Extreme and average rneasuremenls of Nova Scotian specimens. — As 

 compared with various forms of American Gryllus, the males and females of 

 our Nova Scotian variant varj^ in size from very small to medium, and average 

 small in both sexes. The variation in size is considerably greater, however, 

 in females than in males. — Males (8 specimens): length, 15.0-21.1 ram. (ave- 

 rage 18.5 mm.); pronotum, length, 3.0-3.5 (average, 3.29); pronotum, width, 

 5.0-5.6 (average, 5.1); abdomen from hind margin of pronotum, 10.0-15.7 

 (average, 12.4); wing-covers, 8.8-11.0 (average, 9.94); wing-covers from 5.6 

 mm. shorter than end of abdomen, to 1.0 mm. longer than end of abdomen 

 (average, 2.8 shorter); wing-covers cover from 6/lOths to 1 1/lOth of the ab- 

 domen (average, 8/lOths); hind femora, 9.4-10.7 (average, 10.04); hind tibiae, 

 7.0-8.3 (average,7.5); anal bristles, 5.5-7.0 (inlands). — Fema/es( 17 specimens): 

 length, 14.75-23.7 mm. (average, 19.27 mm.); head, length, 2.7-3.0 (average, 

 2.87); head, width, 4.1-5.0 (average, 4.71, in a-d); pronotum, length, 3.0- 

 4.0 (average, 3.55); pronotum, width, 4.6-6.0 (average, 5.32); abdomen from 

 hind-margin of pronotum, 9.6-17.0 (average, 13.72); wing-covers, 6.95-10.5 

 (average, 8.86); wing-covers from 2.15 mm. to 7.2 mm. shorter than end of 

 abdomen (average, 4.86 mm.); wing-covers cover from 57/lOOths to 77/lOOths 

 of abdomen (average, 65/lOOths or 2/3rds); hind femora, length, 9.2-11.5 

 (average, 10.3); hind femora, greatest width, about 3.3; hind tibiae, 

 7.0-9.0 (average, 7.73); ovipositor, 12.2-15.2 (average, 13.69); hind femora 

 contained in length of ovipositor, 1.17-1.47 times (average, 1.32 times); 

 antennae, 33 mm. (in female e) and 28.5 (in female /). In all specimens, 

 male and female, the hind-wings are shorter than the wing-covers; the hind- 

 wings being 8.0 mm. long in one female (e) which was measured, in which 

 the wing-covers were 10.0 mm. None of the males have a ^-shaped 

 notch between the ends of the wing-covers; but in the females, 9 have such 

 a notch more or less developed, while 8 are more or less without the notch, 

 although in this feature complete intergradation is seen. 



The following diagram illustrates graphically the relative length of 

 the ovipositor as compared with that of the hind femur in twelve Nova 

 Scotian females, about which such data are available, and makes clearer the 

 range of departure from the normal proportions of those members as found 

 in specimens in this province. It will be seen that specimens b, q and / ap- 

 proach nearest to the normal or average line, while the maximum departures 

 are found in specimen a which exhibits the relative longest ovipositor, and in 

 g which exhibits the relative shortest ovipositor as compared with the femur. 

 The longest ovipositor, apart from comparisons with the femur, is actually 

 found in specimen /, and the shortest one in j; while the longest femur is in
