Astathes and allied Genera of Longicom Golcoptera. 63 



Hah. SlAM (Type $ , in coll. Oberthlir) ; and S. India, 

 Madras, Nilgiris. 



I have been unable to detect any sufficient specific 

 difference in the examples from South India. They agree 

 in all essential respects with' the type. In the latter, the 

 head is not darker at the base of the antennas, and the 

 dark spot behind each eye is very faint ; but the same is 

 true also of most of the South-Indian specimens. 



2. Cleonaria cingalensis, sp. n. 



Apical fourth or fifth part of the elytra dark metallic-blue ; the 

 coloration of all the remaining parts of the insect very similar to that 

 of C. bicolor, Thorns. Head with a median, carini-form tubercle on 

 the lower part of the front in the male, slightly gibbous in front in 

 the female. In other structural characters, and in general form, the 

 species agrees with G. bicolor.

Genus Chkeonoma. 



Chreonoma, Pasc, Trans. Ent. Soc. Lond., (3) iii, p. 358. 



Head broadly and moderately concave between the antenniferous 

 tubercles. Antennae a little longer than the body in the male 

 usually shorter than the body in the female ; first joint asperate in 

 front at, or near, the apex ; second joint nearly twice as long as 

 broad. Prothorax transverse, sub-cylindrical, protuberant, or not, 

 at the middle of each side ; the disc with a more or less distinct 

 median elevation. Elytra slightly widened out posteriorly, rounded 

 and unarmed at the apex, without raised lines. Prosternum not 

 very strongly raised between the coxae ; mesosternum sloped in front, 

 prolonged between the middle coxae for the greater part of their 

 length. 



Type of the genus : Chreonoma venusta, Pasc. 

 The more typical species of this genus form a group or 

 section distinguished by the following characters : 



Scape of the antennae as long as, or slightly longer than, the third 

 joint, gradually and slightly thickened towards the apex ; last joint 

 sharply pointed and sub -glabrous at the tip. Prothorax very 

 slightly or not at all protuberant at the sides ; the anterior groove 

 feeble and indistinct, especially in the middle ; the posterior groove 

 distinct at the sides, very narrow and strongly bowed back in the
