This locust was common in some localities, where it was found during warm days 

 when the sun shown brightest, among ferns and other green foliage. The mature 

 males were so lustrous and gem-like as to suggest the generic name Lithoscirtus to the 

 present writer, who had not then recognized Stal's genus Dellia.

The genus Coscineuta belongs to Tropical America north of the equator, where the 

 few species are rather widely distributed, but apparently rare in individuals. Two 

 somewhat distantly related forms belong to our territory. They may be known by the 

 characters mentioned below.

This is a most beautiful and strikingly-marked insect when not preserved in spirits. 

 The blood-red coxse and the regular dark bands on the base of the abdominal segments 

 must certainly render it very conspicuous in life.
