basal ventral segments bearing some punctures. Posterior tarsi 
decidedly sulcate on outer side. 
Length 21, breadth 3 mm. 
New Guinea, Simbang. Gazelle Peninsula, Herbertshöhe. 
(The type is from Simbang.) 
Compared with a species from Astrolabe Bay, which I identify 
as L. politus Chaud., L. nitescens differs (apart from colour) by 
prothorax more depressed, sides less rounded at widest part and 
. much less sinuate posteriorly, basal angles less obtuse; elytra 
more depressed, less declivous to apex, striae much more lishtly 
impressed (especially towards apex), 6% and 7'% interstices quite 
flat towards apex. 
Lesticus Bennigsenin. sp. 
2. Oval, robust, convex; prothorax strongly rounded on 
sides; elytra wide, oval, lightly striate, 3” interstice 3-punctate. 
Head black with occiput metallic green ; prothorax metallic-bronzy- 
green, border piceous; elytra metallic-green, 9% interstice and 
margin obscure, inflexed margin chalybeus; undersurface nitid; 
abdomen black; sternal side pieces metallic (olivaceus); legs black 
. tarsi reddish. 
Head large, convex (4.4 mm across eyes); frontal impressions 
deep, wide, giving off a branch externally just before anterior 
supra-orbital seta. Prothorax broadly cordiform (4.7 > 6.4 mm), 
laevigate; base and apex of equal width (4.5 mm); sides strongly 
rounded, obliquely narrowed to base (hardly subsinuate posteriorly); 
basal angles obtuse; lateral basal impressions shallow ; lateral 
border thick, convex. Elytra convex, oval (12><8.5 mm), 
broadest behind middle, rounded on sides; humeral angle rounded, 
inner angle not marked; striae finely punctate, 7'% deeper than 
others, especially towards apex, 8% and 9% strongly impressed 
and punctate; interstices flat, 7'® and 8'® convex near apex. Pro- 
episterna smooth with four punctures opposite anterior margin 
of coxal cavities; mes-episterna punctate; metasternum on each 
side and met-episterna punctate; 1° ventral segment punctate. 
Posterior tarsi not sulcate externally. 
Length 20, breadth 8.5 mm. 
Gazelle Peninsula, Herbertshöhe. (unique.) !) 
This fine species seems very distinct; compared with 
L. nitescens S]., it differs (apart from colour) by form more convex
