Sub-family Phaneropterlnae. 



To this sub-family belong our largest locustidae which are commonly known as 

 "Katydids." These are the most arboreal of all the Locustidae and are solitary in 

 habit, and while they may be present in fairly large numbers they are seldom noticed. As 

 a rule they are nocturnal, but their call may often be heard during the daytime and one 

 may stand close to a very small shrub for a considerable length of time listening to their 

 music, but fail to see the musician, so well does their color harmonize with their sur- 

 roundings. The males of each species have their own particular call. This sub-family 

 is represented in Nova Scotia by only one genus, which is characterized as follows: 



Scudderia (Stal. 1873). 



Insects of medium size. Head oval; vertex compressed; fastigium acuminate, 

 slightly deflected and very narrow. Prosternum without spines. Fore and middle fe- 

 mora unarmed beneath, hind femora very long and slender. Wing covers long, broader 

 than length of pronotum and rounded at distal end. Hind wings strong and exceeding 

 the tegmina in length. Ovipositor short, broad and strongly curved upward, the distal 

 third finely crenate on both margins. The males are readily distinguished by having 

 both anal plates projected into long curved processes. The supra-anal plate is curved 

 downwards and is notched at the distal end. The sub-anal plate is curved upward and is 

 also notched. These processes are used as characters for determining species. 



So far the writer has only taken two species in the province. A third species has 

 been reported by Mr. Harry Piers, of Halifax. The writer has not seen Mr. Piers' 

 specimens, but a description of the species is given from specimens kindly given me by 

 Mr. W. T. Davis, of Staten Island, New York. These species can be separated by the 

 following key; 



Key to Species of Scudderia. 



A. Supra-anal spine furcate with the lateral processes sub-triangular not broadly 

 rounded. Tegmina much deeper than body pistillata 



B. Supra-anal spine with lateral processes broadly rounded. Tegmina narrow 

 of about equal width of body ■ cuivicauda botealis 



C. Supra-anal spine with lateral processes very much swollen, broadest at their 

 bases. Tegmina narrow 7 fincata juicata. 



Scudderia pistillata Brunner > Fig. I. 



This is our largest Katydid and is chiefly found in trees and shrubs, sometimes in 

 long grass. 



General color dull green with the head somewhat lighter in shade. Dorsal surface 

 of pronotum and legs may be tinged with light brown. 



Head small, face almost vertical with the front and genae rounded. The vertex 

 slightly rou*nded and ending in almost a point between the bases of the antennae where 

 it meets the point of the frontal costa. Antennae long, slender, many jointed; eyes small 

 glabrous, hemispherical; pronotum with front margin truncate, hind margin broadly 

 rounded, disk flat; prozona narrower than metazona and showing a faint groove in 

 place of the median carina; principal sulcus faint; lateral carina slightly rounded, lateral 

 lobes slightly longer than deep, lower margin broadly rounded. Tegmina leaf-like, 

 longitudinal veins prominent, distal end broadly rounded. Stridulating field large, 

 arcuate vein prominent, under side with minute file-like teeth. Front coxa bears a 

 small slender spine on the outer surface. Hind legs long and very slender, seldom used 

 for leaping. Several minute hairs are present on all legs and all tibia are armed with
