PTYCHANATIS. 123 



variable. Mulsant has placed them in Coccinella and in Anatis ; 

 the antennae are veiyrnuch those of Anatis, the plates are V-shaped 

 as in Coccinella, the elytra have not unfreqnently an apical plica ; 

 the epipleurSe are inclined, but acuminate before the apex.

E. Siberia, N. China, Mandchuria, Japan ; sometimes abun- 

 dant. The fine series brought by Mr Lewis from Japan and China 

 shews conclusively that all the above forms are colour- varieties of 

 a single species. It will be seen that the range of variation is 

 exactly that of Coccinella lO-ptcnctata, and the resemblance is 

 enhanced by the presence (in the majority of cases) of an apical 

 plica. In the present species the extreme black form is not po 

 constant as in C. 10 punctata, where only a humeral lunule is 

 left orange, while here there are one or more spots, or an ir- 

 regular ring red.
