DOLERUS LATERITIUS. 163 



Easily recognised from the other British species by 

 the three black marks on the mesonotum. 



The only British example of this insect that I have 

 seen was one taken by the Rev. T. A. Marshall in 

 England, but I do not know the exact locality ; those 

 in Stephens' s collection were taken in the neighbour- 

 hood of London. 



Continental distribution : Sweden, Germany, Hol- 

 land, France, Switzerland, Russia.

Black ; head and thorax covered with a dense greyish pile, breast 

 and mesonotum in the middle finely punctured and shining ; pleura? 

 with large but not very deep roundish punctures ; prothorax, tegulas, 

 the apical half of the mesopleurse and mesonotum (save the scutellum 

 which is black) reddish ; abdomen dilated, smooth and shining, red- 

 dish-yellow ; sheath of saw black. Antennae shorter than the abdomen. 

 Wings almost hyaline. 



The <$ has the thorax quite black, antennas longer than the abdomen, 

 which has the second to the sixth segment banded with reddish-yellow. 



Length 5 5| lines. 



This insect is rather like 3-plicatus in form and 

 general coloration, but it may be easily distinguished 

 by observing that the mesonotum bears no black, while 

 the scutellum and the metanotum are black, the 

 opposite being the case with 3-plicatus, which has 

 besides the pleurae, red along their whole extent, 

 instead of only the anterior part. 



A commonly distributed species. It has been 

 taken in Aberdeenshire (Trail), Clydesdale, Glanvilles' 

 Wootton, and in the London district.
