l8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I28 



thosoma: Chelicerae about four and a half times as long as broad 

 near base. Palpal setal formula B/f/NNN. Palpal claw 3-pronged. 

 Scutum: Somewhat less than i^ times as long as broad (146X 102 

 microns) ; broadest at about level of anterior third ; slightly constricted 

 between levels of PPL-2 and PPL-S- Caudal margin relatively sub- 

 truncate. AL setae at anterolateral angles of scutum ; somewhat plu- 

 mose ; in vertical line with sensillae bases. PLs marginal ; resembling 

 ALs but slightly longer than ALs. SB inserted at level midway be- 

 tween ALs and PLs. Sensillae absent in specimen. With 6 usurped 

 setae arranged in 3 rows of 2 each. With 2 kinds of punctae — one 

 almost the size of the setal bases and uniformly distributed posterior 

 to SB; the second type, the ordinary micropunctae, scattered over 

 the scutum. Body setae: Dorsal setae similar to scutal setae; about

32 in number arranged 2.4.4.6.6.4.4.2 (excluding usurped setae). 

 With about 48 ventral setae, of which 18 are postanals. True ventrals 

 short, about 20 to 23 microns; sparsely plumed. Legs: Coxa III 

 length to breadth in ratio of 63 : 40 microns ( = 1.6) . With two pairs 

 of typical sternal setae. Sensory setae as in G. exilis. 



Type material. — Holotype ex Rattus flavipectus yunnanensis (An- 

 derson), China-Burma border on Stilwell Road, April 30, 1945 

 (U. S. A. Typhus Commission). No other specimen known. De- 

 posited in U. S. National Museum (U.S.N.M. No. 2158). 



GAHRLIEPIA (GAHRLIEPIA) ELBELI, new species 



Figures 43-50 



Diagnosis of larva. — Near G. tenella, new species, especially as re- 

 gards subtruncate posterior margin of scutum but readily separable 

 in that (i) the scutum (fig. 45) bears only 4 usurped setae, not 6 

 (fig- 37) ; (2) posterior third of scutum with lateral margins sub- 

 parallel to near apex instead of sloping to near apex. Separable from 

 other nonscrobiculate Gahrliepia with 4 usurped setae in that the 

 posterior margin of the scutum is subtruncate. Near G. cetrata Gater, 

 1932, but further distinguishable in that PW is less than 75 microns, 

 instead of in the vicinity of 90, and in that PPL-2 is immediately in 

 front of the posterior margin of the scutum (less than 14 microns) in- 

 stead of being midway between PPL-i and the posterior margin. Re-
