Labium nearly square ; base rather broader and darker in 

 colour than the top. 



Sternum broad and heart-shaped, and, with the labium, max- 

 illse, and falces, of a yellowish-brown colour. 



Abdomen oviform, hairy, and projecting slightly over the base 

 of the cephalothorax ; upper part and sides very dark brown ; 

 under part and spinners much paler; spinners pale yellowish 

 brown, and placed in a slightly curved row at the end of the 

 abdomen ; the outer ones are longest, and three-jointed, the 

 spinning tubes being placed on the lower surface of the last 

 joint. 



An adult male of this small, plainly-coloured Ac/elena was 

 captured by myself, among copse-wood, at Lyndhurst in the 

 New Forest, at the end of May 1860. 



Family TnERiDiiDiE. Genus Theridion, 



Theridion stictum. 



General colour I'usty yellow, with the cephalothorax and several 

 patches on the abdomen deep red-brown ; two of these patches 

 are fonvards on the upper side, and one on each side : abdomen 

 with four or six red-broivn spots on the upper side in the form 

 of a square or oblong ; it is extremely globular in shape, and 

 projects greatly over the base of the cephalothorax, ivhich, with 

 the sternum, is peculiarly covered with small punctures ; legs 

 short and moderately stout. 



Nearly adult female. — Length ^ of an inch ; length of cepha- 

 lothorax ,7\j, breadth ~j ; breadth of abdomen j\ ; relative length 

 of legs 1," 4, 2, 3. 



Cephalothorax oval, prominent, and compressed on the sides 

 near the eyes; it has the appearance of roughness from nu- 

 merous small punctures, especially along the medial line, hinder 

 part, and towards the lateral margins ; its colour is deep maho- 

 gany-brown (nearly black), clothed thinly with small yellowish 

 hairs. 



Eyes eight, in two rows on the front of the cephalothorax, 

 the foremost row hanging over, as it were, the base of the falces, 

 but considerably above them. The four intermediate eyes form 

 a square ; the front pair of the four are placed on a protuber- 

 ance, and are rather the largest and the darkest-coloured of the 

 eight. The eyes of the side pairs are contiguous and placed on 

 a tubercle. 



Legs short, stouter than those of species of this genus in 

 general, furnished with fine bristly hairs, chiefly placed in rows 

 along the dijBFerent joints. Colour reddish yellow, of a brighter
