NOTES ON SOME BEITISH DOLIcnOPODIDJE, WITH DESCRIPTIONS 

 OF NEW SPECIES. 



BY G. n. YEEEALL. 



(continued from Page 36.J 



Since my commencement of this paper, I have captured several 

 species of Dolichopus and Oymnopternus which require noticing, and 

 I have therefore recommenced with those genera. 



Dolichopus uebajjus, Meig. — Abundant at Upware, in the Cam- 

 bridgeshire Fens, last July. 



D. PUNCTicoEXis, Zett. — When I described D. mediicornis (p. 32) 

 that was the only species of the group with which I was acquainted ; 

 since then I have caught a species which I believe to be Zetterstedt's 

 D. pimcticornis. Its principal characters are included in the following 

 diagnosis : 



D. puNCTicoENis, Zett. Dipt. Skan., ii, p. 536. 



I d* ? • Viridis,facieflavido-oehraced; antennis mediocribu^, articulo prima 

 snhtiis ad apicem obscure ochraeeo ; fronte viridl, oculorum ciliis inferiorihus 

 Jlavis ; abdominis incisuris nigris ; pedibus flavis, coxis posterioribus cinereis, 

 tarsis nifjris, antcriorum a7'iiculis basalibus flavidis apice fusco-nigris, tibia- 

 rum posticarum apice fere ad tertiam 'partem determinate nigro, sub-incras- 

 sato ; alis sub-hyalinis, vena discoidali leniter flexuosd max ante apicem alee 

 excurrente. 



$ . Facie flavido-ochracca sub-a7igustd, pedibus simplicibus, sod tibiarum 

 anticarum apice pilum sub-elongatum ferente, Tiypopygii mediocris lamellis 

 ovatis, minorihus, sordide albidis, apice et superne nigro-marginatis ; cosid ubi 

 vena sub-costalis excipit longe incrassatd. 



? . Facie ex-albidd, antennis brevioribus, tibiarum posticarum apiice ad 

 quintam partem nigra. 



From D. mediicornis this species may be easily distinguished by 

 its ochraceous and much narrower face, by the basal joint of the an- 

 tenna? being only somewhat ochraceous at the tip of the first joint 

 beneath — " articulo basali subtus ad apicem puncto parvo luteo a?grc 

 " obscrvando " (Zett., I.e.), the antennae are also slightly shorter, and 

 the third joint less rounded at the tip. The front coxa; bear more 

 numerous small bristles (the front coxa> of D. mediicornis being some- 

 what denuded), the front tibia? bear a small thin binstle inside at the 

 tip, wliich is rather inconspicuous, the middle tarsi are paler, having 

 the two biisal joints pale with dark tips, the hind tibiae have nearly the 

 apical third abruptly and conspicuously shining black, slightly dilated, 

 and with a peculiar short groove at the tip outside ; the lamellae of the
