208 J. Wood-Mason— On the Genus Pbyllothelys. [No. 3, 



The forelegs are long and slender. The coxae are triquetrous and 

 when laid back do not reach to the base of the pro thorax ; their inner 

 face is coloured red- violet surmounted on the upper crest by yellowish 

 marked with 10 — 13 minute elongate black spots lying at the bases of as 

 many minute black spinules, between which are some very much more 

 minute yellowish ones. The femora are very slightly sinuous above, but 

 arched below ; their outer face bears one distinct oblique bar and a minute 

 mottling of a darker shade of brown than the ground-colour ; their inner 

 face is black, with the apex, a complete transverse bar nearer to the ungual 

 groove than to the apex, and an oblong mark nearly midway between 

 the ungual groove and the base on the upj^er half, all yellow ; tibiae 

 jet-black internally and below, armed on the inner edge with 14 — 15 and 

 on the outer edge with 16 teeth, the basal five only of which are more 

 recumbent than the rest and even they do not nearly touch the margin, 

 or even one another ; the intermediate and posterior legs are short ; 

 they are ridged as in Phyllocrania ; the posterior of their lower crests 

 bears a foliaceous lobe divided by an emargination into a very small 

 proximal and a much larger distal portion with a rounded and nearly 

 entire margin ; the tibiae have no foliaceous crests, but, in lieu thereof, 

 the proximal half swollen and thickened club-like laterodorsally, as 

 in one or both of the same pairs of legs in the species of the tropical 

 American genus AcantJwps and its allies. 



Organs of flight extending very little beyond the extremity of the 

 abdomen, coloured. Tegmina coriaceous, opaque umber-brown anteriorly, 

 posteriorly membranous and hyaline covered irregularly with brown- 

 smoky spots, which tend in places to coalesce so as to form a coarse 

 mottling ; anal gusset reticulate, with the membranous meshes smoky 

 and the net- work obsoletely lined with hyaline ; the stigma elongate, 

 polished. Wings with the anterior margin semiopaque umber-brown, 

 the apex of the anterior area distinctly brown-spotted like the corres- 

 ponding part of the tegmina ; all the rest of the organs brown smoky- 

 quartz-coloured, gradually increasing in intensity from the base to the 

 outer margin, and tolerably distinctly lined with hyaline on both sides 

 of the transverse veinlets. 



Abdomen broad and depressed, gradually widening from its base 

 to the end of the 4th somite, whence it widens with greater rapidity to 

 the end of the 5th, the posterior angles of which are produced outwards ; 

 the rest of the abdomen forming a triangular mass the sides of which 

 are slightly jagged owing to the production of the posterior angles of the 

 dorsal arcs of the 6th and 7tli somites ; the terminal dorsal arc is crescent- 

 shaped, longitudinally roof-shaped, and more than twice as broad as long.
