92 NAEMIA. 



Megilla. 



Mais. Spec, p 24 (typ. maculata). 



Claws dentate at the base ; the thorax not longer than broad ; 

 punctuation faint, superficial. Elytra with a humeral plic;i in 

 the 5 • America. 



Megilla maculata. 



Coccinella maculata, Be Geer. Mem. v. 392. 1, pi. 16. 22 

 (1775). 



Megilla maculata, Muls. Spec. p. 28. 4. 



Coccinella limensis, Philippi Stett. E. Z. xxv. p. 402 (1864). 



Ncemia fuscilabris, Muls. Mon. p. 22. 2 (1866). 



America, from Canada to Chili. This is one of the most vari- 

 able of the Coccinellidce. In the north it is generally small (2| — 3 

 lin.) clearly and distinctly spotted, opaque and very obsoletely 

 punctured; in the South and especially in the rich Amazonian 

 regions it apparently becomes much larger (4 lin.), is shining and 

 faintly punctured, loses the humeral spot and by coalescence ac- 

 quires two fasciae behind the middle. 



Megilla quadrifasciata. 



Coccinella i-fasciata, Sch'On. Syn. Ins. u. 178. 69 (1808). 



Megilla 4t-/asciata, Muls. Spec. p. 25. 2. 



Var. Megilla 18-pustulata, Muls. Spec. p. 26. 3. 



Brazil, Buenos Ayres, Chili. These two species differ just as 

 do the varieties of M. maculata mentioned above ; M. 18-pustulaCa 

 is the opaque smaller form, differing from M. i-fasciata by having 

 the black fascia? connected with each other by a longitudinal line, 

 thus dividing each elytron into nine orange spots. M. i-fasciata 

 is larger, and shining. 



Megilla innotata. 



Megilla innotata, Muls. Spec. p. 24. 1. 



W. Indies. Porto Rico (B. M.). At once distinct by the black 

 prosternum. 



Naemia. 



Muls. Spec. p. 30 (typ. seriata). 



Distinguished by the simple claws, and the shorter thorax, the 

 base of which is markedly sinuate. 



Naemia seriata. 



Coccinella seriata, Melsh. Proc. Phil. in. p. 177 (1847). 

 Naemia Utigiosa, Muls. Spec. p. 31. 1.
