MÉgnin (Les Parasites et les maladies parasitaires, p. 139; 1880) 

 ideutifies this species with GL cursor Gerv. (= domesticus de Geer). 

 Certaialy he is wrong. 



I have fouud one specimen among numerous Aleurobius farinae 

 sent to me by Mr. S. A. Poppe of Vegesack. I will describe this 

 species afterwards in the Tijdschrift voor Entomologie.

A beautiful well characterized species. Curious is that Kramer 

 ranges under the characteristics of the species : that the front- 

 hairs stand close together ; that the legs are provided with a few long, 

 thin-haired hairs ; that the oval body has numerous very long hairy 

 hairs ; that the hair on the distal end of the tibia is very long and 

 smooth ; that in both sexes there is between the coxae (read trochan- 

 teres) of legs I and II a split on the body, over which a bifid 

 feathered hair is spread. Now these are characteristics to many 

 species of Glycyphagus, e. g. Gl. cadaverum (Schrank), and GL 

 domesticus (de Geer), what Kramer could have known (observed). 



Further he says : the front-hairs stand on a long, narrow anterior 

 dorsal plate. — This also characterizes GL domesticus (de Geer). 



Kramer's only so-called specifi.c character consequently is : that the 

 male is ornated with a comb-like hair on the distal and ventral end 

 of tibia I and IL Now this is not a specific, but only a sexual 

 characteristic. How the species is characterized is hitherto not 

 elucidated.
