5^8 j\Ir. C. O. Waterliouse on Cohoptera 



Autennse greenish blue. Thorax one quarter broader than 

 long, obliquely narrowed in front, almost rectilinear at the 

 middle (not anj^nlatcd), slightly sinuate before the posterior 

 angles, whieh are only very slightly or scarcely divergent. The 

 disk is longitudinally, moderately strongly impressed, with a 

 sharjjly defined central impressed line extending from the 

 front margin to the basal round fovea. The punctuation on 

 the disk is n odcrately fine and not very close; at the hind 

 angles it is stronger but not closer ; the area of the anterior 

 ang'es is closely and rather strongly punctured. The elytra 

 at the humeral callus are only slighily wider than the thorax, 

 but gradually widen for three fifths their length, and then 

 narrow to the ajjcx ; the apices very acute. Each elytron 

 has a very slightly raised obtuse costa near the sutuie ; a 

 second extending from the shoulder joins the first near the 

 apex; a thiid very oLseure one commencing below the 

 shoulder ; and the usual sublateral one. The third costa has 

 a very slight interruption about the middle, and behind the 

 middle it is interrupted by a moderately large but very 

 shallow impression. 



Long. .21-20, lat. 7-9 mm. 



Hub. Ecuador, Balzar [Buckley). 



This species is near H. rugipennis, L. & G., but rather 

 differently coloured. The thorax is straighter at the sides, 

 and the diseoidal impression is of more uniform width, and 

 the median line is very distinct and extends the whole length. 



Halecia avropimctata, Kerr. 



There is a specimen in the Museum from Bogota which 

 has scarcely any trace of the spots on the elytra so con- 

 spicuous in the type sj)ecimeus of this species. 



Halecia trilineata, sp. n. 



Closely allied to H. octopunctata, Fabr., and H. decemim- 

 pressa, Saund. Above obscure purple ; below bright golden 

 green. Head very closely and finely punctured ; with a 

 narrow green line bordering the eyes, widening somewhat on 

 the lower part of the face ; there is a short, slightly impressed 

 median green line above the clypeus. Thorax convex, 

 narrowed towards the front, the sides rectilinear ; the 

 surface is rather closely punctured, the punctures rather 

 stronger and rather more asperate than in H. \0-inipressa. 

 There are three green lines as in that species, but they are 

 scarcely impressed. There are two small impressions near
