1 06. Phlugis similis sp. no v. 



Green. Related to virens Thunberg, from which it differs in its 

 somewhat smaller size and the very different subgenital plate of the 

 abdomen of the male. Anterior tibiae four-spined as in P. mantispa 

 Bolivar. 



Pale green, the tcgmina somewhat pellucid. Pronotum unicolorous, 

 the hind margin produced, rounded. Tegmina narrow, their tips 

 about reaching the apex of the subgenital plate of the abdomen in the 

 male, the costal area provided with about fifteen cross-veins. Anterior 

 tibiae four-spined on both margins, those in front rather blunt; the 

 front femora three-spined in front and four-spined behind; middle 

 tibiae two-spined below. Male cerci moderately robust at their base, 

 gently curved, not quite one-half the length of the subgenital plate. 

 The latter large, broad, with the lateral margins nearly parallel on 

 their basal three-fifths, roundly narrowing beyond, the apex deeply 

 cleft and the two branches twisted, so that their upper surface is 

 apposing somewhat after the fashion of the insect determined by me 

 as P. mantispa Bolivar, their upper margin nowise angulate as stated 

 in the descriptions of virens Thunberg and abnormis Redtenbacher. 



Length of body, cT', 9.5 mm., including subgenital plate 12.5 mm., 

 of pronotum, 2.65 mm., of tegmina, 10 mm., of hind femora, 9 mm. 



Habitat. — Bahia, Brazil, October 24, 1907. Collected "by sweeping 

 grass in a garden in edge of the City, J. D. Haseman." The type is 

 the only specimen at hand. It is in the Carnegie Museum, Pitts- 

 burgh, Pa. 



107. Phlugis caudata (Redtenbacher)? 



Thysdrus caudatus Redtenbacher, Mon. Conocephal., p. 223 (1891). 

 Phlugis caudatus Kirbv, Syn. Cat. Orth. B. M., II, p. 285 (1906); Karny, Revis. 

 Conocephal., p. 102 (1907). 



A single male specimen coming from Quatro Ojos, Department of 

 Santa Cruz, Bolivia, where it was taken by J. Steinbach during 

 November, 1913, is referred to this species with considerable doubt. 

 The very abnormal form of the cerci and subgenital plate do not 

 quite agree with the original description. Especially does this remark 

 hold true regarding the sub-genital plates, which are more like long, 

 somewhat flattened, and gently upwardly curved styles, which are 

 widely separated from their base. The costal area of the tegmina is 

 likewise abnormal, being much narrower than usual and with the medi- 

 an vein running lengthwise through its middle jiarallel to the costa.
