ON COLLECTING DIPTERA. 

 By E. Brunetti. — No. III. 



{Continued from £. 31.] 



IN the Coleoptera, the order in which, perhaps, card- 

 ing attains its climax, instances have come under 

 my own immediate observation, of such large genera 

 as Tenebrio, Timarcha, and Broscus, being carded, and 

 Gastrophysa and Coccinella pinned, it being needless 

 to add how irregular an appearance a collection 

 presents when the size of the insect is utterly 

 disregarded, and each collector follows his own sweet 

 will about setting. 



So far as beetles are concerned, I think it would be 

 a good plan to endeavour to pin all the species of 

 one genus, and to card all those of another : excep- 

 tions, of course, will occur, but the rule could be 

 observed in the large majority of cases. 



As regards the actual setting, it is quite unneces- 



sary to give the exact positions the legs and wings 

 should take, but jit may be remarked that good 

 setting is by no means indispensable. 



Lepidoptera may be collected for their beauty, 

 and perfect setting be considered a sine qua uou, but, 

 as Diptera, if collected at all, will not be chosen for 

 their personal attractions (if the expression be per- 

 missible), but for purposes of study only, good 

 setting may often be dispensed with ; though it 

 cannot be denied that a well-set specimen appears to 

 better advantage in a cabinet and can be examined 

 with less difficulty than an unset one. 



For the benefit of those who care to set well, let 

 me remark that the wings should be quite horizontal, 

 inclining slightly forward, and two pairs of legs 

 placed behind the wings, not before them ; care 

 should be taken to keep the middle pair from being 

 under the wings. 



Use thin pins, but ones of moderate length ; let 

 there be a good half-inch between the point of the
