Inserts. 



Mel an dry a canaliculate. One specimen, in company with numbers of the common 



M. caraboides, under bark. 



Conopalpus testaceus. A few specimens from whitethorn. 



Cryptocephalus bipustulatus. The habits of this species certainly do not tend to 

 unite to C. lineolu, though in form and sculpture it would be hard to find much 

 difference. 



Sundry genera remain as yet unexamined; e.g. Cerylon, of which I cannot but 

 consider that w e have more than two species ; the red specimens that T have obtained 

 are almost all identical with specimens of C. deplanatum, Gyll., that I have received 

 from the Continent, but I have two that resemble the C. angustatum, Er. — G. R.

If any sawfly is aptly named it is the species we are now about to 

 treat of, for, having regard to this insect in its perfect state, it is ex- 

 tremely difficult to distinguish it from the imago of Lophyrus Pini 

 described at page 7887. Although there are some general characters 

 by which the species may be distinguished, they are still so nearly 

 alike that the separation of individual specimens is very difficult. On 

 the other hand, the larvae are so differently coloured that there is no 

 danger of confounding the two species in that state. To any one not 

 acquainted with these facts from a study of the works cited above, 

 and who, having first reared one of these species, is afterwards 

 watching for the appearance of the imago out of the cocoons of the 

 other, it is somewhat surprising to get an insect the male and female 

 of which differ greatly from each other, but are both respectively pre- 

 cisely like a species which he had reared from entirely different larva:.
