Nos. Mygale fasciata (/i'(?r//).— 5. Sketch, natural size ; 6. Specimen (o).

 contrast between the white bands which cross the legs and the rest 

 of the colour of the insect. The colour is produced by a thick 

 felt of white hairs.

of do. 



This specimen was taken in the dry country of the Eastern 

 Andes, lying on the western side of the Pampas between Mendoza 

 and San Juan, where it is dreaded as extremely venomous. 



Mygale versicolor (A'^r/^). — 9. Specimen from Brazil ; 10. Sketch of ditto, 

 natural size. 



The name versicolor is not well chosen, for there is no great 

 variation in the colour, it only being black with tawny hairs. In 

 addition to its biting powers, its hairs, which readily come off and 

 adhere to the skin, may give annoyance.
