and more convex insect than the male. Occasionally the knobs 

 on the superior surface of the connexivum are absent. When alive 

 these insects are grass-green above, with the corium more or less 

 bright wine-brown. Specimens from San Domingo seem to 

 be usually more rugose upon the pronotum and wing-covers and 

 flatter near the anterior angles of the pronotum than in the 

 series which I have examined from the United States and Mexico. 

 Specimens from Grenada are on the average more smooth than those 

 from San Domingo. In my collection there is a graded series which 

 takes in the various modifications from E. comuta, Burm., with narrow 

 and acute scutellum and coarse deep punctures, through the mode- 

 rately smooth and remotely punctate E. albirenis, to the smooth 

 E. sigillata with obsolete punctures on the pronotum and scutellum. 



2. Edessa eegueosa, sp. nov. 



Form of E. rufo-marginata, De Greer, but of the size of E. medi- 

 tabunda, Fabr., which it somewhat resembles. Bright green, 

 moderately polished, wrinkled on the head, pronotum, base of 

 scutellum, and base of costal area, with the hemelytra wine-brown, 

 and the lines of the clavus, reticulations of tip of corium, most of 

 the costal area, and underside of the body yellow. Head short, 

 minutely but distinctly punctate, bordered on the sides and tip 

 with yellow; antennae honey-yellow, the basal joint much thicker 

 than the following ones, the second shorter than the third, the 

 fourth only a little longer than the third ; rostrum rufo-flavous, 

 reaching midway between the fore and middle legs, and fitting 

 into the fork of the mesosternum. Pronotum transverse, coarsely, 

 deeply, irregularly punctate in somewhat transverse series, the 

 sunken space in front of the callosities and behind the eyes densely 

 aud finely punctate ; callosities and their diagonal continuation 

 smooth, impunctate ; lateral margin reflexed, smooth, yellow, the 

 humeral angle prominent, a little rounded, smooth, the post- 

 humeral submargin sunken, with two lines of close punctures ; the 

 posterior margin a little arcuated, the submargin bordered with 

 a line of fine sunken punctures ; pleural border beneath the lateral 

 margin linearly callous, grooved and punctate in continuity with 

 the underside of head. Sternal pieces remotely punctate ; the 

 mesosternal plate corresponds with that of E. meditabunda. Scu- 

 tellum moderately long, very moderately convex at base, depressed 

 next the tip, less coarsely but deeply, not closely punctate, some- 

 what rugose on the base and middle, more finely punctate 

 posteriorly, the sides slenderly bordered with yellow, and the tip 

 acute. Clavus narrow, punctate with red in two approximate lines, 

 the margin cariuately elevated; corium bordered next the clavus with 

 two strong punctate ridges, which are hollowed inwardly by two 

 corresponding lines of rufous sunken punctures ; the punctures of 

 the disk fine and even, those of the base coarser ; costal area con- 

 tracted at base, set near the base with small, yellow, transverse 

 callosities between the reddish punctures ; membrane bronze-brown, 

 with the veins darker. Legs honey-yellow, obsoletely punctate,
