by the structure of the palpal organs; in colour and markings, however, the two species 
resemble each other very closely. . 
An adult male was found in the summer of 1867, running on iron railings at Bloxworth.

The female only of this species is described in Mr. Blackwall's work on British and 
Irish Spiders; it will not be amiss, therefore, to give here one or two leading charac- 
teristics of the male, which I have discovered in abundance since the publication of that 
work. 
The male is like the female in colours and markings, though perhaps in general less 
distinctly marked ; there is, however, considerable variation in the distinctness of pattern 
in both sexes. Some examples have the upperside of the abdomen almost wholly suffused 
with white cretaceous-looking blotches, with an elongate subtriangular brown-black 
marking forwards, followed by a longitudinal series of angular bars or chevrons quite to 
the spinners; other examples have some yellowish and red-brown colour mixed with the 
white. : 
. The cubital and radial joints of the palpi are short, the cubital being rather the longest, 
strongest, and produced at its fore extremity on the upperside into a short, pointed, 
curved, reddish spine. The digital joint is large, and of a broad, pointed oval form. The 
palpal organs are well developed, but not very complex; a black, coiled, filiform spine 
surrounds them; and its point (or the point of some other portion of the palpal organs) 
projects backwards over the fore extremity of the radial joint, rather on the outer side; 
at first sight this projecting point appears to issue from the radial joint, with which it is 
in exceedingly close contact. 5 
This species is abundant in Hampshire and Dorsetshire. I have found it most nume- 
rousin May and June on furze bushes, among the shoots of which it spins an irregular 
web. The females have calamistra on the metatarsi of the hinder pair of legs; but the 
males (as noticed above in reference to Ciniflo Mengii) have none; but both sexes have 
the extra spinners in front of the ordinary ones. 
The adult male of Ciniflo humilis may be distinguished from C. Mengii by the cha- 
racters detailed in the description given above of the latter species, and from C. puta 
by both the form of the palpi and the colours and pattern on the abdomen.
