NORTH AMERICAN COLEOPTERA. 113 



NOVIUS Muls. 



Two species of this ^•enus have been introduced into California 

 for their utility in the destruction of Icerija pni-cJum, which threat- 

 ened to destroy, or very greatly injure the orange and lemon ti-ees 

 of that State. 

 3f. cardiiialis Muls. 



This insect was originally described as Vedalla, but recent re- 

 searches place it in Nomas. Chapuis places these two genera in 

 separate groups, and as these two groups, Ortaliites and Scymnites, 

 are separated especially by the thorax narrower at base than the 

 elytra in the former it would seem preferable to remove Novias from 

 the Scymnites and place it nearer to Rodolia and Vedalia. 



N. vardinalis Muls. — A species as large as Exochomus mnrffvuipennis, but 

 more depressed. Its elytral markings are strikingly similar to some of the va- 

 rieties of that species. The elytra are red, the suture narrowly bliick, with two 

 slight enlargements, the apex is black, extending oue-third or more to humerus 

 and at its end expanded, a spot partly surrounding the umbone and an oval spot 

 one-third from apex. The legs are black, often with the tibite and tarsi carmine- 

 red. PI. II, fig. 9. 



This insect is now thoroughly acclimated in the citrus growing- 

 regions of California, and very full accounts of it have appeared in 

 many publications in that State and in " Insect Life," Washington. 



Inti'oduced from New Zealand. 

 1S\ Koebelii Ollitfe. 



This is somewhat smaller than cardinalk. The elytra are reddish, 

 the suture narrowly black, the same color extending around the apex 

 and sides to middle. Specimens are frequent with the elytra entirely 

 red. Thorax entirely black, while that of cardmalbi is pale at the 

 sides. 



This species does not seem to have gained the footing of c<i,rditt.(i/is 

 although fairly acclimated. 



Specimens were given me by Mr. A. Koebele, who was instru- 

 mental in introducing them from Australia, their native region. 



€0€CIDIIL,A Kug. 



This genus is usually placed in a group without other associates, 

 distinguished from all the pubescent Coccinellidte by the faint at- 

 tempt at a strial arrangement of some larger punctures. It must, 

 however, be admitted that this character seems to fail almost entirely 

 and can be seen better l)y faith than with the lens. 



Two species occur in our fauna. 



a lepidn Lee, Proc. Acad. 1852, p. 282. The figure (PI. II, tig. 

 12) gives a fair idea of the form and markings of this species, other- 

 wise well described by Dr. LeConte.
