Family Coreidae. 



Subfamily Altbina, Stal. 



T . Genus Paraplesius*. 



Linear. 



Head horizontal : face, central lobe narrow, depressed before 

 reaching the apex, where it curves down, leaving the side lobes 

 projecting witli rounded obtuse extremities. Antennae, fii'st, 

 second, and third joints subequal, fourth longest ; first joint 

 slightly thickened at the apex. Eyes, viewed from above, 

 almost semicircular. Rostrum reaching to the base of the 

 third pair of coxas ; first joint shorter than the head. 



Thorax. — Pronotum slightly shorter than the head, widest 

 across the posterior margin. Scutellum elongate, somewhat 

 naiTOw. Elytra : clavus with a distinct flexible suture. 

 Membrane multinervose, each nerve separate at the base and 

 curved inwardly, except next the apex of the corium, where a 

 small group diverge from a common centre. Legs somewhat 

 long, without spines or teeth : thighs, all the pairs thickest at 

 the apex : tarsi, first joint about one third longer than the 

 second and third together. 



Closely allied to Micrelytra, Lap., but easily separated from 

 that genus by the shape of the head and the difference in the 

 lengths of the joints of the antenna?. 



Paraijlesius unicolor. 



Fulvous or grey-yellowish, thickly and delicately punctured. 



Head above very finely and thickly punctured, here and 

 there with a slight fuscous shade : face, from the base of the 

 central lobe to in a line with the anterior margin of the eyes, 

 a narrow black channel ; base of the former with a minute 

 black spot on each side, Antcnnce grey-yellowish ; first joint 

 more or less distinctly black-punctured ; second and third
