Dec, 1903 ] Leng : North American Coccinellid.^'. 203 



Sublateral pale spot of thorax united to the pale apex ; body smaller. 



Elytra luteo-tlavate munda. 



Elytra generally bright scarlet polita, 



. Var. immaculata Fab., 1792, Ent. Syst., I, i, p. 267. 



Pronotum black, with a narrow pale side margin extending with equal width 

 posteriorly and internally along the base, terminating abruptly at about lateral sixth 

 and sometimes extending more narrowly along the median parts of the apex, also with 

 an isolated small pale spot at the middle of the length and lateral fourth ; body broadly 

 oval but distinctly longer than wide, the marginal bead of the elytra not or only slightly 

 darker ; metacoxal plates devoid of any trace of an oblique line ; elytra generally luteo- 

 flavate, without distinct paler spaces at the sides of the scutellum ; pronotum of the 

 female generally with the apical margin narrowly pale, usually subinterrupted at the 

 middle and not posteriorly spurred. Length, 5.7-6.0 mm. = .23-. 24 inch. 



Occurs in Florida, Georgia and Louisiana. 



This is a well-marked race and probably exists in all collections 

 possessing southern specimens. 



. Var. rubripennis Casey, 1899, I. c.,p. 92. 



Elytra deep and bright scarlet, with a short transverse paler spot at each side of 

 the scutellum which is black as usual ; pronotum relatively narrower than in vnmactt- 

 lata and rather more strongly roimded at base, the median length relatively greater 

 when compared with the sides, having a narrow apical margin with narrow parallel 

 posterior prolongation pale in the male, the female interruptedly margined with paler 

 and without a medial spur. Otherwise as in preceding. Length, 4.4-5.8 mm. = 

 .18-. 23 inch. 



Occurs at Brownsville, Texas, in Colorado, and in southern Cali- 

 fornia. This is also a well-marked race. The original description of 

 rubripennis is copied from Major Casey's paper, as well as his descrip- 

 tion of immaculata, so that the reader may follow his exact words. 



. Var. munda Say, Journ. Bost. Soc. Nat. Hist., I, p. 202. 



Pronotum as in preceding, except that the apical margin is broadly pale, with a 

 posterior medial spur short and triangular, and the sublateral pale spot is united to the 

 pale apex, but does not join the basal pale area ; body more elongate-oval, the elytra 

 luteo-flavate, with more narrowly reflexed margins, which are always paler. Length, 

 4-5 mm. = .16-. 20 inch. 



Occurs in the Atlantic and Middle States. 



This is the common form of sanguinea with us i the East. 



. Var. polita Casey, 1899, 1. c, p. 93. 



Pronotum as in preceding except that the sublateral spur is longer, frequently 

 joining the basal pale border so as to leave a black spot isolated ; medial spur long 

 and narrow, gradually acuminate and extending to or beyond the middle of the 

 disk ; body smaller and rather more rounded, the elytra generally bright scarlet and 

 with almost completely obsolete punctures, occasionally yellow and in a northern 

 example, with more distinct punctuation. Length, 3.8-4.7 mm. =- .15-. 19 inch.
