No. 34-] HEMIPTERA OF CONNECTICUT I CERCOPIDAE. 233 



and veins strongly elevated and accentuated with pale vi^hitish 

 yellow, the enclosed areas light fuscous (subvar. a), or clavus 

 entirely fuscous (subvar. b), inner claval margin at base, costal 

 margin near base and beyond middle, short oblique stripe on disc, 

 sinuous band enveloping corium anteriorly and reaching to the 

 prominent black callous spot on margin before apex, dark fuscous ; 

 dorsal surface varyingly punctate, clothed with a short, sparse, 

 yellow pubescence ; undersurface and legs yellow, marked with 

 dark piceous ; legs with spurs and spines stout. 

 C. delicata var. (ii) binotata Ball. 



Black ; a distinct circular yellow depression on vertex between 

 ocellus and eye on either side, a small spot at middle on costal 

 margins, and the tibiae variably spotted with creamy white. 



Distribution: Specimens have been examined from Colorado. 

 It has been reported from California and Arizona (Ball), and 

 from Utah (Uhler). 



Considerable difficulty is experienced in dealing with this species 

 due to the extreme variability in both size and coloration. As 

 Dr. E. D. Ball (1895) stated, "Uhler's description is an absolutely 

 perfect one for var. i. lineata subvar. a, but would apply only 

 slightly to subvar. b, and would absolutely exclude var. ii binotata/' 

 I have no hesitancy in agreeing with Mr. E. P. Van Duzee (1912) 

 in his conclusion that "C lineatocollis Stal is certainly a distinct 

 species and not a variety of C. ohtusa (Say) as stated by Dr. Ball." 

 After a careful study of available material it seems highly probable 

 that the description lineatocollis refers to those forms included by 

 Uhler and Dr. Ball under the name of delicata Uhler, in which 

 case the latter name must be supplanted under the law of priority. 

 However, due to the noticeable vagueness of Stal's description in 

 certain instances and the insufficiency of material at hand, it seems 

 inadvisable to make such a change in nomenclature at present ; and 

 I am including lineatocollis therefore as a questionable synonym 

 of delicata, and have appended hereto the original description of 

 lineatocollis for facility of comparison.
