G4 EPILACHNA. 



meridional form of E. borealis; Mulsaut does not differentiate 

 them at all. Varieties occur suffused with black, leaving only the 

 shoulders pale. 



Epilachna borealis. 



Coccinella borealis, Fabr. Syst. Eat. p. 82. 22 (1775). 



Epilachna borealis, Muls. Spec. p. 827. 98. 



Epilachna jnaculiventris, Bland. Pr. E. 8. Phil. in. 72 (18G4). 



North and Central America in profusion. 



Punctuation fine, coarser punctures obsolete ; varieties occur 

 with immaculate thorax (immaculicollis Cheer.) from Mexico, and 

 others in which the rows of spots form transverse hands; a partial 

 arrest of pigment also produces singular effects; but all these are 

 readily referable to their type. 



In this, as well as in the preceding species, the outer edge of 

 the elytra is sometimes black. 



This, the only N. American species, is the only one on the 

 continent at all like the European and Asiatic group in colour- 

 ation. 



Epilachna marginella. 



Coccinella marginella, Fabr. Mant. Ins. p. 53. 3 (1787). 

 Coccinella palliata, Fabr. III. Mag. n. p. 253 (1803). 

 Epilachna palliata, Muls. Sjjec. p. 844. 10. 

 N. Granada, Bolivia. Cayenne, Brazil (Muls.). 

 Plates complete, epipleurae acuminate at five-sixths ; punctu- 

 ation close, large punctures visible. 



Epilachna cacica. 



Coccinella cacica, Giur. Icon. p. 319 (1844). 



Epilachna cacica, Muls. Spec. p. 842. 109.

Epilachna serva, Muls. Op. vn. p. 135 (185G). T. 



Ega, Santarem, Obydos (Bates), Minas Geraes, Bolivia (Mul- 

 sant). Peru, Quito. 



Differs from E. marginella only by the black suture and juxta- 

 marginal band; 1 have several intermediate forms with the suture 

 normal, and consider that it is probably a variety ofE. marginella. 



Epilachna extrema sp. n. 



Very like E. marginella, of which it may be an extreme 

 variety. 



It differs by the black thorax, of which only the anterior 

 angles have a triangular ochreous patch : and by the elytra, of 

 which the external margin i- ochreous, the rest deep brownish- 

 black, with an ovate discoidal rufous vitta in each. 



Ecuador (Buckley). A tolerable number of precisely similar 

 specimens occurred, one of them affording a lead in the direction 

 of E. marginella.
