ing Ilyponeura, in possessing two rows of post-costal cellules. M. blacJc- 
burni , p. 238, and oceanicum , p. 239, Hawaiian Islands, spp. nn. Following 
the descriptions of the above are critical notes on all the Hawaiian

into the latest systematic ideas on classification ; p. 240.

See Odonata , ante, p. 263. Observations drawn up chiefly from a species 
of exotic Locustidce ( Meconema ?). Worked out in the same manner as 
the previous paper, and towards the same end, viz., the construction of a 
flying machine, which the author considers [perfectly practicable if due 
regard be taken of the mechanism as existing in insects.
