cannot be determined. The postcostal vein is thick throughout, but 

 broadens apically ; the tirst and second oblique veins are both per- 

 fectly straight, originating scarcely further apart than the width of 

 the postcostal vein and diverging considerably. From the position in 

 which the wings are preserved (one fore wing almost exactly covering 

 the other, and the two enclosing between them both hind wings, also 

 almost exactly superimposed) the tirst and second discoidal veins of the 

 two fore wings and the two oblique veins of each hind wing form a 

 medley of almost confluent lines, so that it is a little diflicult to deter- 

 mine to which of the four wings and to what part of that wing each of 

 the eight veins belongs ; regarding the veins of the hind wings there 

 may, therefore, be some error in the statement to be made, but there 

 can be little doubt of the position and relation of the veins of the fore 

 wing which appears to lie ui)permost. The cubital vein originates at 

 a distance beyond the base of the second oblique barely greater than 

 the distance at which the latter is placed from the first ; it makes an 

 angle with the postcostal vein of less than forty-five degrees ; is no- 

 where in the least degree sinuous, but is bent very slightly forward at 

 each forking, rather more at its tirst than at its second ; sends off its 

 first branch at slightly less than a millimeter from its base ; forms 

 with it an angle of twenty-five degrees, and at an equal distance farther 

 on emits its second branch at a similar or slightly smaller angle ; both 

 the branches are perfectly straight, and the upper branch of the last 

 fork lies midway between the lower branch and the stigmatic vein ; 

 the latter is similar to that of 6-'. petrormn from the same beds, but is 

 not so strongly curved ; the first branch of the cubital vein also divides 

 equally the space between the second oblique and the lower branch of 

 the last fork of the cubital vein. The oblique veins of the hind wing 

 (see above) originate at no greater distance apart than the first and 

 second oblique veins of the fore wings, are a little less divergent than 

 they, and equally straight. 



Length of fragment of wing, 5""" ; its probable complete length, 

 6™" ; breadth of same, 1.35'"'" ; distance from base of front wing to the 

 origin of the stigmatic vein, 4.1""".

Family FULGORID^E. 



The species of this family which have been found in British Colum- 

 bia are few in number but varied in structure, each belonging to a 

 distinct sub-family, and of considerable interest ; all are very large.
