PSYCHE. 



285 



Fhiloxanthus n. g. 



Agrees verj closely- with Cockerelli.i in 

 venation and palpial characters, but is readily 

 distinguished by the color of body which is 

 ■wholly yellow, the abdomen being immacu- 

 late; the supraclypeal plate not being dis- 

 tinctly separated; the clypeus being semi- 

 circular at base; while the hind trochanters 

 have a distinct flocculus ; claws simple. Type 

 Peydita beata Ckll. 



Nomadopsis n. g. 



Separated at once from Perdita, Cockerellia 

 etc. by the longer marginal cell which is 

 much longer than the stigma, fully twice as 

 long, or as long as or longer than the first 

 discoidalcell ; submedian cell a little shorter 

 than the median ; maxillary palpi 4-jointed, 

 the first joint very long, fully 7 times longer 

 than joints 2-4 united, with a contraction 

 at base. Type Perdita zotialis Cr. 



NEW TETTIGONINAE, WITH NOTES ON OTHERS. 



BY C. F. BAKER, AUBURN, ALA. 



Xerofhloea major n. sp. Length 7.5 mm., 

 width across pronotum 2.5 mm. Larger, 

 more robust, and more coarsely pitted than 

 viridis. The vertex proportionally much 

 larger than in viridis, and broadly, evenly 

 rounded in front, nor at all even subangulate. 



Described from two females in the National 

 Museum, collected by Mr. E. A. Schwarz in 

 Virginia. In the National Museum there is 

 also a specimen from the Fitch cabinet, bear- 

 ing the label " Xerofhloea major, Arkansas, 

 W. S. Robertson." I have a large series of 

 viridis Fab. from California, Colorado, Ari- 

 zona, New Mexico, Texas, Kansas, Alabama, 

 and Brazil. Major differs as above stated 

 from anything in this series. The forms of 

 this genus, occurring in the Northeast, 

 should be collected in large series at many 

 points. 



Tcttigonia geometrica Sign. This species 

 is found in the United States, but has prob- 

 ably been confused with bijida Say, which it 

 resembles in a most striking manner. Besides 

 some minor details, geometrica is smaller 

 and lacks the whitish lines on elytra. I have 

 it from Illinois, Washington, D. C Alabama 

 and Louisiana. 



Tettigonia circellata n. sp. Length 6-6.5 

 mm. Pale yellowish, the legs and base of 



venter sometimes bright orange. Front 

 usually with two longitudinal black stripes 

 on disc, a very short one on margin next 

 each antenna, and one transverse on clypeal 

 suture ; all these markings may be obsolete. 

 Vertex with a black point at tip and another 

 at center of disc; two very short transverse 

 lines behind, their inner ends embracing the 

 ocelli, and a large incurved line on each side 

 near the anterior margin, arising near the tip ; 

 these markings vary in intensity but are dis- 

 tinct in all the specimens. Pronotum, except 

 anterior margin, pale blue; disc with four 

 black spots, one on either side before the 

 middle and one on either side behind the 

 middle ; other small dots inay occur between 

 these. Scutel yellowish, with two more or 

 less exposed dots at base and transverse line, 

 black. Elytra bright blue by reflected light, 

 the apical margin transparent and the prin- 

 cipal veins blackish ; by transmitted light, 

 the elytra appear deep smoky, with a slight 

 bluish tinge. Wings deep smoky through- 

 out. Prosternum, dorsum largely, and some- 

 times a median longitudinal row of small 

 dots on venter, black or blue-black. 



Last ventral segment of female twice 

 length of preceding, medially raised into a 

 strong keel, the acute point of keel termin-
