touching eyes of the male, and its almost entirely black front 

 coxas ; beyond these characters it is distinguished from C. 

 cupreus by its much more bristly and more ciliate front and 

 hind tibia?. For many years I considered a number of speci- 

 mens caught at Totlaud i^ay in the Isle of Wight as distinct, 

 and it is possible that they are C. melampodius Lw. which is 

 only known from Sicily, but while I think ihey are brighter 

 green than either C. blepharosceles or C. melampodius, 1 

 think they must have more ciliate tibiae than C. melampodius, 

 and the front coxae more tending to dirty whitish than 

 either, though not so much as in G. cupreus. At present I 

 refrain from separating them from G. blepharosceles, though 

 similar specimens have been taken by Dr. U. Sharp in the 

 New Forest. 



10. G. monochoetus, Kow. : I am obliged to refer to this species a very 



small female taken at Abbey Wood near Erith on July J 7th, 

 1874. 



11. G. microcerus Kow. : 1 originally introduced this species as British 



from a few specimens taken at Waterbeach in Cambridge- 

 shire, and not as I then stated from Upware which is a short 

 distance away on the other side of the Cam. I am still of 

 opinion that they were correctly identified, and Kowarz 

 himself has corroborated one of the specimens. I think the 

 species is slightly smaller than its allies, but none of the 

 British specimens show any sign of reddish basal joints of 

 the antennse. I have since taken similar specimens at TJp- 

 ware, Brandon and Thetford, all of which are within a few 

 miles of Waterbeach. 



12. C. gramineus Fall. : I still have no doubt about this being the 



very common little species, distinguished by its bright colour, 

 moderately small and moderately blunt antennse, and dis- 

 tinctly ciliated hind tibiae. 1 believe it occurs freely from 

 Penzance to liannoch, but in searching for the closely allied 

 species I have allowed my series to get into a very unsatis- 

 factory state ; as, however, it used to occur on the leaves of 

 currant bushes in my garden I may probably renew my 

 series. I think it possible that it occurs in much drier 

 localities than its allies. 



13. G. angulicornis Kow. : I included this species in the Second 



Edition of my List of British Diptera on the strength of 

 a number of specimens taken at Lyntou in North Devon on 

 Juno 20th, 1883. The species is one of the largest of the 

 " gramineus " group, and has the antennae of the male with 

 the third joint rather longer and distinctly more pointed.
