Ticks. A monograph of the Ixodoidea, G. H. F. Nxjttall and C. Warbur- 

 TON (Cambridge, 1908, pp. X-\-104+35, pis. 3, figs. 114)- — This worli on the 

 Argasidfe is part 1 of a monograph of the Ixodoidea, now in preparation. Prac- 

 tically all that has been published on the subject is said to haAe received ade- 

 quate consideration. In the authors' opinion the genus Argas comprises 6 

 well-established species, while 4 others are doubtful. Argas miniatus is made 

 a synonym of A. persicus. The genus Ornithodoros is represented by 11 well 

 defined and 3 doubtful species. A complete synonymy and iconography are 

 given for each species. 



Both authors are responsible for the systematic portion, while the biological 

 section was prepared by the senior author. W. F. Cooper and L. E. Robinson 

 assisted in collating the literature on the subject. In the text the Harvard sys- 

 tem of references is adopted, the year and page of the authors' papers being 

 added after their names. A bibliography of about 300 titles printed on one side 

 of thin paper, suitable to cut and paste upon index cards, is appended. Many 

 text figures and plates accompany the work.

 10 (190S), No. 3-4, pp. 170-173, figs. 6). — Dermacentor modestus from a horse 

 at Mountain Home, Idaho, and Prescott and Olympia, Wash.; Aponomma 

 inornata from a dog at Corpus Christi, and a rabbit at Victoria, Tex.; and 

 Ixodes texanus from a raccoon in Live Oak County, Tex., are described as new. 



Some host relations of ticks, W. A. Hooker (Jour. Econ. Ent., 2 (1909), 

 No. 3, pp. 251-257). — Forty-one species of ticks representing 10 genera are said 

 to occur in the United States and Alaska. Amhlyomma dissimile, a Mexican 

 species, is reported to have been collected from iguanas at Brownsville, Tex. 

 The new species Aponomma inornata which has been collected from the dog and 

 rabbit in Texas Ls the first representative of this genus discovered in the United 

 States. In the larval stage Amhlyomma tuberculatum has been found to attach 

 to mammals and birds. The nymphs are commonly found on the gopher tortoise 

 and were experimentally engorged upon a bovine, while the adults apparently 

 attach to cold-blooded animals only. Other si)ecies of which the host relations 

 are noted are Amhlyomma americanum, Hwmaphysalis leporis-palustris, H. 

 chordeilis, Ixodes scapularis, I. cookei, I. ricinus, Dermacentor venustus, D. 

 variahilis, and D. marginatus.
