580 Mr. C. 0. Waterhousc on Coleoptera 



hrunneo-seneous, shining. Head densely and rugosely punc- 

 tured in front, the punctures slightly seprirated on the vertex. 

 Thorax broadest behind the middle, slightly narrowed in 

 front, scarcely sinuate before the ba^al angles, which are 

 slightly acute, but not prominent ; the sides very gently 

 arcuate. Disk with a distinct but not very deep longitudinal 

 impression extending from the base to the front margin. 

 The punctures on the disk arc distinct, not very close togctler; 

 at the sides they are closer and stronger, and are somewhat 

 crowded near the front angles. There is a deep fovea at the 

 base, near the posterior angle. The elytra strongly punctate- 

 striate, the striae rather deeply impressed near the suture, 

 the interstices convex near the suture, less so laterally, the 

 second and fourth costiform at the apex. There is a shallow, 

 wnnkled impression at the base ; a moderately large, dis- 

 tinct, oblique, reniform imjjression at the middle ; and an- 

 other transversely ovate one halfway between this and the 

 apex The apex of each elytron gently emarginate, the 

 sutural and lateral teeth subequal. Femora blacki>h ieneous, 

 shaded with purple at the apex, Tibise and tarsi ferruginous, 

 ^^ith very short pubescence. Antennae obscure seneous, the 

 third joint very long, the fourth rather shorter, the following 

 gradually decreasing in length. Abdomen in the middle 

 finely punctured, the punctures not very close together ; at 

 the sides the punctures are very fine and much closer, with 

 some fine pubescence. 



Long. 14—22, lat. 4^-7 mm. 



Hub. Ecuador, Sarayacu, and Chiguinda [Buckley). 



The small specimen, which is a male, is more golden gi-een 

 below, with coppery shades, and the femora are green. 



Halecia sexcostata, sp. n. 



Form of the preceding, brownish aeneous above and below, 

 shining. Head closely and rather rugosely punctured in 

 front, the punctures slightly separated on the vertex. Thorax 

 shining, slightly narrowed in front, the sides gently arcuate, 

 very slightly sinuate before the posterior angles, which are 

 somewhat acute. The disk with a not very deep longitudinal 

 impression extending from the base to the front margin. 

 The surface on each side of this with distinct but rather 

 small punctures, whirh are rather widely separated; towards 

 the sides the punctures are somewhat stronger and crowded, 

 the intervals having a tendency to form short oblique rugae. 

 There is a fovea at the base near the posterior angle. The 

 elytra strongly punctate-striate, the second, fourth, and
