 the village.

 further up, and even flying over the skrees.

 ab. erynnys.

DORSET HYMENOPTERA. 

 By F. H. Haines, D.P.H., M.R.C.S., L.R.C.P. 



The following are some of the less generally recorded 

 Aculeates, noted by me, in this neighbourhood of heath, wood, 

 and down : — 



Formica sanguinea, Latr., Parley heath ; Ponera conti'acta, 

 Latr., two workers. May 23rd, 1913, West Lulworth cliffs ; 

 Myrmica sulcinodis, Nyl., one female, September 9th, 1913, 

 Ringstead. Mutilla europaa, L., not infrequent on the heaths. 

 In 1911 I took a fine female as early as May 27th at Morden, 

 and in 1908 I took a female at Moreton on May 29th. My 

 latest date is October 7th, 1912 — a rather large male, on West 

 Knighton heath. At Arne, on August 25th, 1913, I found a 

 nest oi Bomb us jonellus, Kirb., in a disquieted state, attributed 

 by me to a high tide having reached it. Noting that only 

 workers were to be seen, I carried a portion — only 4f in. in 

 circumference — home. From both larger and smaller cocoons 

 M. europcsa emerged through round, jagged holes : thirteen 

 females between August 29th and September 5th, four males 

 between August 29th and September 10th, but no B. jonellus 

 I still have the fragment under observation. Methoca ichneii 

 monides, Latr., one female, September 11th, 1910, on Godlingston 

 heath; Pompilus unicolor, Spin., one female, September 3rd 

 1910, Arne ; Salius affinis, V. de Lind., two females, July 27th 

 1912, on West Knighton heath, and one female, August 3rd 

 1912, on Studland heath ; Ceropales maculatus, F., common in 

 August, on Angelica; Stignms solskyi, Mor. ; Passahecus cor 

 niger, Shuck. ; Mimesa equestris, F., commoner than M. bicolor 

 Jur., July, on Heracleum ; Gorytes campestris, L. ; G. quadri 

 fasciatus, F. ; G. laticinctus, Lep., one female, Moreton, July 12th 

 1910, one female June 22nd, 1912, and one female and three 

 males in July, 1912, on (Enanthe and Heracleum ; Nysson inter 

 ruptus, F., end of May and June, on Anthriscus and Chcero 

 phyllum ; Mellinus subulosus, F., Cerceris 5-fasciata, L. I have 

 two specimens of an Oxybelus, quite similar to the common 

 0. uniglumis, L., but with pale mandibles ; I think only a 

 variety of it. Crabro tibialis, F. ; C. capitosus, Shuck. ; C. sig-
