INSECTS IN NORFOLK imOADLAND. 345 



and N. ? salicis-cinerefe at the latter Broad ; Ccphus pygmceus was 

 generally common, and the fine C. linearis occurred in the wet 

 places ab Surlingham and Kockland. Both sexes of Sirex fiirias 

 were cut from their borings in a pine-shed at Horning Ferry. 

 We saw very few Aculeata, and those were common things : — 

 Crahro claripes (female) at Surlingham, C. peltarius at Attle- 

 borough, flying to nest in telegraph-pole; Odyncrns 'parietum at 

 Ormesby and on the Buckenham pontoon ; the only bees were 

 Halictus leticopus and H. cyliiidricus at Winterton and Hickling, 

 respectively, with Andrena minutida (female) at Ormesby, and 

 H. alhipes at Hickling. 



Lepidoptera we studiously avoided, annexing only a solitary 

 Ino statices at Rockland. Only in one place did the glorious 

 Papilio machaon appear, and we feasted our eyes, forbearing to 

 strike so grand a friend. 



Many good marsh things occurred among the Diptera, but 

 here again the weather was all against us. Odontomyia tigrina 

 was swept at dusk at Wroxham, Microclirysa flavicornis and 

 poUta common at Hickling, Beris vallata at Horning, a male 

 Hcematopota pluvialis swept at Surlingham, and a male Clirysops 

 relict us on reeds at Horsey ; Dioctria rufipes at Earlham and 

 Rockland, and Dysimachns trigonua on the Winterton sand-hills, 

 where also were secured two conspicuous grey Tuchinids, which 

 have baffled even Mr. Piffard's attempts to determine. Dohehopids 

 were, of course, abundant throughout the district. PipiDicidiis 

 confusns at Horning ; Chrysognster hirtella {macqnarti) was com- 

 mon, and Liogaster splendida not rare at Horning and Wroxham; 

 Leucuzona lacorum, which does not abound in Suffolk, was found 

 at Earlham ; Pyroplicena * ocymi was generally common ; one 

 example of P. rosarum at Wroxham, with Platychirus fidviventris. 

 Eristalis sepulchralis, far from farm ponds, turned up not rarely 

 at Horning and Surlingham, at the latter of which was also 

 Helophihis lineatas (male, female), with H. versicolor at Rock- 

 land. One of the most abundant flies was Tropidia milesifonnis 

 in all the marshes. Ceromasia ? spectabiUs swept from reeds at 

 Horsey; Morinia nana at Wroxham; Polietes lardaria, in wbich 

 we thought to have a prize, on the wall of St. Beuet's Abbey. 

 The fine Hyetodesia errans along the Yare, and H. ? variabilis at 

 Horning. Melanochelia riparia turned up at Hickling, Hoplo- 

 qaster molUcula at Surlitigham and Horning, and H. bicolor at 

 Wroxham ; Cordt/liira albipes at Rockland, and C. ! apicalis at 

 Surlingham. Both Sciomyza albocostata and Sepedon spinipes 

 were swept at Horning, with Calobata petronella, Ceroxys crassi- 

 cornis, and Notiphila idiginosa, which last was abundant in 

 flowers of Nymvhcm lutea. The pretty little Pteropcectria frondc- 

 scentice from Hickling is the only other species worthy of note. 



■■'■■■ Both the British species of Pyrophcena have occurrcd.to me much niore 

 freely this year in various parts of the country than during any previous ex- 

 perience. Am I alone in this observation ? — C. M.
