ORTIIOPTERA OF NOVA SCOTIA. — PIEltS. 255 



area, the anterior mark being 3 mm. behind the vertex and the posterior one 

 A]/2 mm.; elsewhere on pronotum are small, ob.scure, blackish dots; and on 

 upper outer side of hind femora are three obscure, blackish diagonal bands. 

 (The colour and markings, ixs in other related species, are subject to con- 

 siderable variation.) 



Measurements. — Nova Scotian specimen. Female: body, 8.25 mm.; 

 greatest depth of body, 3.4 mm.; antennae, 2.7 mm.; width of vertex, .8 mm.; 

 length of pronotum, 8.7 mm.; anterior width of pronotum, 2.0 mm.; greatest 

 width at shoulders, 3.7mm.; greatest width of disk, 2.7 mm.; hind femora 5.5 

 mm.; width of hind femora, 2.1 mm.; liind tibiae, 4.2 mm.; ovipositor, 1.0 mm. 



Range. — Eastern United States and southeastern Canada: Nova Scotia, 

 Toronto (Ont.), Maine, and south through New Eng. (common locally), to 

 New Jers. and North Carol, at least. 



Occurrence in Nova Scotia. — This very small and incon- 

 spicuous species, a hump-backed midget and the smallest 

 Orthopteran found in Nova Scotia, was not reported in my 

 paper of 1896. The only specimen so far taken about Halifax 

 and the first collected in the province, is a female which I 

 obtained on a sunny, stony path, alongside of the seashore, 

 on the .southern side of Dead Man's Island Cove, close to 

 Melville Island, at the head of the North West Arm, near 

 Halifax, on 7 August, 1897. As it is the only specimen I 

 have taken, it is doubtless rare in this locality, although 

 it may be less scarce in some particular localities. About 

 Truro, Col. Co., it is rather common, and C. B. Gooderham 

 has a number of specimens, taken by himself at that place, 

 on5and31July, and 20 Aug., 1913; 5 July, 1914; and 22 June, 

 1915; and in the Agricultural College is one also taken at 

 Truro on 18 July, 1913. Mr. Gooderham has observed it 

 as early as 15 April, 1917, just as the grass was beginning 

 to sprout, and he took five specimens on 22 April of that 

 year. He reports it as apparently very abundant at Truro 

 during that spring. As this species, as well as other members 

 of the subfamily of Grouse Locusts, hibernates as a perfect 

 insect, it may be expected to occur from April until autumn. 

 So far it has only been reported from Halifax and Colchester 

 counties. 



The Halifax and Truro specimens are all of the abbre- 

 viated form, N. crisiatus cristatus, with the pronotum extend- 

 ing no further backward than about the end of the femora.
