Longicornia Malayana. 619 



A very distinct genus^ the type of which, as M. 

 Lacordaire observes, has a very striking resemblance to 

 Tricondyla among the Oicindelidce. A second species 

 has been described by M. Chevrolat, from the Philip- 

 pines. 



Selefhrus amcenits.

Hah. — Singapore (and India and Philippine Islands). 



Black ; head with a pale blue spot behind each eye ; 

 prothorax with a black pubescence in front, the posterior 

 two-thirds glabrous, purple, slightly nitid, closely punc- 

 tured, four pale blue spots above, and one on each side; 

 scutellum small, triangular, pale blue ; elytra with the 

 basal half, or a little more, purplish, subnitid, finely punc- 

 tured, a pale blue spot on each toward the base, the 

 posterior half pubescent, black, with two transverse pale 

 blue lines ; body beneath black, with a few blueish sjDots ; 

 femora reddish-testaceous ; antennae brownish-testaceous^ 

 washed with pale blue, the scape black. 



Length 7-9 lines. 



The two following genera have been omitted by M. 

 Lacordaire. One of them, Acrocyrta, is expressly ex- 

 cluded from the Glytince (p. 58, note) on account of the 

 length of its antennse, but as it has the intermediate coty- 

 loid cavities angulate, it cannot be placed with either the 

 Heteropsinoe or Bhopalopho7-ince, to both of which it is allied. 

 The other genus, Demonax, has latterly been referred by 

 its author to Acrocyrta, but I think it is quite distinct. 

 For the present, I am content to place them at the end 

 of the Glythyx.
