Bledius dissimilis Fall, 1910, is preoccupied by B. dissimilis Er., 

 1839 (Gen. Spec. Staph., p. 769), and has been changed to " phila- 

 delphicus" by Mr. Fall in Ent. News. B. fratellus Fall, 1910, is also 

 preoccupied by B. fratellus Eppelsch., 1885 (D. E. Z., XXIX, p. 144), 

 and has been changed to " transit us" by Mr. Fall in Ent. News. 



Mycetoporns tenuis Horn, 1877, is also preoccupied and may be 

 replaced by Jiorni n.m. 



In Aleocharin?e certain changes have been made on the basis of a 

 letter from Colonel Casey which will be filed in the minutes of the 

 N. Y. Ent. Soc. 



The name Megalops Erichson, 1840, is preoccupied by Me galops 

 Lacep., 1803, for a genus of fish. The name Megalopsidia may be 

 substituted. 



In Coccinellidffi I assume responsibility for such synonymy as has 

 not already been published ; such being as I believe in harmony with 

 the known variability of the maculation, and with studies on the geni- 

 talia to be published by Mr. P. H. Timberlake. 



Spilota Burm., 1844, is preoccupied by Spiluta Billberg, 1820 

 (Enumeratio Insectorum in Mus. Billberg, p. 61). The latter, ac- 

 cording to a manuscript by Mr. P. H. Timberlake, is a synonym of 

 Coccinclla. It seems as if Pachystctluis Blanchard, 1851, should be 

 used in place of Spilota Burm. 



In Hippodamia the work of Mr. P. H. Timberlake indicates that 

 the study of the genitalia will show that, while the division of the 

 genus into sections based on the form of the claws is confirmed, a 

 larger number of forms are entitled to specific rank than I had sup- 

 posed; and that in the convergens group some of the varieties named 

 by Casey and Johnson have been erroneously placed by them. How- 

 ever, the variability of the genitalia in Lachnosterna has been shown 

 by Glasgow to be rather greater than Smith supposed in his first 

 enthusiastic treatment of that genus; and, as ]\Ir. Timberlake's manu- 

 script (which I have been allowed to read before publication) indi- 

 cates that he desires to confirm his conclusions by the study of more 

 material, I am unwilling to accept a few of the changes immediately. 



The tribe Tetratomini has been transferred from Melandryidse to 

 Mycetophagidse. This reverses Casey's idea (Journ. N. Y. Ent. Soc, 

 VIII, 1900, p. 166), but with his verbal approval, when I visited him 

 in Washington.
