At sugar. — A large number of species 

 may be taken by this means ; get half a 

 pound of common treacle and put to it a 

 desert spoonful of rum, apply this mixture 

 with a new paint brush to the trunks of trees 

 about five feet from the ground in woods, 

 lanes, gardens, &c. Apply the mixture at 

 dusk, and after dark go over the patches with 

 a bull's-eye lantern. The species to be taken 

 by this means are very numerous, and it 

 would take up too much space to specify 

 them all. They should be put in chip boxes, 

 one in a box, and left till morning, if killed at 

 night, as soon as they are taken their bodies 

 are full of sugar, which will afterwards have a 

 tendency to cause them to grease. In the 

 morning eggs will cften be found in the boxes, 

 and by referring to p. 209 you will see how to 

 rear perfect moths from these. Anyone 

 desirous to assist us with the history of 

 British Lepidoptera we have begun, we shall 

 be pleased to send a list of the species of 

 which we want eggs or larva for figuring. 



NATURALIST. 

 COMMON ICHNEUMONS. 



By S. D. Bairstow, F.L.S. 



IV. TROGUS LUTORIUS, Grav.Wesm. 



Do you wish to see a great ichneumon ? 

 Do you desire to view an insect which cannot, 

 like most of its compeers, lay claim to any 

 great merits of beauty, whose bosom friend, 

 one would think, is closely allied to a poma- 

 tum pot ? Then allow me to introduce and 

 recommend to your notice Trogus lutorius, one 

 of the largest, and one of the most singular 

 looking parasites in the British List of 

 Ichneumonida. It being large has therefore an 

 eminent claim to be placed amongst our 

 illustrations, and further, as our own opinion 

 is, that it may be safely classified amongst 

 the fairly common ones. Of the genus 

 Trogus, Marshall mentions but two species in 

 his catalogue, viz. ; T. lutorius and T. albo- 

 guttatus (this latter I have bred from Orgyiapu- 

 dibuuda taken in a fir wood, at Llanrust, North 

 Wales) . To these, most probably, we might 

 add the near ally of lutorius, Trogus exaltorius. 

 I have never captured our greasy ichneumon 

 upon the wing, but I have several times seen 

 it in Entomological collections, pinned side 

 by side with r ,ne or another of the Sphinges. 

 It is a parasite on the larvae and r. upas of 

 large-bodied moths. In my note-book I have 

 it labelled thus, " Communicated as infecting 

 kvvas of pure of Sphinx lignrri, Sr.erinthus 

 Oi llatus, Maci ?glossa stellatarum , and A cherdntia 

 atropos. Personally I have only reared it 

 from ocellatus. 



The body of lutorius is (in an average speci-
