of the genus Haemaphy satis of the Ixodidae.

Gapitulum : base rectangular, with slightly convex sides, and 
broad blunt cornua, coarsely punctate dorsally. Palps only slightly 
salient, the external angle of article 2 fairly sharp, its inner border 
has, dorsally, an inward projection at its distal end. No distinct 
dorsal spines but the posterior border of article 3 sharply angular 
c? and ? spiracles. 
capitulum and scutum, 
in the middle. Article 2 is sharply angular ventrally, and there 
is a short retrograde ventral spine on article 3. Hypostome 4/4. 
Legs : a short sharp spur on coxa 1, a very slight spur near 
the middle of the posterior border of coxae 2 and 3, a very short 
spur at the inner angle of coxa 4. Tarsi relatively short and 
somewhat humped. 
Female. Scutum nearly circular, bright yellow, coarsely pitted. 
Cervical grooves shallow, concave externally. 
Capitulum-. base broader and shorter than in the </, with 
very slight cornua, sides somewhat convex. Porose areas large, 
oval, far apart, converging anteriorly. Palps longer and narrower 
than in the f ; article 2 with sharper external angle, its inner 
dorsal contour like that of the </. Spiracle round, with blunt 
dorsal protuberance, yellow or white. 
Legs : coxae as in the f. Tarsi 4 tapering gradually, the 
distal pseudo-articulation rather long. 
The Nymphs differ very little from the females except in the 
absence of vulva and of porose areas, and the small size of the 
spiracle. They have the same yellow scutum and their palps 
present similar characteristics. 
N.B. Thorell’s excellent figures leave no doubt as to the 
identity of this species, and shew clearly various characteristics 
not mentioned in his description, such as the “ridge-like tracts,” 
the short indefinite lateral grooves, and the inward dorsal pro- 
jection of article 2 of the palps mentioned above. If Canestrini
