katydid is an example, and which stridulate by rubbing together 

 the bases of the fore wings, provided for the purpose with a 

 sort of tambourine, a tense thin membrane stiffened by cross 

 ribs ; all these songsters are males, the wings of the females 

 being unprovided with the apparatus necessary to produce a 

 sound. The short-horned grasshoppers stridulate but feebly, 

 and generally by scraping their fore wings with the hind 

 thighs — fiddle fashion. 



Very rarely — it has been recorded less than a dozen times — 

 one of these long-horned grasshoppers is found of a violet or 

 pink color instead of green or brown. It occurs only as a rare 

 " sport." A pair of these, belonging to the species known as 

 Amblycorypha oblongifolia, are figured on our plate, painted 

 from life, as they were feeding on the flowers of golden rod, 

 which they devour with great zest. 



The female with its sabre-like ovipositor is shown above, the 

 male below. The female is of a pale coral red verging on ma- 

 genta, the abdomen a shade paler, while the male is of an 

 orange red. The tegmina or fore wings of the female are of a 

 very clear color, with scarcely a single fleck of brown, while 

 those of the male are much dotted with brown (at least as com- 

 pared with what we ordinarily find in this genus) and flecked 

 longitudinally with yellow, while the stridulating field, the 

 tambourine, is almost entirely dull brown, and an obscure 

 patch of the same color, more distinct on one wing than on the 

 other, appears beyond the middle. In both, the palpi are of the 

 color of the body, but the eyes are green and the antennae 

 luteous, as in normal examples. 



This pair of pink grasshoppers was captured at Woods Holl, 

 Mass., at the end of August, 1886, and other specimens were 

 taken during the same month, one so early as the ninth of 

 August. The first example of the sort that I ever saw was 

 a female of another species of the same genus, Aniblycorpyha 

 rotundifolia , taken on Sharp Mt., Pennsylvania, at the end of 

 August, 1878, and sent me by the late Dr. Joseph I^eidy. 

 Riley, however, records a pink specimen of A. oblongifolia in 

 his Sixth Missouri Report (p. 169), and Johnson speaks of 

 another in Science for 1889, p. 32.
