XXX. — l)rsrn'/>tion of a new Snecies q/'Mantidae. 

 By I'rof. J. W(mH)-Mason. 



Fischeria laticejjSj n. sp. 



Afale. Body very long and filiform. AntennaB tolerably 

 stout, rather Ioniser than the protiiorax. Head very broad, 

 fully twice as broad as high, compressed, its frontal surface 

 much inclined, flat ; the vertex narrow, slightly arcuate in 

 outline a.s seen from the front. Ocelli oval, placed on the ends 

 of the rays of a triradiatc elevation, the lower one a little 

 larger than the two upper ones. The face apparently as in 

 Fischeria ocelhita^ Saussure. P]yes eonij^ressed and laterally 

 prolonged into a cone, the apex of which is blunt. 



Prothorax slender and much elongated, not longitudinally 

 keeled above, only just perceptibly increasing in width from 

 the supracoxal dilatation to the base, its margins finely and 

 smoothly denticulate in front, the denticles, or rather granules, 

 being quite rudimentary behind the dilatation ; the ventral 

 surface of the neck thinly sprinkled with sharp granules, as in 

 several allied fomis. 



Coloration, texture, and general structure of the tegmina 

 and wings as in Fischeria ocellata ; the discoidal nervure of 

 the latter simj)le ; both in repose reaching as far as to the 

 apex of the fourth abdominal segment. 



Legs very long and slender. The coxas of the fore legs 

 slightly curved, their anterior crest w'ith numerous very 

 minute denticles, the posterior finely serrated ; femora very 

 slender, their upper margin straight, the lower faintly arcuate, 

 with four spines on the outer edge, and with a line of granules 

 along the middle of the unarmed portion ; tibia; straight, 

 armed with fourteen spines on the iimer, and with seven on 

 the outer edge, the base of wliich is unarmed. The four 

 posterior femora have a fine distantly spiimlose crest on the 

 lower and inner margin ; and the four posterior tibitc and tai'si 

 are armed below with two marginal rows of movable spinules. 



Abdomen of uniform width throughout ; the suj)raanal 

 plate longitudinally sharply carinate, triangular, acuminate at 

 the extremity; the infragenital transversely convex, extending 

 rather beyond the basal third of the cerci, its basal third 

 })arallel-sided, its tenuinal and free two thirds acute-trian- 

 gular, and truncate at the very tip, which carries the two minute 

 styles. Cerci very long, compressed, closely similar to tjiose 

 oi' Archii/umtis latist^lus, ditlering from them, in fact, only in 

 being somewhat less strongly comuressed and rather narrower. 



Female unknown.
