(Note. — The synonymy of this and other species of 

 Scudderia was very badly confused until Scudder in 1898 

 finally fixed the standing of the then-known species; and 

 students should be very cautious in accepting specific names 

 of the genus used by writers before that date.) 



Descrip'ion. — Like other reoreseatatives of the ^eaus, this species 

 has a very odd appearance with its long antennse, leaf-like wing-covers and 

 wings, and long and very slender hind-legs. — Disk of pronotum distinctly 

 broadening from the front backward; wing-covers leaf -like, fairly broad 

 (the length about 3 times the greatest breadth). Supra-anal spine of male 

 forked, the apical notch acute and shallow, without a median tooth, and 

 narrower than the uoturned sub-anal spine; the lateral processes (on the 

 sides of notch) sub-triangular and distinctly tapering toward their ends when 

 viewed from above, the underside of these processes bearing a small vertical 

 longitudinal flange or keel. Greatest width of ovipositor about J>^ of its 

 upper chord. Hind femora about 21 (male) or 20 mm. (female). Disk of 

 pronotum wider posteriorily than anteriorly, the posterior width 1.5 times 

 the anterior. Females may be distinguished from those of furcata by the 

 shape of the pronotum disk, and from curvicauda borealis by the relatively 

 broader wing-covers. 



Colour. — From five males, just taken, Halifax, N. S., 26 Aug., 1895. 

 General colour above, including wing-covers, pale oil-green or apple-green; 

 under parts whitish green. Antennas brownish, greenisli basally; upper part 

 of eyes brown; vertex of head white, middle of face greenish-white, mouth 

 and between legs white. Dorso-lateral angle of pronotum with a creara- 

 bufT stripe. Abdomen terre-verte green, malachite-green on sides; posterior 

 margin of abdominal segments brighter green (appearing as annular stripes 

 of brighter green on darker green); two longitudinal, slightly raised, white 

 lines on ventral surface of abdomen. Soles of feet brownish.

*Walker listed two species of Katydid as havini; b:^pn taken in Nova Scotia by Ijieut. 

 Redman, to which he applied the names "Phaneroptera curvicauda Do Geer" and "Ph'iUoptera 

 mj.rtifolia Serv." Until the specimens in the British Mu.'^eum are carefully examined by some- 

 one perfectly familiar with the North American forms as at present rcconnized, the best we 

 can possibly say is that these two names as used by Walker to desiKnatc Nova Scotian speci- 

 mens, represent two of the three forms •'Scudderia pistillata, S. curvicaiula burealis, and S. furcata 

 /areata.
