This is the only species of the genus known to occur in the eastern 

 United States, and is the most brightly colored of all our native crickets. 

 In the living specimen the head and thorax are crimson, the wing covers a 

 shining pitch black, while the thick hind femora are almost transparent but 

 become white in alcohol. The wing covers reach the end of the abdomen, 

 and the wings are almost as long. A single female specimen was taken on 

 September 6th, from a leaf of the button bush, Cephalanthus occidentalis, L., 

 near the border of a large pond in Vigo county. When discovered it was 

 motionless, but was vibrating its large maxillary palpi in a very rapid and 

 curious manner. It is a southern species but has been recorded from New 

 York and Illinois, and probably occurs in low wet woods throughout the 

 southern half of this state. According to T^hler, it is found most frequent- 

 ly " amongst the grass and low bushes near ditches where it jumps about 

 with great rapidity.'' 



Measurements: Length of body, S.5 mm.; of ovipositor, 3.5 mm.; of pos- 

 terior femora, 6 mm.; of antennte, 18 mm. 



VII. Orociiaris, Uhler (1864). 

 The members of this genus have the head slightly narrower than the 

 base of the pronotum; the maxillary palpi with the third segment longest, 

 cylindrical ; the apical one a little longer than the one preceding, enlarged 

 gradually from the base, obliquely truncate. Both wing covers and wings 

 are longer than the abdomen. The posterior femora are less thickened 

 and the body less robust, longer, and flatter, than in the preceding or the 

 following genus.

 General color, after immersion in alcohol, dull brownish yellow, the 

 male the lighter. A dark brown stripe reaches from the eye along the side 

 of head and prothorax to posterior border of pronotum. The wing covers 

 each with a small brown spot at base ; those of the female with many cross 

 veinlets which are darker than those running lengthwise, giving the dor- 

 sal field a checkered appearance. In the male the vein separating the dor- 

 sal field of the wing cover from the lateral is yellow ; in the female the 

 yellow is broken by a number of oblong dark spots. All the femora are 

 rather thickly marked with small, dark spots; those on the posterior pair
