ON TWO SPECIES OF DOLICIIOPODID.E TAKEN IN SCOTLAND. 

 I3r G. H. VEKEALL, F.E.S. 



Since the coiieluaion of my paper on the Brititih Dolichopodidod, 

 two species have been taken by Col. Terbury in Scotland which 

 require notice. 



DoJichopus argyrotm-sis Wahlb. : Col. Yerbury caught one male of 

 this species at Nethy Bridge on June 19th. It is very closely 

 allied to D. pemiafus and D. signatus, but is readily distinguished 

 by having the last three joiuts of the middle tarsi silvered in the 

 male. 



Porphyrons gravipes Wlk. : when searching for more specimens of P. 

 patula, Col. Terbury, besides taking that in considerable numbers 

 also caught a 1 )t of a species which I have little doubt is the true 

 P. gravipes Wlk. (= long ilamellalus Kow.). It differs from P. 

 patula by its slightly smaller size, simple arista, shorter genital 

 lamellae (though still very long), and quite black hind femora, 

 which latter character seems to be constant. lie took P. gra- 

 vipes at Nairn and Nethy Bridge from May 30th to June 16th. 

 P. patula occurred at the same localities and also at Brodie. P. 

 rivalis was abundant at Nairn, Brodie, and Nethy Bridge from 

 June 3rd to 17th. 



Newmarket : November, 1905. 



Se-occurrence of Quedius nigrocaeruleu.i, Rey, in Suffolk. - On September 1st 

 last I again captured this species, four ? specimens turning up in a woody fungus 

 on an elm in a hedgerow near Oulton Broad. The fungus was full of the larvae of 

 Orchesia micans, Pz., upon which the Quedkis was probably preying. I should 

 very likely have obtained more specimens if I had not knocked the fungus off the 

 tree trunk so as to scatter it in the hedge, the piece from which I obtained the 

 beetles having formed but a small portion of the whole. The four specimens 

 previously recorded for this country were found in bees' nests, or in or about 

 rabbit burrows, and Rey considers it a cave and cellar species, so it appears to have 

 very diverse habitats. — E. C. Bedwell, " Elmlea," Clevedon Road, Norbiton :

Megacronun fonnosus, Gr. — While on the subject of Bold's insects, it is as well 

 to mention that no specimen oi Slegacronusformosus is to be found in the Newcastle- 

 on-Tyne collection. The name appears with a " ? " in Bold's Catalogue, and this note
