Psyllobora Chev. 



Body small, convex, pale in color, spotted with a darker tint above ; mesosternum 

 truncate, claws with a large quadrate tooth internally at apex. 



Our species are closely related and may be separated as follows : 



Elytra without sutural common spots, suture pale ; 



Each elytron with nine spots of uniform color some of which may be confluent. 



20=maculata. 



Each elytron with two basal spots and a large reniform discal spot renifer. 



Each elytron with two or three basal spots and seven others variously confluent, 



sometimes differing in color t£edata. 



Elytra with two common sutural spots, the sutural margin narrowly black nana. 



3078. P. 20=niaculata Say, 1824, Journ. Ac. Nat. Sc. Phil., IV, p. 96. 



Small, rounded, convex ; pronotum finely but distinctly punctate, elytra strongly 

 and very closely punctured ; ochreous white, pronotum with five black spots, the 

 ante-scutellar spot small ; elytra with nine spots, two subbasal, two subsutural, three 

 submarginal, two discal, the latter often connected and sometimes joining the others 

 partly together ; sternum and middle of ventral segments black, epimera and part of 

 meta-episternum white. Length, 2.1-2.7 ™in. =.08-. 11 inch. 



Occurs in Atlantic region. 



The following varieties have been described : 



. Var. Obsoleta Casey, 1899,1. c, p. loi. 



The elytral spots are brown instead of black. Length, 2. 15 mm. = .086 inch. 



Type Locality : Keokuk, Iowa. 



With this I include all the specimens from the Middle West in 

 which the color is pale and the spots begin to suggest the Texan and 

 Californian forms. It seems to me at best a feebly differentiated race. 



. Var. parvinotata Casty, 1899, 1. c, p. loi. 



Ante-scutellar spot of pronotum obsolete ; elytral spots smaller and completely 

 isolated. Length, 1.9 mm. = .08 inch. 



Occurs in Florida. 



This variety appears incorrectly in many collections under the name 

 nana, which is described below. 



. P. renifer Casey, 1899, 1. c, p. 102. 



" Body very small, rounded, with very minute sparse punctures; pronotum sub- 

 impunctate, the five spots present but pale brown in color ; elytra very pale yellowish- 

 white, with brown markings consisting, on each, of two subbasal spots, the outer the 

 larger and with a lobe on the callus, a small faint subsutural cloud at one third, a 

 large bilobed discal spot extending from basal third to apical fifth, prolonged and 

 acuminate antero-externally and a large bilobed and less well-developed fine sub- 

 apical spot." Length, 1.6 mm. =: .065 inch. 



Type locality, Brownsville, Texas.
