Ceratinella laeta (Camb.) 



Erigona Iceta Cambr., Proc. Zool. Soc. London, 1874. 

 Plate YIII, figure 1. 

 Length 1*6'"'", sliglitly larger than ketabiUs ; both these species are 

 found under leaves and probably live near the ground all the year, 

 not spinning high like ^fissice^js. Color dark brown. The tJiickened 

 spot only on the abdomen of the male. The abdomen of the female 

 is sometimes almost black. Other individuals have a light stripe 

 along the middle of the back with three or four cross stripes. The 

 head is high behind the eyes, especially in the males. The tibia is 

 short and the tibial and tarsal hooks both long. The tube is stout 

 ami black, broken in the middle, where each half has a short tooth.

Ceratinella laetabilis. 



Erigone latahilis Cambridge, Proc. Zool. Soc. London, 1874. 

 Plate VIIT, figure 2. 



Length, r.5'""', a little smaller than 6'. IcBta. Cephalothorax 

 and sternum dark brown, legs dark orange. Thickeneil parts 

 of the abdomen dark orange, brown, thinner parts gray, broken by 

 lighter irregular spots. In the females, where the tliickened circle on 

 the abdoaieu is wanting, the whole back is dai-k gray with lighter 

 patches and thickened spots at the ends of the vertical muscles. 

 The head is slightly elevated behind the eyes, a little more in the 

 male than female. The male has the thickened circle on the abdo- 

 men very hai-d and distinct. The female usually wants it altogetlier. 

 The pal])al organs distinguish this easily from C. la-ta. The tibial 

 hook is short and wide and curved strongly inwai'd. Fig. -lb. The 

 tube is bent sharply at tlie middle as usual, and the outer edge of the 

 basal half projects as a very distinct tooth. Fig. 2a. t 



The females are less easily distinguished from (J. IcBta. They are 

 a little smaller and lighter colored and the epigynuin. Fig. 2(7, has its 

 opening shortei- than the other species.
