522 FAMILY VII. TETTIGOXIID^E. THE KATYDIDS. 



sect in Ontario, ranging northward about as far as Muskoka and 

 the Bruce Peninsula. It frequents fields, vacant lots and road- 

 sides, which resound at night with the incessant monotonous 

 song. During the summer and autumn * * * I have occasionally 

 heard it stridulating in bright sunshine in the afternoon. It is the 

 most easily approached of all our locustarians while thus engaged 

 and is in fact difficult to find in "any other way, hence the females 

 are but seldom seen. Although it usually perches upon tall weeds, 

 I have occasionally traced its song to a tree or vine, the insect 

 being sometimes stationed at a considerable height." 



Allard (1911) says that in September near Oxford, Mass., 

 cnsiger is a very common species in all upland localities where it 

 "prefers the fresh herbage of cultivated fields and is especially to 

 be looked for in fields of corn. One oftentimes finds a noisy 

 singer perched six or seven feet from the ground on a corn stalk 

 or tassel. One also sometimes meets with it in large colonies 

 among the luxuriant weeds and grasses of the lowlands. Its call 

 notes are intermittent and follow each other rather briskly- 

 tslp-tsip-tsip-tsip. They are rather soft and lisping, recalling to 

 mind the staccato lisps of an OrclicUnniin." 



R. & H. (1915, 385) have placed the Conoceplialus atteiiitatns 

 Scudder (1872, 249) as a synonym of N. ensiger. 



238. NEOCONOCEPHALUS ROBUSTUS (Scudder), 1862, 449. Robust Cone- 

 head. 



Size large, form robust. Pale green, rarely brown; fore and middle 

 legs, hind tibiae and tarsi and under surface greenish-yellow; sides of 

 fastigium and lateral carinag of pronotum yellowish; antennae pale reddish- 

 yellow. Fastigium with under surface immaculate, 06 about as long as oc- 

 ciput, distinctly narrowed from middle to apex, its upper surface convex, 

 tip narrowly rounded (Fig. 169, f.) Pronotum with lateral carinse dis- 

 tinctly divergent, more strongly so in male, hind margins broadly rounded, 

 surface finely punctate; lateral lobes almost as deep as long their lower 

 margin oblique, obtusely angulate; humeral sinus shallow, broadly 

 rounded. Tegmina broader than in allied species, surpassing hind fe- 

 mora about 13 mm. Stridulating field of male large, its main vein heavy. 

 Fore and middle femora either unarmed beneath or with a few small 

 spines. Hind femora long, slender, armed beneath with three to 12 

 rather short spines on each carina. Length of body, $ , 30, $, 31 37; of 

 fastigium, $, 2.73.6, $, 3.13.7; of pronotum, $, 89.9, 9, 7.38.3; 

 of tegmina, $, 4048, $, 4354; of hind femora, $, 2328, $, 2428; 

 of ovipositor, 25 31 mm. (Fig. 175.) 



66 This is true of all the specimens at hand and R. & H. (.1915, 387) say that the ver- 

 tex is always immaculate, but Scudder, in his original description, loc. cit., says of the 

 type: "tubercle of the vertex tipped with black, not extending or but very faintly and 

 narrowly, down the sides."
