doscribetl, resembles those of other species of Oxycera, but differs in 

 being armed on the ventral side of the penultimate segment with a pair 

 of sliarp, curved, spine-like horns, much larger than those found in 

 Odonfomyia. Recently, in examining a lot of Stratiomyid larvae, I 

 found just such a structure in the American genus Enparyplius. As 

 this genus is not recorded from Britain by Verrall, I was puzzled as to 

 the position of Haliday's larva. I therefore tried out my specimens of 

 Euparyphits by Verrall's tables, and found that they would fall in with 

 O. tenuicoDiis Macq. by reason of the antennal structure, and am now 

 inclined to believe the two are congeneric. Mr. Verrall gives O. lonyi- 

 cornis Dale as a synonym of O. tenuicornis, and further states that 

 Pale's original description was obviously written by Haliday. It 

 appears quite possible, therefore, that Haliday's larva may belong to 

 O. tenuicornis instead of to O. morrisii. The structure of the larva 

 certainly warrants such assumption. The fact that the larva was col- 

 lected in Ireland, though the adults of O. tenuicornis have not yet been 

 recorded from that island, offers no particular difficulties, since the latter 

 has a rather wide European distribution. The locality in which Haliday 

 found the larva — " among the Confervae and Marcliantia on the face of 

 a dam serving for an outlet to the superfluous water of a mill-race and 

 continually moistened by a shallow but rapid fall of running water " — 

 describes just as precisely the place on Cascadilla Creek, at Ithaca, N.Y., 

 where my larvae of Euparyphus hrevicornis Loew were found. The 

 opinion that 0. tenuicornis is generically distinct from Oxycera is 

 shared by other entomologists, since Villeneuve erected the name 

 Vanoyin scutellata for a fly which Verrall considers identical with 

 0. tenuicornis. The characters ascribed to Vanoyia Vill. apply equally 

 Avell to Euparyplms Gerstaecker .

Coleoptera on the mndhills, Monifieth, Firth of Tay. — With reference to 

 Prof. T. Hudson Beare's inteie^ting notes on Coleoptera on the sandhills at 

 CTiillane [antea, p. 89), I send a note on snuie of the beetles I have fovmd on tlie 

 sjuidhills near MoniHeth on the north side of the Tay. It is probable tliat 

 these Siindhills, which are extensive, have never been collected over. Insec;s 

 are plentiful, and the beetles now recorded have been taken at various times 

 ■while searching for Diptera. Most of the names were confirmed for me by the 

 late W. E. Sharp. C/eunus siilcirostris L. is never common here, and I have 

 seldom seen it on the bare sand, but it may be found by searching thistles ; 

 Otiorrhynclius utroapterus De G. is alwajs common, and so is O. ovatus L.,
