 Ledromorpha, Melich. (part.) nee Stal, Horn. Faun. Ceylon, p. 1 40 (1903). 



Type, L. aurifa, Linn., a Palaearctic species. 



Distribution. Palsearctic, Oriental and Malayan llegions. 



Head with the vertex laminate, transverse, obtusely angulate 

 anteriorly and obliquely angulate in front of eyes ; pronotum 

 hexagonal, more or less longitudinally ridged, sometimes with 

 laminate processes, anterior margin nearly straight, wider 

 than the posterior margin wliich is deeply sinuate ; scutellum 

 somewhat small ; tegmina coriaceous or seraicoriaceous, the veins 

 prominent ; head beneath foliaceous before the face ; posterior 

 tibiae laminately widened, outwardly remotely dentate and ciliate. 



The foliaceously or laminately widened posterior tibiae and the 

 laterally angulated vertex in front of eyes are distinctive characters 

 of this genus. 



A. Pronotum longitudinally ridged, or carinate ivith elevated 



laminate jyrocesses,

" Greyish or flavescent-greyish ; body beneath and legs pale 

 testaceously-flavesceut or testaceously white ; tegmina greyish, pel- 

 lucid behind middle, a broad pallescent, obsolete fascia near base ; 

 wings sordidly hyaline ; abdomen above flavescent sanguineous ; 

 pronotum elevated posteriorly, furnished on each side with 

 an erect process produced forward and posteriorly marginally 

 creuulate ; sometimes with two interrupted fasciae on the head 

 beneath and some median markings on the pronotum, black. 

 Structure of L. aurita, Linn, but head more roundly produced, 

 pronotal processes longer; head somewhat shorter than pronotum, 

 gradually distinctly amplitied for a short chstance before the eyes, 

 thence abruptly angulated and anteriorly much rounded, the area 

 of the ocelli impressed, the impressed portion forwardly amplified 

 and gradually merged in the anterior disk, anteocular area 

 remotely sprinkled with distinct granules ; lateral margins of 

 pronotum parallel at apex, thence somewhat backwardly divergent, 

 tw^o parallel ridges behind the middle which are anteriorly slightly 

 divergent, obtuse, minutely tuberculate and towards the sides a 

 lobiform crest, very high, slightly bending forward, remotely 

 granulate, posteriorly crenulate ; scutellum gradually transversely 

 depressed towards the middle, before middle laterally sprinkled 

 with granules, posteriorly much elevated, the elevated area 

 posteriorly black and granulate ; tegmina gradually slightly ampli- 

 fied beyond the middle, thence outwardly rounded, nearly the 

 whole of clavus and corium towards base punctured and sprinkled 

 with granules at intervals, veins here and there infuscate ; tibiae 

 above sparingly granulate." {St&l.)
