In a group where the species are so excessively numerous 

 and closely allied as in the Stenini, great care should be 

 exercised in making synonymical statements, and, it may 

 be added, there are probably extremely few species com- 

 mon to Europe and North America. It is even possible 

 that our familiar juno is not the same species as the Euro- 

 pean juno, for the figure of the male sexual characters of 

 this species given by Rey does not correspond, particularly 

 the modification of the fifth segment, which scarcely agrees 

 at all with the description which I have given for the Ameri- 

 can species. 



VI. 



Pinophili. — The statement made concerning this group 

 (Class. Col. N. A., p. 99), viz, that the species are found 

 under the bark of trees, is erroneous as far as the genus 

 Pinophilus is concerned; the correct derivation of the word 

 is given by Erichson (Gen. Staph., p. 670). Of the four 

 species in my cabinet, the two collected by myself were 

 taken in damp earth, under decomposing vegetable matter, 

 and in a few instances under stones; the other two were at- 

 tracted at night to the electric lights at El Paso, Texas. 



VII. 



Platystethus spiculus Er. — Specimens of this species, 

 which was described by Erichson from Colombia, South 

 America, were recently taken at Galveston and Austin, 

 Texas. These specimens correspond with others communi- 

 cated by Dr. Duges, taken at Guanajuato, Mexico, showing 

 that the species is of very wide distribution. The name 

 should be added to our lists. 



VIII. 



Aglenus Er. — A colony of about forty specimens of a 

 species which is probably A. brunneus Gyll., was recently 

 taken by me in the environs of San Francisco. Full de-
