Scudder.] 484 [April 7, 



with darker and paler markings, similar to those seen in T. viridifas- 

 ciata, with a broad longitudinal green stripe down the middle of the 

 basal half of the wing, in green female specimens; wings sordid 

 hyaline, with a greenish tinge near the base, a diffused black stigma 

 on the costal margin, and very faint and diffused infuscation along 

 the outer border; hind femora of the color of the body, marked 

 above with blackish at the base and tip, and in two spots near the 

 middle ; hind tibiae glaucous, the extreme base blackish, followed by a 

 pale annulation. Summit of head well arched, the vertex somewhat 

 declivant, scarcely sulcate, as broad as long, even in the male rather 

 broad at the extremity; frontal costa broadening distinctly between 

 the antennae, rather deeply sulcate throughout, separated from the 

 fastigium of the vertex, at least in the male, by a slender transverse 

 ridge; antennae longer than the head and pronotum together. Prono- 

 tum rather delicately scabrous, the median carina low, equal, rather 

 distinctly cut in the middle by the transverse furrow, the disc but 

 little tectiform, the lateral carinae rather distinct, subparallel on the 

 front lobe, divergent behind; front margin of pronotum scarcely 

 angulated; hind margin right-angled, the angle rounded. 



Length of body, d, 17.15 mm., ?, 24 mm.; of antennae, <?, 7 mm.,

I have received specimens from California from Mr. Henry Ed- 

 wards, named for me by Mr. Thomas, and others obtained at San 

 Diego, Cal., by Mr. Crotch. 



In the Synopsis of the Acrididae of North America, p. 103, Mr. 

 Thomas says of T. infuscata (which, in the explanation of his plate, 

 he places as a variety of T. viridifasciata) : " This is very closely allied 

 to T. pacifica, and if it were not for the widely separated localities in 

 which they are found, they might be considered as varieties of one 

 species." There is, indeed, between the males such a general resem- 

 blance as one might expect between species of the same genus, but 

 the females of T. pacifica, which Mr. Thomas appears not to have 

 seen, differ extraordinarily from those of T. viridifasciata] even the 

 males are so different that Mr. Thomas's remark seems very strange;
