Tetragonica mellea. 



Melleo-flava ; capite thoraceqiie rufo-velfusco-testaceis, nitidis ; elytris 

 vitta utrinque submarginali vago delimitata (interdum obsoleta) 

 ante apicem intus curvata, fusca ; fronte quadrifoveolato, capite 

 post oculos oblique recte angiistato ; thorace quadrato, latoribus 

 rectis postice perparum sinuatis ; elytris auguste elongato- 

 oblongis, postice paullo dilatatis, apice valde oblique sinuato-trun- 

 catis, angulo exteriore rotundato, suturalique reeto, hand profunde 

 striatis, striis 8-9 approximates, parallelis, interstitiis planis, tertio 

 pimctis setiferis magnis duobus, primo versus basin secundo prope 

 apicem : pedibus curtis, tibiis 4 posticis, intus spinulosis, tarsis 

 supra setis paucis, unguibus pectinatis. 



Long. 6 millim. 



Colombo. 



The four posterior tibiae though slender are slightly thick- 

 ened, or calf-shaped, in the middle of their inner sides. The 

 basal joint of the hind tarsi is nearly as long as two to four 

 taken together. The two setiferous punctures of the elytra 

 occupy the whole width of the third interstice. 



Tetragonica catenata. 



T. mellece quoad formam simillima; colore obscurior ; castaneo-fusca, 

 nitida ; elytris castaneo-ruiis, post medium fuscis apiceque utrinque 

 macula sat grandi flavo-testacea ; antennis, partibus oris pedibusque 

 melleo-flavis ; fronte 4-foveolata ; tboraoe quadrato, angulis posticis 

 valde obtusis vel oblique truncatis ; elytris interstitiis convexis, 

 tertio punctis setiferis sex, quinto tribus, spatiis inter puncta elon- 

 gato-tuberculatis. 



Long. 5 millim. 



Bogawantalawa. 



The elongated tubercles or parts of the interstices between 

 the setiferous punctures, Avhich latter extend across the inter- 

 stices, are chiefly near the base of the elytra. 



Tetragonica intermedia. 



T. mellece quoad formam et colores simillima, diflFerfc solum vitta 

 fusca, postice baud intus curvata apiceque elytrorum late clare 

 flavescenti ; thorace quadrato, angulis posticis fere rectis, nuUo 

 modo truncatis ; elytris subpunctato-striatis, interstitiis paullo 

 elevatis, tertio et quinto punctis setiferis tribus. 



Long. 4^ millim. 



Horton Plains. 



Exactly intermediate in colours, in the form of the hind 

 angles of the thorax and elytral interstices, between T. mellea 

 and T. catenata.
