COCCINELLA.

3062. Coccinella tricuspis Kirby. 

 Distribution: Canada and neighboring States. 



The elytral pattern of this species is so unique that its relationship is 

 puzzling (fig. 47) . The few specimens known show no si nificant varia- 

 tion. 



3058. Coccinella novemnotata Herbst. 



Distribution: North America. 



Var. spots H-{-L, conjuncta Fitch. 4 

 per cent at Cold Spring Harbor 

 (see fig. 52). 



Var. spots H+I. 

 Var. spots I-\-A. 



Var. spots H-/. Seen on one side only 

 of 1 specimen from Oyster Bay, 

 Long Island. 



Var. spots L+H+L 



Var. spots L -\-H-\-I-\- A, confluenta 

 Fitch. 



Var. dirisicollis Fitch. Black pattern 

 of pronotum touching the cephalic 

 margin caudad to the eyes, but 

 not mesad. Known only from 

 Fitch's description. The prono- 

 tum is in general relatively con- 

 stant (fig. 50). 



Var. degener Casey. The pigment re- 

 duced, the apical spot being re- 

 solved into two (fig. 51). Prob- 

 ably the specimens of C. mene- 

 triesi Mulsant, attributed to Cali- 

 fornia, are of this variety. But 

 as Crotch believes that C. mene- 

 triesi is a variety of C. undecim- 

 punctata, the relation of that 

 species to C. novemnotata requires 

 further study. 



Form A. Some spots lacking. 



Var. franciscana Mulsant. Elytra 

 without spots. 



FlG 49._Variation of elytral pattern in C. perplexa. 



Subspecies of the Plateau States: Variety degener prevails. 



Subspecies oj the Pacific Coast: Varieties degener and franciscana prevail.
