442 Prof. J. Wood-Mason on a new Species of Mantidse. 



high, that the vertex is hardly so elevated, and that the eyes 

 are more produced laterally and are armed with a conspicuous 

 bluntish spine ; vertex divided by four slight impressions 

 into three lobes, the two median ones of which impressions 

 pass down on to the front round the elevation that carries the 

 ocelli to the bases of the antennae ; " chaperon " scarcely twice 

 as broad as long, transversely carinate, with its sides slightly 

 convergent below, and with its upper and lower margins almost 

 straight, divided off from the upper part of the face by a well- 

 marked groove ; the facial shield, or the part of the face inter- 

 vening between the "chaperon " on the one hand and the ocelli 

 and the bases of the antennse on the other, is marked with two 

 shallow pits placed symmetrically one on each side of the 

 middle line, is deeply emarginate at its upper angles for the 

 insertion of the capillary antennas, and has its lower angles 

 produced downwards, so that its inferior margin is concave. 



Prothorax shaped just as in HeterochcBta temapes, long and 

 slender, fully as wide at its hinder extremity as it is at the 

 setting-on of the fore legs, with its lateral margins very 

 minutely denticulate, especially in front, with scattered minute 

 granules and a sharp, fine, longitudinal raised line on its disk ; 

 its supracoxal dilatation feeble, rounded at the sides. 



Organs of flight tolerably well developed, extending a little 

 beyond the third abdominal segment. Tegmina narrow, of 

 uniform width, narrowly rounded at the extremity, pale luteous, 

 semiopaque ; basal half of the anterior margin gently arcuate. 

 Wings tricolorous, being coloured red, yellow, and brown with 

 amethystine reflections ; subhyaline, their anterior margin pale 

 luteous ; the discoidal nervure simple, the membranous spaces 

 on either side of it each with a longitudinal row of minute 

 brown blotches on a pure sulphur-yellow ground ; posterior 

 area pale rose-red at the base, then brown, and finally barred 

 with concentric alternate bands of bright sulphur-yellow and 

 brown, the yellow bands being by far the broader, and all 

 becoming gradually narrower and less distinct towards the 

 posterior margin, and all being everywhere broken up into 

 blotches occupying only the membranous interspaces between 

 the nervures. 



First pair of legs tolerably long and slender ; the coxas un- 

 armed, their three strong crests being only a little scabrous, 

 about half the length of the prothorax, uniform in width, 

 straight; femora rather longer, shaped like those of H. tenuipes-j 

 tibiae straight, armed on the inner edge with fourteen spines, 

 with nine on the outer edge, the base of which is unarmed, 

 exclusive in both cases of the relatively enormous and very 

 strongly curved terminal claw.
