12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I28 



Type material. — Holotype and 24 paratypes (U.S.A.T.C. No. 972) 

 ex Rattus flavipectus yunnanensis (Anderson), China-Burma Border, 

 Stilwell Road, April 30, 1945 (D. D. Millspaugh, for U. S. A. Typhus 

 Commission). Holotype (U.S.N.M. No. 2155) deposited in U. S. 

 National Museum. Paratypes distributed as for G. exilis, new species. 



Comment. — The larger punctations or excrescences on the scutum 

 suggest the modifications of the "ornate" species of Gahrliepia and 

 indicate that G. fimbriata is an intermediate type in this regard. 



GAHRLIEPIA (GAHRLIEPIA) DARITA, new species 



Figures 19-26 



Diagnosis of larva. — Near G. fletcheri Gater, 1932, but separable 

 in that the punctations are of uniform size instead of two types (cf. 

 fig. 161, G. fletcheri) ; and in that there are 17 to 22 dorsal setae 

 usurped by the scutum, instead of merely 10 to 17 (usually 11 or 12, 

 rarely more than 14) such usurped setae; with i to 3 (usually 2) of 

 these captured setae in a line with PLs, instead of being displaced 

 caudad for a distance equal to, or greater than, length of those setae ; 

 with antesensillary ridges weak or inapparent, instead of being 

 conspicuous. 



Description of larva. — Body: Ovate, about 366x260 microns in 

 rather engorged holotype. Gnathosoma: as in G. exilis, new species, 

 but palpal formula B/B/NNb. Scutum: Long, broadly and evenly 

 tongue-shaped, 152 x 94 microns in holotype. Anterior margin slightly 

 concave; lateral margins somewhat constricted behind level of SB 

 and at apical third or fourth, otherwise convex; caudally broadly 

 rounded. Punctations uniform in size, each about one-tenth size of 

 setal base; evenly distributed over surface. AL setae fairly stout, 

 plumose ; extending to about base of PL. Posterolateral setae similar 

 in size and shape. Usurped setae somewhat smaller and thinner than 

 true scutals; pinnae less developed; 17 to 22 in number, most of these 

 nonmarginal. Ridges anterior to sensillary bases usually weakly de- 

 veloped, inapparent. Sensillary bases inserted midway between AL 

 and PL. Body setae: Dorsal setae similar to true scutal setae but
