South- American Colcoptera. 299 



third, densely hirsute. Thorax with rather long fine hairs, 

 strongly and rather thickly punctured, distinctly broader at 

 the base than in front, with a swelling at the side rather be- 

 hind the middle. Elytra purple steel-blue, at the base dis- 

 tinctly wider than the thorax, suddenly expanded immediately 

 below the shoulders, much rounded at the sides, rather thickly 

 and finely punctured near the base, towards the apex and the 

 lateral expanded portion finely frosted ; with an undulating- 

 deep-yellow median fascia ; each elytron has four well-marked 

 costai (the fourth being on the expanded portion, entire) , the 

 second and third are united before the apex, but are continued 

 to the apex by a single one ; there is a yellow spot on the 

 margin just above (and united with) the fascia ; and there are 

 two or three small yellow spots on the costse on a level with 

 the lateral spot. 



This species has the elytra much more suddenly expanded 

 below the shoulders, and more rounded at the sides than any 

 species of the genus known to me. 



Hah. Chiguinda. 



Lycidola retifera, n. sp. 



Nigra, subtilissime pubescens ; thorace lineis quatuor fulvis ; elytris 

 postice bene arapliatis, depressis, fulvis, triente apicali guttisque 

 mimerosis nigris. 



Long. 7 lin., lat. elytr. 4 lin. 



Third and fourth joints of the antennas equal, and scarcely 

 longer than the first, thickened and finely pilose, the following 

 joints together as long as the first four taken together, sparingly 

 pilose. Clypeus and base of the mandibles fulvous. Thorax 

 a little broader than long, slightly narrowed in front, straight 

 at the sides, rather thickly punctured, with a fulvous line on 

 each side, and sometimes with two fulvous lines above. Elytra 

 at the base a little broader than the thorax, evenly but very 

 slightly convex, enlarged immediately below the shoulders, 

 attaining their greatest width at the middle, evenly rounded 

 at the sides _ (rather less so in the male) ; the basal two thirds 

 fulvous with black spots ; each elytron has four lines, repre- 

 senting the usual costae, but which are only raised at the 

 apex ; the intervals have numerous transverse lines, so that 

 the elytron presents five lines of round or ovate black spots, 

 the ground-colour being black ; all the surface is rather 

 closely and strongly punctured. 



Hah. Chiguinda. 



In general appearance this species much resembles Themi- 

 stonoe reticulata, below described. A species of Calopteron in 

 the same collection reproduces the same coloration.
