1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 99 



niargia with a short perpendicular groove. Elytra distinctly 

 punctate-striate ; their epipleurse very broad, concave, and continued 

 to the apices ; posterior femora strongly thickened ; tibia? not 

 channelled, the posterior ones with a short spine ; the first joint of 

 the posterior tarsi as long as the two following joints together ; 

 claws appendiculate. Prosternum broad, one half longer than broad. 

 Mesosternum transversely quadrate. Anterior coxal cavities open. 



The rounded convex shape, the short perpendicular basal grooves 

 of the thorax, in connection with the punctate-striate elytra, the 

 broad prosternum, and open coxal cavities separate this genus. 



Thryl^a variabilis, sp. nov. 



Reddish fulvous ; head, thorax, and the legs black ; thorax 

 distinctly punctured ; elytra strongly punctate-striate, dark fulvous. 



Var. Fulvous ; elytra black, the suture and the apices fulvous. 



Length 1 line. 



Head impunctate, the clypeus thickened ; labrum margined with 

 fulvous. Antennee about half the length of the body, black, the 

 apices of the first five joints stained with fulvous ; the second joint 

 as thick, but half the size of the first, the third and the two follow- 

 ing joints nearly equal, shorter and thinner, the rest more flattened 

 and dilated. Thorax transverse, rather more than twice as broad as 

 long, the sides straight, the anterior angles oblique forming a 

 thickened angle before the middle ; surface finely but distinctly and 

 not very closely punctured, black. Scutellum fulvous. Elytra 

 rounded, strongly and regularly punctate-striate, the interstices with 

 a few fine punctures, slightly convex near the sides and apices, the 

 shoulders thickened and somewhat prominent. Legs black ; tarsi 

 piceous. 



Bogawantalawa. 



Morylus (gen. nov. Halticinorum). 



Body ovate. Antennae slightly widened at the terminal joints, 

 the third and fourth joints equal. Thorax transverse, without de- 

 pressions, the anterior angles oblique. Scutellum broader than long. 

 Elytra irregularly punctured, their epipleuree extending below the 

 middle. The posterior femora strongly incrassate, their tibiee 

 deeply longitudinally channelled, armed at the apices with a small 

 spine ; the anterior tibiae unarmed. Claws appendiculate. Pro- 

 sternum very broad. Mesosternum more than twice as broad as 

 long. Anterior coxal cavities open. 



Mory/ws agrees with Sebaethe, Baly, in the deeply sulcate posterior 

 tibiae, but differs in the shape of the thorax, the sides of which are 

 straight, not flattened or margined, and in the broad prosternum. 



MORYLUS FULVIPENNIS, Sp. UOV. 



Black, head and thorax impunctate ; elytra fulvous, depressed 

 below the base, very closely and distinctly punctured ; legs black. 

 Length \\ line. 



Head entirely impunctate, the frontal elevations in shape of nariow
