variable in size, the largest measuring nearly or quite 0.20 in length. It is of a 
chestnut red, or sometimes yellowish color, with the abdomen commonly blackish 
The thorax is glossy, closely punctured, with two impressed longitudinal lines, which 
are nearly parallel, with their forward ends more deeply impressed. A large white 
spot on the scutel is variable in its size. The abdomen is not glossy. It lias a sub- 
margmal impressed line, and on its hind part two or three faint, longitudinal 
impressed lines are usually perceptible. The knees, and commonly the other joints 
of the legs are marked exteriorly with a small white crescent or a slender ring. 
The ticks of our country which are most similar to this merit to 
be noticed in connection with it. 
One of these, differing in being widest back of the middle and 
tints having an ovate form, and more largely covered with white, this 
color having a tallow-like appearance, of which I have received speci¬ 
mens from Virginia and from the Indian territory west of Arkansas, 
may be named and characterized as follows: 
FrvE-LmED Tick, Ixodes 5 -striatus. Ovate, rust-colored; thorax and scutel tallow 
white with irregular rust-colored spots and punctures; abdomen with punctures and 
five impressed longitudinal lines, the outer one on each side being sub-marginal • 
legs paler, their joints white. Length 0.20. 
Another species, which was received in company with the preced- 
ing, liom Rev. William S. Robertson, Tullehassie, Indian territory, 
I dedicate to its discoverer. It presents the following characters : 
Robertson s Tick, Ixodes Itobertsonii. Oval, punctured, rust-colored, above 
marbled with tallow white on the head, thorax and abdomen, with rust-colored 
punctures; abdomen with a sub-marginal impressed line, between which and the 
edge are deeply impressed, equi-distant, transverse lines with white interstices; 
joints of the legs white. Length 0.16. 
Torturing Tick, Ixodes cruciarius, new species. (Aptera. Acaridie.) 
An oval lead-colored tick, with chestnut-brown head and legs, which sinks its 
head into the skin of man and animals, gorging itself with blood; its wound intol¬ 
erably painful and dangerous. 
Dr. Gideon Turner, of White Creek, N". Y., has presented me with 
a specimen ol a tick with which is connected a history of much inter- 
rest. I regret that a full written statement of this case, which I had 
been somewhat encouraged to expect, has never come to hand. A 
memoiandum which I made from a verbal statement which was given 
to me, is to the following purport: 
It M r as on a morning in July, 1868, that a daughter of Dr. Turner 
was awakened from her sleep by a most excruciating pain in one of 
her limbs. She immediately discovered that this torment was caused 
by an insect which, during her sleep, had almost buried itself in the
