1908] MORSE — TETTIGIDEAN XOTES 25 



TETTIGIDEAN NOTES, AND A NEW SPECIES. 



BY A. P. MORSE, WELLESLEY, MASS. 



Among some Tettiginae recently received for study from Mr. Wm. T. Davis I 

 find a male and female of Tettigidea acuta Morse taken on Staten Id. in i\pril. These 

 are the first examples I have seen since the preparation of the original description 

 which was based on specimens in the Scudder collection taken by or secured from 

 Uhler and labeled simply "N. Y." This material contains also two females of 

 Tettigidea lateralis from the same locality, one macropterous. Mar. 2, one microp- 

 terous, Oct. 23. 



The most interesting part of the collection, however, is a series of 15 specimens 

 of an undescribed form or species of this genus, related to armata Morse, collected 

 at Perth Amboy, N. J., May 31; Jamesburg, N. J., Aug. 31; and Staten Id., N. Y., 

 in April, June, and August. All are brachypterous, the pronotum nearly reaching 

 or slightly passing the hind knees. This form is distinguished from armata, which 

 it most resembles, by the customary lack of a cuspidate point on the front margin 

 of the pronotum, which is for the most part simply obtuse-angulate with the sides 

 straight, slightly sinuate, or shallowly excavate, occasionally showing variations toward 

 a cuspidate condition. The tegmina are relatively short, bluntly rounded or truncate 

 at apex, with the usual white spot exceptionally large, triangular, sometimes covering 

 nearly two-thirds of the exposed distal half of the tegmina. In size, sculpture of 

 surface of pronotum, and form of vertex it is apparently not distinguishable from 

 armata. 



I take pleasure in naming this species Tettigidea davisi for its discoverer, in def- 

 erence to his studies on the orthoptera of the vicinity of New York. 



A Note on the Distribution of Bittacomorpha jonesi. — Since describing 

 this species (Psyche, XII, p. 75, 1905) from Mt. Taxoway, N. C, I have collected 

 four specimens, June 18, 1906, along the foot of the Hoosac Mt. at Briggsville, two 

 miles northeast of North Adams, Mass., and one specimen near St. Johnsbury, Vt., 

 June 27, 1906, along a branch of the Passumpsic River. Recently Mr. H. S. Harbeck 

 informs me that he has collected a specimen at Clementon, N. J.
