A large number of the species of this genus are poorly described; 

 as a matter of fact it is difficult to distinguish the species in this 

 genus without mounting them in balsam and studying the characters 

 afforded by the fore wings, their relative shape and size and the 

 amount and quality of their discal ciliation ; there are also other 

 good sculptural characters on the metathorax, but coloration is too 

 variable for specific characters in most instances. 



DESCRIPTIONS OF SOME NEW HEMIPTERA- 

 HETEROPTERA. 



By H. G. Barber, 

 RosELLE Park, N. J. 



Jalysus elongatus, new species. 



Longer than /. spinosits Say, pale ochraceous in color. Head twice as 

 long as broad, armed at vertex with a long, acute, cylindrical spine which 

 usually projects horizontally beyond apex of head. This spine in a few cases 

 is deflexed at apex. Post-ocular part of head much longer than in spinosus, 

 as long as the width of the anterior margin of the pronotum ; area back of the 

 transverse groove smooth ; a longitudinal, smooth, callosed line just above the 

 eyes. Head beneath with a series of fine punctures beside the buccal groove 

 and with a smooth pale-yellow, callosed line running from beneath the eyes to 

 the anterior edge of the pronotum, suffused with a light piceous streak either 

 side of this line. First joint of rostrum three fourths as long as head. 

 Antennae similar in character and color to spinosus but with the apical joint 

 relatively narrower. Pronotum over twice as long as wide, closely and coarsely 

 punctate dorsally and laterally except on the two oval cicatrices and on the 

 three longitudinal callosed ridges which are arranged as follows : lateral ones, 

 distinct from anterior margin to rounded humeral elevations, median carina 

 not elevated behind, evanescent before posterior declivity. Spine of scutellum 

 depressed, almost horizontal. Clavus and subclaval area of hemelytra punctate, 

 these verging posteriorly into shallow areoles ; remainder of hemelytra and 

 membrane transversely rugulose between the prominent nervures and there 

 subhyaline. Very acute and prolonged apex of corium reaching well beyond 

 middle of membrane, not tipped with black. Abdomen beneath impunctate, 

 unicolorous in J and reddish brown in J'. Pleural pieces of meso- and meta- 

 sternum coarsely and closely punctate. Metapleural spines relatively shorter
