis (U.S.A.T.C. No. 552-23) ; 

 I, ibid., but ex Rattus r. sladcni (Anderson), May 22 (U.S.A.T.C. 

 No. 1035-10) ; I same as the last but from a second individual 

 (U.S.A.T.C. No. 1044-13). Holotype (U.S.N.M. No. 2164) and 

 one paratype deposited in U. S. National Museum. Two paratypes 

 in collection of senior author. 



Comment. — The specimens were all collected in the primary forest 

 or at the periphery of such true jungle. The species is named for 

 Thomas M. Evans of the Department of Entomology, Army IMedi- 

 cal Service Graduate School, Washington, D. C, who prepared the 

 illustrations for this paper, and whose very fine drawings have done 

 much to enhance the knowledge of Indo-Malayan trombiculid and 

 laelaptid mites. 



GAHRLIEPIA (GAHRLIEPIA) PICTA, new species 



Figures 92-99 



Diagnosis of larva. — Separable from the described Asian Gahr- 

 liepia possessing scrobiculate scuta in that there are 8 usurped scutal 

 setae (not 4, or else 17 or more) and in that these are all medial. Fur- 

 ther distinguishable from G. (G.) evansi, new species, in that the 

 scutal scrobiculi are not all evenly ovate or elliptical but instead are 

 often somewhat ameboid, trigonal or subquadrate or otherwise 

 irregular. 



Description of larva. — Body: Subovate, about 423x282 microns 

 in fairly engorged holotype. Eyes apparently double. Gnafhosoma: 

 Chelicerae about four to five times as long as broad ; apex of distal tri- 

 cuspid cap long, acuminate; with a distinct nubbin somewhat proxi- 

 mad of base of cap. Palpal setal formula b/b/bfNb. Palpal claw 

 3-pronged. Scutum: Long, broadly and evenly tongue-shaped; 179
