this as the type. In a recent letter M. Simon agrees to this 

 procedure, although he formerly used the name in a different 

 sense. Thorell bases his idea of Maevia upon a species 

 described by C Koch nnder Plexippus. The type, then, is 

 M. vittata Hentz. 



We have three species, vittata H. and trilineata new, which 

 resemble each other closely, from the United States, and 

 (Euophrys) coronigera C K., (which differs from the other- 

 two in the sloping thoracic part), from Guatemala, Trinidad 

 and Cayenne. We take out of this genus calif ornica P., yav- 

 esii Simon, and tenuis, fenestrata and Stolzmanii Tacz. 



Maevia Poultonii, sp. noy. 



PL XXY, fi-s. 15-15b: PI. XXVI, %. 3. 



Medium sized spiders, plainly marked with three bright red 

 lines down the abdomen, between which the color is silvery. 



$. Length 7 mm. 



?. Length 9.5 mm. 



Legs in both sexes 4132, not very unequal, the first and sec- 

 ond a little the stoutest. 



In the male the cephalothorax is covered with white hairs 

 above, and has a white line around the margin. The sides are- 

 rubbed, but seem to have been dark colored. Under alcohol it 

 appears black except on the back of the thoracic part. In the 

 female the general color is light, only the eye-region appearing 

 black under alcohol. When dry the whole cephalothorax is 

 seen to be covered with pale hairs. The abdomen, in both sexes,, 

 is silvery, with three longitudinal, bright red lines. These are 

 continuous in the female, but in the male they are more or less 

 broken by silvery bars, especially those on the sides, which form 

 four or five elongated spots. The f alces are short and vertical, 

 and both face and f alces are dark colored. The legs are yellow 

 and very spiny. 



We have two males and one female from San Antonio, Texas,, 

 sent to U.S by Mr. C. Tyler Townsend.
