TWO NEW ORTHOPTERA FROM INDIANA. 



BV \V. S. BLATCHLEY, TERRE HAUTE, INDIANA. 



LocusTiDAE — XiPHiDiUM. Scrville. 

 Xiphidium Saidderi, nov. sp. 



Female. — Front and sides of head and body dark reddish-brown ; 

 vertex, disk of pronotum and tegmina greenish-brown in life, (dull yeiiow 

 after immersion in alcohol). A dark reddish-brown stripe extends from 

 the front extremity of the fastigium to the posterior border of pronotum, 

 and contrasts strongly with the general colour of vertex and disk of 

 pronotum. Femora greenish-brown punctate with many dark brown 

 impressions on their upper surface ; the tibiae darker. Antennae with 

 the basal third reddish, the remainder fuscous. 



The apex between the eyes rather broad, with the sides rounded ; the 

 cone projecting strongly upward and forward and much more prominent, 

 though narrower, than in X. strictum, Scudder. 



The tegmina cover two-thirds of abdomen : the wings are shorter, 

 reaching to middle of abdomen. Ovipositor of excessive length, almost 

 twice as long as body ; slender, and nearly straight until near the apex, 

 where it is curved slightly upward. The posterior femora and tibiae are 

 also longer and more slender than is usual with members of the genus. 



Measurements: $, length of body, i8 mm.; of antenna, 53 mm.: of 

 tegmina, 9.5 mm.; of wings, 7 mm.; of posterior femora, 16 mm.; of 

 posterior tibiae, 16 mm.; of ovipositor, 30 mm. 



A dozen or more females of this striking species were taken from the 

 margins of a large pond in Vigo County, Ind., on October nth, 1891. 

 Although in company with Xiphidium strictum, Scudder, and X. brevipenne, 

 Scudder, yet it was at once noticeable on account of its dark glossy- 

 brown colour and exceedingly long ovipositor. Careful search was made 

 for the males, both then and two weeks later, when the pond was again 

 visited, but none were found, and on the latter visit but one female was 

 seen. Those taken were on the stems of the partially fallen rushes and 

 sedges which filled the margins of the pond. When disturbed they gave 

 two or three enormous leaps, and then moving rapidly for some little 

 distance would endeavor to hide beneath the mass of fallen vegetation. 



Since the above was in MSS., Mr. S. H. Scudder, in whose honour 

 the species is named, and tQ whom specimen.'? were sent, suggests that
