conspicuously pale basal joint of the antennae affords a strongly 

 distinctive character. The genital lamellaj have the basal part 

 long, thin, and black, the apical pari short, not much swollen and 

 broven, with its outer lamellEe whitish, threadlike, but broad at 

 tJie base, and not very long. I do not think that this species has 

 been recorded since Loew described it from Halle in 1859. 



The adding of the genua Sf/stemcs and all its known species to 

 Britain in four years, through breeding them, is a remarkable occur- 

 rence, and shows how much may be done by distinct methods of 

 collecting.

 Mr. C. a. Lamb. 



The British DolichopodidcB now include 41 genera and 204 species, 

 as against Walker's 15 genera and 138 species ; of course the number 

 of genera has been mainly increased by the breaking up of the pre- 

 vious large and in many cases heterogeneous genera, but (as six of 

 Walker's species have been omitted) there has been an increase of 

 over 50 per cent, in the species, and I think as many more may still 

 be added without much trouble. Of the 132 species described by 

 Walker I possess all but five, and I have seen specimens of all except 

 Hygroceleuthus latipennis, Jlercosfomus fulvicaudis, and Thinophilus 

 flavipalpis.

FURTHER NOTES ON MANX COLEOPTERA. 

 BY J. E. LE B. TOMLIN, M.A., F.E.S. 



The following notes are in continuation of my paper in Ent. Mo. 

 Mag., 1904, pp. 177 — 9, and are the outcome of about a week's col- 

 lecting in the Isle of Man at the end of May, 1904. I group the 

 species geographically as before, and to these four districts I now add 

 a fifth — as the result of a visit to the summit of Snaefell, — and a 

 sixth for the high land of Bradda Head. 



Though 1 only collected specimens of twenty-four species on the 

 top of Snaefell, there was quite enough material to confirm the alpine 

 nature of its fauna, as evidenced by such forms as Arpedium hrachy- 

 pterum, Gr. (common), Homalota eremifa, liye (very abundant), 

 Otiorrhynchus mau?'us, GylL, Patrohiis assimilis, Chaud., and PteroS' 

 tichus vitreus, Dj. (both common).
