ART. 8 CHIGGEB MITES OF THE NEW WORLD — EWING 13 



seven specimens taken from three young coatis {Nasua naHca pana- 

 mensis), collected at the same place by the same person. 



TROMBICULA CERVULICOLA, new species 

 Plate 1 , Figure 3 



Palpi stout, not angulate ; first seta strongly pectinate, subplumose ; 

 second seta with three to four very long barbs; third seta with a 

 few shorter barbs. Palpal claw tricleft, short, strongly curved; 

 inner prong longest, outer shortest, and middle intermediate. Dorsal 

 plate broader than long, front margin almost straight, posterior 

 margin broadly and outwardly rounded; anterior setae subequal, 

 shorter than the two postero-lateral setae. Pseudostigmata situated 

 slightly behind the middle of the dorsal plate and about three times 

 the diameter of each from each other; almost contiguous with the 

 posterior boundary of each is a short, straight, diagonal slit; pseudo- 

 stigmatic organs very long and slender, with about four or five barbs 

 on the distal half of each. Anterior eyes well developed, each situ- 

 ated a little more than its diameter from the margin of the dorsal 

 plate; posterior eyes vestigial, corneas lacking. About 26 dorsal 

 setae present, not arranged into definite rows. Legs rather long, 

 posterior pair longest; tarsus I with dorsal spine, spinelike and 

 situated almost twice its length from the base of the segment; sub- 

 apical seta of tarsus I spinelike. 



Length of slightly engorged larva, 0.31 mm.; width, 0.22 mm. 



Type host. — Barking deer [Ceriiulus mirews). 



Type locality. — Mulctesar, Kumaun, India. 



Type .§??*<?e.— U.S.N.M. No. 1020. 



Three specimens at hand, all taken from type host, at type locality, 

 March, 1930, by Mr. Cooper. This species is near acuscutellaris 

 Walch, but the dorsal shield is not angulate posteriorly, and the 

 pseudostigmatic organs have fewer barbs. 



TROMBICULA PIERCEI, new species 



Plate 1, Figure 4 



Palpi slender, not angulate laterally ; first, second, and third setae 

 long and simple ; claw curved and very slender, tricleft distally with 

 middle prong largest and lateral prongs subequal ; thumb very short, 

 subterminal. Chelicerae each with upper and lower tooth prominent. 

 Dorsal shield indistinct but broader than long; median seta more 

 slender than the others; postero-lateral setae longer than antero-lat- 

 eral. Pseudostigmata in front of line drawn between the two postero- 

 lateral setae and situated a little more than their diameter apart; 

 pseudostigmatic organs very long, almost straight, and with many
