REVISIoy OF THE MELAXOl'II—SCrDDER.

lou-ier than thr hind femora and only twice a8 long hh the pron«)tnm 

 nlone ; face rarely as d<cli\ ent as in Paroxya ; pro/ona UNnally a half 

 lonj^er thrn the nietazonn. 

 /'. H<'ad not, lar«;e in proportion to pronotnni, nor proniintMit, hut 

 little lon<;«'r than the pro/ona, niih'ss (as in MilanophiH apretun) 

 the latter is distinctly transverse; pronotnni in no way suhsellate, 

 nor tlarint; in front; tej^mina, when fully developed, narrow, ranly 

 (MelaiiopliixdaH-soni,^ M. cxtremiiH, M. mardinntiis, etc.) rather hroad, 

 but then very distinctly taperinjr, more or less taperin;; in jlistol 

 half, at a distance from tin- apex equal to the hreadth «»f the teg- 

 mina distinctly narrower than the nietazona. the intercalaiiesand 

 «T08s-vein8 of the discoidal area (rxcejit in M. dairaoni completuH and 

 M. nt'trfihiatuH amplii*i) relatively numerouH, at least in the apical 

 fjurth and usually throughout, the venation in general sharp and 

 dearly d«tined, the are; intercalata generally distinctly deline«l 

 by the adjustment of the ^eins at its distal exiremitv, the humeral 

 vein straightand apical.j' arcuate, nearly always terminatingeither 

 on the apical margin or but a short distance before it, running for 

 some distance almost exactly parallel to the costal margin ornu'rg- 

 ing insensibly into it; cerci of male very variable, very rarely 

 (ilelanopliia fiabeUatiis, M. j>Me>) sulistyliform. and then the sub- 

 genital plate is either exceptionally broad, or only moderately nar- 

 row and the apical margin elevated 23. .Ve/an<>/)/«« (p. 120). 



/■-. Head large in jiroportiou to i)ronotuni, especially above, and 

 prominent, ut-arly half as l<»ng again as the long prozona; pro- 

 notum faintly subsellate, feebly tiaring in front to receive the head ; 

 tegmina. when fully developed, broad and subciiual, hardly taper- 

 ing in the distal half, at a distance from the apex eciual to the 

 breadth of the tegmina as broad as the metazona, the intercalariea 

 and cross-veinsof the discoidal area every wh«'re few, the venation 

 in gt-neral loose and ill defin< d,the area intercalata not distinctly 

 marked by the adjustment of veins at its distal extremity, the 

 humeral vein (the upper of the pair of stout veins from th«' upper 

 attachment) broadly sinuous, terniinatinii' on the costal margin 

 at least as far before the apex as the breadth of the tegmina, 

 nowhere running clos«'ly parallel to that margin nor merging into 

 it; cerci of mah- styliforni, the subgenital j)late very narrow, the 



margin not apically elevated 24. Phoetaliotes {ji.376) 



i-. Dorsum of pronotum twice as long as average breadth, at least 

 in the mah-, with no median constriction; antennae, at least in 

 the male, generally longer than the hind femora and nnich nuu'o 

 than twice as long as the pronotum, generally twice as long as 

 head and pronotum together; face more decliveut than in Melan- 

 oplus: j)rozona only about a third longer than the nietazona. 



2.5. Paroxya (p.3;^0). 



h'. Inferior genicular lobe of hind femora wholly pallid, with no dark 



basal spot or transverse band ; cerci of male conical or subcouical or 



basally bullate, always apically pointed. ' " ^ 



*'. Subgenital plate of male terminating in a pronounced tubercle; 



prosternal spine slender 26. Poecilotettij- (p. ;S8;">). 



i-. Subgenital plate of male, even when apically angulate. not fur- 

 nished with an apical tubercle; prosternal spine stout. 

 jK lielatively heavy-bodied; dorsal disk of i)rozona tumid mde- 

 pentb-ntly of the nietazona; pronotum distinctly angulate or con- 



*In form of tegmina and sparseness of nenration this species is the Melanophis 

 moBt nearly allied to Phoetaliotes, and like it it is dimorphic as to tegmina.
