men ; this capitate process bears near the end a pair of broad, flattened lateral proc- 

 esses ; female without an exerted ovipositor ; cerci well developed, four or more 

 times as long as broad in both sexes. 



This genus is referred by Professor Scudder to the group Anosto- 

 stoma, but the little developed spines of the anterior coxse, the fully- 

 developed tegmina and the northern distribution indicate a wide devia- 

 tion from the typical forms. The well developed sound organs of the 

 male tegmina is at variance even with the subfamily characters. It is 

 the only genus of the Anostostoma found farther north in America 

 than Mexico, and as remarked by Professor Scudder, the occurrence of 

 the genus so much farther north than any of the allied genera is very 

 singular. The old world representatives of the group are found in the 

 southern hemisphere.

Description. — Head subglobose, rather deeply inserted in the prothorax ; fastig- 

 ium of the vertex broad, separate from the front and produced very slightly between 

 the antennse ; eyes rounded, broadest above, widely separated, being separated by a 

 space nearly five times as broad as one of the eyes. Antennse slightly longer than 

 the body in both sexes, filiform, slightly tapering, basal segment long and about 

 twice as broad as the succeeding ones, second segment subquadrate, less than half as 

 long as the first ; third twice as long as broad, the succeeding ones, up to about the 

 fiftieth, transverse, the remaining ones longer than broad. Clypeus broader than 

 long, narrower below ; labrum longer than the clypeus and as broad as the lower 

 portion of it ; terminal segment of the palpi slightly longer than the preceding one. 

 Pronotum broad, subtruncate both before and behind in the male, in the female broadly 

 rounded behind ;' in the male the pronotum is ampliate in front to receive the head 

 and behind is still more ampliate and much inflated so as to overlie for some distance 

 the base of the wings, the posterior lobe is flattened above and is much broader than 

 the anterior lobe; in the female the pronotum is subcylindrical, scarcely broader 

 behind than in front and scarcely at all inflated ; in both sexes the pronotum is some- 

 what constricted mesially and the lateral lobes are shallow, posteriorly rounded, not 

 at all sinuate, the lower margin meeting the anterior margin in a broadly rounded 

 angle Tegmina of the male broad and ample, usually covering two thirds or more 

 of the abdomen ; stridulating area well developed and the lateral field broader than
