/;/;/ isio ^ or TIIK MELAXOTLISCUDDER. 67 



pallid at base, slightly darker and sometimes infuscated at tip, nearly 

 as long as (female) or much longer than (male) head and pronotum 

 together. Prouotum tectilbrin with a feeble blunt and equal median 

 cariua, which is often but not always, sometimes conspicuously, pink 

 roseate; prozoua much longer than, in the male half as long again as, 

 the metazona, rugulose, the raised portions generally more or less 

 yellowish and having often a transverse, never a longitudinal trend; 

 the metazona equally rugulose, but with a distinct longitudinal trend 

 to the raised portions; hind margin obscurely and obtusely angulate. 

 Tegmina green or yellowish green, the longitudinal veins being yellow 

 and the ground green ; they taper to a roundly acuminate tip and are of 

 variable length in both sexes, but always considerably longer than the 

 pronotum, in the male usually about two-thirds the length of the abdo- 

 men, in the female generally varying from two-thirds as long as to quite 

 or nearly as long as the abdomen; wings pellucid green, with green 

 veins. Hind femora green, the outer half of the upper surface below 

 the carina often roseate, and the inner surface generally pale yellow; a 

 faint sign of a pregenicular roseate auuulation often appears ; hind tibiae 

 green, the spines pallid or yellowish green with black tips. Supraanal 

 plate of male triangular, with slightly sinuate sides, the apex some- 

 times acute, sometimes rounded, with a rather broad and deep median 

 sulcus in the basal half, bounded by a rather high and acute ridge on 

 either side, between which and the margin is a rather deep and very 

 broad valley; a slight median sulcus appears in the apical half; furcula 

 consisting of a pair of approximate, little protruding, triangular lobes; 

 cerci delicate and slender, tapering gently and more on basal than on 

 apical half, though sometimes the apical half is nearly equal, bluntly 

 acuminate at tip and with the outer half distinctly incurved; apical 

 tubercle prominent, conical, more or less appressed; sometimes slightly 

 transverse as viewed from behind, and occasionally (as in the figure; 

 by accident in drying?) bifid.
