some European s[)eciiiiens the abdomen is almost black with ])airs of 

 small yellowish spots. The eyes are all nearly the same size, the 

 front middle pair slightly larger and farther forward than the others. 

 The epigynum is very different from the other species. 



Steatoda triangulosa (Walck) Thor., Syn. European Spiders. 



Theridion serpentinum Hentz. 



Teutana triangulosa Simon, Arach. de France, vol. vi, pi. 3, fig. 6. 



Female 4'"™ long. Legs longer and more slender than in H. boreale. 

 First pair twice as long as the body. Thora.x; orange-brown, slightly 

 rough in females and with short ridges at the base of the haii'S in 

 males, as in otlier species. The front middle eyes are black and not 

 larger than the others. The legs are light yellow with slightly 

 darker rings at the ends of the joints. There are thickened brown 

 spots at the base of the hairs all over the body. The abdomen is 

 light grayish yellow with two irregular brown stripes nearly broken 

 up into spots, sometimes connected witli each other, and with 

 brown markings on the sides. In the engraving of Ilentz's figure 

 these markings are much more serpentine than in the original paint- 

 ing, where they have a much more natural shape. The epigynum 

 has a triangular opening behind which is a thick ridge. The 

 palpi of the male are as long as the femur of the second legs. The 

 tarsus is pointed at the tip and the palpal organ is shaped much as in 

 the other species. 



I have found this species at New Haven, Conn., in the museum, 

 where it even lives in the glass cases. Mr. Marx has found it in 

 Washington. Hentz had it from Georgia.

This is much like ISteatoda, but the body is more flattened, like 

 Drassidce. The abdomen is flat and widest behind the middle. The 

 cephalothorax is long and narrowed in front. The eyes are small and 

 near together, the hind middle pair larger than the others. The 

 usual pattern of marking in Steatoda is entirely wanting in this 

 genus ; the colors are dark with bright white or yellow spots on the 

 abdomen. The feet of the male are armed with strong teeth on tlie 

 under side. Fig. Qb. These spiders are said to make a noise by rub- 

 bing the abdomen and 'thorax together near the stem, but I have 

 never heard it in this or any other species.
