ART. 7 REVISION OF COCCOPHAGUS COMPERE 9 



Coccophagus is composed primarily of reticulated lines and setiger- 

 ous punctures. The varied punctulate and sliagreened effects seen 

 in tag mounts are due to the differences in the fineness of the pat- 

 tern and size of the raised lines or reticulations and to the size and 

 abundance of the setigerous punctures. 



Color. — The varied color patterns furnish the "most conspicuous 

 and easily seen taxonomic characters. Unfortunately, coloration is 

 not always reliable, for certain species are extremely variable. 

 Other species have a very uniform color pattern. C. ishiii, new 

 species, has been described as new on the basis of the different color- 

 ation of the fore coxae. This species is not readily separated from 

 C. scutellaiis (Dalman) by any structural characters known to me. 

 It differs from C. scutettaris (Dalman) principally by having the 

 fore coxae black, in contrast to the remainder of the fore legs, which 

 are yellow, and in contrast to the fore coxae of G. scuteUaris which 

 are yellow and concolorous with the remainder of the fore legs. 

 In this case, the distinction seems justified, for C. scuteUaris is rep- 

 resented in our collection by a large series of specimens and the col- 

 oration of the legs is constant. On the other hand, a color differ- 

 ence such as this is not of sufficient value to justify separating cer- 

 tain other forms. A series of O. malthusi Girault exhibits an amaz- 

 ing range of color variation and if it were not for the intergrading 

 specimens the extreme variants could not be recognized as being 

 specifically alike. On the basis of coloration three species described 

 by Girault, namely, C. leptos-pervii., C. triguttatus., and G. triangu- 

 latinotus seem quite distinct, yet in structure and size they seem sus- 

 piciously alike. If they prove to be as variable in coloration as is 

 G. malthusi Girault, it is not unlikely that they will prove to be 

 specifically identical; however, this can not be determined from an 

 examination of the badly mounted types. Many of the species are 

 most conveniently separated on the basis of coloration, for this can 

 be seen at a glance. However, coloration can not be used as the 

 basis for an exact and scientific classification.
