H. cinnabaidna 377 



in May, where it killed off 40 out of 46 young turkeys before the ticks 

 were finally destroyed by hand-picking. Many immature and adult 

 ticks, the latter to the number of 70-80 per bird, were found attached 

 chiefly to the birds' necks; the ticks were determined by Banks. 

 Hooker, Bishopp and Wood (1912, pp. 97-102) state that the tick 

 chiefly infests ground-inhabiting birds, the immature stages usually 

 occurring on the top of the birds' heads, around the eyes and ears, 

 and at times beneath the bill. It is often found together with 

 H. leporis-palustris. Other hosts are the meadow-lark, jackdaw, red- 

 winged blackbird, marsh-haivk. In Texas the meadow-lark is chiefly 

 infested ; Hunter (vi. 1909, p. 252), with J. D. Mitchell, found what 

 appeared to be the o and X on a quail {Colinus virginianus) at 

 Brownsville, in the autumn of 1907, and o and L (also L skins) 

 were found on the heads of quails and laiks (Sturnella magna neglecta) 

 at D'Hannis (an adult which developed from a replete O was identified 

 as^. chordeilis by N. Banks). From 12 quails dropped into bags after 

 being shot in Victoria County in December, 1907, Mitchell reports that 

 over 500 ticks were collected: "that there were 1000 ticks upon the 12 

 quail would be a conservative estimate." The author adds that some 

 of these ticks may have been H. lepoHs-palustris. We have received 

 specimens (N. 2833, 2834) from the meadoiu-lark {Sturnella m.agna), 

 Victoria, Texas, 1909, presented by Mr F. C. Bishopp. Bishopp 

 (VI. 1911, p. 208) states that J. D. Mitchell found the tick three 

 times on meadow-larks in Victoria County, Texas : 1 </ on 23. ill. 

 1910; 1 (/ 4 ? on 12. xi. 1911; 5 cT 4 o 23 /. on 25. xi. 1911. 

 In the autumn, nearly all the ground-feeding birds are infested with 

 the o and L as observed by Mitchell in Victoria County, and at Grand 

 Cane, Louisiana and in Quincy and Hawthorne, Florida. Hooker 

 (1909, p. 423) states that the tick occurs also in the State of New 

 York; we have received (N. 2737) 1 ? from ruffed grouse, Catskill 

 Mts., viii. 1909, presented by Dr L. O. Howard. 



As previously stated, Koch's type % came from Brazil. 



Remarks regarding H. cinnabarina, " H. punctata" 

 and " H. chordeilis." 



It was only after having described and drawn the forms kno\Aai 

 commonly as H. punctata in the Old World and H. chordeilis in the 

 New that we became convinced that their differences were merely 

 varietal. This conclusion, together with the undoubted priority of the
