I2S 



peculiar, the cartlo is very largely developed, the stipites, 

 as a rule, are very long and pointed, widely foliaceous on 

 their outer margin ; the sagittas short ; it varies, however, 

 in form, and in the sub-genus Lindcnius the stipites lose 

 their foliaceous shape and the sagittoa are long ; in some 

 species the seventh dorsal segment is produced at the sides 

 veatrally, so as to project as two points or processes on 

 the ventral surface of the abdomen; legs variable in form, 

 especially the anterior pair, of which the tibia3 and tarsi 

 are often strangely modified. The genus is an extensive 

 one, and seems to exist nearly over the whole world. 

 The species provision their nests with DqHera and other 

 insects. The larvae spin tough brownish cocoons. They 

 form their burrows in various places ; some in the ground, 

 others in decaying wood, bramble stems, &c.
