collector, at about the same time as I met with it at Gribraltai*. I am 

 able also to give a few new localities, times of appearance, and varietal 

 names, of certain species which have already been recorded. 



I am indebted to Mr. J. H. Durrant and to Mr. L. B. Front, also 

 to Commander J. J . Walker, for kind assistance in identifying many 

 of the more difficult species. My thanks are no less due to Sir Gr. F. 

 Hampson, Bart., for facilities and kind assistance given at the Natural 

 History Museum. 



Eighteen species, chiefly Bliopolocera and Zyijivnidtv, taken by 

 Mr. Gr. 0. Sloper at Grranada, who kindly presented me with specimens 

 at Gibraltar, are included in the list. During my stay in G-ibraltar 

 I also took about 180 species of insects of other Orders, spiders, &c. ; 

 lists of some of these appear at the end of this paper, through the kind 

 assistance of several well-known entomologists.

DESCRIPTION OF A NEW SPECIES OF TACH7S. 

 BY D. SHARP, M.A., F.R.S. 



Tachys (Tachyura) walkerianus, s^j. n. 



Nigerrimns, pernitidiis, antennis piceo-nigris (articulo hasali plus minusve 

 dilutiore), fenioribus piceo-testaceis, tibiis tarsisque sordide testaceis ; sat 

 depressus ; thorace fortiter transversa ; elytris quinque-striatis, striis fortiter 

 punctatis. Long. corp. 2-2^ mm. 



Allied to T. parvulus, but more robust, less depressed, with a 

 broader, more transverse thorax, darker antennae, palpi and legs, and 

 with more deep and strongly punctured striatiou of the elytra. The 

 two species are extremely easy to distinguish, and the characters of 

 T. ivallieriamcs are almost invariable in a large series of specimens, 

 except that when immature the legs and base of the antennae are a little 

 lighter in colour. 



I found three examples of this species here in the spring of last 

 year and thought they would prove to be the rare T. parvulus ; with 

 my daughter to help me we have secured a very fine series this year, 

 proving the insect to be quite distinct. I believe Tachys parvuhis has 

 been recorded as occurring in the New Forest, but I anticipate the 

 specimens will prove to be T. waTkerianus. 



The insect is found in wet moss by the side of a little stream, in 

 company with Actohius ytenensis, Ghsetocnema arida, and a nondescript 

 Homalota allied to H. exilis. The larvae of a large Microdon occurred 

 in the same moss, no doubt in connection with Myrmica which was also 

 abundant.
