432 Mr. J. Scott on new Genera and Species 



Readily distinguished from the other species by its elongate 

 appearance, the different form of the pronotum, and the rudi- 

 mentary membrane. 



Diplonotus luridus. 



Pale brownish yellow ; elytra finely brown-punctured. 



Head black. Face^ apex of the central lobe more or less 

 brown. Antenyue yellow ; first joint somewhat brown at the 

 base ; third, apex reddish ; fourth, apical two thirds black. 

 Eyes piccous. Rostrum yellowish, apex piceous. 



Thorax. — Pronotum black ; collar brownish yellow, with a 

 transverse row of punctures ; between the constriction and 

 the posterior margin brownish yellow, somewhat thickly 

 brown-punctured, two longitudinal keels and the posterior 

 angles paler. Scutellum black, with a central keel, extending 

 from the middle to the apex, punctured exteriorly, the central 

 keel and two side pieces forming a Y-shaped patch more or 

 less distinctly brown. Elytra pale brownish yellow. Clavus 

 with three rows of brown punctures. Corium : anterior 

 margin pale yellowish white, with two short black streaks — 

 one at the apex, the other almost in a line with the apex of 

 the clavus ; at the inner posterior angle an unpunctured tri- 

 angular patch. Membrane fuscous, nerves white ; on the an- 

 terior margin, a little way below the apex of the corium, is a 

 small black spot, and exteriorly, at the base of the second 

 nerve from the inner margin, is another ; the spaces between 

 the nerves next the apex more or less white, in which are a 

 few minute fuscous spots. Sternum black or pitchy black, 

 finely punctured. Legs yellow : thighs^ first pair reddish 

 brown, apex yellowish, second and third somewhat brownish 

 yellow : tarsi yellow, apex of the third joint brown. 



Abdomen underneath more or less clear chestnut-brown. 



Length 2\ lines. 



At first sight of this insect one is reminded of Ploctomerus 

 luridus ; but its narrower and more elongate form, longer 

 head, thicker anterior thighs, and different number of teeth on 

 the latter easily separate them. 



There are only two specimens of this species in the collec- 

 tion. 



Diplonotus lateralis. 



Black, not shining ; anterior margin of the elytra yellowish 

 white. 



Head black, finely shagreened. Antennce hxown ] first joint 

 darker than the second ; third black, base dark brown ; fourth 

 black, basal third yellowish, base with a narrow black
