1. DocEMA GALAPAGO“NSE, G. R. Waterh. 
Haltica galapagoénsis, G. R. Waterh. Ann. and Mag. N. H. 
1845, xvi. p. 39. 
Hab. Charles Island (C. Darwin). 
2. LoNGITARSUS LUNATUS, sp. n. 
Ovalis, convexus, piceo-testaceus, nitidus ; thorace convexo, paulo 
latiore quam longiore, postice parum angustato, fere levi ; 
elytris basi thorace vix latioribus, medio rotundato-ampliatis, 
erebre evidenter punctatis, lunula communi picea notatis. 
Long. 13 millim. 
Closely resembles L. ballot, Marsh., in form and general appear- 
ance. The antenne are nearly the same; but the second joint is a 
little more pear-shaped ; and the third is as long as the second, but 
more slender. The thorax is a trifle less broad, and not visibly 
punctured. The elytra are very convex, much rounded at the sides, 
broadest across the middle, the shoulders almost completely effaced ; 
the surface is somewhat uneven, which makes the punctuation less 
distinct ; and the punctures are rather closer and finer than in 
L. ballote; a lunate pitchy band is placed across the middle. 
Hab. Charles Island (C. Darwin). 
GALERUCID. 
DraBRoTIcA LIMBATA, Sp. 0. 
Nigra, nitida; thorace pallide flavo; elytris piceis, obsolete 
costatis, inter costas irregulariter biseriatim striato-punctatis, 
apice levi, marginibus flavis ; antennis basi pedibusque obscure 
testaceis, tarsis fuscatis. Long. 2 lin. 
Head shining black. Thorax scarcely broader than long, a little 
narrowed towards the base, pale yellow, with two well-marked 
depressions on the disk. Elytra pitchy; at their base not quite 
twice as broad as the thorax, rather broader behind, obsoletely cos- 
tate towards the sides, with double irregular lines of distinct (but 
rather fine) punctures between the costee ; the apex nearly smooth ; 
the margins pale yellow, the yellow part widening at the apex. Legs 
yellowish, the knees and tarsi slightly dusky.
