ORTIIOPTERA OF INDIANA. 407 



Body robust; front femora a third or more longer than the pro- 

 \notum, with a single spine on lower front carina. Hind femora short 

 and stout; tlie inferior sulcus of average width and depth; hoth 

 carina^, of male armed on apical half with seven to 15 small saw-like 

 teeth; those of female with similar hut smaller scrrulations. Hind 

 tibia' straight, distinctly longer than the femora, the inner calcaria 

 considerably longer than the outer, but shorter tlian the first tarsal 

 joint. Cerci tapering from a rather stout base, a little longer than 

 the femoral breadth. Ovipositor rather slender, two-thirds the 

 length of hind femora, its apical third very slightly arcuate, the tip 

 but little upturned; teeth of the inner valve small and distant from 

 one another. 



Measurements: Male — Length of body, 1G.5 mm.; of pronotum, 

 5.5 mm.; of front femora, 8.5 mm.; of hind femora, 16 nnn.; of hind 

 tibia?, 18.5 mm. Female — Length of body, 1(3 mm.; of pronotum, 

 5.5 mm.; of fore femora, 6.5 mm.; of hind femora, 15.5 nmi.; of hind 

 tibia?, 17 mm.; of ovipositor, 10.5 mm. 



This is another species where the measurements of Indiana speci- 

 mens greatly exceed those given by Mr Scudder in his Monograph. 

 It is not common in the State, being represented in my collection 

 only by specimens from Vigo and Orange counties; those from the 

 former county, taken in September and October, being full grown, 

 while those from Orange County, taken in ]\Iay, are but little more 

 than half as large. 



Aside from these Indiana localities, the species has been recorded 

 only from Maine and N'ew Brunswick. 



Family GRYLLIDiE. 



nie third family of Orthoptera belonging to the sub-order Salta- 

 toria comprises the GrijlVuhe or crickets. From the other Orthopter- 

 ous insects they may be distinguished by having the wing covers 

 flat above and bent abruptly downward at the sides; the tarsi or 

 feet, three jointed, without pads between the claws; the fore coxfe 

 longer than broad. Ocelli or simple eyes are present in the majority 

 of species; while the antennte, like those of the Lociistidm, are long, 

 slender and many jointed. Tlie hearing organ, when present, is, as 

 there, situated on the base of the fore tibise. 



The tympanum or calling organ of the male is also, as in the 

 Locusiida\ located near the base of the dorsal surface of the tegmina, 

 but is wider and broader than in the preceding family, extending 

 across both anal and median areas of the tegmina. The chirps or
