214 Mr. H. W. Bates on the Longicorn Coleoptera 



throughout the Amazons region. I did not find it on timber, 

 but on the leaves of trees in the forest. 



2. Carterica cincticornis, n. sp. 



C. minor, modice elongata, depressa, setosa, nigra ; capite (occipite 

 exoepto), vitta lata laterali thoracis, macula parva huraerali femo- 

 rumque basi fulvo-testaceis ; antennarum articulo quarto late tes- 

 taceo annulato, primo infra ciliato ; elytris pone medium paulo 

 ampliatis, apices versus leviter attenuatis, supra grosse punctatis, 

 bicostatis. Long. 2-3 lin. <f . 



Head short, forehead convex, tawny testaceous ; antenniferous 

 tubercles and two broad stripes behind them, united on the oc- 

 ciput, black. Antenna? twice the length of the body, black, the 

 fourth joint, with the exception of the apex, pale testaceous; 

 clothed with short setse, the basal joint furnished beneath with 

 a fringe of long hairs. Thorax scarcely convex, lateral promi- 

 nences placed at a short distance from the base ; black, with a 

 silky fulvous vitta on each side. Elytra depressed, shoulders 

 obtuse, lateral carina proceeding thence prominent, but not 

 visible from above, slightly dilated from the middle to near the 

 apex, then more suddenly attenuated, apex sinuate-truncate with 

 the sutural angle rounded and external angle produced into a 

 stout tooth ; surface clothed with erect brown setae, coarsely 

 punctured, except near the apex, and traversed by two faintly 

 elevated costse, both of which disappear before reaching the apex. 

 Presternum reduced to a very narrow thread ; mesosternum also 

 extremely narrow. Abdomen blackish, clothed with grey pile. 

 Legs moderately slender, basal joint of the posterior tarsi a little 

 longer than the remaining joints taken together; black; coxse and 

 basal halves of the thighs tawny testaceous. 



Ega, rare. I met with two examples only of this pretty little 

 species : its habits are probably very similar to those of C. cincti- 

 pennis, it being found only on the leaves of trees in the shades 

 of the forest. The depressed body, somewhat dilated elytra, and 

 fringed basal joint of the antenna? are so many points of approx- 

 imation to the genus Sparna of Thomson (Systema Cerambyci- 

 darum, Liege, 1864, p. 30), the species of which resemble the 

 dilated forms of the family Lycidse. 



Genus Colobothea, Serville. 

 Serville, Ann. Soc. Ent. Fr. 1835, p. 69. 



The typical forms of this genus are well known to all who 

 occupy themselves with the study of exotic Coleoptera. They 

 are known by their elongate, narrow, and compressed form of 

 body — the vertical, deflexed sides of the elytra being separated 

 from the dorsal surface by an elevated line, which proceeds from
