ON COLLECTING AND SETTING TIPTJLIBM. 

 A few words on collecting and setting, and then my paper is done. 

 I have collected all my Tipulidce just like butterflies ; a chip box for 

 each, only with small species there is no harm in more than one speci- 

 men being in a box. Care must be taken not to shut the legs against 

 the lid, and if there be any rough splinters inside the box they are 

 very liable to pull off their legs against them. Sweeping for them is 

 almost useless, except with very small species, as it knocks them to 

 pieces. "When brought home in the chip boxes I kill a few at a time 

 in an ordinary cyanide bottle, and set as soon after death as possible, 

 as otherwise the legs are bound to come off ; I use ordinary English 

 entomological pins, pinning the specimens through the middle of the 

 thorax, and leaving them about half-way up the pin ; then I add a 

 circular label (punched with an old gun-wad punch), on the under-side 

 of which has already been written the locality and date. After a little 

 practice this label may be made very useful for arranging the legs and 

 wings ; these latter I ex bend just as one would for a Pterophorus, the 

 legs look best when the middle pair are behind the wing, but often to 

 avoid breaking them off, they must remain under or in front of the 

 wings ; they soon dry, and then do not readily come to harm. The 

 continental method of pinning is to use the very long pins, and push 

 the specimen up at least three quarters of the pin, and only slightly 

 arrange the legs and wings, if at all. I would specially emphasize the 

 labelling, as specimens without a history are almost valueless. 



ADDENDA ET CORRIGENDA. 

 Vol. xxiii, page 118. Put Acyphona imbuta in a separate genus 

 = Chilotrichia, Rossi. Put Ephelia decora, Hal., as a synonym of E. 

 marmorata, Mg. ; I have seen this correction in Haliday's own writing 

 in a " Curtis' Guide " which Haliday sent to Loew, and which Baron 

 Osten-Sacken now possesses, otherwise, as Loew truly remarksj the 

 description seems different. After Limnophila discicollis add L. sub- 

 tincta, Ztt. Limnophila senilis, Hal., is, I believe, the Cladura fuscula 

 of Loew, but is not a true Cladura, in Osten-Sacken's sense ; Professor 

 Mik thinks it will form a distinct genus. Page 119, after Anialopis 

 immaculata add A. claripennis, n. sp. ; before the genus Cylindrotoma 

 put Phalacrocera, Schin., replicata, L. ; after Tipula marmorata add T. 

 signata, Stseg. ; and after T. scripta add T. excisa, Schum. Page 122, 

 at 23, Phalacrocera should come in ; it has a dull blackish appearance, 

 while Cylindrotoma is black and yellow, almost like a Pachyrrhina : at 

 83, Chilotrichia has the sub-costal cross vein at the end of the medias-
