10 COXTRIBUTIONS TO CANADIAN PALEONTOLOGY. 



Sub-famUy FULGOEIN^. 



This group is much better represented in American than European 

 tertiaries, and it is only on this continent that we find the lantern-flies 

 proper, or those genera which have a strongly projecting frontal pro- 

 cess, usually recurved. These are represented at Florissant, Colorado, 

 by two species of Nyctophylax, and in British Columbia we find a 

 species of Enchophora or allied form. 



Enchophoea Spinola. 



The living members of this genus are all inhabitants of tropical 

 South America, notably Brazil, and form one of the group of so-called 

 lantern-flies of the tropics, the projecting frontal horn being at least 

 in some instances presumably luminiferous. The species here brought 

 to view, though very imperfect, plainly belongs in this near vicinity, 

 and was larger than all but the largest of the existing lantern flies. 



Enchophora sp. 



PL I, fig. 5. 



A very characteristic but very small fragment of a large insect is 

 particularly interesting as it has an unmistakeable tropical aspect. It 

 is simply the cephalic process of one of the Pulgorinae, and is ap- 

 parently to be referred to this genus or its near vicinity. It is large 

 and stout, and though no other part of the head is preserved, it is pretty 

 certainly the entire process, showing it to have been roundly bent 

 upward at a right angle a little before the middle, with the faintest sign 

 of enlargement apically ; the tip is well and regularly rounded, and 

 shows no sign whatever of being trilobed, so that it probably belongs 

 to a distinct genus. The insect bearing it must have been a large one, 

 probably not less than four centimetres long.

Sub-family DELPHACIN.a;. 



Fossil species of this group are but two or three in number and all 

 have been referred to existing genera excepting that described below, 

 which appears to be a very extraordinary insect with unusually aber- 

 rant venation in the tegmina.
