Black, shining ; pronotum, scutellum, and post-scutellum yellowish- 

 white ; four anterior legs for the greater part in front with the tarsi, a 

 band on the outer apical half of posterior tibia3, a large spot over the 

 hind coxa3, a spot on the last abdominal segment, and a number of 

 oblong spots on the sides white ; hind femora reddish, hind tibiaB 

 (except the white band) and tarsi black. Wings hyaline, costa and 

 stigma pale fuscous. 



In the <J the scutellum, abdomen, and posterior femora are black, and 

 there is only a thin pale band on pronotum. 



Length 3 4 lines. 



The lateral abdominal marks are often obliterated, 

 and the scutellum has occasionally a black dot in 

 centre. The scutellum and pronotum are in rare 

 cases quite black. 



The nearest ally of this species is M. 4<-maculata 9 

 Fab. (not a British insect), which is easily separated 

 from it by its white mouth, black pronotum, pale pos- 

 terior coxge and trochanters, and reddish hind tibiae. 



M. punctum album does not appear to be very com- 

 mon. It has been taken in Scotland by Dr. Sharp. In 

 England it occurs in the London districts ; Mr. Smith 

 says (in lit.), " scarce, but once plentiful on a hedge of 

 privet;" near Dover, Grlanvilles' Wootton, Devonshire. 



According to the observations of Katzburg, Saxesen, 

 and Kaltenbach, the totally green larva feeds on the 

 leaves of Ligustrum vulgare and Fraxinus, and Mr. 

 Bridgman finds it on the former plant at Norwich. 



Its Continental distribution extends to Scandinavia, 

 Prussia, Pomerania, South Germany, Hungary, Hol- 

 land, Switzerland, France, Italy, and Spain.
