ORPHULELLA. 



its widest part ; ulnar area of the $ occupied by a single row of 

 cells, rarely partially divided into two sets by an irregular spurious 

 vein. 

 b 1 . Lateral carinse of the pronotum nearly straight, parallel, slightly 

 divergent posteriorly, or very faintly arcuate on the prozona. 

 c 1 . Antennae of the $ not longer than the head and pronotum 

 together, basally depressed and apically subacuminate . . . 

 c 1 . Antennae of the $ a little longer than the head and pronotum 

 together, of equal size throughout and nowhere flattened . . 

 b\ Lateral earinae of the pronotum distinctly bent, often greatly 

 divergent both in front and behind. Anterior ulnar vein of 

 the c? tegmina distally much nearer the radial than the lower 

 ulnar vein. 

 c x . Narrowest (middle) portion of the pronotal disc more than three- 

 fourths the width of the broadest (posterior) portion .... 

 c 2 . Narrowest (middle) portion of the pronotal disc not more, 

 generally less, than three-fourths the width of the broadest 

 (posterior) portion. 

 d 1 . More or less variegated, the tegmina usually with a median 

 series of spots. Antennae of the $ not longer than the head 

 and pronotum together; hind margin of the pronotum ob- 

 tusely angulate. 

 e l . Fastigium of the vertex less sharply angulate and less 

 prominent, in the <$ advanced beyond the eyes by not 

 more than one-third the length of the eyes as seen from 

 above, in the ? generally roundly obtusangulate . . . 

 e\ Fastigium of the vertex more sharply angulate and more 

 prominent, in the <$ advanced beyond the eyes by half or 

 nearly half the length of the eyes as seen from above, in 

 the ? generally distinctly rectangulate. 

 f 1 . Normally brown or testaceous, seldom with much green . 

 f 2 . Normally grass-green, never brown, seldom testaceous . 

 d 2 . Rarely variegated, the tegmina usually immaculate ; antennae 

 of the £ longer than the head and pronotum together ; hind 

 margin of the pronotum rounded, scarcely angulate . . . 

 A*. Discoidal area of the basal half of the tegmina of the ? scarcely 

 narrowed distally, and here nearly always occupied by more than 

 one row of cells, and little, if any, narrower than the ulnar area at 

 its widest part ; ulnar area of the $ either divided into two series 

 of cells by a more or less distinct spurious vein, or irregularly 

 reticulate, never occupied throughout by a single series of cells. 

 b\ Lateral carinas of the pronotum distinctly arcuate, the disc of 

 unequal width, being narrower (often considerably narrower) in 

 the middle than behind, and generally than in front.
