No. 34-] HEMIPTERA OF CONNECTICUT: SALDIDAE. 409 



It should be noted that the generic arrangement is according to 

 Reuter, and the species, as well as nomenclature follow Van Duzee, 

 to agree with his Catalogue and facilitate reference. Where 

 species are placed in genera other than those to which they are 

 assigned by the latter author, it is because careful checking up of 

 descriptions and specimens has shown unequivocally that they 

 belong where they are now placed. All of our species belong in 

 the subfamily Saldinae. 



Key to Genera. 



1. Ocelli more distant from the eyes than from each other, or con- 



tiguous. Scutellum longer than wide 2 



Ocelli at equal distances from each other and from the eyes. 

 Scutellum subtransverse [Orthophrys] 



2. Membrane with four entire areoles ; or with five areoles, of which 



the subexternal or 4th is shorter than the others, leaving the 3d 



and 5th contiguous for a greater or less distance apically 3 



Membrane with five complete areoles Pentacora, p. 410 



3. Sides of pronotum more or less explanate ; anterior pronotal callus 



never reaching its lateral margins 4 



Sides of pronotum scarcely explanate ; anterior callus occupying 

 all or nearly all the width of the pronotum li 



4. Apex of pronotum nearly as wide as the head, which is slightly 



wider ; hemelytra thickly, and usually distinctly, punctulate ; or 



subcoriaceous 5 



Apex of pronotum narrower than the head; or if nearly as wide, 

 hemelytra impunctate 6 



5. Membrane usually with five areoles, of which the subexternal (4th) 



is shorter than the neighboring tliird and fifth; last female ven- 

 tral segment truncate [Chiloxanthus] 



Membrane with four complete areoles of nearly equal length; 

 last female ventral segment roundedly produced [Halosalda] 



6. Apex of pronotum nearly as wide as head with the eyes, callus 



moderately convex, sulcus behind the callus without impressed 



points and transverse rugulae 7 



Apex of pronotum distinctly narrower than the head taken with the 

 eyes, callus strongly convex, anterior and posterior limiting sulci 

 deep, furnished with impressed points and longitudinal rugulae. 

 (Hemelytra opaque, only the costal area of the corium and 

 embolium shining) [loscytus] 



7. Antennae slender; third joint of posterior tarsi equal to or but 



slightly shorter than second 8 



Antennae stout; third joint of posterior tarsi distinctly shorter 

 than second [Calacanthia] 



8. First or inner areole of membrane produced but little more than 



one-third of its own length above the base of the second 9 



First or inner areole of membrane produced two-fifths or one-third 

 above the base of the second. (Hemelytra often punctate, 



always without sericeous spots. Embolium entirely black) 



Salda, p. 412 



9. Corium with one distinct vein, the interior vein often obliterated 



toward the apex. Apex of the first, or interior, areole placed 

 distinctly above the apex of the second, very rarely reaching it, 



in which case the corial veins are obsolete 10 



Corium with two perfectly distinct veins, the inner furcate toward 

 the apex, the branches reaching the membranal suture. Apex of 

 the first or interior areole of the membrane reaching or nearly 

 reaching the apex of the second Saldula, p. 412
