NEW PHYTOPHAGOUS COLEOPTERA 69 
depressed ; elytra scarcely visibly punctured, metallic blue, the 
anterior portion to nearly the middle, fulvous; abdomen black. 
Length 4/, lines. 
Hab. New Guinea, Fly River (L. M. D'Albertis). A single 
specimen. 
Closely allied to N. dimidiatipennis, Baly, but smaller and 
distinguished by the fulvous colour of the head, thorax and 
legs of which only the posterior femora and the apices of the 
tibiae are stained with fuscous; the upper surface is nearly 
entirely impunctate and the fulvous portion of the elytra is 
divided from the metallic blue by a straight line; the antennae 
extend to two third the length of the elytra and their third 
joint is distinctly shorter than the fourth. 
41. Momoea flavomarginata, n. sp. 
Obscure flavous or testaceous; head piceous at the base; elytra 
metallic green, closely punctured, the lateral margin narrowly 
flavous. 
Length 3-4 lines. 
Head with a few remote but distinct punctures, piceous; the 
frontal tubercles, clypeus and the palpi, flavous; antennae longer 
than half the body, the basal joints testaceous, the others more 
or less fuscous or piceous, third joint distinctly longer than the 
fourth ; thorax about twice as broad as long, shining, flavous, 
the sides angulate before the middle somewhat concave below 
the latter, the angles tuberculiform, surface with a deep longi- 
tudinal and a transverse lateral depression, the disc with some 
distinct but remotely placed punctures; scutellum flavous; elytra 
narrowly elongate, closely and distinctly punctured, the shoulders 
prominent and bounded within by a deep longitudinal depression, 
which is continued (much more obsoletely) towards the middle; 
tibiae unarmed; the first joint of the posterior tarsi, longer than 
the two following together; claws bifid; anterior coxal cavities 
open ; elytral epipleurae indistinct below the shoulder. 
Hab. New Guinea, Hatam, June (O. Beccari).
