of each side ;it alxmt the middle of the scutum. Posterior to this 

 point and between the broad irJtitc stripes are 4 narrow white stripes 

 extenchno- to the festoons: the inner 2 of the 4 are usually iniited 

 anteriorly with each otlier: posteriorly they are united with each 

 lateral member of the <xroup; each lateral member is connected an- 

 teriorly with the hrooiJ white stripe of each side. The continuity 

 of the white is often bioken by minute punctations and small iri'eg- 

 ular ])atches of brown. In areas where no rust is present the pig- 

 mentation of the ceca is visible as irreaular black lines. Pseudoscu- 

 tum not well tlefined. brown with irregular patches of white rust 

 as mentioned above; cai)itular emargination 200/i, deep by 650/x wide; 

 cervical grooves short, moderately deep depressions, not extending 

 to level of eyes; marginal grooves narrow and shallow, marked by 

 a row of 10 to 14 medium-sized punctures; also a row of punctures

on each lateral margin, and a few scattered ones in the scapular 

 region between the eye and the cervical groove. Over the remainder 

 of the scutum is a conspicuous absence of the deep punctures so char- 

 acteristic in some species of the genus Dennacentor. Eleven well- 

 defined festoons, the outer ones broader than the inner ; the posterior 

 margin of each is of a lighter brown, and each is marked dorsally 

 with irregular patches of white and Avith one to three small punc- 

 tures. Venter hairy, with numerous small and a few scattered me- 

 dium-sized punctures ; the region posterior to and between the coxae 

 of each side much lighter in color tlian coxae and festoons. Genital 

 orifice on level with coxae II ; genital grooves about parallel to the 

 level of coxae IV, Avhere they converge slightly, then diverge sharply 

 and extend to the posterior margin of the body to unite with the 

 groove between festoons 2 and 3; postanal median groove extends 

 to median festoon. Stigmal plates (pi. 1, fig. 2) elliptical with a
