a minute or two, when the insect will be found firmly and cleanly 

 attached. 



Some difficulty may be experienced with the larger species, 

 if their tarsi do not lie evenly on the mount at all points ; in 

 such cases the insect should be relaxed, if necessary, and care 

 taken when mounting to fix each tarsus firmly before proceeding 

 to the next. 



Soft-limbed species may be mounted without previously 

 being set. 



C. maxilloxus, L. iiehiilosiis, L. vielunop<i, and il/. atricapilliis, mounted 

 on gelatine (enlarged). 



A glance at the illustrations (somewhat enlarged) of L. me- 

 lanopa, C. viaxillosns, and L. nehidosus on gelatine mounts, and 

 a pinned specimen of M. atricapilliis on a disc of the same 

 material, will give some idea of the pleasing results obtainable 

 by the gelatine method, which is especially useful for smaller 

 species than those shown in the photographs. 



No doubt Diptera, Hemiptera, &c., could easily be mounted 

 on gelatine without pins, but as there are few insects abroad 

 at the moment of writing I am unable to make the experiment. 



I might mention that Messrs. Watkins & Doncaster have 

 undertaken to supply these mounts.
