may be able to consult the same. I have also had the pleasure of breeding Leptoce- 

 rus filosus, Linn. , this season. The larva lives in running water, and feeds on aquatic 

 plants, and when full-fed seals up its nearly straight case, which is made of a horny- 

 like substance, mixed with fine grains of sand, and covered with a coarser sand out- 

 side. When the imago is about to emerge it cuts itself a little trap-door, which opens 

 on a hinge, the door itself being perforated in the centre, corresponding to a hole at 

 the opposite end of the cocoon, to allow for the free circulation of water. The pupa- 

 cases are attached to bits of sticks, &c, at the bottoms of the straws. The insect 

 emerged on June 1st. This insect fades from nearly black to rusty brown, even in the 

 cabinet, where it is not exposed to the light. 



Limnephilus vitratus. I have bred this species this year. The larva-case is com- 

 paratively fragile, composed of silk and small bits of stick laid longitudinally, and 

 weighted at the posterior end with small stones. 



Leptocerus bimaculalus of Stephens. This rare species was given me by the Rev. 

 J. Hellins, who captured it in his garden, in August. 



Perla marginata. This rather uncommon species I took at Dunsford this season. 



Psocus vittatus. I took a pair of this local species near Exeter, October 18th. —

Preserving Ephemera. — The author of the useful " Synopsis of British Epheme- 

 ridse," in the * Entomologist's Annual' for 1863, complains of the difficulty of pre- 

 serving specimens of that order of insects. Did it ever occur to him that they may be 

 pressed and dried in blotting-paper, like flowers ? I have before me a May-fly, which 

 I caught in the summer, as a model for an artificial fly, and placed between two 

 pieces of flannel in my fly-book. It has undergone no alteration, either in form or 

 colour, since the day of its capture, and may be handled without fear of injuring it. —

Correction of Errors. — There are two errata in the description of the larva of E. 

 arceuthata (Zool. 8343). In line 10, page 8343, " annoying distinctive differences" 

 should be ", unvarying distinctive differences ;" and at line 24 of the same page, " and 

 tip of central dorsal line " should be " anal tip of central dorsal line." — H. Harpur 

 Crewe.
