Plate 36. 



The figures on this plate are from rapid pencil-sketches drawn from Nature out in the field. They 

 represent the various types of nests made by Embia major, and are rather smaller than natural 

 size. The nest numbers refer to those enumerated in the table on p. 188. 



Fig. 1. The simplest form of nest, consisting of a single tunnel and no underground chamber. 

 Nest no. 6. 



2. A complex type of nest, containing two underground chambers. The total length of this nest 



was 1 foot 4 inches. Nest no. 47. 



3. A relatively large nest of simple construction, measuring 11£ inches in length and 5^ inches in 



breadth. Nest no. 20. 



4. A small nest without an underground chamber. Nest no. 26. 



5. A very usual type of small nest. Nest no. 39. 



6. A simple branched nest with no underground chamber. Nest no. 35. 



7. A simple "looped" nest with underground chamber. Nest no. 29. 



8. A small much branched nest without an underground chamber. Nest no. 85. 



9. A small branched nest with underground chamber. Nest no. 110. 



10. A relatively complex type of nest, containing a long underground chamber lined with silk and 

 provided with two entrances.
