Hab. Surinam, Venezuela. 



I have given here another and more detailed description 

 of this species (Proc. Zool. Soc. 1889) of which seven spe- 

 cimens are before me. Galerucella 4 lineata Latr. seems to 

 be a somewhat nearly allied species, but is of reddish brown 

 colour with long an tenn a3 and the latter of diiferent colora- 

 tion. The following species from the Argentine Eep. seems 

 likewise to be undescribed. 



Galerucella interrupta sp. n. 



Obscure testaceous, with very short pubescence, antennas 

 black (the base of the lower joints excepted) thoracic punc- 

 tuation variable, the disc trifoveolate and with three obscure 

 spöts, elytra with three, more or less interrupted black stripes. 



Length 5 (q*) — 7 ($) millim. 



Mas. Head finely rugose, nearly black, not longer than 

 broad, the eyes widely separated, antennse extending scarcely 

 further than the base of the elytra, black, the base of the 

 lower three joints more or less testaceous, third joint elongate 

 and the longest, the terminal joints widened, the last four 

 scarcely longer than broad; thorax twice as broad as long, 

 the sides nearly straight, the posterior margin slightly con- 

 cave in front of the scutellum, the surface with an obsolete 

 but broad lateral and median depression, closely but rather 

 obsoletely punctured and sparingly clothed with some very 

 short pubescence, testaceous, the depressions blackish, scutel- 

 lum very broad, testaceous, elytra extremely closely and 

 rather finely punctate-rugose, with traces of longitudinal
