beneath at the extreme tip of the basal joint, thereby showiiif; the 

 close relationship of the species to the D. nubilus group. Wheu the 

 front femora are darkeued above the front co.\aB are also more 

 darkened. It is very closely allied to D. latilimbatus, but that has 

 the flexure of the discal vein less abrupt, the front coxaj paler with 

 whitish shimmering, and the hind femora slightly dusky at the tip ; it 

 is, however, so closely allied that I should usually not like to name 

 any single specimen 



37. D. mediicornis Verr. : 1 have nothing to add to my notes on this 



species as given in this Magazine in July, 1.S75. It had 

 then occurred in considerable numbers in the New Forest in 

 June, 1871, and it occurred there again in 1875. 



38. D. lineaticornis Zett. : Mr. F. Jenkinson took two males of a 



DoUchopus at Cambridge on July 15th, 1901, which I cannot 

 satisfactorily identify. They appear to me to be either D. 

 lineaticornis Zett. or D. grandicornis Whlbg. They agree in 

 size with D. lineaticornis, which is distinctly larger than D. 

 puncticornis Zett. and D. mediicornis Verr., and they also 

 seem to me to agree with it in the wholly grey posterior 

 coxae (which, however, are slightly rufescent about the tip of 

 the hind pair in Mr. Jenkinson's specimens), and in the 

 length of the antenuse, which should be slightly less than 

 the transverse section of the head. On the other hand the 

 face instead of being "'flavido " as in D. lineaticornis is more 

 the " aureo-ochraceo " of D. grandicornis. The costa has a 

 slight (so slight as to be easily overlooked) swelling about 

 the end of the subcostal vein, while D. lineaticornis and D. 

 grandicornis are said to have " sfigmate omnino nulW and 

 " stigmate nullo.'" My D. mediicornis is smaller and has the 

 front coxa; more denuded of tiny black bristles and all the 

 tibiffi with weaker bristles, besides having the face ''Jlavido- 

 alba." Walker professed to recognise B. lineaticornis as 

 British.aud described the face as "flavido'' or "ochre-yellow ;" 

 I therefore at present accept the name of D. lineaticornis 

 for the two specimens caught at Cambridge. 

 39. D. strigipes Verr. : this remarkable species occurred at Fawley 

 in the New Forest on June 21st, 1875, in I think the old 

 salterns which were there. In 1889 Becker re-described it 

 as D. aratriformis from salterns between Spalatro and Eagusa 

 in Dalmatia ; he distinguished the female as having rather
