Arachnida. 7953 



are fully developed at the end of May and beginning of June, 

 are reddish brown. 



I captured adult males of this species at the end of April, 1861, at 

 the bases of large trees on the lawn of Bloxworth Rectory, Dorset. 

 Its habitat appears to be in the crevices where the turf and the trunk 

 of the tiee meet, among bits of dead bark, leaves and grass. The ujale 

 is rather more active than many species of Thoraisi, but the female is 

 very sluggish. I found in the same places females adult throughout 

 the summer, and immature specimens of both sexes in Noveniber. 

 This species is closely allied to Thomisus trux, but may readily be 

 distinguished, not only by its colour and markings, but especially by 

 the long, pointed, nearly straight, black spine issuing from the outer 

 projection on the radial joint of the palpi. 



Family Drassid.e. 

 Clubiona assimilata. 



Cephalothorax dull yellow, tinged in front with red, behind with 

 green. Abdomen red-brown, thickly freckled with miuute paler 

 spots and thinly clothed with hoary hairs. A dark red-brown 

 fusiform band, palest down the middle, reaches a third of the 

 length from the cephalothorax ; this band has two oblique, oval, 

 yellowish red spots on each side, and is followed towards the 

 spinners by some obscure, pale, transverse, curved lines. Eyes 

 very nearly equal in size, and those of the front row equidistant 

 from each other. Digital joint of palpi of moderate size. Palpal 

 organs simple in structure, but well developed ; they have a 

 strong spine curving obliquely over them, from their base on the 

 outer side over to the inner side, thence underneath and round 

 their extremity, coming up and projecting on the outer side 

 again. In contact with the point of this spine is some semi- 

 transparent membrane. 



Adult male. Length, 1-fifth of an inch. Length of cephalotho- 

 rax, ] -tenth. Breadth, 1-twelfth, Relative length of legs, 

 4, 1, 2, 3. 



Cephalothorax oval, slightly compressed laterally in front ; frontal 

 margin curved, and but very slightly depressed from the centre 

 to the eyes; it has a narrow indentation in the medial line. 

 Colour dull yellow, with a red tinge in front and a green tinge 

 behind.
