CHAPTER. Vaikt 
COMPOSITE SNARES AND SECTORAL ORBS. 
Ue 
In the following chapter I have placed the spinningwork of two groups 
of Orbweayers that appear to me, in spite of some marked differences, to 
have many points in common, namely, those which habitually make a 
composite snare and those which spin an orbweb, lacking one sector. Com- 
posite snares combine the round web of Orbweavers with the netted maze 
of lines which marks the typical Retitelarian. Two spiders which most 
prominently associate with their 
own snare that of the Lineweayers 
are Epeira labyrinthea and E. tri- 
aranea. Of these two, the habit 
is most permanently fixed in the 
former, which is rarely, 
if ever, without its maze,

Triaranea’s orb is habitually sec- 
toral, Labyrinthea’s snare inclines 
to the orbicular, but, as will be 
presently shown, appears to be a 
transition form between the orbic- 
ular and sectoral. In the meth- 
ods on which it is constructed it 
properly is grouped with the sec- 
toral orbmakers. 
The web of the Labyrinth spi- 
der is perhaps the most remark- 
able example of the composite
