1897.] THE SPECIES OF THE GENUS MELAXOPLUS. 25 



notched and rarely, and then but slightly, elevated api- 

 cally; furcula rarely (and then but little) less, usually 

 more, than half as long as the supraanal plate ; hind 

 tibiae green or blue, rarely (^M. complanaiipes) reddish 

 yellow (Cinereus series). 

 ^^ Furcula of male only moderately broad at base, 

 tapering uniformly, not more than half as long as the 

 supraanal plate ; cerci uniformly incurved through- 

 out, not nearly reaching the tip of the supraanal 

 plate ; the latter abruptly and strongly contracted 

 shortly before its tip. 



A\ Prozona of male quadrate or transverse ; apical 

 margin of subgenital plate of male, as seen from 



above, well rounded bispinosus. 



If. Prozona of male a little longer than its basal 

 breadth ; apical margin of subgenital plate of male, 

 as seen from above, rounded-angulate. Jerminalis. 

 g'\ Furcula of male unusually broad at base, usually 

 tapering unequally, the narrowing beginning beyond 

 the base and leaving a portion of the apex equal and 

 very slender, the whole considerably more than half 

 the length of the supraanal plate ; cerci bent sud- 

 denly inward before the tip and at the tipreassuming, 

 at least in part, the original course, reaching the tip 

 of the supraanal plate; the latter with no abrupt 

 preapical constriction. 



k^. The distal twist of the male cerci conspicuous 

 and involving the apical half of the same. 



P. Furcula of male narrowing uniformly or 

 almost uniformly throughout ; hind margin of 

 pronotum very obtusangulate ; disk of pronotum 

 dotted obscurely if at all with fuscous, .cyanipes. 

 i'\ Furcula of male with a considerable part of 

 the apical portion equal and very slender; hind 

 margin of pronotum only a little obtusangulate ; 

 disk of pronotum generally distinctly dotted 



with fuscous cinereus. 



h^. The distal twist of the male cerci inconspicu- 

 ous, involving only the extreme tip. 



/\ Tegmina long and very slender, far surpass-
