CHILOCORUS. 185 



California, Texas, Mexico, \V. Indies, S. America. 

 Punctuation very fine and sparse, hardly coarser on the 

 margins of the elytra. 



Chilocorus renipustulatus.

Coccinella renipustulata, Scriba, Jotirn. p. 276. 161 (1792). 



Chilocorus renipustulatus, Muls. Secur. p. 168. 1 (1846). 



Europe; on various trees (Fraxinus, Salix, Alnus). Japan 

 (Lewis). The Japan specimens (15) are exactly like C. bivulnerus 

 in the round punctiform dot exhibiting no trace of any transverse 

 tendency. 



Chilocorus bivulnerus. 



Chilocorus bivulnerus, Muls. Spec. p. 460. 10. 



United States; very near C. renipustulatus, and sometimes 

 hardly to be separated from it ; Mulsant relies on the punctiform 

 spot and the red epimera. 



Chilocorus pleuralis.* 



Chilocorus pleuralis, Lee. Proc. Phil. p. 90 (1859). 



Hemisplnericus, niger, subtiliter punctulatus, elytris macula 

 rubra, magna rotundata ante medium signatis, epipleuris ante 

 medium late rufomarginatis, parapleuris rufis. L. 26. California. 



Larger than C. bivulnerus and C. f rater mis, differing by the 

 red spot being placed before the middle, and the abdomen entirely 

 black. 



Chilocorus fraternus.* 



Chilocorus fraternus, Lee. Pacif. Expl. Surv. IX. Ins. p. 70. 

 (1857). 



Chilocorus canariensis, sp. n. 



Chilocorus renipustulatus f, Wall. Cat. Can. Col. p. 424 (1864). 



The Canarian specimens from Teneriffe and Gomera that I 

 have examined, seem to differ from the ordinary European 

 C. renipustulatus, by their smaller size and very transverse dis- 

 coidal spot; they approach C. bipustulatus in this, but I have 

 not seen any specimens in "which the spot looked as if it might be 

 divided ; and the black head would moreover distinguish it from 

 that species. The first 3 ventral segments are clouded with black 

 in the middle. 



Chilocorus bipustulatus. 



Coccinella bipustulata, Linn. Syst. Nat. p. 367. 28 (1758). 

 Chilocorus bipustulatus, Muls. /Secur. 170. 2. 

 Europe, N. Africa, Syria, Persia. Recognizable by its red 

 head.
