THE MOUNTING AND PRESERVATION OF DIPXERA. 31 



If the specimen is one with very long and delicate legs, so 

 that pinning straight through the thorax would he liable to break 

 these off, it may be pinned a little towards the side, the pin 

 emerging from the other side just above the coxae. The specimen 

 is even then more or less perpendicular.* This applies chiefly to 

 TiPULiDjE. The wings should never be crossed over the abdomen 

 but allowed to stand out in a natural manner sufficiently clear 

 of the body to allow an uninterrupted view of every part of the

 angles to the body after the fashion adopted in " setting " 

 Lepidoptera. 



The legs should not be allowed to fold up close under the 

 body, but be pulled out sufficiently clear for one to examine 

 easily all parts of them and of the ventral surface of the insect, 

 and at the same time not allowed to stick out at ungainly angles 

 (a prevailing disposition of many TIPULIDJE) threatening des- 

 truction every time they are touched : nor should they hang down 

 (this also especially applies to TIPULID^E) so that they touch or 

 nearly touch the bottom of the cabinet drawer. 



The same rule applies to the antennae. This is because there
