Bishopp — Some Neiv Xorth American Ixodidsb. 207 



specimen varies more Erom the type than the others herein listed. The 

 greatest width of the basis capituli is 660/* and the width between the 

 centers of the postero-lateral angles is 502/*. The porose areas are rather 

 smaller than in the type and do not reach to the posterior border of the 

 basis capituli. The leg's are longer and stouter than in the type. The 

 stigmal plates measure about 316 m x 27.">/*. 



Haemaphysalis chordeilis Packard. 



In the course of the studies of the life histories of ticks being conducted 

 by the Bureau of Entomology three lots of ticks were collected which con- 

 tain males of this species. In three instances we have reared to adult 

 males, specimens collected as nymphs. The three above mentioned collec- 

 tions which contained males were made by Mr. J. I). Mitchell in Victoria 

 County, Texas. The collections were made on meadow larks on the fol- 

 lowing dates; November 12, 1909 ( 1 c?, 4 $ ), November 25, 1909 (5 <?, 

 4 nymphs. 23 larvae), March 23, 1910 (1 J). 



Since the male of this species has not been described, the following 

 characterization is given: 



Capitulum from 416/* to 488a* long (from tip of palpi to tip of pos- 

 tero-lateral angles of basis capituli); basis capituli from 287/* to .">44 /* 

 wide, amber in color, rectangular, postero-lateral angles short but well 

 defined, center of dorsal surface with a number of punctures; palpi amber 

 in color, length from 258/* to 316/*; first and fourth segments very 

 small; second segment produced laterally and ventrally to form a promi- 

 nent but not acute angle; a few scattered yellowish bristles on palpi; the 

 infra-internal edges bear a number of feather-like bristles; hypostome 

 rather blunt with five rows of moderately small teeth. 



Scutum covers all of dorsum but a narrow marginal strip, light gray in 

 color, shading into amber anteriorly; glaborous, shining rather thickly 

 and coarsely punctured, some specimens showing a small rugose area at 

 antero-lateral angles; fovae nearly black opposite or slightly posterior to 

 fourth pair of legs; cervical grooves deep anteriorly, first converging, 

 then diverging and disappearing posteriorly; postero-median groove dis- 

 tinct, deepest at posterior end; accessory grooves shallow and broad; 

 marginal groove deep, extending from a point opposite the second pair of 

 legs to the fourth festoon. 



Legs yellowish brown, translucent, with numerous light yellow hairs; 

 trochanters I with prominent blade-like process projecting backward; 

 tarsi all tapering rather abruptly to end; coxae slightly darker than legs, 

 with numerous yellow hairs; coxae I, II and III with very short, blunt 

 basal spurs; coxae IV with a rather long, blunt spur. 



Stigmal plates broadly oval, sides nearly parallel for some distance; 

 with a short, broad dorso-posteriad prolongation; size from 358/* long 

 x l's7 /* wide to 373 /* long x 230 /* wide (width includes prolongation); 

 macula small, situated toward antero-internal angle, rather closely cov- 

 ered with many moderately small goblets of nearly uniform size. 



Body ellipsoidal in contour, widest posteriorly; marginal strip of dor-
