being uniserial and the acrosticlials biserial, while the antennae are 

 extensively yellow. It has been found by the late Mr. Verrall, 

 Col. Yerbury and myself at Lyiidhurst (Hants), Porthcawl (Grlamor- 

 gan) , Frinton-on-Sea (Essex) , Orford (Suffolk) , and Snailwell (Cambs.) , 

 in June and July. 



BOLICHOPOBIBJE. 



It may be as well to take this opportunity of placing on record 

 the synonymy of Dolichopus varitlbia, Lundbeck, and Doliclwp^is 

 latU'ola, Verrall. In describing this latter species the late Mr. Verrall 

 said, " Face almost descending to the level of the bottom of the eyes 

 (and yet the species is apparently a Dnlicliopm rather than a Hygro- 

 celeuthus) " which unfortunately is somewhat misleading, for though 

 the face of laticola is rather longer than in picipes, it is typically 

 Dolichopid-like in the way in which the lower part slopes backwards 

 between the eyes over the mouth, and quite different to the flat 

 shield-like lower part of the face in a male Hygroceleuthus. I am 

 sorry to say that this misled Mr. Lundbeck and caused him to 

 re-describe laticola as varitibia in his " Diptera Danica," Part IV, 

 1912. I may add that Mr. Lundbeck has compared the type of 

 laticola. with his varitibia, and confirms the synonymy. 



15. Syntormon mihii, Strobl. I found this very distinct species 

 (which was described from a Spanish specimen) in a small boggy 

 patch of ground near Trevone, Cornwall, when collecting in company 

 with Mr. C. G. Lamb on June 12th, 1912. Its yellowish abdomen 

 with dark dorsal stripe, and in the male its simple basal ioint and 

 dilated and darkened other joints to hind tarsi, and the two stout 

 bristles beneath the middle femora, just before the middle, serve to 



^distinguish it. Becker records its capture in Corsica, G-reece, and 

 fCrete, so it appears to be another of the Mediterranean species found 

 'in Cornwall. 



16. Acropsilus niger, Lw. This genus of Dolichopodidse is new to 

 'the British fauna, and would rvm down by Verrall's " Tables " to the 



neighbourhood of Micromorp^ms ; the face is narrow in the male but 

 "broader in the female, and bearing in that sex a few bristles on the 

 somewhat convex lower part ; the femora are without pre-apical 

 bristles, and the basal joint of the hind tarsi much shorter than the 

 next joint. A. niger is a little known mid-European species, and 

 Mr. C. Gr. Lamb is to be congratulated upon finding a pair near 

 Padstow (Cornwall) in June, 1912.
