Coleojytera from Ceylon, 207 



sericeo nitidus " would seem to express, and the thorax can 

 scarcely be called " subtrans verso." The species belongs to 

 the narrow forms of the genus, and the thorax is cordate with 

 prominent angles, as broad as long only at its apex.

Peradeniya, in hot sandy places. 



The broad white vitta on each elytron extends from the 

 middle of the base to four fifths the elytral length, and leaves 

 the sutural (one or two interstices) and a broader but more 

 irregular marginal vitta of the dull blackish ground-colour. 



Subfamily Demetbiikjs.

Motschulsky's description of hisgenus Tetragonica is full and 

 accurate ; I can only add to it that the feebly emarginated tip 

 of the ligula bears two bristles, that the surface of the tarsi is 

 clothed with a number of stiff hairs, and the side of the thorax 

 has two setffi, the first before the middle and the second near 

 the hind angle. It is nearly allied to Demetrias^ with which 

 it agrees in the paraglosste not surrounding the apex of the 

 ligula, which is horny and slightly emarginated, and the acu- 

 minated palpi, characters which, according to Chaudoir, 

 exclude Demetrias and its allies from his subfamily Callei- 

 dinee. The thorax is truncated at the base and shows no 

 tendency to the lobular form characteristic of the Lebiince, 

 Cymindinse, and most of the Dromiinee. 



The genus Peliocypas, of which Schmidt-Gobel describes 

 four species from Burma, agrees exactly with Tetragonica^ 

 except that the labial palpi are truncated. If it could be sup- 

 posed that so careful an observer had mistaken the form of 

 the labial palpi, some of his descriptions accord well with 

 Ceylonese species of Tetragonica.
